First, I downloaded the numpy+nlk whl file here and did
python3 -m pip install numpy‑1.11.3+mkl‑cp36‑none-any.whl
I renamed thanks to this tip: filename.whl is not supported wheel on this platform
But when I do
python3 -m pip install sklearn
I get Original error was: cannot import name 'multiarray'
I've tried unistalling and reinstalling numpy, but I have no idea how to fix this.
