Enter the Matrix Case 5: Help!!

Question

On the Machine Learning course with Python I cannot pass the case 5 test. I have created some mechanisms to avoid the division by 0 but it is not that.

tp, fp, fn, tn = [int(x) for x in input().split()]
if tp+fp+fn+tn == 0:
accuracy = 0
else:
accuracy = round((tp+tn)/(tp+fp+fn+tn),4)
if tp+fp == 0:
precision = 0
else:
precision = round((tp)/(tp+fp),4)
if tp+fn == 0:
recall = 0
else:
recall = round((tp)/(tp+fn),4)
if precision + recall == 0:
f1_score = 0
else:
f1_score = round((2*precision*recall)/(precision+recall),4)

print(accuracy)
print(precision)
print(recall)
print(f1_score)

Answer 1

Use the round function only in the last e. g. print statement. That should help. Otherwise the "round errors" will add up and you get wrong numbers in the output.

Answer 2

Thanks a lot Bill!!!

Answer 3

Test case 5 in wrong
