ImportError: cannot import name 'multiarray' with Apache/mod_wsgi
See original GitHub issueI’m trying to deploy a Flask-based application (Python 3) in AWS EC2 using Apache and mod_wsgi with all the necessary packages being installed in a miniconda environment.
Bellow you can find my app.wsgi file:
import sys
import logging
import site
site.addsitedir('/home/ubuntu/miniconda3/envs/app_env/lib/python3.6/site-packages/')
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,"/var/www/html/flaskapp/")
sys.stdout = sys.stderr
from app import app as application
Also, here’s my Apache config file:
ServerAdmin webmaster@localhost
DocumentRoot /var/www/html
WSGIDaemonProcess flaskapp threads=5 python-home=/home/ubuntu/miniconda3/envs/app_env
WSGIScriptAlias / /var/www/html/flaskapp/app.wsgi
<Directory flaskapp>
WSGIProcessGroup flaskapp
WSGIApplicationGroup %{GLOBAL}
Order deny,allow
Allow from all
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
However, when I reload my server, I keep getting the same error:

I’ve tried multiple times to reinstall numpy and create a new conda environment but the problem seems to be persisting. Moreover, if I activate my conda env I can import directly multiarray (from numpy.core import multiarray). The app also runs perfectly if I load it directly as a localhost (python app.py). Is there some peculiarity when trying to import numpy via mod_wsgi?
Thanks!

I don’t know if this is your issue or not, but as a heads up: in general numpy and mod_wsgi are not compatible. (mod_wsgi is one of two known applications that uses CPython’s “subinterpreter” support, and making numpy work with subinterpreters is somewhere between “a lot of work” and “impossible without new interpreter features”. So far no-one has been motivated to figure it out, given that there are about a dozen mod_wsgi alternatives that don’t have this issue.)
I think we can close this as wontfix/invalid, there’s nothing actionable here as far as I can tell.
