OpenCV being in the list of Pyodide modules [0] was the biggest boon for my online teaching experience because remotely dealing with install woes (corporate proxies & cie) was a show stopper for regular Python.
I'm hoping that they will package this new version and that it will bring the new neural networks engines goodies to the no-install crowd !
