Numpy install failed on importing docker's python requirements

[clequinio5]

RUN pip3 install -r /src/requirements.txt

leads to:

Running setup.py clean for numpy
Failed building wheel for numpy
Complete output from command /usr/bin/python3 -u -c "import setuptools, tokenize;file='/tmp/pip-build-cgq4khra/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).
