Hey @agemagician! 
Thanks for pointing out great resources for this task. 
I noticed that the paper CodeTrans as well as the Git Commit Message Generator model available on HuggingFace Hub is only trained for Java.
I think since Java and Python have fundamentally different languages with different synatctical structure and semantics, fine-tuning that model may not yeild the best results. Though I would not mind trying at all and comparing the results, if we have time.
