I have encountered with the same problem. Have you found out how to solve it?

[KevinQian97]

I am not sure if it's because of the version of pytorch

[KevinQian97]

I found that the code runs normally on faster-rcnn. But if I use the code of fpn, it failed. So I guess the problem happens in fpn.py, but I still can't find out why. What's more, I used this model to train my personal data, if I changed the data back to origin Voc2007, it works. That's strange. I just changed my personal data into the form of Voc2007. Here is one of my annotation file: train VIRAT_S_000000.mp4_0 C:/Users/Kevin Qian/Downloads/images/train/VIRAT_S_000000.mp4_0.jpg
