Certificate issues - possible solution

[jeremygibbonsal]

Hi Ed,

Thanks for the great content.

As I am following this course on a corporate laptop with various security tools on it - and particularly ZScaler which filters web content and perfoms TLS decryption - I encountered the dreaded TLS certificate validation issues when executing the first notebook... and have a solution which is less drastic than completely disabling certificate validation per your diagnostic notebook.

Specifically, I added "pip_system_certs>=5.2.0" to the list of packages in pyproject.toml. This package essentially allows various Python components to leverage the Windows certificate stores to validate TLS certs / HTTPS connexions. In cases like mine this helps because the ZScaler certificate is present in the Windows cert store, but not visible to Python out-of-the-box. I then did a "uv sync" and the week 1 notebook immediately started working with no other changes.

Thanks,

I think this is covered in the FAQ but I've added an explicit note about it - thanks so much
