Python: Uploading video to youtube using google provided code snippet does not work

Question

I'm trying to upload a video to Youtube using a python script.

So the code given here (upload_video.py) is supposed to work and I've followed the set up which includes enabling the Youtube API and getting OAuth secret keys and what not. You may notice that the code is in Python 2 so I used 2to3 to make it run with python3.7. The issue is that for some reason, I'm asked to login when I execute upload_video.py:

Now this should not be occuring as that's the whole point of having a client_secrets.json file, that you don't need to explicitly login. So once I exit this in-shell browser, Here's what I see:

Here's the first line:

/usr/lib/python3.7/site-packages/oauth2client/_helpers.py:255: UserWarning: Cannot access upload_video.py-oauth2.json: No such file or directory
  warnings.warn(_MISSING_FILE_MESSAGE.format(filename))

Now I don't understand why upload_video.py-oauth2.json is needed as in the upload_video.py file, the oauth2 secret file is set as "client_secrets.json".

Anyways, I created the file upload_video.py-oauth2.json and copied the contents of client_secrets.json to it. I didn't get the weird login then but I got another error:

Traceback (most recent call last):
  File "upload_video.py", line 177, in <module>
    youtube = get_authenticated_service(args)
  File "upload_video.py", line 80, in get_authenticated_service
    credentials = storage.get()
  File "/usr/lib/python3.7/site-packages/oauth2client/client.py", line 407, in get
    return self.locked_get()
  File "/usr/lib/python3.7/site-packages/oauth2client/file.py", line 54, in locked_get
    credentials = client.Credentials.new_from_json(content)
  File "/usr/lib/python3.7/site-packages/oauth2client/client.py", line 302, in new_from_json
    module_name = data['_module']
KeyError: '_module'

So basically now I've hit a dead end. Any ideas about what to do now?

See the code of function get_authenticated_service in upload_video.py: you should not create the file upload_video.py-oauth2.json by yourself! This file is created upon the completion of the OAuth2 flow via the call to run_flow within get_authenticated_service.

Also you may read the doc OAuth 2.0 for Mobile & Desktop Apps for thorough info about the authorization flow on standalone computers.
