ZeroDivisionError:float division by zero

[annni1]

file:util.py function:average_precision() question1:The problem of ZeroDiVisionError:float Division by Zero often occurs in the function that calculates the average precision of each class in the util.py file.Maybe because pos_count is always zero.The program did not perform +1 operation. How to solve excuse me? question2:If label==1 was found in two places in the function average_precision() code. Is there an error here?
