After adding 'rest_framework.authtoken' to INSTALLED_APPS (settings.py) and running python manage.py migrate I started to get a strange error when trying to run django server (the strange thing is, that the error appears on every 2nd or 3rd attempt, sometimes the server starts running without the error):

I am using: django 2.2.7 and django rest_framework 3.10.3. Thanks for any help.

There's a ticket on Django's issue tracker discussing similar issue: https://code.djangoproject.com/ticket/30352.
For a temporary fix, you can remove all .pyc files on your project and run the runserver command again.
find <path-to-your-project> -type f -name '*.pyc' -delete
NB: I use pyenv which stores the project's virtual environment in a different directory outside the project directory. Removing only the project's .pyc files work for me, but you may also try removing the virtual environment's .pyc files if needed.
For anyone who still gets this error, please kindly comment in the issue page to help Django developers reproduce and fix the error.

django.core.exceptions.ImproperlyConfigured: WSGI application 'try_django.wsgi.application' could not be loaded; Error importing module.
I looked for solutions and found out that in the settings.py file I should change WSGI_APPLICATION = 'application' to WSGI_APPLICATION = 'wsgi.application' but it was already so in my settings.py file.

Based on the error it looks like you have an entry of simply 'blog' in your MIDDLEWARE settings. Django middleware requires a path to a class so 'blog' is not a valid value.
That's based on these lines from your traceback:
middleware = import_string(middleware_path)
File "/home/user/anaconda3/lib/python3.7/site-packages/django/utils/module_loading.py", line 15, in import_string
raise ImportError("%s doesn't look like a module path" % dotted_path) from err
ImportError: blog doesn't look like a module path

Django's server needs to find your application as defined in wsgi.py, so you need to set `WSGI_APPLICATION = '<project-name>.wsgi.application'.
See the docs at https://docs.djangoproject.com/en/2.1/howto/deployment/wsgi/
which state:
WSGI servers obtain the path to the application callable from their configuration. Django’s built-in server, namely the runserver command, reads it from the WSGI_APPLICATION setting. By default, it’s set to
<project_name>.wsgi.application, which points to the application callable in <project_name>/wsgi.py.

Django Crispy Forms

I am fairly new to Django and I have installed and am trying to use crispy forms in my web app.I have added crispy_forms to my installed apps with a comma after it. When I run the server I get this error:

I don't know what is wrong with my code. I have found some other users who have issues using crispy forms but are getting a different error. They were also unable to import crispy forms from the python shell but that is working for me. Even if I only add crispy forms to my installed apps without trying to apply it in my templates, I still get an error. Please let me know what I'm doing wrong. Thanks in advance.

Your version of django-crispy-forms is outdated, this has been fixed.
Update it by running:
pip install django-crispy-forms -U
-U makes pip upgrade your current installation to the newest.
You can find more about it by running pip install -h

The problem has been solved. I uninstalled the django version I had and used:
pip install Django==2.1.7
Thank you #YugandharChaudhari for helping me realize to change versions.
