There is a probelm when I run my data

There is still probelm when I tried architecture for MNIST in models_def:

I think that It may be my data is three-channel RGB data. I found FRGC is the three-channel RGB data. Then I resize my data to 32323. But there is still trouble when I tried architecture for FRGC:

Do you know how to do? Or can you teach me how to build my network architecture. Especially, how to choose the parameters in the model_def? For example, how to choose the parameters of nInputPlanes, nOutputPlanes, nn.View, nn.Linear, nn.Normalize in the model_def?

I am also stuck at this point, @jwyang can you put some guideline on how to create network architecture please? Thanks
