Building packages with C/C++ extensions is still a bit tricky but you can see a list of all prebuilt packages for wasmer at https://pythonindex.wasix.org .
numpy is available there, scipy not (yet).
Wow, this is the key. If it just had python that’s not as useful but the major frameworks is the real value. Definitely going to keep an eye on this. I built a sandbox with deno for ai code generation. It works well enough but there are some use cases where python may make more sense. Nice!
