This seems to relate to the problem of cython as mentioned here.
However, updating to the lastest version of cython did not solve this problem. I'm using python3.7 with Cython version 0.29.14.

Same here with DAWG package.

Do you use Windows (Visual C++) to compile C++ programs?
I encountered the same problem just now. Any help is welcome.

No. I make it on ubuntu. I use python3.6 instead of python3.7, then everything is fine

[geometrikal]

Had same problem installing from PyPI - pip install pydensecrf
If I installed with pip install git+https://github.com/lucasb-eyer/pydensecrf.git it works fine
