I am somewhat new to using Tensorflow and learn to use it from a C# application. I am trying to convert a simple LSTM Python example ([login to view URL]) that works very well on my machine in Python using the GPU. In my C# implementation, I have hard coded the input data to simplify the process. The data is identical in both the Python example and my code. However, when I try to build it in .NET (Visual Studio 2022), it crashes when the fit() method is encountered. First, the input_shape argument is not available in the LSTM constructor within .NET. So, the obvious thing to do would be to add an InputLayer instead. I have done this in the Python example code and it works fine. However, when I try to use the InputLayer in .NET, I get a completely different error than I am getting below. It seems like something rather screwy is going on that is not easily found in the documentation. I am absolutely baffled and have spent more time on this that virtually any other program error in my past. For the .NET application, I have the following 3 Nuget libraries currently added to the project...
[login to view URL] (0.4.0)
[login to view URL] (0.70.1)
I am including files containing the slightly changed python code (that runs fine) from the online example as well as my C# program code for debugging. Again, here is the link to the online example ([login to view URL]).
Here is the error I get when the fit() method is encountered but I cannot get the InputLayer to work either.
