Hi,

I get errors for most videos, too.
It started giving errors today, a few days ago everything worked as it should.

Maybe there was a change by YouTube?
Some kind of function renaming, so the regex doesn't find anything anymore?

Here the intersting part of my Stacktrace:

.format(pattern=pattern),
pytube.exceptions.RegexMatchError: regex pattern (\w+.(\w+)(\w,(\d+))) had zero matches

I am using the current version available via pip on python 3.5.

Thanks for this great project, pytube is awesome :)

Hi @ajayrandhawa
Did you manage to fix it?
Can you share your solution with me, please?

[CNugteren]

Even the example in the README is now broken:

[ajayrandhawa]

I think it is from youtube side. now my project works properly.

[mrgrue]

With pytube-9.2.2 on Python 2.7.15 the READM example above from @CNugteren is failing for me as well.

[traysonr]

Anybody know what it going on with this?

My pytube was downloading strong and suddenly no videos work.

Here are my errors:

yt = pytube.YouTube(str(line))

File "build/bdist.linux-armv6l/egg/pytube/__main__.py", line 88, in __init__
File "build/bdist.linux-armv6l/egg/pytube/__main__.py", line 97, in prefetch_init

Any help is appreciated.

I was just learning to use pytube and I sumbled upon the same issue.
It crashes also due to that same RegexMatchError, at the moment of retrieving the video from YouTube (yt = YouTube(...whatever...)).

[Fatman13]

I had the same issue. Upgrade to pytube 9.2.3 and it worked again.

pip install pytube --upgrade

[Mahdi-Hosseinali]

Updated to pytube 9.3.5 and still have the problem:

from pytube import YouTube
yt=YouTube('https://www.youtube.com/watch?v=FeIUmACQGOo')

RegexMatchError: regex pattern (yt.akamaized.net/)\s\|\|\s.?\sc\s&&\sd.set([^,]+\s,\s(?P[a-zA-Z0-9$]+)() had zero matches

[dehopp]

Using also pytube 9.3.5 and python 3.6.6 and also have the error on multiple videos in a playlist:

Error on download : regex pattern (yt.akamaized.net/)\s\|\|\s.?\sc\s&&\sd.set([^,]+\s,\s(?P[a-zA-Z0-9$]+)() had zero matches

[traysonr]

I updated and mine worked. Although I got similar errors when I didn't
input a youtube video url in the correct format. Experiment with that.

What is the correct format? I'm trying to download a playlist and this is the pytube finds itself.

Can you maybe give a working URL as example?
Just to test if it works for others, too? Or recognize a pattern.

[traysonr]

See that's probably your problem. Pytube is meant to work with one video
URL (to my understanding). So you cannot download an entire playlist.

Your input for youtube URL must be like:
https://www.youtube.com/watch?v=uQRIvXymJZI

I noticed that some links would throw an error if they were to one of those
live "radio" streaming channels, sometimes radio would be in the link. I
also tried using a link that I copied from my mobile app, and that didn't
work. I realized that the url was slightly different. So a playlist
probably would not work.

Experiment with it.

pytube is definitely meant for downloading playlists. You must only use
pl = Playlist("my_playlist_link")
instead of
yt = YouTube("my_vid_link")
for that

Your link is working, but for example this one:
https://www.youtube.com/watch?v=EKF6ghfcQic
does not. I honestly cannot see the difference.

from pytube import YouTube
yt = YouTube("https://www.youtube.com/watch?v=EKF6ghfcQic")

Hi. Weird as it sounds, after some trials with different videos it seems the error appears only with videos featuring copyrighted music. Like, Youtube has further protected those somehow within the code, and thus they give an error when pytube tries to search for them.

So videos featuring music from youtube creators instead of "real" album tracks are fine, since I guess it's the content id algorithm the one checking for all this stuff (it works for example with Jaime Altozano's "Trap del Terraplanismo", or with any non-music video you happen to find).

[santosh2702]

Yeah, this is Right this problem is not with all videos code works with genuine videos of all channels

[oliviernguyenquoc]

Can you re-open the issue with a tag "feature request" to have a clean exception raised when it encounter this unusual case ?

Do you think it could be a good idea ?

[traysonr]

I can look into it after work if I remember. Honestly the issue has been
resolved.

I updated my code to catch errors and handle them by logging them and
resuming. This way, if one video has errors associated with it, the whole
program won't crash.

In the event all videos give you an error, completely uninstall and purge
pytube and reinstall the latest version from github.

It's been working flawlessly for record time now.

Hope this helps anybody struggling!
