LoweringError: Failed in nopython mode pipeline (step: native lowering)
When trying to do the following, I get several errors.
import umap.umap_ as UMAP
I asked this same question in stackoverflow but didn't receive any solution there (already tried a couple solutions which I posted there). But, I'm not sure how to fix this issue at all & really need umap to function right now-- have a deadline for this project tomorrow (not sure why this all of a sudden isn't working). Should I just delete anaconda3 & all python packages and start from scratch?

numba is 0.53.0 and umap learn is 0.5.3. Does it matter that umap has "pypi" as channel and "pypi_0" as build and numba doesn't? both in anaconda3
There are a number of reasons it could be having problems. It's hard to diagnose with more detail (and the error messages from numba are unfortunately very long, so it can be hard/annoying to dump the whole thing in an issue). I would try a reinstall from scratch because it may be getting stuck somewhere. In terms of channels: I would recommend getting numba from a numba channel, pynndescent and umap-learn from the conda-forge channel, and everything else from the standard anaconda channel.

numba is 0.55.1 and umap learn is 0.5.2. Does it matter that umap has "pypi" as channel and numba doesn't? both in anaconda3

@lmcinnes Hi, so I created a new anaconda environment & reinstalled everything from scratch but now I get this error: https://stackoverflow.com/questions/72258172/importerror-cannot-import-name-nndescent Any idea what this means? I don't understand why "NNDESCENT" is the problem as it should be in its pynndescent package.
I admit to being a little baffled. If pynndescent is installed it should be able to find NNDescent in it; is it possible envrionments are getting crossed or confused somehow? I'm sorry I can't be more help, but this is a very confusing case.
My generic advice with any such problem is to create a new conda environment from scratch. You shouldn't need to delete anaconda3 to start over again.
Cheers John
