Problem with lazyImport on MacOS if module is not already imported
joezuntz opened this issue · comments
This is low priority as there is an easy workaround, but I've seen a strange issue with the lazyImport mechanism on MacOS which seems to be triggered when h5py is compiled against MPI.
When I try to import tables_io I get this:
Traceback (most recent call last):

If I import h5py first and then tables_io then it works fine. This didn't happen on linux for me, just MacOS (only tested with conda and on intel). I've attached a script that recreates the issue (renamed to a txt file to enable uploading it here).
fixed in #41
