Could not build wheels for bottleneck which use PEP 517 and cannot be installed directly
I post the answer to such error in case someone comes across it as I did.
The GitHub Thread does not solves the error for Windows.
As the PyPy page suggests:
To install bottleneck on Windows, first install MinGW and add it to your system path. Then install Bottleneck with the command:
python setup.py install --compiler=mingw32 Alternatively, you can use the Windows binaries created by Christoph Gohlke: http://www.lfd.uci.edu/~gohlke/pythonlibs/#bottleneck
Such wheel solves the issue.
