Hi!
I am training my own model on Ubuntu as described in TUTORIAL : How I trained a specific french model to control my robot
However, I get an error:
WARNING: libdeepspeech failed to load, resorting to deprecated code
Refer to README.md for instructions on installing libdeepspeech

If I understood correctly, some characters are not present in the dirctionary. But I don’t understand why as ‘o’, ‘t’, ‘l’ and other it complains about are present in alphabet.txt.
Any ideas where it could go wrong?
