FPG Neck in TOOD

[UnglvKitDe]

Hi,
I'm trying to replace the FPN neck with the FPG neck in the TOOD method. For this, I use the FPG config from here and replace it with the neck in the base config of TOOD (here). Unfortunately, I get the following error. It seems that the resolution of the channel fusion is not correct. What am I doing wrong?

File "~/mmdetection/mmdet/models/necks/fpg.py", line 331, in fuse
    out = out + item
RuntimeError: The size of tensor a (23) must match the size of tensor b (24) at non-singleton dimension 2

Thank you!
