freeze_bn

[JNNNNYao]

Hi, thanks for providing this great work!!

It seems that in the implementation of DeepLab with ResNet101, no matter freeze_bn is true or false it will call self._freeze_bn so the BN will be fixed. Should line 196 be commented out?

da-sac/models/deeplabv2.py

Lines 190 to 196 in b6f0a90

	# fixing BN of the backbone
	if freeze_bn:
	print("DeepLabv2/ResNet-101: Fixing BN")
	self._freeze_bn(self)
	else:
	print("DeepLabv2/ResNet-101: Training BN")
	self._freeze_bn(self)

Thanks:)

Hi Matthew,

thanks a lot for pointing this out, you're right this is incorrect. I seem to have introduced this bug when merging branches for code release (I had slightly different versions of the code for ABN training and training with augmentation consistency), so the reported numbers are luckily not affected. Thanks again!

Best,
Nikita
