iodide-project / pyodide-demo Goto Github PK

I worried that this was a bit out of date.

One of my two demos fails. Turns out that this repository is missing micropip.

I am offering a class on Pyodide tonight.
https://www.meetup.com/Hackerspace-Silesia/events/261431579/

I will just tell them that the current release does not yet include microip.

when trying to run this from a website, I'm starting to get the following errors:

abort("abort(\"Assertion failed: undefined\"). Build with -s ASSERTIONS=1 for more info."). Build with -s ASSERTIONS=1 for more info.

That's the only message I get, the code, you can find it here.

This is what I did

1. I cloned this repository
2. I made it public through github pages in order for github to host the files with proper headers
3. I request it as seen in the jsfiddle

The error seems triggered by line 3833 of pyodide.asm.js
if (chunkIndex < compressedData.successes.length-1) assert(originalSize === LZ4.CHUNK_SIZE); // all but the last chunk must be full-size
The sizes differ

The arguments called are these

I also managed to get some content from the buffer

Which seems the content of builtins.py

This repo seems to require both git-lfs and then a username and password to https://1fd8fb2d-3267-4664-afca-dae42e7e5b64.netlify.com If you ignore this the data files aren't fetched and they don't seem to work.

I am the guy about to teach a class on Iodide and Pyodide.

As I have been working through the course assignments, I have come across a number of small glitches in Iodide. Not good. What to do?

The jewel in the crown is really Pyodide. All those highly used libraries, now running in the browser.

So I put together a single web page that calls Pyodide. The version under Iodide was not working. It was calling subroutines on some other website with a CORS violation.

Installing using run_docker. Who knows how long that will take. You may want to mention how long that takes too compile. Could be days for all i know.

Installing from this repository was so easy. 5 minutes I was up and running.

After banging my head against CORS for most of he day, what a pleasure.

So for end users this is a great starting point. Here is my advice.

Add a few more words of comments to this repository. Which version is it?

Mention it in the pyodide repository.

Somewhere in the distant past, I got an email about release 0.12 I think. Just download the tar ball. Now I cannot find it. Good if that were also mentioned in the Pyodide docs. Under Installation for end users.

Hope that feedback all helps.
