AllTalk Installation issues

🟨 curl Certificate Validation Error: CRYPT_E_NO_REVOCATION_CHECK

Explanation and Fix

This error occurs when curl cannot validate an SSL/TLS certificate, often due to issues with your machine’s root certificates, internet connection, or network restrictions preventing contact with a Certificate Authority (CA). This issue is unrelated to AllTalk or its installer—it’s specific to curl's handling of certificates when downloading files from GitHub. This error is out of scope for support on here, so the below is only a general guide on the issue.

Example Error:

curl: (35) schannel: next InitializeSecurityContext failed: CRYPT_E_NO_REVOCATION_CHECK

Explanation:

The error CRYPT_E_NO_REVOCATION_CHECK typically means:

  1. System Clock Issues: An incorrect time or timezone on your machine can prevent certificate validation.
  2. Outdated version of CURL: Some older versions of CURL need updating,
  3. Outdated Root Certificates: Your machine’s root certificates may need updating.
  4. Network or Firewall Restrictions: If the system cannot contact the Certificate Authority (CA) to confirm the certificate’s validity, the check may fail.
  5. Internet Connection Problems: Temporary internet issues or restricted network settings can also prevent successful communication with the CA.

Troubleshooting Steps

  1. Ensure Correct System Time and Date
    Make sure your system time, date, and timezone are accurate. Certificates depend on correct timestamps to verify their validity.

  2. Update curl to a new build
    Sometimes newer versions of curl handle certificates differently. Updating to the latest version from curl's website has been known to resolve issues in the past, so this is highly recommended as a troubleshooting step.

  3. Check Internet Connection and Firewall Settings

    • Internet Connection: Ensure you’re connected to the internet and that the connection is stable.
    • Firewall or Network Restrictions: Sometimes firewalls or security software may block the certificate validation process. If possible, temporarily disable or adjust firewall settings to see if it resolves the issue.

  4. Update Your System
    An outdated system can sometimes have missing certificates or certificate management tools. Run a system update:

    • Windows: Use Windows Update to get the latest updates.
    • Linux/macOS: Run your package manager’s update commands.

  5. Update Root Certificates
    ⚠️ Proceed with caution: Updating certificates can involve advanced system changes.

    • On Windows: Run certutil -generateSSTFromWU roots.sst in PowerShell or Command Prompt to update root certificates.
    • On Linux/macOS: 
      sudo apt update && sudo apt install --reinstall ca-certificates   # Debian/Ubuntu
sudo update-ca-certificates                                       # Update cert store

Additional Context on Certificate Validation

Certificate validation checks occur locally on your machine, but they may also involve communication with a Certificate Authority (CA). Here’s a simplified explanation:

  1. Local Certificate Verification: Your machine first checks its local certificates to confirm the chain of trust.
  2. Certificate Authority (CA) Communication: If network access is available, the system may connect to the CA to confirm that the certificate hasn’t been revoked. This can happen through:
    • CRL (Certificate Revocation List): A list of revoked certificates provided by the CA.
    • OCSP (Online Certificate Status Protocol): A real-time check with the CA to verify the certificate’s status.

If your internet connection is unstable, if network access is restricted by a firewall, or if your machine’s certificates are outdated, this process may fail, resulting in errors like CRYPT_E_NO_REVOCATION_CHECK.

Summary
Most validation happens locally, but a final revocation check (CRL or OCSP) often requires internet access. If internet access is restricted or there are issues with local certificate configurations, this check may fail.

🟨 Pip Dependency Resolver Warning: Coqui-TTS and Transformers Version Conflict

Explanation and Resolution

During the installation of requirements, you may encounter the following warning:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
coqui-tts 0.24.1 requires transformers<4.41.0,>=4.33.0, but you have transformers 4.43.3 which is incompatible.

Explanation:

This warning is related to a version conflict between Coqui-TTS and the Transformers library. It's connected to the "TypeError in Transformers Library with Coqui XTTS TTS Engine" issue discussed earlier.

Key points to understand:

  1. Coqui-TTS and the XTTS engine currently require Transformers version 4.40.2 for generating streaming audio.
  2. Other TTS engines (like Parler-TTS) may attempt to install a later version of Transformers.
  3. This conflict primarily affects streaming audio generation with the Coqui XTTS engine.
  4. Non-streaming audio generation is not affected by this issue.

