[W NNPACK.cpp:80] Could not initialize NNPACK! Reason: Unsupported hardware. error message

Hey guys ,
I’am running into this error. I don’t really know if this is only one error messsage.

My OS:
Kali Linux

Pyhton version:
3.7

pytorch,pytorch-lightning, torchaudio, torchmetrics, torchvision version:
(I’ve installed pytorch, torchaudio and torchvision thru this command for cpu only
conda install pytorch==1.7.1 torchvision==0.8.2 torchaudio==0.7.2 -c pytorch, you can find this installation command on pytorch.org)

pytorch==1.7.1
pytorch-lightning==1.2.8
torchaudio==0.7.2
torchmetrics==0.2.0
torchvision==0.8.2

My error message:

/home/anaconda3/envs/speech/lib/python3.7/site-packages/torch/functional.py:516: UserWarning: stft will require the return_complex parameter be explicitly  specified in a future PyTorch release. Use return_complex=False  to preserve the current behavior or return_complex=True to return  a complex output.

[W NNPACK.cpp:80] Could not initialize NNPACK! Reason: Unsupported hardware.

After this error message is being displayed it is sort of creating an endless loop which is printing out every second a new row. So my program is being completely crashed because of this error message.

Is someone able to help me out with that or know what this error message is caused by?
Thank’s for every suggestion and help in advance:)

Double post with potential answer.
