mod_wsgi cannot load my Flask app

Question

I am trying to run my Flask application with mod_wsgi, but mod_wsgi gives the error Target WSGI script '/var/www/FDApp/fdapp.wsgi' cannot be loaded as Python module.

mod_wsgi: Compiled for Python/3.5.1+.
mod_wsgi: Runtime using Python/3.5.2.
mod_wsgi (pid=4142): Target WSGI script '/var/www/FDApp/fdapp.wsgi' cannot be loaded as Python module.
mod_wsgi (pid=4142): Exception occurred processing WSGI script '/var/www/FDApp/fdapp.wsgi'.
Traceback (most recent call last):
  File "/var/www/FDApp/fdapp.wsgi", line 6, in <module>
    from main import app as application
  File "/var/www/FDApp/main.py", line 15, in <module>
    import label_faces
  File "/var/www/FDApp/label_faces.py", line 2, in <module>
    import mxnet as mx
ImportError: No module named 'mxnet'

The mxnet package is installed in python3.5. All the packages are installed in this folder.

Change:

WSGIScriptAlias /fdapp /var/www/FDApp/fdapp.wsgi

to:

WSGIScriptAlias /fdapp /var/www/FDApp/fdapp.wsgi \
    process-group=fdapp application-group=%{GLOBAL}

You aren't telling mod_wsgi to run your application in the daemon process group.

Also, using:

python-home=/home/teja/.local/lib/python3.5/site-packages

is wrong.

For per user site-packages use:

python-path=/home/teja/.local/lib/python3.5/site-packages

Teja Over a year ago

I have change python-home to python-path.....and changed that WSGIScriptAlias tooo...But same error.Do i need to change any other?

The other problem is that the directory /home/teja is likely not accessible to the user that Apache runs as. You are better of creating a Python virtual environment under /var/www/FDap and install packages into that. Then use python-home to refer to the root of the Python virtual environment. See modwsgi.readthedocs.io/en/develop/user-guides/…
