I've done the following:

Alternatively, one may also skip the quantization process and directy download the quantized VILA-1.5 checkpoints from here. Take VILA-1.5-13B as an example, after running:

cd tinychat git clone https://huggingface.co/Efficient-Large-Model/VILA1.5-13b-AWQ One may run:

python vlm_demo_new.py \
    --model-path VILA1.5-13b-AWQ \
    --quant-path VILA1.5-13b-AWQ/llm \ 
    --precision W4A16 \
    --image-file /PATH/TO/INPUT/IMAGE \

from the docs. Then for some reason the model_path looks for the non-quantized safetensors file:

(base) ~/llm-awq/tinychat$ CUDA_VISIBLE_DEVICES=0 python vlm_demo_new.py --model-path VILA1.5-13b-AWQ --quant-path VILA1.5-13b-AWQ/llm --precision W4A16 --image-file ../../docs-fuji-red.jpg

@kousun12, There may be issues with your environment. You can use the following dockerfile to setup an environment with llm-awq and VILA.

[kousun12]

a dockerfile is very helpful - thanks for that. i will give this a try

[kousun12]

I'm also running on H100s and have seen issues in the log console around TORCH_CUDA_ARCH_LIST -- Should I be setting that to 9.0?

[hkunzhe]

I think so.

[NigelNelson]

I'm also running on H100s and have seen issues in the log console around TORCH_CUDA_ARCH_LIST -- Should I be setting that to 9.0? Should be setting it as:

TORCH_CUDA_ARCH_LIST="9.0+PTX"

[cktlco]

Based on the OP's suggestion, I was able to resolve exactly the same issue by specifying the vila-1.5-13b-w4-g128-awq-v2.pt file location (not just the llm/ directory) directly in the --quant-path param. After this, the demo worked as expected.

python vlm_demo_new.py --model-path ../VILA1.5-13b-AWQ --quant-path ../VILA1.5-13b-AWQ/llm/vila-1.5-13b-w4-g128-awq-v2.pt --precision W4A16 --image-file ../VILA/demo_images/av.png

[rahulthakur319]

Thanks @cktlco . I also stumbled on the same issue. Using the exact file location path in --quant-path, I was able to get a bit further. However then this issue came up.

GPU: RTX A6000

python vlm_demo_new.py --model-path /root/llm-awq/tinychat/VILA1.5-13b-AWQ --quant-path /root/llm-awq/tinychat/VILA1.5-13b-AWQ/llm/vila-1.5-13b-w4-g128-awq-v2.pt --precision W4A16 --image-file /root/VILA/demo_images/av.png
