Hi I'm trying to convert darknet Yolov4-tiny weights to tensorflow weights by running save-model.py script. but I'm facing the following error:

Traceback (most recent call last):
  File "save_model.py", line 58, in <module>

any idea what's causing this and how to fix it?

Using tensorflow 2 solved the problem 🎉