Impact:

  • Streaming audio with XTTS: Affected (requires Transformers 4.40.2)
  • Non-streaming audio with XTTS: Not affected (works with any Transformers version)
  • Other uses (e.g., Kobold): May be affected if using XTTS with streaming audio

Resolution:

To resolve this issue and enable streaming audio with XTTS:

  1. Downgrade Transformers to version 4.40.2:

    pip install transformers==4.40.2

  2. Be aware that this may generate a dependency warning for Parler-TTS, but it should still function correctly.

Important Notes:

  • This is a temporary solution until the Coqui-TTS engine is updated to support newer versions of Transformers for streaming audio.
  • AllTalk is not responsible for the maintenance or upkeep of the Coqui-TTS engine.
  • You can re-run the setup process and reapply requirements in the future if you need to change this configuration.

Future Updates:

The Coqui-TTS team is working on updating their engine to support newer versions of Transformers. Once this update is released, it should resolve the conflict without requiring a specific version downgrade.

Recommendation:

If you primarily use XTTS for streaming audio, it's recommended to downgrade Transformers to 4.40.2. If you don't use XTTS streaming or can work without it temporarily, you may keep the latest version of Transformers installed.

🟨 {something} Encountered problems while solving: package {something} is excluded by strict repo priority

Explanation and Fix

This error occurs due to strict channel priority in Conda, which prevents packages from lower-priority channels (like conda-forge) from being installed, even if explicitly requested. It typically happens when Conda is configured to prefer packages from higher-priority channels (e.g., defaults) over others, causing certain packages to be excluded.

To fix this:

  1. Ensure you're using the correct Conda environment:

    • On Windows: Run your environment setup script or locate conda.exe in your system.
      You can often find it in the Miniconda or Anaconda installation directory: 
      C:\Users\<YourUsername>\Miniconda3\Scripts\conda.exe
      or 
      C:\ProgramData\Anaconda3\Scripts\conda.exe
    • On Linux/Mac: Locate conda by running: 
      which conda

  2. Check if there is a system-wide Conda installation: There may be a global Conda installation on your system, separate from the environment currently being set up. To confirm, search for other installations of Conda:

    • On Windows: Look in C:\Program Files or C:\ProgramData directories for global installations.
    • On Linux/Mac: Check common global installation paths like /opt/anaconda3/ or /usr/local/miniconda3/.

  3. Change the channel priority to flexible: Run the following command to allow Conda to consider packages from lower-priority channels like conda-forge:

    conda config --set channel_priority flexible

  4. Install the required package: After changing the priority, you can now install the package without encountering the error:

    conda install -y conda-forge::ffmpeg

By setting channel priority to flexible, Conda can use packages from any listed channel as long as they fulfill the dependencies, rather than strictly preferring packages from high-priority channels.

Conda's documentation on channels can be found here https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-channels.html

🟨 error: command 'gcc' failed: No such file or directory

Explanation and Fix

This error occurs on Linux systems when trying to install Python packages that require compilation of C extensions. It happens because the GNU Compiler Collection (GCC) is not installed on the system.

Python often relies on C extensions for performance-critical parts of packages. When installing such packages, Python uses the system's C compiler (typically gcc) to build these extensions. If gcc is not available, the installation fails.

To fix this:

  1. Install the necessary compilers using the following command:

    sudo apt install gcc g++

  2. After installation, retry the Python package installation.

Note: You may need to install additional development libraries depending on the package you're trying to install. For example, Python development files might be required:

sudo apt install python3-dev

After installing gcc and any necessary development libraries, remember to rerun your package installation command.

Finetuning Issues

🟥 The OrderedVocab you are attempting to save contains holes for indices [XXXX, XXXX], your vocabulary could be corrupted!

Explanation and Fix

This error typically occurs when something has been corrupted or interpreted incorrectly by the Transformers library (Huggingface) during dataset processing or within the model's config.json file.

Example Error:

The OrderedVocab you are attempting to save contains holes for indices [XXXX, XXXX], your vocabulary could be corrupted!

Likely Cause:

This is most likely due to an upstream issue in Coqui's scripts or Huggingface's Transformers library, where the dataset or vocabulary becomes misaligned.

Suggested Fix:

The simplest solution is to rebuild your training dataset and try again. This usually resolves the issue.

