KA Lite substitles 0.16.9 under Linux Ubuntu #76

Closed JMNB closed 6 years ago

JMNB commented 6 years ago

We have a problem with the English sub-titles in KA-lite version 0.16.9. Although we have downloaded the language pack, and we indicate that we want to see the sub-titles,they are not displayed.

For various reasons we cannot upgrade KA-Lite to version 0.17.

We run KA-lite on a Linux server, Ubuntu 16.04.3 LTS.

Hi @JMNB

Thank you for posting and sorry for the late reply.

May I ask how long have you been using KA-Lite and those various reasons why you can't upgrade to 0.17

I tried the following to find out whether it's a KA-Lite version issue or a content pack issue:

Here is what I noticed:

On 0.17.x installers, it copies the subtitles to ~/.kalite/content/srt/{lang_code}/subtitles/. On 0.16.9 installer, it copies the subtitles to ~/.kalite/httpsrv/static/srt/{lang_code}/subtitles/ but when you open the said folder, you won't see any subtitle files (*.vtt)

@benjaoming perhaps you have any ideas about this?

benjaoming commented 6 years ago

@mrpau-eugene I can confirm that there are no subtitle files in assessment items for 0.16.9. I think maybe we had an understanding that the English content pack shouldn't contain subtitles in 0.16 -- a misunderstanding of course. But I think we excluded the subtitles in the English content pack, together with certain dubbed language content packs where the subtitles were translations of a different audio track (not captions).

benjaoming commented 6 years ago

@JMNB 0.17 had updates to make English subtitles display by default. I think you should update if you can :)

What are the challenges?

JMNB commented 6 years ago

Dear Benjamin and Eugene,

Thank you for your answer and let’s explain the background for our question:

Last three years we’ve been working with a high school in Addis Ababa, Ethiopia, to introduce e-learning.

This high school is part of an organization called Selam Children’s Village. This organization, founded 30 years ago by Mrs. Tsehay Roeschli, to take care of orphans and destitute community children to improve their lives and holistically develop as self-sufficient citizens, http://www.selamchildrenvillage.org http://www.selamchildrenvillage.org/.

Our approach has been to create summaries of the Ethiopian text books for biology, chemistry, mathematics, physics, and history, geography. The summaries we linked to graphics, animations, exercises and video tutorials, making it an integral part of it by adding links.

We looked for high -quality video lectures off-line available under a Creative Commons-no-commercial license and found the Khan Academy. KA-lite has become our prime source for Mathematics and Science.

Students and teachers at the Selam High School have now access to world class material, integrated into the Ethiopian curriculum.

The quality of the materials also has been recognized by the Ethiopian government, i.e., the Education Bureau of Addis Ababa, and they requested us to support them in introducing the e-learning at governmental high schools, starting in Addis Ababa. We hope this opportunity will eventually make it available to Ethiopian students in Addis Ababa, and maybe also the rural areas - where there are more than 60 students in one class, and schools organize the classes in multiple shifts, because a shortage of teachers and class rooms.

Last year we installed a first version on the e-Learning summaries on RaspberryPI’s using KA-lite 0.16, with help of Benjamin; each subject has its own RaspberryPI. The students are using the subtitles, because that give them a better understanding of the material. Their textbooks are in English as well.

For maintainability and extended use possibilities we transferred the RaspberryPI e-Learning to a Linux-Ubuntu webserver.

We also installed KA-lite 0.17, but we found out that the database tree for the video lectures and exercises was modified, meaning for us that we had to modify partly and test all (1500 +) links in the e-Learning material to KA-lite. We considered this option, but taking in mind that Debian and Ubuntu are not that different we decided to continue using KA-lite 0.16.

Later we found out that there was a problem with the subtitles after re-installation and re-testing, we contacted you asking for help and support.

We hope you will understand our considerations and challenges, but we also want to thank you for the work done making the Ka-lite video lectures and exercises available offline.

Kind regards,

Wim and Julia Nolles

@JMNB

I would like to suggest to use the 0.17.x installers. Content packs are not depended to the KA-Lite version you are using.

You can install 0.17.3 with the 0.16.x content packs.

So if ever you install 0.17.3 installer, you can remove the contents by deleting the ~/.kalite folder.

And then run kalite manage setup

0.16.x english content pack can be found here.

@benjaoming please correct me if I'm wrong. thanks 😄

benjaoming commented 6 years ago

What @mrpau-eugene seems to make sense in your situation @JMNB -- try installing KA Lite 0.17 without the content pack bundled (use either the ka-lite-raspberry-pi or ka-lite package for Debian, but *not* the ka-lite-bundle).

We also installed KA-lite 0.17, but we found out that the database tree for the video lectures and exercises was modified, meaning for us that we had to modify partly and test all (1500 +) links in the e-Learning material to KA-lite. We considered this option, but taking in mind that Debian and Ubuntu are not that different we decided to continue using KA-lite 0.16.

Our tests show that you can use KA Lite 0.17 with the content pack from 0.16. Links and videos will thus remain the same. Just upgrade the software and leave the contents as they are. Thanks @mrpau-eugene for the research here!

Small note: After installing, you should see that some very long-lasting content annotation takes place, this is an issue that we are aware of, basically KA Lite scans for all of the videos in the database, even though the database hasn't changed.

Another possibility is to install the server from scratch with first Ubuntu, followed by kalite 0.16.9, Debian 0.17.3 ?

Dear Eugene and Benjamin,

Meanwhile We tried the second option: Install Ubuntu from scratch, followed by KAlite 0.16.9 and Debian-RaspberryPI 0.17.3 according to the instructions on the Learning equality website.

But the KAlite installer ran into problems telling that he was missing something on nginx . . We tried to install it, but were not successful.

Have a nice evening, Wim and Julia

And then download the 0.16.9 content packs here: http://pantry.learningequality.org/downloads/ka-lite/0.16/content/contentpacks/en.zip

I haven't tested it yet since I don't have a raspberry pi with me but most likely you will have a similar output from the one I posted since it will prompt you the location of the content packs

JMNB commented 6 years ago

Sorry Eugene for the misunderstanding:

These messages were displayed on the screen as you mentioned. We will download the content pack for 0.16.9 in the ~/Downloads directory and will do another try today.

We are working in a lIinux- Ubuntu platform, although in the past we used a RaspberryPI and Benjamin helped us.

Dear Eugene and Benjamin,

Yes, we were successful today and managed to install KALite 0.17.3 with the 0.16.9 database and subtitles thanks to you commands and support.

We only see a message when in the home-page of KALite:

Dear Admin, please log in and upgrade the following languages as soon as possible: English

Please find attached document describing what we did.

Thank you also on behalf of the Ethiopian students, so they have now the opportunity to listen and read in English what is told in the video lectures. Perhaps some video lectures will be subtitles by Amharic, their own language. We will keep you informed.

Please note that KAlite is not started automatically after boot; this must be added manually in the 'startup applications' of Ubuntu.

benjaoming commented 6 years ago

@JMNB

Thanks for the feedback!

KA Lite is supposedly started at boot (unless there was a deviation in the 0.16 series) but this can be dependent on the choices of a previous installation where you might have made a different setting.

Adding it to "Startup applications" is a valid choice, but it's dependent on whether the user is logged into the desktop, because that's when it triggers.

The alternative would be to run sudo systemctl enable ka-lite to make it start at boot.

Good luck with the deployments in Ethiopia, and always happy to help if you have further questions. Be sure to check out the deployments map, too, if you haven't already:
