issue in render own model

[Edw2n]

I'm trying to follow this link [https://github.com/tensorflow/lucid/wiki/Importing-Models-into-Lucid]

And I have error in feature visualization of a layer with lucid render.render_vis(model, "Conv2D_3:0")

What is the proper parameter in my case?

I checked my node name with this code

for node in model.graph_def.node:
      print(node.name)

And results are below.

Const
Variable
Variable_1
Variable_2
Variable_3
Variable_4
Variable_5
Variable_6
Variable_7
Variable_8
Variable_9
Variable_10
Variable_11
Conv2D_3

Relu_5
MaxPool_3
Conv2D_4

Could you help me how can I solve this problem? :)

What error do you get when you call render?

@colah The error message is as follows:

Attempted to map inputs that were not found in graph_def: [input:0]

When you exported your model, you had to declare what the name of the input node to your model was. It appears that you may have made an error when doing so, and that the name you gave doens't exist in the model.

@colah , Thanks to your answer, I solved the problem. However, I have one more problem in rendering my model.

Here is my error message

The link below is the colab notebook where the problem occurred. https://colab.research.google.com/drive/1UPtYvjM_qurK1SwkfNa-4cekb07Nz93-?usp=sharing

And also, I attached another colab notebook about building own model, so please refer to it if necessary. https://colab.research.google.com/drive/1CSRftnEDQiyXIlMwWrfWNgHQcdvUPCtH?usp=sharing

How can I solve this part?

[colah]

When you run feature visualization, you optimize an image of size set by the argument param_f. Some models are incompatible with certain input sizes. Try doing something like:

render.render_vis(model, "conv2d_2/convolution:3", 
                               param_f=lambda: param.image(MODEL_INPUT_WIDTH))

hello, have you solved this problem?

[YangLiji]

When you run feature visualization, you optimize an image of size set by the argument param_f. Some models are incompatible with certain input sizes. Try doing something like:

render.render_vis(model, "conv2d_2/convolution:3", 
                               param_f=lambda: param.image(MODEL_INPUT_WIDTH))

hello, I try this, but it doesn't work.

paramf = lambda: param.image(128) = render.render_vis(model, "73/BiasAdd:2", param_f)
