[Bug] Building wheels extremely slow on Google Colab (cu121, torch2.2.1)

[odusseys]

Prerequisite

• I have searched Issues and Discussions but cannot get the expected help.
• The bug has not been fixed in the latest version(https://github.com/open-mmlab/mmcv).

Environment

I have tried installing from the following 2 ways:

pip install mmcv-full -f https://download.openmmlab.com/mmcv/dist/cu122/torch2.2.1/index.html

pip install openmim
mim install mmcv-full==1.7.2

Both hang on "Building wheels for collected packages: mmcv-full" - I don't even know if it will resolve as I have not tried running it for more than 10 minutes as Colab is expensive, and requires to reinstall dependencies each time.

Is this expected?

Reproduces the problem - code sample

pip install openmim
mim install mmcv-full==1.7.2

Reproduces the problem - command or script

pip install openmim
mim install mmcv-full==1.7.2

Reproduces the problem - error message

hi, you could try to install ninja and psutil to speed up the building process.

pip install ninja psutil
