This should not have happened, a problem has occurred in Numba's internals.

could anyone please help me, I have successfully installed reticular and UMAP, but when I apply RunUMAP, it fails and shows the above error wanring

According to this error, UMAP is trying to run parallel Numba code in an unsupported environment, which is either Windows 32-bit or Windows with Python 2.7. Which is the case for you?

@117999 it has been over a year since the last activity on this issue. I am just checking in, to see if it is still applicable? Perhaps it has been resolved in the meantime or no longer occurs with recent versions of Numba?