Future Considerations:

If this error becomes frequent, I will add extra validation checks into the finetuning process to inspect datasets for potential issues. However, since this is likely an upstream issue (involving third-party libraries), it may not be fully resolvable within AllTalk.

General Issues

🟪 torch.cuda.OutOfMemoryError: CUDA out of memory error. Tried to allocate XXX MiB. GPU 0 has a total capacity of XXX GiB of which 0 bytes is free.

Explanation and Troubleshooting Steps

This error occurs when your GPU’s VRAM (Video RAM) is fully allocated, and PyTorch is unable to reserve the additional memory required for a task. This may happen with demanding tasks, such as TTS generation or model fine-tuning, which can quickly exhaust VRAM, especially on GPUs with lower memory capacity (e.g., 6GB or less).

Example Error:

torch.cuda.OutOfMemoryError: CUDA out of memory. Tried to allocate 14.00 MiB. GPU 0 has a total capacity of 6.00 GiB of which 0 bytes is free.

Explanation:

The CUDA out of memory error signifies that:

  1. The GPU is at its VRAM capacity, preventing the allocation of additional memory for the current process.
  2. The specific memory requested and the GPU’s total VRAM may vary, but the error indicates an inability to free up sufficient VRAM for the next operation.

Troubleshooting Steps

1. Free Up VRAM Before Running the Application

  • Restart the application or your computer to clear any unused GPU memory.
  • Close other GPU-intensive programs that may be using VRAM, such as games, graphics software, web pages with lots of images or other AI applications.

2. Adjust Batch Size or Model Parameters

  • If applicable, reduce the batch size or modify parameters that may increase VRAM usage.
  • When finetuning you can adjust a few settings to potentially improve the situation, Memory Management Help Link 1 and Help Link 2

3. For Windows Users with NVIDIA GPUs: Enable or Disable Shared Memory Fallback (Optional)

In NVIDIA drivers version 536.40 and above, a “shared memory fallback” feature allows applications to use system RAM if the GPU runs out of VRAM, which can prevent crashes but may reduce performance. Disabling this setting may help maintain performance stability but could cause the application to crash if VRAM maxes out. Enabling it will allow your Windows system to use System Ram as GPU VRAM, but will slow things down and can still result in out of memory issues.

Steps to Disable Shared Memory Fallback:

  1. Open Task Manager and locate the path of the python.exe process running your application. (For example: "C:\path\to\python.exe")
  2. Open the NVIDIA Control Panel (right-click on the desktop and select “NVIDIA Control Panel”).
  3. Go to Manage 3D Settings and navigate to the Program Settings tab.
  4. Click Add to select a program, then browse and select the python.exe file noted in Step 1.
  5. Under CUDA - Sysmem Fallback Policy, set the value to Prefer No Sysmem Fallback.
  6. Click Apply to save the changes, and then restart the application.

Re-enabling Shared Memory Fallback:

  • Return to the NVIDIA Control Panel > Manage 3D Settings > Program Settings tab.
  • Select the relevant python.exe file and set CUDA - Sysmem Fallback Policy to Driver Default.
  • Click Apply, and restart your application.

Note: This feature is available only on Windows. Linux currently does not support shared memory fallback.

4. Linux Systems: Check System RAM and GPU VRAM Limitations

  • Linux does not support shared memory fallback for VRAM, so VRAM constraints are stricter. Ensure your system has sufficient VRAM and system RAM to meet your application’s requirements. Consider upgrading your GPU if you regularly encounter this limitation.

5. Consider Reducing Model Complexity

  • If feasible, use a smaller model or reduce the complexity of the task to require less memory.
  • Certain applications or model versions may require significantly less VRAM and could provide a solution without compromising too much performance.

Summary

Running out of VRAM is a common limitation, especially for demanding AI tasks. On Windows, shared memory fallback may alleviate the issue by offloading to system RAM, although this can impact performance. Disabling this fallback can stabilize performance, but it may lead to crashes if VRAM is exceeded. Linux users will need to rely on VRAM optimization techniques since shared memory fallback is not supported.

For more information, see NVIDIA’s official documentation: NVIDIA System Memory Fallback Guide

AllTalk Start-up Issues

🟦 Dealing with a TTS engine not loading e.g. model file is missing etc.

