Have you installed torch? I suggest you pip install -r requirements.txt

I can confirm, the PackageNotFoundError usually occurs of the required packages are not installed, yet. I recommend running

pip install -r requirements.txt

in your terminal as suggested by @chhenning.

Alternatively, you can directly execute

!pip install -r https://raw.githubusercontent.com/rasbt/LLMs-from-scratch/main/requirements.txt

in a notebook cell.

Please let us know in case you are bumping into any issues with this.

I had this same issue, despite confirming torch was installed in my virtualenv (I could "import torch" from the python console). Turned out to be an issue only when running the notebook from PyCharm. Opening up the notebook using jupyter-lab directly worked fine.

Yeah, PackageNotFoundError: No package metadata was found for torch sounds like something is corrupt there, otherwise it would say ModuleNotFoundError: No module named 'torch'. Please make sure to use uv or pip when installing the packages, other packages managers like conda might lead to problems.

And after having installed new packages, please also don't forget to restart the kernel.
