Usually, if "guix weather python-umap-learn" says that there is no
substitute, then it is a bad sign. :-)

Thank you for pointing out the issue.  Using the Guix Data Service,

  
https://data.guix.gnu.org/repository/1/branch/master/package/python-umap-learn/output-history

one can see the versions which build and the ones which fail (mainly
because dependencies, apparently).  One the last Succeeded row, you
can click on the revision 2020-04-18 19:24:20 which indicates the last
known commit where python-umap-learn builds.  Therefore, you can run:

   guix time-machine --commit=cac674d99dc4a332e6210c57ec7f1b8164f66642 \
          -- package -i pyhton-umap-learn


Hope that helps.

All the best,
