NameError: name 'preds' is not defined
Closed this issue · 6 comments
Hello Omar Ayman,
I find this Project very interesting so I tried it. but when the model does not detect any face then line 53 thoughts error because the 'preds' is defined inside the if condition.
Thank You :-)
Hey man,
this error appears sometimes and i can't find a reason why is this error raising but what i did is that whenever it appears i run the script again and it worked, stupid solution till i find what really causing it.
I'm exactly the same, but as much as I run the script does not work: this is my log:

Add a line "else: continue" after the condition code "if len(faces) > 0:", then run the script and it will work.
Python code line Structure error causing this problem. the solution for this is to manage the for loop in a structured way so that it will able to read 'preds'.
