Supports LLAMA2, Mistral, Mixtral (unverified), Gemma and StarCoder2 models. The nemo.export.tensorrt_llm alias was removed to avoid initializing TRT-LLM when importing anything from nemo.export. Signed-off-by: Alexey Panteleev * Fixed some CodeQL warnings. Signed-off-by: Alexey Panteleev * Apply isort and black reformatting Signed-off-by: apanteleev * Removed empty files. Signed-off-by: Alexey Panteleev * Apply isort and black reformatting Signed-off-by: apanteleev * Updated the integration for vLLM 0.5.0. Signed-off-by: Alexey Panteleev * Updated the vLLM deployment interface to use max_output_len instead of max_output_token. Signed-off-by: Alexey Panteleev * Apply isort and black reformatting Signed-off-by: apanteleev * Moved the Exporter class to nemo/export and renamed its file to vllm_exporter.py, to be more similar to TRT-LLM. Signed-off-by: Alexey Panteleev * Apply isort and black reformatting Signed-off-by: apanteleev * Implemented vLLM support in the export tests, added functional testing, implemented forward evaluation on vLLM without Triton. Signed-off-by: Alexey Panteleev * Apply isort and black reformatting Signed-off-by: apanteleev * Moved the vLLM deployment functionality to the common deploy_triton.py script. Signed-off-by: Alexey Panteleev * Apply isort and black reformatting Signed-off-by: apanteleev * Fixed the CodeQL discovered issues. Signed-off-by: Alexey Panteleev * Apply isort and black reformatting Signed-off-by: apanteleev * Fixed one more return of a wrong dimensionality... Signed-off-by: Alexey Panteleev * More wrong dimensionality returns.

Alternatively, a single DGX A100 node with 8x 40GB GPUs can be used for the same purpose. +For bigger models like Llama2 70B, you may need to use one or more DGX H100 nodes with 8x 80GB GPUs each. + +The example is a modified version of the `SFT with Llama 2 playbook `_. +Please refer to the playbook for more details on setting up a BF16 NeMo model and the ``databricks-dolly-15k`` instruction dataset. -`Integer Quantization for Deep Learning Inference: Principles and Empirical Evaluation, 2020 `_ +First we will run the SFT example command from the playbook as-is to train a Llama2 7B SFT model for 100 steps. +Make sure to change ``trainer.max_steps=50`` to ``trainer.max_steps=100`` for the ``examples/nlp/language_modeling/tuning/megatron_gpt_finetuning.py`` script. +This will take ~2 hours to produce a model checkpoint with validation loss approximately ``1.15`` that we will use for PTQ and QAT next. -`FP8 Formats for Deep Learning, 2022 `_ +For Quantization, we use a modified version of the sft script and config file which includes the quantization and TensorRT-LLM export support. +Along with the new parameters, make sure to pass the same parameters you passed for SFT training except the model restore path will be the SFT output ``.nemo`` file. +The below example command will perform PTQ on the SFT model checkpoint followed by SFT again (QAT) which can then be exported for TensorRT-LLM inference.

vLLM export functionality from the common deployment script into deploy_vllm_triton.py. Signed-off-by: Alexey Panteleev * Fixed vocab_size for LLAMA3. Signed-off-by: Alexey Panteleev * Export test: fixed deployment testing w/o Megatron, made functional tests optional, added --gpu_memory_utilization. Signed-off-by: Alexey Panteleev * Apply isort and black reformatting Signed-off-by: apanteleev * Addressing review and CodeQL comments.

SSMs offer advantages such as linear time complexity relative to sequence length and a constant cache size for inference. These features enable the processing of longer sequences and higher throughput. Despite these benefits, SSMs alone may fall short compared to transformers on tasks that demand strong copying or in-context learning capabilities. + +To harness the strengths of both approaches, SSM-Hybrid models incorporate MLP, Transformer, and SSM blocks in their architecture. As highlighted in `a study by NVIDIA `__, these hybrid models outperform traditional transformers of the same size by achieving faster inference times due to the inclusion of SSM blocks. Based on experimental results, Mamba2-Hybrid models not only surpass transformer baselines in performance but also benefit from increased computational efficiency. + +The Mamba2 models discussed in the `Transformers are SSMs `__ paper are available in five different sizes: 130 million, 370 million, 780 million, 1.3 billion, and 2.7 billion parameters. The Mamba2-Hybrid models, along with their Mamba2 baseline as released by `NVIDIA `__, are provided in an 8 billion parameter size. + +`Low-Rank Adaptation (LoRA) `__ has emerged as a popular Parameter Efficient Fine-Tuning (PEFT) technique that tunes a very small number of additional parameters as compared to full fine-tuning, thereby reducing the compute required. LoRA tuning can be applied to the linear layers in the Transformer and MLP blocks for the Mamba2-Hybrid models. + +`NVIDIA NeMo +Framework `__ provides tools to perform Fine-tuning on Mamba2 and Mamba2-Hybrid to fit your use case. + +Requirements +------------- + +In order to proceed, ensure that you have met the following requirements: + +* Full Fine-Tuning System Configuration + * Small models (130m, 370m, 780m) + * Access to at least 1 NVIDIA GPU with a cumulative memory of at least 40GB, for example: 1 x A6000-40GB. + + * Mid-size models (1.3b, 2.7b) + * Access to at least 1 NVIDIA GPU with a cumulative memory of at least 80GB, for example: 1 x H100-80GB or 1 x A100-80GB. + + * Large models (8b) + * Access to at least 2 NVIDIA GPUs with a cumulative memory of at least 80GB, for example: 2 x H100-80GB or 2 x A100-80GB. + +* LoRA Fine-Tuning (Mamba2-Hybrid only) System Configuration + * Access to at least 1 NVIDIA GPU with a cumulative memory of at least 80GB, for example: 1 x H100-80GB or 1 x A100-80GB. + + + +* A Docker-enabled environment, with `NVIDIA Container Runtime `_ installed, which will make the container GPU-aware. + + +* `Authenticate with NVIDIA NGC `_, and download `NGC CLI Tool `_. + + +Step-by-step Guide for Fine-Tuning +---------------------------------- + +Checkpoints from HuggingFace +^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Obtain the desired checkpoint from HuggigFace. + +* `Repository `__ for the Mamba2 models from the `Transformers are SSMs paper `__. +* `Repository `__ for the Mamba2 and Mamba2-Hybrid models by `NVIDIA `__. + + +Convert the Pytorch Checkpoint to a NeMo Checkpoint +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +1.
