LLaVA

In this directory, you will find examples on how you could use IPEX-LLM optimize_model API on LLaVA models on Intel GPUs. For illustration purposes, we utilize the liuhaotian/llava-v1.5-7b as a reference LLaVA 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: Multi-turn chat centered around an image using generate() API

In the example generate.py, we show a basic use case for a LLaVA model to start a multi-turn chat centered around an image using generate() 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 einops # install dependencies required by llava
pip install transformers==4.36.2

git clone https://github.com/haotian-liu/LLaVA.git # clone the llava libary
cp generate.py ./LLaVA/ # copy our example to the LLaVA folder
cd LLaVA # change the working directory to the LLaVA folder
git checkout tags/v1.2.0 -b 1.2.0 # Get the branch which is compatible with transformers 4.36

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 einops # install dependencies required by llava
pip install transformers==4.36.2

git clone https://github.com/haotian-liu/LLaVA.git # clone the llava libary
copy generate.py .\LLaVA\ # copy our example to the LLaVA folder
cd LLaVA # change the working directory to the LLaVA folder
git checkout tags/v1.2.0 -b 1.2.0 # Get the branch which is compatible with transformers 4.36

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

python ./generate.py --image-path-or-url 'https://llava-vl.github.io/static/images/monalisa.jpg'

In the example, several arguments can be passed to satisfy your requirements:

• --repo-id-or-model-path REPO_ID_OR_MODEL_PATH: argument defining the huggingface repo id for the LLaVA model (e.g. liuhaotian/llava-v1.5-7b to be downloaded, or the path to the huggingface checkpoint folder. It is default to be 'liuhaotian/llava-v1.5-7b'.
• --image-path-or-url IMAGE_PATH_OR_URL: argument defining the input image that the chat will focus on. It is required.
• --n-predict N_PREDICT: argument defining the max number of tokens to predict. It is default to be 512.

If you encounter some network error (which means your machine is unable to access huggingface.co) when running this example, refer to Trouble Shooting section.

Sample Output

liuhaotian/llava-v1.5-7b

USER: Do you know who drew this painting?
ASSISTANT: Yes, the painting is a portrait of a woman by Leonardo da Vinci. It's a famous artwork known as the "Mona Lisa."
USER: Can you describe this painting?
ASSISTANT: The painting features a well-detailed portrait of a woman, painted in oil on a canvas. The woman appears to be a young woman staring straight ahead in a direct gaze towards the viewer. The woman's facial features are rendered sharply in the brush strokes, giving her a lifelike, yet enigmatic expression.
The background of the image mainly showcases the woman's face, with some hills visible in the lower part of the painting. The artist employs a wide range of shades, evoking a sense of depth and realism in the subject matter. The technique used in this portrait sets it apart from other artworks during the Renaissance period, making it a notable piece in art history.

The sample input image is:

5 Trouble shooting

5.1 SSLError

If you encounter the following output, it means your machine has some trouble accessing huggingface.co.

requests.exceptions.SSLError: (MaxRetryError("HTTPSConnectionPool(host='huggingface.co', port=443): Max retries exceeded with url: /openai/clip-vit-large-patch14-336/resolve/main/config.json (Caused by SSLError(SSLZeroReturnError(6, 'TLS/SSL connection has been closed (EOF) (_ssl.c:1129)')))"),

You can resolve this problem with the following steps:

1. Download https://huggingface.co/openai/clip-vit-large-patch14-336 on some machine that can access huggingface.co, and put it in huggingface's local cache (default to be ~/.cache/huggingface/hub) on the machine that you are going to run this example.
2. Set the environment variable (export TRANSFORMERS_OFFLINE=1) before you run the example.
