Hi, the error message provided is not enough to find out the failure reason. BTW, you can install it with the pre-built packages by the following commands.
pip install -U openmim
mim install mmcv-full

Thank you for your reply. I have tried the method you provided. I also tried using pip install mmcv-full==1.6.2 -f https://download.openmmlab.com/mmcv/dist/cu111/torch1.9/index.html to install mmcv-full which fits my environment.
But while I follow the Official Tutorials to compile mmcv-full with using This command python setup.py build_ext in Anaconda powershell prompt.
It still raise error：
Traceback (most recent call last):
File "setup.py", line 520, in
Anyway, when I using python .dev_scripts/check_installation.py to validate installation, it work! Here is the output: TorchVision: 0.10.0 OpenCV: 4.7.0 MMCV: 1.6.2 MMCV Compiler: MSVC 192930137 MMCV CUDA Compiler: 11.1
However, this file _ext.cp38-win_amd64.pyd is not in the mmcv folder. I knew it had failed to compile.
I hope you can help me solve this problem!
