ZeroDivisionError: division by zero

[Psycho-9]

when i run. py, some errors occurred in training.py：

File "train.py", line 106, in
eval_loss, eval_word_score, eval_expRate = eval(params, model, epoch, loader)
File "/home/SAM/training.py", line 192, in eval
return loss_meter.mean, word_right / length, exp_right / cal_num
ZeroDivisionError: division by zero

I found these four parameters: word_right, length, exp_right, cal_num are all 0

Check if your evaluation data configuration is correct. Debug your loader variable to ensure it meets expectations.
