Error installing: salesforce-lavis 1.0.2 depends on decord

[shakedzy]

I'm trying to pip install lavis, but keeps getting this:

ERROR: Cannot install salesforce-lavis==1.0.0 and salesforce-lavis==1.0.2 because these package versions have conflicting dependencies.

The conflict is caused by:
    salesforce-lavis 1.0.2 depends on decord
    salesforce-lavis 1.0.0 depends on decord

When trying to run pip install decord I get:

ERROR: Could not find a version that satisfies the requirement decord (from versions: none)
ERROR: No matching distribution found for decord

I tried this on new virtual-envs using Python 3.11, 3.10 and 3.8 on an M1 mac.

Hi, @shakedzy I met the same error onM1 Macbook with Python 3.18.16.

I did some search and found that it's because the decord does not support M1 chip. See here: dmlc/decord#225

I am afraid it just does not work to install lavis on M1 chip Macbook

[karvinok]

same here. it depends on decord and not possible to install

Seems like the open issue on decord is from 08/2022, so I guess this isn't getting fixed any time soon..

I'm on Intel, not M1, but it's possible you could try to install from source?

brew install ffmpeg cmake
git clone --recursive https://github.com/dmlc/decord
cd decord
mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
make
cd ../python
python setup.py install

You may need to change some source code as shown here: dmlc/decord#186 (comment)

Hello, for anyone landing here, this is how i temporarily fixed this annoying issue.

I am using python 3.10 on Intel macOS, but it looks like there are no wheels for decord for my python version (up to 3.8).
So, I downloaded the wheel manually (Wheels), I used decord-0.6.0-cp38-cp38-macosx_10_15_x86_64.whl

Then, I tried to pip install decord-0.6.0-cp38-cp38-macosx_10_15_x86_64.whl, but it yielded errors because cp38 means I should have python3.8.

I changed the filename to decord-0.6.0-cp310-cp310-macosx_10_15_x86_64.whl and ran pip install decord-0.6.0-cp310-cp310-macosx_10_15_x86_64.whl, package installed successfully.

Afterwards I ran python3 -m pip install salesforce-lavis and finally I managed to install it.

Note: I tried to install decord from source: no success.

[Andrew-Chen-Wang]

If you install from source, you need to change the source code itself because you likely have an incompatible ffmpeg (v5 instead of v4).

I was able to run the Zoo on ARM 64 Ubuntu Linux / Python 3.9 after doing the following steps. I have not tried anything else yet.

1. Use @devfacet's suggestion with a few modifications of the eva-decord instructions.

• Make sure to clone the repository recursively -- not zip download. There are dependencies on other Git projects.
• Follow the instructions to build.
• Copy the libdecord.so into the decord/python directory.
• Modify python/setup.py replacing 'libdecord.dylib' with 'libdecord.so'
• python3.9 setup.py install --user

Example code:

apt-get update
apt-get install -y build-essential python3-dev python3-setuptools make cmake
apt-get install -y ffmpeg libavcodec-dev libavfilter-dev libavformat-dev libavutil-dev
git clone --recursive https://github.com/georgia-tech-db/eva-decord.git
mkdir eva-decord/build & cd eva-decord/build
cmake .. -DUSE_CUDA=0 -DCMAKE_BUILD_TYPE=Release
make
cp libdecord.so ../python
cd ../python & sed -i 's/dylib/so/g' setup.py
python3.9 setup.py install --user

2. Copy requirements.txt from the Lavis repository tagged 1.0.2 and add the following lines after removing decord.

langcodes
pathy
smart-open
spacy-legacy
spacy-loggers
typer==0.7.*
thinc
huggingface_hub
braceexpand
portalocker
antlr4-python3-runtime==4.9.*
eva-decord

3. Install Lavis using modified requirements
   python3.9 -m pip install salesforce-lavis==1.0.2 --no-deps -r lavisRequirements.txt

I had to make a small change above because it was still breaking on my M1 with Python3.10 because of the version specified for open3d in requirements (open3d==0.13.0). I simply removed the version from it
