nctoolkit isn't compatible with cdo 2.0.0 or above

[shiv3679]

Is there any workaround where I can use nctoolkit with cdo version 2.0.4.

[robertjwilson]

A workaround would be to clone the github repository and then make a tweak to stop nctoolkit from checking the CDO version.

So

git clone https://github.com/pmlmodelling/nctoolkit.git

Then

cd nctoolkit

You will then need to open nctoolkit/utils.py

Then delete the line with validate_version()

That's the line that checks which version of CDO is on the system, and it will throw an error if it's 2.0.4.

Then

pip install .

to install from source.

nctoolkit will work fine for CDO versions 2.05 and above. It currently throws an error because of a couple of bugs in CDO 2.0.4 that were causing knock on bugs in nctoolkit.

You will need to specify what is causing the problem. Does my solution not work?

I followed the solution you suggested but it does not work.
This is the error message I got:
Reg_Cor - Jupyter Notebook.pdf

[robertjwilson]

I should have typed ‘nctoolkit/init.py’ in my original reply. Open that in the dev version and remove validate version and then reinstall

[Gyuknj]

Installed!

I have done the correlation with easy, thanks to your script on Github!

How can I do the regression?

Good to see this issue resolved. I will close it. If you have another question please raise it separately.
