Issues replicating time series analysis with Transformers

I am trying to replicate one-to-one the univariate time series analysis using the vanilla Transformer provided in this notebook:

I am using Jupyter notebook in VS Code, Python 3.10.9 and Jupyter 6.5.4 in a virtual environment.

Everything runs smoothly until the forward pass, where I get the following error (full traceback):

TypeError: expected Tensor as element 1 in argument 0, but got NoneType

I am fairly new to Transformers (and Python in general) but I suspect the issue lies in relation to the error:

[Errno 2] No such file or directory:
‘/var/folders/vq/0s913kg97lv155_r9j2g9qxm0000gn/T/ipykernel_63681/2795771002.py’

I checked the directory, and indeed no such file exists. I tried upgrading ipykernel without success. There seems to be no issues loading all required libraries in their newest versions.

Any suggestions as to what the issue might be?

I found the error for any other user who might run into this issue:
Follow the documentation on Installation and remember to brew install cmake and pkg-config when running on an M1 :smile:
