python - Flask hangs after importing pandas (also numpy, matplotlib etc.)

Question

Why is Flask hanging after importing the pandas lib or several other scientific libs? It still works, when running it locally via SSH, but when visiting the URL the browser loads and loads and nothing happens.

Answer 1

The solution is for Ubuntu with Apache2 server. You have to configure the following file:

/etc/apache2/sites-available/your-flask-app-file.conf

paste the following line below WSGIScriptAlias:

WSGIApplicationGroup %{GLOBAL}
