Pytube: KeyError: 'cipher'

[MrspiLLnyK]

When I try to download "https://www.youtube.com/watch?v=SiAuAJBZuGs" - successful
But "https://www.youtube.com/watch?v=wmQx_K9Gwrc" - KeyError: 'cipher'

Traceback (most recent call last):
  File "C:\Users\mark\AppData\Local\Programs\Python\Python37-32\lib\site-packages\pytube\extract.py", line 297, in apply_descrambler

During handling of the above exception, another exception occurred:

I have fixed this issue by changing a few lines in extract.py

cipher_url = [
                parse_qs(formats[i]["cipher"]) for i, data in enumerate(formats)
            ]

cipher_url = [
                parse_qs(formats[i]["signatureCipher"]) for i, data in enumerate(formats)
            ]

You can use left sidebar of colab and from there goto /usr/local/lib/python3.6/dist-packages/pytube/extraxt.py
