TypeError when runing COSIPY on the example files

[arbindrakhadka]

When running cosipy on a newly built Anaconda on the Zhadang example, we get the error message below. Note that we did manage to install and run cosipy on previous Windows installs of Anaconda. Could this be a problem with the version of xarray or pandas?

Traceback (most recent call last):

Yes, I think it is an issue with the newest xarray version 0.19.0.

Could you install version 0.18.2 and test if it works?

[FannyBrun]

Sorry for not following on the thread. Yes we rolled back to the xarray version 0.18.2 and it worked fine. Thanks!

Can COSIPY run normally on Windows system now?

[AnsArn]

The main run can be executed on Windows systems. Only the preprocessing step to create the static file is not possible on Windows systems.