Explanation and Fix

If you have an issue with one of the TTS engines failing to start-up because Coqui TTS (XTTS, VITS) is damaged OR Parler TTS is damaged, you can download the base tts_engine.json and save it over your current tts_engine.json file to get back to factory. It can be downloaded from here using the Download Raw file (arrow pointing down over an inbox icon on the top right of the page) and saving it over the top of your alltalk_tts/system/tts_engines/tts_engine.json file.

🟦 ModuleNotFoundError: No module named 'XXXXXXX'

🟦 PortAudio Installation on Linux

Explanation and Fix

Method 1: Check Library Files

Run this command to check if PortAudio libraries exist on your system:

ls /usr/lib/x86_64-linux-gnu/libportaudio*

Expected output should show these files:

/usr/lib/x86_64-linux-gnu/libportaudio.so
/usr/lib/x86_64-linux-gnu/libportaudio.so.2
/usr/lib/x86_64-linux-gnu/libportaudio.so.2.0.0

Method 2: Check Package Configuration

Alternatively, you can verify PortAudio installation using pkg-config:

pkg-config --libs portaudio-2.0

Expected output:

-L/usr/lib/x86_64-linux-gnu -lportaudio

Installing/Reinstalling PortAudio

If the above checks fail, you can perform a complete reinstallation:

# Update package list
sudo apt-get update

# Remove existing PortAudio installation
sudo apt-get remove --purge portaudio19-dev

# Install PortAudio and related packages
sudo apt-get install portaudio19-dev python3-pyaudio
sudo apt-get install libasound2-dev

Verifying Python Environment Setup

After installing system packages, ensure PortAudio works in your Python environment:

  1. Activate the AllTalk environment:

    ./start_environment.sh

  2. Check if sounddevice is installed:

    pip show sounddevice

  3. If sounddevice is not installed, install it:

    • Restart your computer

  8. Check for Recent Updates: If the issue started after a recent update, consider if any security patches might be affecting local connections. For example, there have been recent concerns about the "0-day flaw" in browsers: 18-year-old security flaw in Firefox and Chrome exploited in attacks

Note:

If the issue persists after trying these steps, it may be worth checking for any system-wide network issues or consulting with a network administrator if you're on a managed network.

🟦 [Errno 10048] error while attempting to bind on address ('0.0.0.0', 7851): only one usage of each socket address (protocol/network address/port) is normally permitted

Explanation and Troubleshooting Steps

This error indicates that something is already running on the port number specified OR for some reason multiple AllTalk instances of the tts_engine.py is running and a new one is attempting to start up on the same port number.

Error Message:

[Errno 10048] error while attempting to bind on address ('0.0.0.0', 7851): only one usage of each socket address (protocol/network address/port) is normally permitted

Explanation:

This error indicates that port 7851 is already in use by another process. In networking, only one application can bind to a specific port at a time. This is a common issue when:

  • A previous instance of AllTalk didn't shut down properly
  • Another application is using the same port
  • Multiple instances of AllTalk are trying to run simultaneously

Potential Causes:

  1. Zombie AllTalk process still running in the background
  2. Another application is using port 7851
  3. Multiple instances of tts_engine.py were started
  4. Previous crash or improper shutdown left the port in a bound state

Troubleshooting Steps:

Option 1: Change the Port Number

  1. Open the Gradio interface
  2. Navigate to the settings section
  3. Look for the port configuration option
  4. Change the port number to an unused port (e.g., 7852)
  5. Alternatively, edit the confignew.json file directly and modify the port number
  6. Restart AllTalk

Option 2: Kill Existing Processes

Windows:
  1. Open Task Manager (Ctrl + Shift + Esc)
  2. Go to the "Details" or "Processes" tab
  3. Look for Python processes
  4. Right-click and select "Properties" to verify if it's AllTalk-related
  5. If confirmed, right-click and select "End Task"
Linux:
  1. Open terminal
  2. Find processes using the port: 
    sudo lsof -i :7851
  3. Find Python processes that might be AllTalk: 
    ps aux | grep python
  4. Kill the specific process: 
    kill <process_id>
    or force kill if necessary: 
    kill -9 <process_id>

Option 3: Check Port Usage

  1. Check what's using the port:
    • Windows: netstat -ano | findstr :7851
    • Linux: netstat -tulpn | grep :7851
  2. Identify the process ID (PID)
  3. Verify if it's AllTalk-related
  4. Close the application using that port

Prevention:

  1. Always close AllTalk properly through the interface
  2. Check for running instances before starting a new one
  3. Consider setting up a different default port in the configuration
  4. Implement a startup script that checks for existing instances

🟦 UserWarning: Torch was not compiled with flash attention

Explanation

You may encounter the following warning when running PyTorch-based applications:

UserWarning: 1Torch was not compiled with flash attention.

