CompileError: toolkit/utils/region.pyx

[al1can]

Hi everybody, I'm having a problem with building region.c. I followed the instructions in INSTALL.md and when I ran python setup.py build_ext --inplace I'm getting the following in the terminal. Had the same results when I do bash install.sh too. I tried it both in Windows 11 and Ubuntu 22.04 in Virtualbox. I'm using miniconda3.

Thanks in advance.

Compiling toolkit/utils/region.pyx because it changed.

omg,same.do u have the solution?thanks!

[L1n0A0]

Me too. Can anyone suggest a solution？thanks!!

[ZXW2001]

Same, Do you guys solved it? Thanks!

[Archie945]

i solved it,change python to 3.6 and install cython0.28

[ZXW2001]

@Archie945 Thank you so much!

[al1can]

@Archie945 Thanks for the solution.
