[Snowball-discuss] Lithuanian stemmer in snowballstemmer Python library

[Konstantin Gavras]

Dear Olly,

I found the solution to my problem. I had the PyStemmer library
installed on my conda system as well.

This caused snowballstemmer to use PyStemmer functions, as mentioned in
the repo by shibukawa

"if *PyStemmer* is installed, |snowballstemmer.stemmer| returns
|PyStemmer|'s |Stemmer| objects. This |Stemmer| object has same methods
(|Stemmer.stemWord()|, |Stemmer.stemWords()|).".

Unfortunately, PyStemmer only supports a fraction of the snowballstemmer
languages.

Thank you very much for your effort!

Best

Konstantin
