Django fails to import any package : AttributeError: __name__

For some reasons, I had to reinstall Python on my desktop. Since then, my django applications are not working. I can create one, but as soon as I import a package anywhere in the application, I can't run python manage.py runserver
I can run another python script, I can start Jupyter Notebooks (and import the exact same packages in them). I also tried to create new projects with the "new" python installed, as soon as I add import pandas (or any other packages except django), I have the error.
The error message is quite long :

Got this annoying error after aborting an IDE-refactoring.
I suggest the following to reproduce the problem:
Revert git changes.
Make sure there are no cyclic imports in your code.
Reinstall virtual environment.
Unfortunately the error was still there in my case. So I knew the problem must be with python. And indeed:
Reinstalling python 3.7 solved the problem.

Did you pip install django?
I think when you reinstalled Python you didn't installed packaged like Django

Uninstall the current Django package and install Django 2.1.5
Use this command on windows:
pip install --user django==2.1.5

AttributeError: 'Coverage' object has no attribute '_harvest_data'
Any ideas ? I followed this manual exactly.

I found out the django-jenkins uses Coverage and in newest version of coverage the method _harvest_data has changed to get_data but in the final official release of django-jenkins it has not been applied so I switched to their latest git version and it solved.

django run server error with mysql

After I solve the issue with "image not found" when I run python manage.py syncdb by adding "export DYLD_LIBRARY_PATH=/usr/local/mysql/lib/" into .bash_profile.
The problem comes with python manage.py runserver
Does anyone know how to solve OSError(Errno 20)?

I just realize that I install both mysql-python and mysql-connector-python packages.
By changing the database 'ENGINE' setting from 'django.db.backends.mysql' to 'mysql.connector.django', the issue is solved.
Lesson learned here: I should probably use virtualenv to try different python package.

It's looks like not easy_thumbnails problem, because when I try to migrate my django-allauth it raises the same error.
Please, help me!

It seems like your django package was broken. Check that there is python2.7/site-packages/django/db/models/loading.py file in your environment. Or just reinstall django package.
pip install -U --force-reinstall django

I've installed all the packages needed to run those apps however is asking about requests, What is it about?

just do
pip install pyelasticsearch

If you just install requests module through pip this error should go away.
