ValueError: model input param must be a PyTorch, TensorFlow, or Keras-with-TensorFlow-backend model

[tphankr]

**I have the problem. I want to visualize this code, but my code had error: ValueError: model input param must be a PyTorch, TensorFlow, or Keras-with-TensorFlow-backend model. I don't know, how do I set the input number? ( I am using the pytorch tool) I did:

• [ ]

                   " import hiddenlayer as hl
                      input = torch.zeros([1, 3, 64, 64, 64])
                      model = VoxResNet()
                      hl.build_graph(model, (input))"
  

I am following this code from GitHub: https://github.com/Ryo-Ito/brain_segmentation. Please, help me, visualizer. Thank you.**

Hi @tphankr , I have got the same issue

Have you cleared it? or did you try any other visualization tool? If so please let me know.
