This package PyPortfolioOpt is badly packaged upstream. We cannot do
better than warn about the issue:

guix import: warning: Failed to extract file:
PyPortfolioOpt-1.5.1.dist-info/METADATA from wheel.
guix import: warning: Cannot guess requirements from source archive: no
requires.txt file found.
guix import: warning: project name pyportfolioopt does not appear verbatim in
the PyPI URI
hint: The PyPI URI is:
`https://files.pythonhosted.org/packages/97/c2/c7569f2773f3e942367e90dcca15
a235af3d3330ac8abfcbfbe67a8ba8dd/PyPortfolioOpt-1.5.1.tar.gz'. You should
review the pypi-uri declaration in the generated package. You may need to
replace "pyportfolioopt" with a substring of the PyPI URI that identifies
the package.

Therefore, I am closing. Feel free to reopen if I missed a point.
