AttributeError: 'NoneType' object has no attribute 'dtype'

When I try to make an inference by outputting the file name, I get this error.

Traceback (most recent call last):

And when I put "-o" as a folder, it gives an error saying it is a directory Sorry for the bad English, I used Google Translate

I also had this error, in my case it was because my GPU ran out of memory. I don't know if this is the case for you too, but I would recommend checking your GPU memory while doing the inference.

@alcoftTAO I don't think that's the problem here since I was using a T4

I think an error is occurring during inference as it is returning None to scipy.

If you are using the API, make sure to put this:

curl -X 'POST' \
       'http://127.0.0.1:8000/inference' \
       -H 'accept: application/json' \
       -H 'Content-Type: multipart/form-data' \
       -F 'modelpath={model.pth}' \
       -F 'input={input audio path}' \
       -o {output audio path}

Where you replace {model.pth} with the .pth file of your model, {input audio path} with the audio file you want to make the inference to and {output audio path} with the file in which you want to save it.

I don't know if it will work as I have never used the API. If it doesn't work, try creating the output audio first and try again.

I don't think this is the problem since I'm using CLI, not API

@shirounanashi could you tell me your environment?

[shirounanashi]

@Tps-F I was trying to use it on Kaggle
