SystemError: initialization of _internal failed without raising an exception

[snayfach]

I installed on a cori login node using conda which ran without errors:
conda create -n genomad-conda -c conda-forge -c bioconda genomad

After activating and testing it produces errors:

source activate genomad-conda
genomad

Traceback (most recent call last):

Here's a stack overflow thread on the issue: numba/numba#8615

From skimming that, the issue might be the latest version of numpy and installing a lower version of numpy (<1.24) may fix the problem.

Update: that was the solution for me

conda remove --force numpy
conda install numpy=1.23.5 

There was another version of numpy install with conda I had to remove as well

Thanks for reporting this! I'll release a new version with a numpy < 1.24 requirement. Hopefully Numba will add support for the new numpy release soon.
