DataRecord Tutorial error raised by xarray module when passing axis to Dataset through the calc_aggregate_value method

[sebastien-lenard]

In the DataRecord Tutorial, an error is raised in cell 16, when running:

mean_size = dr_2.calc_aggregate_value(func=np.mean,
data_variable='boulder_size')

Error message from the xarray module:
passing 'axis' to Dataset reduce methods is ambiguous. Please use 'dim' instead.

@sebastien-lenard This was fixed with landlab/landlab#1300. Instead of using np.mean, you should use xr.Dataset.mean.

The latest version of the tutorials are in the main landlab repository, the notebooks in this repository are no longer maintained. Were you directed here through a link in our documentation or did you just find it on your own?

[sebastien-lenard]

Actually, the unmaintained notebooks are still available through binder link in this page:
https://landlab.readthedocs.io/en/master/user_guide/tutorials.html

I also run these notebooks on the jupyterhub by cloning landlab/tutorials. So should I directly clone landlab on the Jupyterhub?

Thank you

Ah, thanks @sebastien-lenard. We will have to fix that.

There is actually an open pull request, landlab/landlab#1408, that might help with this. If you don't mind being being a tester, could you have a look and give that pull request and give it a try. It's just a script that downloads the correct version of the notebooks to match your installed version of landlab. I think it should work either from the JupyterHub or from you computer.

I tested this:
curl -L https://raw.githubusercontent.com/landlab/landlab/mcflugen/fetch-notebooks-script/notebooks.py | python - v2.4.1
and this worked as expected. Should I add a comment in landlab/landlab#1408 ?

@sebastien-lenard That's great! Thank you for testing it out. No need to add a comment to the other pull request.
