I am trying to make a facial recognition system using the Jetson Nano developer kit, I set up my Micro SD card following the Nvidia website and then updated the APT. I created the swapfile to install NUMPY but when I run ‘pip3 install numpy’ it gives me the following error, and i am not sure how to fix it.
pip3 install numpy

setup.py clean is not supported, use one of the following instead:
- `git clean -xdf` (cleans all files)
- `git clean -Xdf` (cleans all versioned files, doesn't touch
files that aren't checked into the git repo)
Add --force to your command to use it anyway if you must (unsupported).

with pip instead of using `setup.py install`:
- `pip install .` (from a git repo or downloaded source
release)
- `pip install numpy` (last NumPy release on PyPi)
