QUESTION
I have trained a model using the pix2pix pytorch implementation and would like to test it.
However when I test it I get the error
...ANSWER
Answered 2021-May-26 at 11:04I think the problem here is some layer the bias=None
but in testing the model required this, you should check the code for details.
After I check your config in train and test, the norm
is different. For the code in GitHub, the norm difference may set the bias term is True or False.

QUESTION
I am trying to convert pix2pix to a pb or onnx that can run in Lens Studio. Lens studio has strict requirements for the models. I am trying to export this pytorch model to onnx using this guide provided by lens studio. The issue is the pytorch model found here uses its own base class, when in the example it uses Module.nn, and therefore doesnt have methods/variables that the torch.onnx.export
function needs to run. So far Ive run into its missing a variable called training
and a method called train
Would it be worth it to try to modify the base model, or should I try to build it from scratch using nn.Module? Is there a way to make the pix2pix model inherit from both the abstract base class and nn.module? Am I not understanding the situation? The reason why I want to do it using the lens studio tutorial is because I have gotten it to export onnx different ways but Lens Studio wont accept those for various reasons.
Also this is my first time asking a SO question (after 6 years of coding), let me know if I make any mistakes and I can correct them. Thank you.
This is the important code from the tutorial creating a pytorch model for Lens Studio:
...ANSWER
Answered 2020-Aug-06 at 22:08You can definitely have your model inherit from both the base class and torch.nn.Module
(python allows multiple inheritance). However you should take care about the conflicts if both inherited class have functions with identical names (I can see at least one : their base provide the eval
function and so to nn.module).
However since you do not need the CycleGan, and a lot of the code is compatibility with their training environment, you'd probably better just re-implement the pix2pix. Just steal the code, have it inherit from nn.Module, copy-paste useful/mandatory functions from the base class, and have everything translated into clean pytorch code. You already have the forward function (which is the only requirement for a pytorch module).
All the subnetworks they use (like the resnet blocks) seem to inherit from nn.Module
already so there is nothing to change here (double check that though)
QUESTION
I study this tutorial https://www.tensorflow.org/tutorials/generative/cyclegan and the completed model is well worked on windows. Then I convert this tf model to mlmodel, but the model's output(MultyArray) has empty shape. How do i solve this problem...? (This model's EPOCH is 1)
computer::: windows10 / tensorflow and -gpu 2.2 / tfcoreml 1.1
this is convert code
...ANSWER
Answered 2020-Jun-12 at 09:28This is usually not a problem. When you run the model, you still get a multi-array of the correct shape.
If you already know the shape, you can fill it in so that it shows up in the mlmodel file, but this is more for documentation purposes than anything else.

won't help with this.
The problem is that your file names contain colons. Colons are not allowed in Windows file names.

new here. I am trying to create a custom optimizer in PyTorch, where the backprop takes place in a meta RL policy, with the policy receiving the model parameters, and outputting the desired model parameters. However, I am seeing the above error. My models work fine on Adam and SGD, but not my optimizer.

I'm trying to download some data using a bash script in a Jupyter notebook and having some problems.

QUESTION
I am currently looking into CycleGAN and im using simontomaskarlssons github repository as my baseline. My problem arises when the training is done and I want to use the saved model to generate new samples. Here the model architecture for the loaded model are different from the initialized generator. The direct link for the saveModel function is here.
When I initialize the generator that does the translation from domain A to B the summary looks like the following (line in github). This is as expected since my input image is (140,140,1) and I am expecting an output image as (140,140,1):
...ANSWER
Answered 2019-Oct-22 at 16:27When you persist your architecture using model.to_json
, the method get_config
is called so that the layer attributes are saved as well. As you are using a custom class without that method, the default value for padding is being used when you call model_from_json
.
Using the following code for ReflectionPadding2D
should solve your problem, just run the training step again and reload the model.
