[FIXED] ModuleNotFoundError: No module named 'django_plotly_dash'

Issue

I am creating a web application using django_plotly_dash, a module combining Django, Plotly, and Dash into one package. I am running into an issue where when I try to work with the manage.py file to run commands, I get the error ModuleNotFoundError: No module named 'django_plotly_dash'

From research and the traceback, it seems to problem lies either in my settings.py file specifically with static files/bootstrapping or in my directory structure. Does anybody with more experience with this see any issues in my structures or settings.py that are causing this error

Here is the Traceback message:

If it helps, I was following the following tutorial on using this package:

Please let me know if any further info will help with solving this.

Solution

After tinkering, it seems like @yagus was right. I created a new virtualenv and redid the pip installations and now it works. I must have set it up wrong the first time. Thanks for the help @yagus
