[stonebig]

when trying this on python-3.8.0a4 and cloudpickle-1.0.0, on Windows:

import cloudpickle

I get that error:

when I add a print.. well, I don't quite understand what I see:

    else:
        print (
            co.co_argcount,
            co.co_kwonlyargcount,
            co.co_nlocals,
            co.co_stacksize,
            co.co_flags,
            co.co_code,
            co.co_consts,

posted also on https://bugs.python.org/issue36886 , as maybe it's a python issue

[stonebig]

There may be code to change because of PEP 570, which added a parameter to the function that is used in Types module https://github.com/python/cpython/pull/12701/files#diff-cb0b9d6312c0d67f6d4aa1966766ceddL27

[stonebig]

would it be possible to include the change in vendored joblib ?
