Question: VAD from Microphone Streaming using ONNX model

[Newo6174]

I have combined the code from Pyaudio Microphone Streaming Examples and ONNX VAD Example with a view to deploy the VAD on my raspberry pi.

I replace the function validate() with validate_onnx

However, I have encountered this bug and I am not sure how to solve it:
[ONNXRuntimeError] : 2 : INVALID_ARGUMENT : Invalid rank for input: input Got: 1 Expected: 2 Please fix either the inputs or the model.
How should I change the type of inputs (audio_float32) to solve it?
Thanks in advance.

Please try checking the tensor size
From this error it seems that you are not feeding a 2D batch tensor, but just a 1D tensor

Add a dummy tensor to fix this issue unsqueeze(0)
Thanks for the help

In the end, is there an error with the utils, or was the error on your side?

If you want to use ONNX model in this example, then you need to add a dummy tensor.
