Closed tinastefaniewenzel closed 6 years ago

I ran make on MacOSX-10.12.5 (Sierra) and I get this error

python setup.py build_ext --inplace

I tried downgrading to numpy v1.9.2 as specified in the requirements.txt, but the error persists.

Hi @tinastefaniewenzel . Did you do this in the virtual environment?

I'm using Sierra 10.12.6, and I just ran these commands to set up the environment.

$ virtualenv env
$ source env/bin/activate
$ pip install -r requirements.txt
$ make

Closing because old. Try recloning the most recent master, and install. Thanks!
