With nkululeko since version 0.95.9 you can use google translate to translate your data automatically.

Simply set the language (default is en) in the PREDICT section and a prediction target translation like this:

[EXP]
# optional
language = de 
[PREDICT]
targets = ['translation']
# optional
target_language = en 

and then run the module:

python -m nkululeko.predict --config my_conf.ini.
