 Arguments info:
 - `--repo-id-or-model-path REPO_ID_OR_MODEL_PATH`: argument defining the huggingface repo id for the Vicuna model (e.g. `lmsys/vicuna-7b-v1.5`) to be downloaded, or the path to the huggingface checkpoint folder. It is default to be `'lmsys/vicuna-7b-v1.5'`.
-- `--image-path IMAGE_PATH`: argument defining the image to be infered. It is default to be `demo.jpg`.
+- `--image-path IMAGE_PATH`: argument defining the image to be infered.
 
 > **Note**: When loading the model in 4-bit, BigDL-LLM converts linear layers in the model into INT4 format. In theory, a *X*B model saved in 16-bit will requires approximately 2*X* GB of memory for loading, and ~0.5*X* GB memory for further inference.
