app.language has no attribute languages

[MiguelMJ]

Hi!
I'm launching the app with these options: --load-only es,en,fr --disable-web-ui but the models don't update: I get the following message:

Cannot update models (normal if you're offline): module 'app.language' has no attribute 'languages'

As the message says, app.language has no attribute languages, but still it is accessed in init.py, lines 58 and 68.

I haven't found any other place where app.language.languages is used, via grep -nr "app.language.languages" and grep -nr "from app.language" so I guessed that maybe those lines were meant to access app.language.__languages. However changing those lines to use app.language.__languages only changes the error to:

Cannot update models (normal if you're offline): 'NoneType' object is not iterable

I understand that this happens because the line 58, that would assign app.language.__languages a value, is never executed and line 68 tries to iterate through its default value: None.

Some solutions I came up with:

• Change lines 58 and 68 to use app.language.__languages instead of app.language.languages and set the default value of app.language.__languages to [] instead of None. I don't think this is a good idea, though.
• Just add new app.language.languages variable with default value []. Short solution, not sure if the best.

What do you think? I'm missing something? If you tell me one of those is OK I'll open a PR.
Thank you

I also have the same problem. After [polyglot_data] Downloading package transliteration2.vi to nothing is happening.

I tried to copy packages from my old server where everything worked, but now I get Cannot update models (normal if you're offline): module 'app.language' has no attribute 'languages'

I tried this one and when i execute the python main.py nothing is happening.

i change the line 58 and 68 on init.py file
then change the None to [] and add languages = [] on languages.py

Has there been any progress on this? I am having the same error did the same thing and it did not work...

This issue seems to still be here (unless anyone has found another fix?), neither of the attempted solutions above work for me.

I have the same error message however the api works correctly.

$ python3 --version
Python 3.10.6

$ pip --version
pip 22.2.2 from /home/dingedi/.local/lib/python3.10/site-packages/pip (python 3.10)

$ libretranslate --load-only es,en,fr --disable-web-ui
Cannot update models (normal if you're offline): module 'app.language' has no attribute 'languages'

Do you mean that even with the error, it still processes requests? Does it translate even with that or is it just that the api server boots up?

[dingedi]

The api works fully even with this error on my side, the message must be irrelevant but I'll look into detail when I have time.

I'm also receiving this error, any progress on it?

Web UI works but I receive the error when trying to translate :
Cannot translate text: 'NoneType' object has no attribute 'translate'

If I dismiss the error I get the following: Error while calling /translate

I can't seem to reproduce it on my machine:

[piero:~] [test] $ python3 --version
Python 3.10.8
[piero:~] [test] $ pip --version
pip 22.3 from /home/piero/test/lib/python3.10/site-packages/pip (python 3.10)
[piero:~] [test] $ libretranslate --load-only es,en,fr --disable-web-ui

I suspect these issues have been fixed since I can't reproduce them with the latest version. If the issues persist, feel free to re-open this? 🙏
