UnicodeEncodeError in progress bar

[Hrovatin]

Occasionally I get the below error during training when I run the below code.
Version: scArches-0.1.2

network.train(adata,
              n_epochs=params['n_epochs'],
              batch_size=params['batch_size'], 
              condition_key='study_sample',
              save=True,
              retrain=True
             )

Traceback (most recent call last):

@Hrovatin should be fixed now.
