MobileVLM

Currently this implementation supports MobileVLM-v1.7 variants.

for more information, please go to Meituan-AutoML/MobileVLM

The implementation is based on llava, and is compatible with llava and mobileVLM. The usage is basically same as llava.

Usage

Build with cmake or run make llava-cli to build it.

After building, run: ./llava-cli to see the usage. For example:

./llava-cli -m MobileVLM-1.7B/ggml-model-q4_k.gguf \
    --mmproj MobileVLM-1.7B/mmproj-model-f16.gguf \
    --image path/to/an/image.jpg \
    -p "A chat between a curious user and an artificial intelligence assistant. The assistant gives helpful, detailed, and polite answers to the user's questions. USER: <image>\nWho is the author of this book? Answer the question using a single word or phrase. ASSISTANT:"

Model conversion

  • Clone mobileVLM-1.7B and clip-vit-large-patch14-336 locally:
git clone https://huggingface.co/mtgv/MobileVLM-1.7B

git clone https://huggingface.co/openai/clip-vit-large-patch14-336
  1. Use llava-surgery.py to split the LLaVA model to LLaMA and multimodel projector constituents:
python ./examples/llava/llava-surgery.py -m path/to/MobileVLM-1.7B
  1. Use convert-image-encoder-to-gguf.py with --projector-type ldp to convert the LLaVA image encoder to GGUF:
python ./examples/llava/convert-image-encoder-to-gguf \
    -m path/to/clip-vit-large-patch14-336 \
    --llava-projector path/to/MobileVLM-1.7B/llava.projector \
    --output-dir path/to/MobileVLM-1.7B \
    --projector-type ldp
  1. Use convert.py to convert the LLaMA part of LLaVA to GGUF:
python ./convert.py path/to/MobileVLM-1.7B
  1. Use quantize to convert LLaMA part's DataType from fp16 to q4_k
./quantize path/to/MobileVLM-1.7B/ggml-model-f16.gguf path/to/MobileVLM-1.7B/ggml-model-q4_k.gguf q4_k_s

Now both the LLaMA part and the image encoder is in the MobileVLM-1.7B directory.

Minor shortcomings

The n_patch of output in ldp is 1/4 of the input. In order to implement quickly, we uniformly modified clip_n_patches function to a quarter. when counting the time consumption, the calculated time will be 4 times bigger than the real cost.

TODO

  • Support non-CPU backend for the new operators, such as depthwise, hardswish, hardsigmoid

  • Optimize LDP projector performance

    - Optimize the structure definition to avoid unnecessary memory rearrangements, to reduce the use of `ggml_permute_cpy`;
    - Optimize operator implementation (ARM CPU/NVIDIA GPU): such as depthwise conv, hardswish, hardsigmoid, etc.
    
  • run MobileVLM on Jetson Orin

  • Support more model variants, such as MobileVLM-3B.
