i was installing Pytorch on Jetson nano, but the error appeared in the terminal.
Failed building wheel for numpy
Running setup.py clean for numpy
Complete output from command /usr/bin/python3 -u -c “import setuptools, tokenize;file=‘/tmp/pip-build-3ywdd1ol/numpy/setup.py’;f=getattr(tokenize, ‘open’, open)(file);code=f.read().replace(‘\r\n’, ‘\n’);f.close();exec(compile(code, file, ‘exec’))” clean --all:
Running from numpy source directory.
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).

Note: if you need reliable uninstall behavior, then install
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)
