Import error when running surface_currents.ipynb on Binder

[lqgentner]

Dear all,

I discovered your notebook to learn about batch generation with xarray datasets for machine learning.
Sadly, I am not able to run the first cell in surface_currents.ipynb:

import xarray as xr

ImportError: cannot import name 'TypedDict' from 'typing' (/srv/conda/envs/notebook/lib/python3.7/typing.py)

Possible solution
The binder environment currently uses Python 3.7. Switching to Python 3.8 or newer should solve the import error.

If I can change the Python version of the Binder environment myself, I would be grateful for a hint!

Thank you,
Luis

I'm seeing this too.

@brian-rose Could you transfer this issue to the right repo?

[brian-rose]

@cmdupuis3 I don't think there's a better place for this issue, if it pertains to the Binder image for this cookbook.

Let's try modernizing the environment file in this repo and see if that gets us anywhere.

@cmdupuis3 After merging #13, there's a new Binder image running Python 3.10. The import error is gone, but some new errors are popping up farther down in the notebook. Maybe you can try running on the Binder and take a look? I don't know much about the actual contents of this cookbook.

😬 At a first glance, I believe it's a problem related to the intake library. Maybe the syntax changed or something, but I'm actually not that familiar with the library.

from intake import open_catalog
cat = open_catalog("https://raw.githubusercontent.com/pangeo-data/pangeo-datastore/master/intake-catalogs/ocean/CESM_POP.yaml")
cat['CESM_POP_hires_control']

I also tried it in python 3.12, but it seems there's also a dependency on distutils, which is deprecated in 3.12.

Interesting, I see that our Intake Cookbook is also failing. Maybe related? I'll open an issue over there.

As I noted over at ProjectPythia/intake-cookbook#33, Intake 2.0 was released in Feb 2024 and there seem to be some backwards incompatible changes. That's about as far as I can get right now.
