Check and modify the weights of a layer of an onnx model at runtime

Question

I'm using Onnx Models from ONNX Models ZOO with ONNXRuntime as a engine for inference.

I want to check and modify the weights of a convolutional layer (or any layer) of an ONNX model at runtime. This is to do it inside 'OnnxRuntime.InferenceSession.run()'. Is that possible? Did anyone do something similar?

Could be done by adding a layer before the layer I want to check and modify its weights? This new layer should do this procedure before the convolutional layer, but it would need access to the weights of the next layer.

Thanks.

Izan.
