 ***A***:This is because the program launched through MPI reads `OMP_NUM_THREADS=1`, which cannot correctly retrieve the appropriate value from the environment. It is necessary to manually set the value of `OMP_NUM_THREADS` based on the actual situation.
 
 - ***Q***: Why do I still encounter errors when converting already supported models?  
-***A***: Try downgrading `transformer` to an appropriate version, such as the version specified in the `requirements.txt`. This is because different versions of Transformer may change the names of certain variables.

 - ***Q***: I encountered an error saying that `mkl.h` could not be found during compilation. What should I do?  
 ***A***: Please check if the `onednn` folder under `3rdparty/` is empty. If it is, delete it and rerun CMake. Additionally, if the `3rdparty/mkl/` folder contains only a `local` directory, move all contents from `mkl/local/*` to `mkl/`.

 ***答***:这是因为通过 MPI 启动的程序读取的是 `OMP_NUM_THREADS=1`，无法从环境中正确获取相应的值。有必要根据实际情况手动设置 `OMP_NUM_THREADS` 的值。

 ***答***：请检查 `3rdparty/` 目录下的 `onednn` 文件夹是否为空。如果为空，请将其删除并重新运行 CMake。此外，如果 `3rdparty/mkl/` 文件夹内仅包含 `local` 目录，请将 `mkl/local/*` 中的所有内容移动到 `mkl/` 目录下。
