问题
I use dill
to save ML model to file.
When I run my tests with python -m unittest
it works. But if I try run tests with python setup.py test
it getting error TypeError: can't pickle PyCapsule objects
in raw where I try to save model.
My settings in setup.py for testing:
test_suite='tests',
tests_require=['pytest']
Error:

TypeError: can't pickle PyCapsule objects
Could you help me to know why it doesn't work?
回答1:
I'm the dill
author. This is a known open issue for dill
. See: https://github.com/uqfoundation/dill/issues/106. Essentially, a serialization function for PyCapsule
objects has not yet been registered in dill
.
