Error precompiling CSV and SentinelArrays

New to Julia

Hi:

Trying to run the first notebook (Data) in the Julia Academy Data Science course and it fails immediately on the using CSV command, failing to precompile SentinelArrays. I’ve seen there were problems people had last year with CSV when upgrading to 1.7, but I’m running Julia 1.8.5. Any suggestions?

Are you activating the environment? It looks like a Manifest.toml is committed to github. You should try and use those exact versions.

I thought I was following the instructions to do so (with instantiate), and that seemed to use the right versions, but maybe there’s a step I’m missing with regard to “activating the environment.”

In any case, short term, the error was eliminated by updating the packages – not using the exact versions. (And the notebook is a couple of years old I now see, so it’s probably no surprise that it may now have some issues.)

Thanks!
