How to use latest pyodide kernel

[kp992]

Hi,
I am using the template to run some of the lectures and the version of pandas is 1.5.3. I would like to upgrade pyodide to the latest version. How can I do that?

Hi @kp992 could you provide a link to the page where you are trying to do this so we can see better if we can help?
To be honest, most of us at TeachBooks use the sphinx-thebe extension "as-is" and adapt the packages that are imported and used by Pyodide, rather than changing Pyodide itself. You should be able to specify the pandas version without changing pyodide, for example with micropip, but it's hard to tell without an example for your use case. Here is the relevant micropip page:

https://kp992.github.io/intro-wasm-demo/main/inflation_history.html - I am trying to install pandas 2.1.4 using

%pip install "pandas==2.1.4"

which throws

ValueError: Can't find a pure Python 3 wheel for 'pandas==2.1.4'.
See: https://pyodide.org/en/stable/usage/faq.html#why-can-t-micropip-find-a-pure-python-wheel-for-a-package
You can use `await micropip.install(..., keep_going=True)` to get a list of all packages with missing wheels.
