No detections while using model weights from training custom dataset

[cooldecola]

Hi, had a custom dataset that I trained using Detectron2 and was happy with the AP value, now I'm trying to use the "model_final.pth" to run inference on a video, however whenever I do this I get no detections on any of the frames. However when I use pretrained weights from detectron2's model zoo it works. Why is this?

This is how I'm loading the weights:
cfg.MODEL.WEIGHTS = ("model_final.pth")

I think the syntax is

cfg.MODEL.WEIGHTS = "model_final.pth"

not

cfg.MODEL.WEIGHTS = ("model_final.pth")

Did this work?
