hi, could you tell me which file that appears the error?

[CN-makers]

in the https://github.com/VectorSpaceLab/Video-XL/blob/main/videoxl/videoxl/model/language_model/llava_llama.py. i think
maybe because https://github.com/VectorSpaceLab/Video-XL/blob/main/videoxl/videoxl/model/__init__.py cite this file?

The current code only supports Qwen as language model, I will update it to adapt other LLM like LLaMA.

Solution 1: Adjust the Import Path

If the issue arises due to an incorrect import statement, you can fix it by modifying the llava_llama.py file.

1. File: Video-XL/videoxl/videoxl/model/language_model/llava_llama.py

2. Import Problem:

   # from longva.model.llava_arch import LlavaMetaModel, LlavaMetaForCausalLM
   from ..llava_arch import LlavaMetaModel, LlavaMetaForCausalLM

Solution 2: Install the longva Module

   Run the following commands:

   git clone https://github.com/EvolvingLMMs-Lab/LongVA.git
   cd LongVA/

2. Install with Dependencies:
   Use the pip command to install the longva module along with its optional training dependencies:

   python -m pip install -e "longva/.[train]"