Explanation:

This warning is related to a feature called "Flash Attention" in PyTorch, which is an optimization for certain types of attention mechanisms in neural networks.

Key points to understand:

  1. This is a generic PyTorch issue and not specific to AllTalk or any particular application.
  2. Flash Attention is not currently supported on Windows systems.
  3. On Windows, this message is a notification rather than an error.

Impact:

  • For Windows users: This warning can be safely ignored. It does not affect the functionality of your PyTorch-based applications.
  • For non-Windows users: If you're seeing this on a non-Windows system where Flash Attention should be supported, you might want to investigate further.

Why it occurs:

PyTorch checks if it was compiled with Flash Attention support. On Windows, where this feature is not available, the check always returns false, resulting in this warning.

Resolution:

For Windows users:

  • No action is required. You can safely ignore this warning.
  • If you want to suppress the warning, you can use Python's warning filters, but this is generally unnecessary.

For non-Windows users seeing this unexpectedly:

  • Ensure you have the latest version of PyTorch installed.
  • Check if your CUDA installation (if applicable) is up to date and compatible with your PyTorch version.

Additional Information:

This issue has been widely discussed in the PyTorch community. For more details, you can refer to the following GitHub issue: PyTorch Issue #108175

Recommendation:

Unless you specifically need Flash Attention for your work (which is rare for most users), you can continue using PyTorch as normal. This warning does not indicate a problem with your setup or code on Windows systems.

🟦 IMPORTANT: You are using gradio version 4.32.2, however version 5.x.x is available, please upgrade.

Explanation and Troubleshooting Steps

Gradio's developers just like telling everyone to upgrade to their latest version. I cant stop the messages appearing and I have as yet not tested later versions of Gradio, the messages are safe to ignore.

🟦 FutureWarning: You are using torch.load with weights_only=False.....etc

Explanation

Explanation:

PyTorch whom make Torch have included this message with Torch version 2.4.x to state that some time in the future, they will be removing a feature from Torch. At this stage in time, it is nothing more than a warning note to anyone whom develops things to work with Torch. Annoying as the message is, its just a warning message and I cannot filter it out, well, I can, but it would filter out other possible Torch errors that may actually mean something at this point in time.

I am not the developer of the Coqui TTS engine and I know that the developer is currently working on updating the Coqui TTS engine and so assumedly a change will be made in future that will clear up this message.

This error if safe to ignore at this time assuming you are using the XTTS models supplied by AllTalk and not using someone else's model that (I guess) they could have potentially done something with, though this is highly unlikely as I've never seen any other persons XTTS model being shared, so I only mention this as an FYI.

Example error message:

FutureWarning: You are using torch.load with weights_only=False (the current default value), which uses the default pickle module implicitly. It is possible to construct malicious pickle data which will execute arbitrary code during unpickling (See https://github.com/pytorch/pytorch/blob/main/SECURITY.md#untrusted-models for more details). In a future release, the default value for weights_only will be flipped to True. This limits the functions that could be executed during unpickling. Arbitrary objects will no longer be allowed to be loaded via this mode unless they are explicitly allowlisted by the user via torch.serialization.add_safe_globals. We recommend you start setting weights_only=True for any use case where you don't have full control of the loaded file. Please open an issue on GitHub for any issues related to this experimental feature.

🟦 UserWarning: huggingface_hub cache-system uses symlinks by default to efficiently store duplicated files.....etc

Explanation

Explanation:

This is typically only seen on Windows machines and is safe to ignore. This is just a warning from Huggingface's cache system that downloads may be slightly degraded as it doesn't have full Administrator access to your user accounts temp cache area https://huggingface.co/docs/huggingface_hub/v0.25.2/guides/manage-cache#limitations and it in no way impacts AllTalk.

