Here I build the current PyTensor source as a pure-Python wheel and deploy an executable JupyterLite notebook using xeus-python, Numba, and llvmlite from emscripten-forge.

The demonstration is adapted from PyTensor’s existing introduction notebook and compiles the same symbolic expression with mode="NUMBA", now running entirely in the browser. The workflow builds the site for every pull request and deploys it to GitHub Pages from main.

Closing and reopening to see if the CI enables.

Once this PR is merged, could you please enable GitHub Pages under Settings → Pages and select GitHub Actions as the deployment source?

The workflow will then deploy the JupyterLite site from main. Once complete, it should be available at:
"https://pymc-devs.github.io/pytensor/"

Can we add it to the docs instead of as a github page?
