[Training] More Documentation on HOW to do ONNXRuntime training using c# [CSharp]

[GeorgeS2019]

Describe the issue

Please add Csharp topic and see the impact to c# users

Summary

I would like to take an Onnx model exported to e.g. HuggingPlace and do further training on it using OnnxRuntime using C# for all the workflow without needing PyTorch.

============================
With the new release, there are more information on

• OnDevice training
• Large Model training

Since these topics are listed as separates from e.g. C#
I wonder where I could learn more on using c# to do training using ONNXRuntime.

To reproduce

Onnxruntime using c# lacks information on training

See the picture above and information listed under the c#

Urgency

We are currently working out a workflow where we would like to do deep reinforcement training and save the model for inference ALL in C# in Godot 3D engine environment.

We could do inference using ONNXRUntime.

However, we would really like to START doing real time training using the ONNXRuntime framework within Godot 3D engine (.NET6 csharp)

Possible example doing OnDevice training using c#

Even the latest Bing's ChatGPT4 fails to answer this simple question if it is possible to do ONNXRuntime training using c#

Perhaps we need a restructuring of the documentation structure => to not just assisting c# users but also ChatGPT4

ONNX Runtime Training Examples

It seems there is possibly ONE example.

This does not help me to see the overview what is the decision to support Onnxruntime training using c#

[GeorgeS2019]

By searching using https://github.com/microsoft/onnxruntime/issues?q=label%3Aapi%3ACSharp, found relevant issues

• [Training] [C# API] TrainingSession ToBuffer() function returns type which is unusable #17584

Before I go further, kindly summarize if Onnxruntime training using csharp is working at all??

When will this be fixed?

We definitely need documentation on this issue!

==> is the following example working and relevant to this discussion?

@GeorgeS2019 please look at the API docs https://onnxruntime.ai/docs/api/csharp/api/Microsoft.ML.OnnxRuntime.TrainingSession.html

The overview can be found here: https://onnxruntime.ai/docs/get-started/training-on-device.html

Let me know if there are more questions.

@baijumeswani

Thanks! I will create more separate issues that I hope will cover the different implications of having this training now feasible using c#
