@njss this isn't supported unfortunately-- it looks like you found the right issue: iodide-project/iodide#2551 -- note that iodide isn't under active development at the moment
@subwaymatch maybe you could help on that one iodide-project/pyodide#97 i think there's a python only solution to it but i haven't even started yet https://github.com/pmp-p/x-python/tree/wasm-runtime

I created a project called wc-code that uses pyodide
here is a minimal example

<!DOCTYPE html>
<head>
<script type="module" src="https://cdn.jsdelivr.net/gh/vanillawc/wc-code@1.0.3/src/wc-code.js"></script>
</head>
<body>
<wc-code mode="python">
<script type="wc-content">
a = 1
b = 1
print(a+b)
</script>
</wc-code>
</body>
essentially it'll let you run the code in the browser via pyodide
I've been using this in my website, for example here https://adityashankar.xyz/study/python/introduction-to-python
specifically my project wants a newer version of pyodide; I can change it manually but I also see no reason not to update it upstream
example :
<!DOCTYPE html>
<head>
<script type="module" src="https://cdn.jsdelivr.net/gh/vanillawc/wc-code@1.0.3/src/wc-code.js"></script>
</head>
<body>
<wc-code mode="python">
<script type="wc-content">
i = 0
while i<10:
print(f"currently at : {i}")
i += 1
</script>
</wc-code>
</body>

I think this is going to be very relevant to the people who land up in this repository
a docs/ecosystem.md (unless you think of a better name) that is linked in index.rst under the "Project" section. With a title 'Related packages' and subtitle "Projects using Pyodide"
This could also be the occasion to mention/thank the projects we rely on and in particular emscripten
or maybe
docs/related-projects.md would be better
Hey, people, I'm a pyodide beginner. I'm trying to compile it and after it compiles a lot of modules it gives me this:
sed -i -e 's/\-undefined dynamic_lookup//' /home/anthony/learn-webassembly/pyodide/cpython/build/Python-3.8.2/Lib/_sysconfigdata__emscripten_.py
sed: can't read /home/anthony/learn-webassembly/pyodide/cpython/build/Python-3.8.2/Lib/_sysconfigdata__emscripten_.py: No such file or directory
make[1]: *** [Makefile:123: /home/anthony/learn-webassembly/pyodide/cpython/build/Python-3.8.2/libpython3.8.a] Error 2
make[1]: Leaving directory '/home/anthony/learn-webassembly/pyodide/cpython'
make: *** [Makefile:240: cpython/installs/python-3.8.2/lib/python3.8] Error 2
BTW, I have Python 3.8.7 installed. Is this a problem? Should I install 3.8.2 instead?
yes you need Python 3.8.2 if you install it outside of Docker. You can install it for instance with conda
Hello everyone! I'm new to Pyodide, and really interested in getting a JS websocket into my python code, however all of my attempts have failed hence I'm here. When I'm trying to achieve is to delegate a python function as an onmessage callback (that part works) and to invoke the "send" methon from python, the latter doesn't seem to be working. Should it? or am I misunderstanding some basic concept that would forbid me to achieve this?
tried sharing a queue from py->JS , tried getting the send function itself from a JS function to py, tried invoking the WebScoket.new from python (which works, but the send method doesnt)
@pmp-p yes the goal would be to integrate it in an async project of mine (have high hopes that iodide-project/pyodide#958 will be accepted soon. BUT for testing purposes I'd be happy to see even a simple callback based solution at work.
Hello @skelsec and welcome! Could you please open an issue or a StackOverflow question (using a pyodide tag) with a minimal example that you have tried? The issue with gitter is that it's not well indexed by search engines so the all detailed discussion is essentially "lost" here in the future.
Hello all! New to pyodide. When I import scipy in Chrome, it throws a ton of these "DevTools failed to load SourceMap: Could not load content for wasm://wasm/_nnls.cpython-38-x86_64-linux-gnu.wasm.map: HTTP error: status code 404, net::ERR_UNKNOWN_URL_SCHEME" errors. It doesn't do that in Firefox. Any clue as to why?
Hello @TheBosshead_twitter Please open an issue on github indicating versions of pyodide and Chrome that you are using. Ideally with a minimal reproducible example.
Hey people, I'm trying to run pyodide (I'm a beginner) on a Vue application (also a beginner). I can't figure out how (and whether) I can use pyodide with node/webpack. I tried, for example,
import { languagePluginLoader } from 'pyodide' and various other things, but nothing I've tried works.
I don't think it works at the moment, but some people are looking into it
So, when Python, numpy and pandas are all loaded, executing pyodide.runPython('import numpy') takes about 5 seconds on my system; import pandas takes about 10 seconds. (These are with Firefox; Chrome times are different but similar.)
I noticed that even in CPython the times needed to import these are non-negligible; import pandas takes 0.5 to 1 second, depending on the status of disk cache. import numpy is faster but clearly not instant (I didn't measure it).
But why the long times in pyodide?

One possibility is that we lz4 compress all files, and they are decompressed on the fly when you use them
