I'm facing the same issue were you able to solve it!

[Manojkumarjala]

did anybody solved it

[quocnhat]

solved. just " pip install cython "

[Espade]

solved the problem by "sudo pip install cython" then do make command

[khan958]

@Espade But i already installed cython.

[alibabadoufu]

I am having the same problem and I have also installed cython but the problem still persists

[namhar]

Having this issue as well. Tried everything short of nuking the computer and starting from scratch.

[kmrtanmay]

use pip3 install cython. It will help

[parthkvv]

I used pip install cython, but the issue still persists. Did anyone find the solution?
