Hi, thanks for your code.
I try to implement NAS-FPN in pytorch, but there seems to be some errors with my BN layer (Both 1-stage(RetinaNeet) / 2-stage). I freeze the BN layer in r50 backbone, fine-tune the BN in NAS-FPN (initialized with weight=1 bias=0), am I right?
The log is like this, training seems OK, but eval is always 0 (0.001).
