Hi @Pkaps25 thanks for this, is it ready to review? We should add at least one test for the new argument in Daf3D however.

Hi @Pkaps25 thanks for this, is it ready to review? We should add at least one test for the new argument in Daf3D however.

Daf3D doesn't currently have a norm parameter and it looks like adding that in might be tricky since certain parts of the network expect group norm and others use ResNet's batch norm. I'd like to avoid adding that param in this PR, so short of that, would the existing tests cover my change?

Hi @Pkaps25, after we discussed from the dev meeting. One thing I overlooked in this PR is whether the change of the name of act will affect the weights loading of the original model, can you help check that, if so, maybe we need to revert the name change for the variable and add an alias.

Thanks!

Ah, nice catch. I will take a look.

Hi @KumoLiu, I trained ResNet with latest MONAI and loaded the model state using my branch. The model loaded successfully, had the same layers, and a forward pass with a random input produced the same result on both branches. Let me know if that's a sufficient check and if we need to add tests for this compatibility in the future

Thanks to the quick verification, and make sense it works since the activation function usually has no parameters to learn in the neural network. I guess we don't need to add a test for this. But if the norm layer name changed, it should be worth to add the test. What do you think? cc @ericspod

Agreed that if the name changes we should add that test, but I don't change the name in this PR.

This looks good then, I thought that a layer with no parameters wouldn't show up in the state dict but it's best to double check.
