no attribute __reduce_cython__

See original GitHub issue

https://github.com/cython/cython/issues/1894#issuecomment-339966952.

I’m getting an AttributeError due to a missing __reduce_cython__ attribute in an embedded environment when I build lxml with Cython 0.26 or 0.27. 0.25(.2) works fine. The issue seems to be triggered by reinitializing the environment but unfortunately I was not able to find a minimal sample that replicates it yet.

I did a git-bisect and found https://github.com/cython/cython/commit/f8b3405e926d2ba9bc2ee24d79848235875ee12e to be the first broken commit.

Will try to find a simple test case, but I’m not sure how soon I’ll have a result.

EDIT: This was resolved in Cython 0.28. See https://github.com/cython/cython/issues/1953#issuecomment-398128940.

@eliaperantoni I got AttributeError: type object ‘pandas._libs.tslib._TSObject’ has no attribute ‘reduce_cython’ as well. I solved this problem by using pandas-0.20.3, cython-0.27.3 and python-3.5.

One more thing to add, since it came up along the way: calling Py_Initialize() after Py_Finalize() is not actually supported in CPython: https://bugs.python.org/issue34309
