Save to_netcdf hangs after using open_mfdataset

[emmaworthington]

Hi,
I'm using open_mfdataset to open a number of NEMO/ORCA12 files for a small region. I regrid the data using xesmf, then I want to save the regridded data using to_netcdf. However, the code just hangs while saving, and appears to be stuck in threading.wait().

I've tried adding lock=False to the open_mfdataset parameters, but it still hangs.

Any ideas? Otherwise I'll load the data separately, do the regridding and merge the regridded data manually.

Thanks

There are some open issues on this topic: https://github.com/pydata/xarray/issues?q=is%3Aissue+is%3Aopen+hangs

I never really figured it out and ended up throwing in a ds = ds.load() not nice but works (if you have enough memory).
