Evaluate yolo v3 tiny

[rzese]

Hi all, I am trying to run the file eval.py on the COCO2017 dataset. I have run the script to convert the annotations and I thought that I had set all the files correctly. However, when I try to run eval.py using the yolov3-tiny network, which is the default one for this tutorial, I get the following error

Traceback (most recent call last):

What could I have done wrong?

Thank you in advance

@rzese which file do you use for --anchors_path? yolov3-tiny should pick configs/tiny_yolo3_anchors.txt

[rzese]

Sorry, my bad. I had not seen that file. Using tiny_yolo3_anchors.txt it works fine.
