nbviewer equivalent?

https://marimo.app/<gh-url>

this does also try to run it, so works only for wasm compatible notebooks

How do I know that a python package has support for wasm? Any list maintained.

For our WASM x Pyodide powered playground (marimo.app):

All packages that have pure Python wheels on PyPi + these packages: https://pyodide.org/en/stable/usage/packages-in-pyodide.html

hmm... my notebook won't run on WASM, is there a way to just view it?

If your notebook uses libraries that do not lie in the link posted above (or do not have pure PyPi wheels), then you would only need to run it locally.

Are you using torch or TensorFlow?

I'm using this: https://github.com/heiner/nle

Yeah, this doesn't run on the WASM-playground.
You can preview it by:

• Hosting it on HuggingFace spaces - recommended (we have an app template where you can modify the requirements.txt file to include the libraries that you use).
• Running it locally.

any convenient way I can publish and share the results?

I'd say HuggingFace spaces is a pretty convenient way of publishing and sharing results (given your need for custom libraries).
