Thanks for all the work you've done! Any chance you have a suggestion for the following error?

Most probably it’s due to a custom layer implemented in keras which is not present in tensorflow.

Hello, Thanks for your code. I was trying to convert my Keras model to .pb file , I was successfully able to convert my Keras model to .pb file. After that, using winmltools I converted it into ONNX.

Now I am trying to build an Windows ML app in .Net Core. So, while I am loading my onnx model i am getting the following error:

Type Error : Type parameter (T) bound to different types (tensor(float) and tensor(int32) in node (conv2d_transpose_4/mul).

I tried to figure out the error, I found out while using your code to convert my model from Keras to tensorflow, conv2d_transpose is in type int32 but is there a way to keep the type float.

Is there a way I can resolve this error ?

More information : Please see the 2 graphs. unet.h5 ( my pre-trained keras model ) - Here type of conv2d_transpose_4 is float32. But in converted .pb file the type of conv2d_transpose_4 is int32.

unet.h5 file

unet.pb file

@Rathna21 That is a weird behaviour; unless if you used "quantization" features of tensorflow. I have not changed the data type for any tensors in this simple conversion tool, so, this behaviour is quite unexpected.
