[SOLVED] Detectron2 Checkpoint not found

Detectron2 Checkpoint not found

I've been getting an error like this since last night. I trained 5 models, there was no problem. Then there was such a problem. How to resolve it?

AssertionError                            Traceback (most recent call last)

Solution

For now, I found a manual solution. I downloaded the model from the link and saved it to my drive profile. Then I copied the model from the drive profile to the output file and made changes to the code below.

cfg.MODEL.WEIGHTS = "/content/output/model_final_68b088.pkl"

Maybe there is a better solution but I don't know. I think there is a problem in accessing the model file in the link.
