MiniCPM-V-2_6

MiniCPM-V-2_6

In this directory, you will find examples on how you could apply IPEX-LLM INT4 optimizations on MiniCPM-V-2_6 model on Intel GPUs. For illustration purposes, we utilize openbmb/MiniCPM-V-2_6 as reference MiniCPM-V-2_6 model.

0. Requirements

To run these examples with IPEX-LLM on Intel GPUs, we have some recommended requirements for your machine, please refer to here for more information.

Example: Predict Tokens using chat() API

In the example chat.py, we show a basic use case for a MiniCPM-V-2_6 model to predict the next N tokens using chat() API, with IPEX-LLM INT4 optimizations on Intel GPUs.

1. Install

1.1 Installation on Linux

We suggest using conda to manage environment:

conda create -n llm python=3.11
conda activate llm
# below command will install intel_extension_for_pytorch==2.1.10+xpu as default
pip install --pre --upgrade ipex-llm[xpu] --extra-index-url https://pytorch-extension.intel.com/release-whl/stable/xpu/us/

pip install transformers==4.40.0 trl

1.2 Installation on Windows

We suggest using conda to manage environment:

conda create -n llm python=3.11 libuv
conda activate llm

# below command will install intel_extension_for_pytorch==2.1.10+xpu as default
pip install --pre --upgrade ipex-llm[xpu] --extra-index-url https://pytorch-extension.intel.com/release-whl/stable/xpu/us/

pip install transformers==4.40.0 trl

2. Configures OneAPI environment variables for Linux

Note

Skip this step if you are running on Windows.

This is a required step on Linux for APT or offline installed oneAPI. Skip this step for PIP-installed oneAPI.

source /opt/intel/oneapi/setvars.sh

3. Runtime Configurations

For optimal performance, it is recommended to set several environment variables. Please check out the suggestions based on your device.

3.1 Configurations for Linux

For Intel Arc™ A-Series Graphics and Intel Data Center GPU Flex Series

export USE_XETLA=OFF
export SYCL_PI_LEVEL_ZERO_USE_IMMEDIATE_COMMANDLISTS=1
export SYCL_CACHE_PERSISTENT=1

For Intel Data Center GPU Max Series

export LD_PRELOAD=${LD_PRELOAD}:${CONDA_PREFIX}/lib/libtcmalloc.so
export SYCL_PI_LEVEL_ZERO_USE_IMMEDIATE_COMMANDLISTS=1
export SYCL_CACHE_PERSISTENT=1
export ENABLE_SDP_FUSION=1

Note: Please note that libtcmalloc.so can be installed by conda install -c conda-forge -y gperftools=2.10.

For Intel iGPU

export SYCL_CACHE_PERSISTENT=1
export BIGDL_LLM_XMX_DISABLED=1

3.2 Configurations for Windows

For Intel iGPU

set SYCL_CACHE_PERSISTENT=1
set BIGDL_LLM_XMX_DISABLED=1

For Intel Arc™ A-Series Graphics

set SYCL_CACHE_PERSISTENT=1

Note

For the first time that each model runs on Intel iGPU/Intel Arc™ A300-Series or Pro A60, it may take several minutes to compile.

4. Running examples

• chat without streaming mode:

  python ./chat.py --prompt 'What is in the image?'
  

• chat in streaming mode:

  python ./chat.py --prompt 'What is in the image?' --stream
  

• save model with low-bit optimization (if LOWBIT_MODEL_PATH does not exist)

  python ./chat.py --repo-id-or-model-path REPO_ID_OR_MODEL_PATH --lowbit-path LOWBIT_MODEL_PATH --prompt 'What is in the image?'
  

• chat with saved model with low-bit optimization (if LOWBIT_MODEL_PATH exists):

  python ./chat.py --lowbit-path LOWBIT_MODEL_PATH --prompt 'What is in the image?'
  

Tip

For chatting in streaming mode, it is recommended to set the environment variable PYTHONUNBUFFERED=1.

Arguments info:

• --repo-id-or-model-path REPO_ID_OR_MODEL_PATH: argument defining the huggingface repo id for the MiniCPM-V-2_6 (e.g. openbmb/MiniCPM-V-2_6) to be downloaded, or the path to the huggingface checkpoint folder. It is default to be 'openbmb/MiniCPM-V-2_6'.
• --lowbit-path LOWBIT_MODEL_PATH: argument defining the path to save/load the model with IPEX-LLM low-bit optimization. If it is an empty string, the original pretrained model specified by REPO_ID_OR_MODEL_PATH will be loaded. If it is an existing path, the saved model with low-bit optimization in LOWBIT_MODEL_PATH will be loaded. If it is a non-existing path, the original pretrained model specified by REPO_ID_OR_MODEL_PATH will be loaded, and the optimized low-bit model will be saved into LOWBIT_MODEL_PATH. It is default to be '', i.e. an empty string.
• --image-url-or-path IMAGE_URL_OR_PATH: argument defining the image to be infered. It is default to be 'http://farm6.staticflickr.com/5268/5602445367_3504763978_z.jpg'.
• --prompt PROMPT: argument defining the prompt to be infered (with integrated prompt format for chat). It is default to be 'What is in the image?'.
• --stream: flag to chat in streaming mode
