Numpy ImportError when deploying Flask App using mod_wsgi/Apache2

Question

I\'m trying to get a Flask app running on AWS EC2 (standard Ubuntu AMI) through an Apache2 Webserver. My app internally uses Numpy. I have tested the following:

Answer 1

This:

site.addsitedir('/home/ubuntu/.local/lib/python2.7/site-packages/numpy')

should have been:

site.addsitedir('/home/ubuntu/.local/lib/python2.7/site-packages')

But the whole way you are setting up Python virtual environments is not best practice anyway. Suggest you read:

• http://modwsgi.readthedocs.io/en/develop/user-guides/virtual-environments.html

Also try and switch to daemon mode, it is better to use daemon mode than embedded mode.

Answer 2

numpy via pip is not installed at /home/ubuntu/.local/lib/python2.7/site-packages but it should be at /home/ubuntu/.local/lib64/python2.7/site-packages or something like that.

Just try add another site.addsitedir in your app.wsgi to that folder should work. Something like this :

site.addsitedir('/home/ubuntu/.local/lib64/python2.7/site-packages')
