Unable to Download videos in KA-Lite 0.16.7 on Windows7

[yogeshmr]

Summary

I have downloaded videos in bulk from Torrent when I was having KA-Lite 0.16.5 and using it smoothly. I did a fresh installation of KA-Lite 0.16.7 and copied all the videos and assessment files to "content" folder. I scanned the videos and everything got detected and working without any issue.

In the Videos tab, I found that few chapters do not have videos and hence wanted to download the videos discretely for those chapters. But this feature is not working.

System information

Please specify the KA Lite version you were using and your operating system!

• Operating system: Windows 7
• Version: 0.16.7
• Browser: Chrome

Traceback or relevant snippet from server.log

INSERT TRACEBACK, LOG MESSAGES ETC. HERE

How to reproduce

1. Login to KA-Lite 0.16.7 as administrator
2. Click on Manage -> Videos
3. Click on any subject which is partially green or completely blank.
4. Select one or more videos for downloading
5. Click on Download Videos button.

Screenshots

The below snapshot shows the error message:

The below snapshot shows my content folder directory:

Real-life consequences (anything community should be aware, for instance how it affects your deployment)

Since the bulk download of videos using Torrent has few content videos missing, they cannot be downloaded interactively as well and thus completely missing out on those contents.

Hi @yogeshmr - thanks for reporting!

This is definitely because requests is the wrong version. Would you be able to run kalite shell from your command line?

If the command doesn't exist, try doing cd C:\path\to\where\python\is\installed. Example:

cd c:\python27\Scripts
kalite shell
import requests
print requests.__name__
print requests.__version__

The output can help us identify what's wrong...

Because of a bug in Windows, we don't have logging #5057

Hi @benjaoming - Thank you very much for the quick response!

Please find below the output after running the above commands:

C:>cd Python27

C:\Python27>cd Scripts

@yogeshmr - I think I know what the issue is now. After upgrading, .pyc files have not been deleted in ka-lite/python-packages.

If you could locate and delete all the pyc files and delete them -- you should probably use a file search to do it.

I had a mistake in the commands I asked you to run -- if you replace __name__ with __file__, you will see the path of the pyc file that's from the previous install.

#3952 will solve this issue permanently so it doesn't have to fixed in the windows installer.

@yogeshmr any luck?

[yogeshmr]

@benjaoming I deleted all the .pyc files using the "Search Everything" tool. The .pyc files keep reappearing with every action. But even after deleting all the .pyc files, the video download still has error.

[benjaoming]

@yogeshmr - after deleting the *pyc files, could you try running the commands from before again? I.e.:

C:>cd Python27
C:\Python27>cd Scripts
C:\Python27\Scripts>kalite shell

>>> import requests
>>> print requests.__file__
>>> print requests.__version__

@benjaoming

After deleting the *.pyc file completely, I ran the above commands and obtained below response:

The Video downloads is throwing below error message:

[benjaoming]

@yogeshmr thanks for investigating again! It seems that it's not just the *pyc files from your previous install that weren't removed at the upgrade. It's the whole folder in C:\Python27\share\kalite\python-packages\requests that you should remove. After that, restart the server, and it should be fine.

If you can confirm that this works, I'll add this in the docs for other potential Windows users that are upgrading from 0.15.

@benjaoming Its (the video downloads) working after deleting all the contents of the requests folder in C:\Python27\share\kalite\python-packages\requests.

Thank you very much for your great support!

Thanks for the feedback! Glad we could solve it. I'm adding it to the known issues, but we have to mark it as a wontfix, because a subsequent 0.17 will deal with the underlying cause of the unpruned directory.

Please feel welcome with all further technical issues here on Github or in our community support forums :)
