Can you provide more information so I can try to reproduce your problem?

@svpino
This is a division by Zero error. on line 121
precision = float(confusion_matrix[id, id] / total_predicted)
If you fix the division by zero, this should solve the problem
if total_predicted == 0: precision = 0.0 else: precision = float(confusion_matrix[id, id] / total_predicted)

Feel free to send a Pull request. I'll review and merge it. Thanks! svpino.

Hi @svpino if i have ground truth and prediction value both in txt file then how can i used your repo? can you please explained me. Help is deep appreciate