UserWarning: `huggingface_hub` cache-system uses symlinks by default to efficiently store duplicated files but your 
machine does not support them in C:\Users\useraccount\.cache\huggingface\hub\models--Systran--faster-whisper-large-v2. 
Caching files will still work but in a degraded version that might require more space on your disk. This warning can 
be disabled by setting the `HF_HUB_DISABLE_SYMLINKS_WARNING` environment variable. For more details, see 
https://huggingface.co/docs/huggingface_hub/how-to-cache#limitations.

To support symlinks on Windows, you either need to activate Developer Mode or to run Python as an administrator. In 
order to activate developer mode, see this article: https://docs.microsoft.com/en-us/windows/apps/get-started/enable

  warnings.warn(message)

🟦 Error: mkl-service + Intel(R) MKL: MKL_THREADING_LAYER=INTEL is incompatible with {library-name-here} library

Explanation and Fix

This error may arise due to incompatibility between Intel’s MKL threading layer (MKL_THREADING_LAYER=INTEL) and certain libraries, such as libgomp-a34b3233.so.1, used by the Python environment. It often appears with messages similar to:

Error: mkl-service + Intel(R) MKL: MKL_THREADING_LAYER=INTEL is incompatible with libgomp-a34b3233.so.1 library.
Try to import numpy first or set the threading layer accordingly. Set MKL_SERVICE_FORCE_INTEL to force it.

In addition, it may be accompanied by warnings during the AllTalk startup sequence:

[AllTalk Startup] Warning TTS Subprocess has NOT started up yet, Will keep trying for 120 seconds maximum. Please wait.
[AllTalk Startup] Startup timed out. Full help available here https://github.com/erew123/alltalk_tts#-help-with-problems

This error may occur due to a version mismatch between PyTorch and DeepSpeed or an environmental setting conflict that prevents AllTalk from initializing. When this happens, AllTalk may repeatedly attempt to start without success, leading to a startup timeout.

To resolve this issue:

  1. Set the MKL Threading Layer: Set the environment variable MKL_THREADING_LAYER=GNU before starting AllTalk. This can resolve compatibility issues between MKL and other libraries. For example: 
    export MKL_THREADING_LAYER=GNU
./start_alltalk.sh
    Or simply starting AllTalk as 
    MKL_THREADING_LAYER=GNU ./start_alltalk.sh

🟧 SillyTavern Error: HTTP 404: Failed to fetch audio data

Explanation and Resolution

When using SillyTavern with AllTalk, you may encounter the following error:

HTTP 404: Failed to fetch audio data

Explanation:

This error typically occurs due to a version mismatch between the AllTalk extension in SillyTavern and the version of AllTalk you're running.

Key points to understand:

  1. SillyTavern currently comes bundled with the AllTalk version 1 extension by default.
  2. If you're running AllTalk version 2, the bundled extension will be incompatible, leading to this error.
  3. The extension needs to be manually updated to match your AllTalk version.

Resolution:

To resolve this issue, you need to update the AllTalk extension in SillyTavern to match your AllTalk version. Here's what to do:

  1. Determine which version of AllTalk you're running (likely version 2 if you're seeing this error).
  2. Follow the instructions provided in the AllTalk wiki to update the SillyTavern extension.

Detailed instructions for updating the extension can be found here: SillyTavern Extension Update Instructions

Important Notes:

  • Always ensure that your SillyTavern AllTalk extension version matches the version of AllTalk you're running.
  • Keep an eye on both AllTalk and SillyTavern updates, as you may need to manually update the extension after upgrading either component.

Future Updates:

In the future, the extension will be updated in SillyTavern. Until then, manual updates are necessary to ensure compatibility.

Recommendation:

Before reporting issues with AllTalk integration in SillyTavern, always verify that you have the correct extension version installed. If you're unsure, refer to the AllTalk documentation or the SillyTavern Extension wiki page linked above.

🟧 SillyTavern: How To Reset AllTalk in SillyTavern/Settings Not Updating/Issue with IP/etc

Explanation and Resolution

If you are encountering issues and wish to reset the AllTalk settings in SillyTavern, you can do so with the following process.

