Fix to torch_inferencer pre_process trying to use 'to(device)' on a n…umpy istance with broken shape

📝 Description

• With 1.0.0 the torch inferencer is broken, when working on 501a for example, if we convert the export and inferencer of the model to the TorchInferencer we will get broken result caused by doing numpy.to(device) in the pre_process of the inferencer. Being .to(device) a tensor method it is not possible to be working.
  Provided the fix by making a .transpose of the ndarray coming in and exporting the result with torch.from_numpy(ndarray).to(device) instead of ndarray.to(device)

On my fork on branch 501a_torch_fix can be found the .ipynb with the implementation on the cubes training/inference with OpenVino but also with the TorchInferencer

Welcome to the community, @Sbaffinator98! Thanks a lot for your contribution!

I'll be running the tests now, and we will be reviewing your PR shortly. Thanks again!

Hi @Sbaffinator98, thank you for addressing this. I've added some suggestions to fix the code-quality checks. If you want to re-produce it on your side, you could do the following from your terminal:

pip install pre-commit
pre-commit run -a

Hello i saw that you guys commited some clean-code. I see that is still failing the checks. I dont see any torch_inferencer related issue. What should i do further?

The tests are failing for some reason here

I'll check why they fail
