UnicodeEncodeError: 'latin-1' codec can't encode characters when logging multiple runs

I am trying to log multiple runs from a single script, as described in the API docs using wandb.init(reinit=True) and run.finish(). It gives a strange error that I do not understand, it seems to be output related, but it only appears at the 2nd iteration of the following loop. The first run is logged correctly to w&b and is also closed without an error.

for validation_partition in all_ids:
        run = wandb.init(reinit=True, name=f'Val{validation_partition}')
        logger.info('Initialized new w&b run.')
        #call main
        setattr(args, 'experiment_name', f'crossval_{test_partition}_{validation_partition}_{time.strftime("%Y-%m-%d-%H-%M",time.gmtime())}')
        best_mcc_det, best_mcc_cs = main_training_loop(args)
        result_list_det.append(best_mcc_det)
        result_list_cs.append(best_mcc_cs)
        logger.info(f'partition {validation_partition}: MCC Detection {best_mcc_det}, MCC CS {best_mcc_cs}')

        run.finish()
        logger.info(f'Finished partition {validation_partition}.')

This is an issue with your terminal not supporting UTF8 characters in our output. We should detect this case, but in the meantime, setting the following in your terminal should fix this:

export LANG=C.UTF-8

You can add this to your ~/.profile or ~/.bash_rc if you’re on linux or mac. What OS are you guys using?