Resolution:

  1. Browse to your \SillyTavern\data\default-user\ folder and make a backup copy of the settings.json. This is to be used if you make a mistake and need to recover the file.
  2. Open the settings.json file in notepad or whatever text editor software you use.
  3. Search the file for alltalk and you should find a section called "tts": { that has an AllTalk section within it.
  4. You are going to select from "AllTalk": { all the way down to its closing bracket }, and delete that section e.g.

image

  1. Once you have deleted that section, save the file and re-start SillTavern.
  2. Set up your AllTalk settings again in SillyTavern, as if it was a brand new installation.
  3. [Optional] If you have accidentally damaged the format of the file, you can recover from the copy you made earlier and try again.

TTS Generation Issues

🟩 XTTS/Coqui TTS - Streaming - ERROR:Exception in ASGI application

Explanation and Fix

You can get an error message similar to the one shown below when you are using the Coqui TTS engine, with XTTS and you are trying to stream audio. This will therefore affect Kobold as it currently only uses streaming. It will affect any other application where you are using streaming with XTTS.

This issue is caused by the fact that the Coqui TTS engine (at time of writing) requires transformers version 4.42.4 to support streaming. Other TTS engines or software like Text-generation-webui may install a different version of transformers. Parler for example, installs version 4.43.X and you are given the option when installing AllTalk to downgrade transformers. The fix is listed down below the example error message.

    +------------------------------------

To fix this:

  1. Ensure you're using the correct Python environment:
    • On Windows: Run start_environment.bat
    • On Linux: Run ./start_environment.sh

Obviously if you are running within Text-generation-webui's Python environment (not installing AllTalk as a Standalone install) you would use Text-generation-webui's files to start its Python environment e.g. cmd_windows.bat. If you don't feel you quite understand Python environments, please go read Understanding Python Environments which should help explain things.

  1. Install transformers version 4.42.4: 
    pip install transformers==4.42.4

When this installs, you will see a message showing the version of transformers it is replacing, Successfully uninstalled transformers-X.XX.X, so you may want to make a note of that in case you want to revert back at a later stage. The message would look something like:

```
Installing collected packages: transformers
  Attempting uninstall: transformers
    Found existing installation: transformers 4.43.3
    Uninstalling transformers-4.43.3:
      Successfully uninstalled transformers-4.43.3
```

You WILL get a message about PIP not being able to confirm all version are correct and it may say there COULD be issues with other packages (the PIP dependency resolver will report this, typically in RED text). This should get you back to working with XTTS, though it may cause issues with Parler TTS as Parler's dev's have not tested Parler with an earlier version of transformers (though it appears to be working absolutely fine). I cannot speak as to any other software it may impact e.g. it may impact Text-generation-webui's model loaders (possibly). You can always upgrade transformers with the above method and changing the version installed.

If for any reason you have an issue where AllTalk is failing to load because it cant find the model file or something like that, you can always reset the model it is trying to load, to something like Piper, which should at least allow AllTalk to load in. Instructions to do this are below on Dealing with a TTS engine not loading e.g. model file is missing etc..

🟩 Warning: The text length exceeds the character limit of XXX for language 'XX'

Explanation and Potential Solutions

This warning appears when using Coqui TTS models and indicates that the input text exceeds the character limit for the specified language. The warning typically looks like this:

Warning: The text length exceeds the character limit of XXX for language 'XX', this might cause truncated audio.

Explanation:

  • Coqui TTS models have predefined character limits for each supported language.
  • These limits are set in the tokenizer and are based on the model's training data.
  • Exceeding this limit may result in degraded audio quality or truncation of the generated speech.

Important Notes:

  1. This is a warning, not an error. The system will still attempt to process the text, but the results may not be optimal.
  2. The actual impact on audio quality can vary depending on the specific model and the extent to which the limit is exceeded.

Potential Solutions:

  1. Reduce Input Text: The most straightforward solution is to shorten your input text to fall within the character limit for the chosen language.

  2. Split Text: For longer passages, consider splitting the text into smaller segments that fall within the limit and process them separately.

  3. Adjust Tokenizer Limits: While it's possible to modify the character limits in the tokenizer, this won't actually improve the model's performance or remove the underlying limitation. It will only suppress the warning.

    To adjust the limit (not recommended):

    tokenizer = TTSTokenizer.from_pretrained(model_name)
tokenizer.max_input_tokens = new_limit  # e.g., 1000
tokenizer.save_pretrained(output_dir)

    Note: This modification only affects the warning threshold, not the model's actual capabilities.
