Youtube_dl : ERROR : YouTube said: Unable to extract video data

I'm making a little graphic interface with Python 3 which should download a youtube video with its URL. I used the youtube_dl module for that. This is my code : import youtube_dl # Youtube_dl is used for download the video ydl_opt = {"outtmpl" : "/videos/%(title)s.%(ext)s", "format": "bestaudio/best"} # Here we give some advanced settings. outtmpl is used to define the path of the video that we are going to download def operation(link): """ Start the download operation """ try: with youtube_dl.YoutubeDL(ydl_opt) as yd: # The method YoutubeDL() take one argument which is a dictionary for changing default settings video = yd.download([link]) # Start the download result.set("Your video has been downloaded !") except Exception: result.set("Sorry, we got an error.") operation("https://youtube.com/watch?v=...") When I execute my code, I get this error: ERROR: YouTube said: Unable to extract video data I saw here that it was because it doesn't find any video info, how can I resolve this problem?
Updating youtube-dl helped me. Depending on the way you installed it, here are the commands: youtube-dl --update (self-update) pip install -U youtube-dl (via python) brew upgrade youtube-dl (macOS + homebrew) choco upgrade youtube-dl (Windows + Chocolatey)
