Not able to download videos

Hi All:

I am facing a problem with the script for the last two days. I have upgraded the script. I have stopped calling coursera_dl.py. Instead, as recommended, I am calling coursera-dl from the top directory. Here is the error: casebasedbiostat-001 Downloading class: casebasedbiostat-001 Traceback (most recent call last): File "c:\z\coursera\coursera\coursera-dl", line 6, in coursera_dl.main() File "c:\z\coursera\coursera\coursera\coursera_dl.py", line 693, in main if download_class(args, class_name): File "c:\z\coursera\coursera\coursera\coursera_dl.py", line 648, in download_class username=args.username, password=args.password File "c:\z\coursera\coursera\coursera\cookies.py", line 320, in get_cookies_for_class session.cookies.update(cookies) File "C:\Anaconda\lib_abcoll.py", line 494, in update self[key] = other[key] File "C:\Anaconda\lib\site-packages\requests\cookies.py", line 241, in getitem return self._find_no_duplicates(name) File "C:\Anaconda\lib\site-packages\requests\cookies.py", line 282, in _find_no_duplicates raise KeyError('name=%r, domain=%r, path=%r' % (name, domain, path)) KeyError: "name=Cookie(version=0, name='csrf_token', value='Hsa8Q5jWGacAABdlDU8o', port=None, port_specified=False, domain='class.coursera.org', domain_specified=False, domain_initial_dot=False, path='/compmethods-003', path_specified=False, secure=False, expires=1378357039, discard=False, comment=None, comment_url=None, rest={}, rfc2109=False), domain=None, path=None"

Here you are trying to download casebasedbiostat-001.

(...)

Here the authentication cookie is for compmethods-003? Are you trying to download more than one course?

Can you post the entire output of calling the script with the --debug option passed, including the command line? (Feel free to obfuscate only your password and, possibly, your user, but leave the rest untouched).

Also, which versions of the packages are you using? In particular, which versions of the modules does pip report that you have installed? Any further information that we should know to help us help you?

What is the output of git show? Does it show the commit 088f4b96af91ebcf9a25f56b7402bd37e0d69a7b? Does it show my name? If you want some guidance collecting information about your system, please take a look at:

Ah, thanks for your pip output. That was very useful.

I noticed that you are using a pre-1.0 version of requests. Please, upgrade to a version post 1.2 (I use 1.2.3 locally). requests has changed its interface a lot. Please, report back what you see.

Thank you very much for pointing out the older version of requests. I upgraded it to 1.2.3. However, I face a problem with casebasedbiostat-001 still.

That's great.

However, I face a problem with casebasedbiostat-001 still.

Does the script work with other courses, so that we can begin isolating the problems?

Humm, I have no experience with Windows and the limitations in path lenghts etc. Can you, just for the sake of debugging, use an external downloader like wget, curl or aria2c?

Our homegrown downloader is certainly way more limited than the specialized downloaders that I mentioned.

If the external downloaders don't work, then please send the entire output when running with the --debug option, as it will reveal what we may be trying to do under the hood.

Thanks,

I just enrolled in this class and the titles of the sections are gloriously long; in my ipython shell, I get this (certainly going to be messed up):

That is, simply that part of the path may already mess up with filesystem limitations (especially in systems where PATH_MAX is relatively low). While I have no problems with my Linux system, it will certainly be nice to see how other tools cope with that.

Thank you, for trying it out. I tried it out of Cygwin terminal. Same error. Perhaps, we can ignore this error for now since the file names are too long. What I will do is that I shall download them onto my Linux desktop. If need be, I shall rename the files and ftp them to my windows box. Thank you.

Regards,

Ramana

Humm, I have no experience with Windows and the limitations in path lenghts etc. Can you, just for the sake of debugging, use an external downloader like wget, curl or aria2c?

Is this issue fixed somehow? I have Windows as my main platform. Perhaps I can help.

Thanks for the bug triage, Victor. I guess that the remaining bits of this bug (namely, downloading files with very long filenames under Windows) is already covered by other bug reports.

Thanks to everyone involved!
