OPEA/Qwen2-VL-72B-Instruct-int2-sym-inc

Model Details

This model is an INT2 model with group_size 128 and symmetric quantization of Qwen/Qwen2-VL-72B-Instruct generated by intel/auto-round. Load the model with revision="eac2fb6" to use AutoGPTQ format.

How To Use

Requirements

The code of Qwen2-VL has been in the latest Hugging face transformers and we advise you to build from source with command pip install git+https://github.com/huggingface/transformers, or you might encounter the following error:

KeyError: 'qwen2_vl'

##INT2:
## The image shows a woman and a dog sitting on a sandy beach near the ocean. The woman is wearing a plaid shirt and has long hair, while the dog is wearing a harness with a colorful pattern. They are both sitting facing each other, with the woman holding the dog's paw in her hand. The background features the ocean waves and the sun setting or rising, creating a warm and serene atmosphere. The overall scene conveys a sense of companionship and relaxation between the woman and her dog.

##BF16:
## The image depicts a serene beach scene at sunset. A person is sitting on the sand, facing the ocean, with their back to the camera. They are wearing a plaid shirt and shorts. Next to them, a large dog, possibly a Labrador Retriever, is sitting upright, facing the person. The dog is wearing a harness. The sun is setting in the background, casting a warm glow over the entire scene, creating a peaceful and tranquil atmosphere. The waves gently lap at the shore, adding to the calm ambiance.

Evaluation the model

pip3 install git+https://github.com/open-compass/VLMEvalKit.git@7de2dcb. The evaluation process may encounter errors that require changing model backend or evaluation code. Detailed instructions will be provided in a future update.

Generate the model

Here is the sample command to reproduce the model.

pip install auto-round
auto-round-mllm
--model Qwen/Qwen2-VL-72B-Instruct \
--device 0,1 \
--group_size 64 \
--bits 2 \
--iters 2000 \
--nsample 1024 \
--low_gpu_mem_usage \
--seqlen 2048 \
--model_dtype "float16" \
--format 'auto_gptq,auto_round' \
--output_dir "./tmp_autoround"

Ethical Considerations and Limitations

The model can produce factually incorrect output, and should not be relied on to produce factually accurate information. Because of the limitations of the pretrained model and the finetuning datasets, it is possible that this model could generate lewd, biased or otherwise offensive outputs.

Therefore, before deploying any applications of the model, developers should perform safety testing.

Caveats and Recommendations

Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model.
