MMCV legacy-install-failure

[deanAirre]

Hello SETR-developers, I hope you have great day,

I have been trying to install the mmcv through pip install mmcv-full==1.2.2 -f https://download.openmmlab.com/mmcv/ although the code ends up failing due to

Building wheel for mmcv-full (setup.py) ... error
  error: subprocess-exited-with-error

  × python setup.py bdist_wheel did not run successfully.
  │ exit code: 1
  ╰─> [390 lines of output]
      Compiling mmcv._ext without CUDA
      C:\Users\irred\miniconda3\envs\open-mmlab\lib\site-packages\setuptools\installer.py:30: SetuptoolsDeprecationWarning: setuptools.installer is deprecated. Requirements should be satisfied by a PEP 517 installer.
        SetuptoolsDeprecationWarning,

Anyone knows what is wrong?
