NameError: name 'exit' is not defined, tf.train

[HarishDechiraju]

Trying out an object detection video similar to this GitHub out here https://github.com/deep-diver/Soccer-Ball-Detection-YOLOv2/blob/master/YOLOv2-Train.ipynb

But when I run tf.train()

I get this error

NameError Traceback (most recent call last)

@HarishDechiraju i got the exact same error for a while in colab, the thing is while building the model using " pip3 install -e ." make sure u are doing it on same directory, dont just copy the entire directory are building it build it on the go

Hi guys, I am having the same error and I have done whar @krishna223412 said, however it is still not working.

Has someone any tip for this?

Cheers

So the problem is in /darkflow/utils/process.py. Apparently sys package has the exit() method and it is not in-built in Python(at least not in the latest version of Python 3).

So in process.py add:

from sys import exit

I did what @Debangsha1992 said but this is still not working for me... Any other ideas?
