Python 3 script in LibreELEC 10

jim_p · September 26, 2021 at 3:05 PM

Probably not the right place to ask, but I am too tired to open a new thread now.

There is a python3 script I want to run on my le 10 x64 installation and it needs the requests library (python3-requests is the name of the package in debian).

And it fails to run because this python library is missing. Pip is also missing, so I can not install it by hand. Can I somehow use kodi's script.module.requests to run it?

Such a lazy attitude is not really appreciated. Just create a new thread next time.

Create and use:

Bash: pythonwrapper

#!/bin/sh
PYTHONPATH=
for addon in /storage/.kodi/addons/*/lib /storage/.kodi/addons/*/libs /usr/lib/kodi/addons/*/lib; do
  [ -d "${addon}" ] && PYTHONPATH="${PYTHONPATH:+${PYTHONPATH}:}${addon}"
done
export PYTHONPATH
exec /usr/bin/python "$@"

Please excuse my "lazyness". The past 2 days were exhausting for me. I was up at 5 am (on sunday too) and had to go through the day with all my nerves hitting "peak performance" for at least 12 hours straight.

Great! Now can I use it like so?

Code

pythonwrapper myscript.py

I will test it in 4+ hours.

Almost worked! Actually, the entire idea and the shell script worked as it should. If only the python script did not have that extra dependency for the the tqdm library

Python

from tqdm import tqdm
ModuleNotFoundError: No module named 'tqdm'

I will try removing the offending line and see how it goes...

**mglae** · September 28, 2021 at 10:35 PM

For a python only lib you can create /storage/.kodi/addons/tqdm/lib/tqdm and copy the library files into it.

jim_p · September 29, 2021 at 4:54 AM

That seems more doable than to remove all the references to that lib and its functions. I like it
But where can I find that lib? Debian gets it from here, but isn't this just the source code?

For a python only lib - not needing any external dependencies or including e.g. C/C++ code - the source is the lib. Try copying the files below the "tqdm" directory.

However creating a LE python lib addon is the correct way to go.

Do you mean everything shown in here? I will try it later then.

---edit!

It worked! Thank you very very much!

Now I have to make my bash script show some notification inside kodi. I think this good enough

Code

# kodi-send --action="Notification(Now Loading..., myscript.py)"

I know this is an old thread but it does refer to Libreelec 10 which I am running and the exact module I need python "requests". Can anyone help me to understand how to make this python wrapper work?

Is the "tqdm" a dependency for requests?

Thanks

jim_p · July 6, 2022 at 8:40 AM

Tqdm is a python library for progress bars, nothing more.

The requests library exists as a kodi addon in the main repo, so you can just ssh the libreelec system and run

Code

kodi-send --action="InstallAddon(script.module.requests)"

A prompt will appear on kodi, as shown in the screenshot below, so you just press yes there.

The reason for the above is that, since kodi 17, search does not return results for addons of the "script.module.*" family. If it did, you could just search for it from within kodi and install it as any other addon.

tekno · July 6, 2022 at 9:28 PM

Nothing happens when i use that command at ssh terminal, but I already have requests installed.

I can confirm it is an installed dependency for some addons I have installed. I do not see a way to install it directly.

In fact, searching for addon called "requests" causes Kodi to crash, but searching for other addons does not. I think that is a bug.

Code

 python3 myscript.py
Traceback (most recent call last):
  File "myscript.py", line 4, in <module>
    import requests
ModuleNotFoundError: No module named 'requests'

tekno · July 7, 2022 at 1:36 AM

Ok so here is what I did and this worked!

I copied the "wrapper" script above.

Bash

#!/bin/sh
PYTHONPATH=
for addon in /storage/.kodi/addons/*/lib /storage/.kodi/addons/*/libs /usr/lib/kodi/addons/*/lib; do
  [ -d "${addon}" ] && PYTHONPATH="${PYTHONPATH:+${PYTHONPATH}:}${addon}"
done
export PYTHONPATH
exec /usr/bin/python "$@"

Saved it as pythonwrapper.sh then made it executable

from the directory where the pythonwrapper.sh file is...

Code

chmod +x pythonwrapper.sh

then I executed

Code

./pythonwrapper.sh .kodi/frndlytv/myscript.py --PORT 8080 --PARAMETER1 "ABC" --PARAMETER2 "XYZ"

and it worked!

About that. Yes, kodi will not show the dialog box if the addon is already installed, even if it is installed and deactivated. It will just ignore the "request" to install it.

any idea on how to get cryptography module?

jim_p · July 8, 2022 at 5:41 AM

No idea, sorry

I just checked my installation and is no python directory under /usr/lib/, as there is on my distro.

tekno · July 8, 2022 at 7:05 AM

I suspect that one of the addons I have installed is a cryptography module , but not sure. Maybe this one?

script.module.cryptolib

~/.kodi/addons/script.module.cryptolib # ls -l

total 28

and they go on from there...

jim_p · July 8, 2022 at 12:31 PM

I do not have such a folder in there, neither on my pc (kodi 19 on x64 linux), nor on the libreelec x64 installation.

The same applies to script.module.* stuff that is under /usr/share/kodi/addons/.
