I’m closing this out due to lack of communication and detail from the original poster. I suspect that there’s nothing wrong on our side though, and whatever problem exists is upstream (eg via numba or llvmlite).

@tuanio if you want to provide more detail, we can reopen and discuss.

Perhaps @tuanio meant the environment is a Kaggle kernel in case it’s something like Python 3.7 on Ubuntu 20.04 on Intel CPUs.
