Hi,
Thanks for tracking down the details. In summary the issue is the following: umap uses an approximate k-neighbor algorithm to find the n_neighbors
points closest to each point. Apparently that algorithm has failed to find the full n_neighbors
points (with the remaining neighbors set to a flag value of -1). As you note, this breaks a lot of stuff downstream in the code. First of all some better error checking so that a more sensible error message is displayed would be useful, so I'll try to get that done ASAP. After that it is a matter of tracking down why the approx knn algorithm is failing, which may take longer to sort out.

I believe I have resolved the error, but would appreciate it if you could check if that is the case using the current master. Let me know if it works now, thanks!

I have cloned your git :
git clone https://github.com/lmcinnes/umap.git
After i have done : python3 setup.py install
And i still have the same issue !

Match new calling convention better
5 hours before you answered me, have you push the fix ?
from umap.
I did indeed push the fix. I have found that I sometimes need to purge the previous version from my site-packages directory prior to a re-install before it takes. Could that be an issue?

Thanks a lot !
It is working great.
Good job.
