@dzlob You need to put the flags you want to use separated by | in the variable tst_flags. For instance, fastai2 has the line:
tst_flags = slow|cuda|cpp
(or it will very soon since I realize it’s missing!)
@adamh We will add conda support (and make it as easy as release on pypi for the packages you build with nbdev) very soon
@nextM Do you ahve this problem after doing a dev install or a pip install?
