安装DCNv3时报错NotADirectoryError: [Errno 20] Not a directory: ‘hipconfig‘_[errno 20] not a directory: '/home/zzyuanyi/.local

解决方法：
1、查看报错信息，找到这一条：和这有关的cuda_to_hip_mappings.py
2、然后去修改这个文件：anaconda3/envs/xxx/lib/python3.10/site-packages/torch/utils/hipify/cuda_to_hip_mappings.py
先cd跳入文件夹，再vim进去
3、添加一个NotADirectoryError

try:
    rocm_path = subprocess.check_output(["hipconfig", "--rocmpath"]).decode("utf-8")
except subprocess.CalledProcessError:
    print(f"Warning: hipconfig --rocmpath failed, assuming {rocm_path}")
# 修改这一行， 添加 NotADirectoryError
except (FileNotFoundError, PermissionError, NotADirectoryError ): 
    # Do not print warning. This is okay. This file can also be imported for non-ROCm builds.
    pass
