🐛 Bug

I am trying to run llava with mlc-llm. On both a linux server machine and a local MacOS, I encountered this error:

(run export RUST_BACKTRACE=full before running the inference program.)

To Reproduce

Steps to reproduce the behavior:

  1. Installing packages:

On MacOS:

pip install mlc_ai_cpu-0.17.1-cp39-cp39-macosx_13_0_arm64.whl
pip install mlc_llm_cpu-0.17.1-cp39-cp39-macosx_13_0_arm64.whl

On Linux:

pip install mlc_ai_cu123-0.17.2-cp310-cp310-manylinux_2_28_x86_64.whl 
pip install mlc_llm_cu123-0.17.2-cp310-cp310-manylinux_2_28_x86_64.whl
  1. convert and compile model
mlc_llm convert_weight --model-type llava ../hub/llava-hf/llava-1.5-7b-hf --quantization q4f16_1 -o llava-1.5-7b-hf-mlc
mlc_llm gen_config ../hub/llava-hf/llava-1.5-7b-hf --quantization q4f16_1  --conv-template llava -o llava-1.5-7b-hf-mlc
mlc_llm compile llava-1.5-7b-hf-mlc/mlc-chat-config.json --device cuda -o llava-1.5-7b-hf-mlc/llava-1.5-7b-q4f16_1-cuda.so # or for macos
  1. run the model 
    
from mlc_llm import MLCEngine
import PIL.Image
from io import BytesIO
import base64

model = "/path/to/llava-1.5-7b-hf-mlc" model_lib = "/path/to/llava-1.5-7b-hf-mlc/llava-1.5-7b-q4f16_1-cuda.so" image_path = "/path/to/image.jpg" engine = MLCEngine(model=model, model_lib=model_lib)

img = PIL.Image.open(image_path) img_resized = img.resize((336, 336))

img_byte_arr = BytesIO() img_resized.save(img_byte_arr, format="JPEG") img_byte_arr = img_byte_arr.getvalue()

new_url = ( f"data:image/jpeg;base64,{base64.b64encode(img_byte_arr).decode('utf-8')}" )

for response in engine.chat.completions.create( messages=[{ "role": "user", "content": [ { "type": "image_url", "image_url": new_url, }, { "type": "text", "text": "What is shown in this image?", }, ], }], model=model, stream=True, ): for choice in response.choices: print(choice.delta.content, end="", flush=True)

engine.terminate()

HI @HoiM, could you try to install the latest nightly packages of mlc-llm and mlc-ai? We fixed the issue last week in https://github.com/mlc-ai/mlc-llm/commit/347407375474e99dcb14647299853c7e1263c008, which is not yet included in a stable release. You can find the nightly package installation instructions at https://llm.mlc.ai/docs/install/mlc_llm.html.

On my MacOS, reinstalling the following two wheels solved the problem.

pip install mlc_ai_nightly_cpu-0.18.dev249-cp39-cp39-macosx_13_0_arm64.whl
pip install mlc_llm_nightly_cpu-0.18.dev71-cp39-cp39-macosx_13_0_arm64.whl

THX!
