Hi all!
while running run_placesCNN_basic.py, this error comes up
Traceback (most recent call last):

Any advice? Thanks!

This error may caused by your fragmentary model.

i solved this problem by re-downloading the model

i solved this problem by re-downloading the model

model = torchvision.models.detection.maskrcnn_resnet50_fpn(pretrained=(True))
how to re-downloading the model?

Check your torch version. I solved this by upgrading my torch to 1.8.2. It is said in README that the version of torch needs to be higher than 1.3.0.
