@Bhanu_Prasad_CHINTAK the model.22.dfl.conv.weight layer is always frozen. Even when you don’t specify any layers to be frozen, this module will always show as frozen; see the code here. To be 100% honest with you, I haven’t looked into the why for this, but I wanted to let you know it is normal and expected.
Glad my explanation was helpful and thank you for marking it as solved! I think this is the first thread marked as solved since relaunching the forums
