290572700 MDU6SXNzdWUyOTA1NzI3MDA= 1849 passing unlimited_dims to to_netcdf triggers RuntimeError: NetCDF: Invalid argument gerritholl 500246 closed 0     12 2018-01-22T18:43:23Z 2019-06-04T20:41:50Z 2019-06-04T20:41:50Z CONTRIBUTOR      

For some datafiles with properties I cannot quite reproduce, .to_netcdf leads to a RuntimeError: NetCDF: Invalid argument if and only if I pass an unlimited_dims corresponding to y. The problem is hard to reproduce. It happens to this particular dataset, but not to seemingly identical ones created from scratch. I attach sample.nc (gzipped so github would let me upload it).

``` $ cat mwe.py

!/usr/bin/env python3.6

import xarray

ds = xarray.open_dataset("sample.nc") ds.to_netcdf("sample2.nc", unlimited_dims=["y"]) $ ncdump sample.nc netcdf sample { dimensions: y = 6 ; variables: float x(y) ; x:_FillValue = NaNf ; int64 y(y) ; data:

x = 0, 0, 0, 0, 0, 0 ;

y = 0, 1, 2, 3, 4, 5 ; } $ ./mwe.py Traceback (most recent call last): File "./mwe.py", line 5, in <module> ds.to_netcdf("sample2.nc", unlimited_dims=["y"]) File "/dev/shm/gerrit/venv/stable-3.6/lib/python3.6/site-packages/xarray/core/dataset.py", line 1133, in to_netcdf unlimited_dims=unlimited_dims) File "/dev/shm/gerrit/venv/stable-3.6/lib/python3.6/site-packages/xarray/backends/api.py", line 627, in to_netcdf unlimited_dims=unlimited_dims) File "/dev/shm/gerrit/venv/stable-3.6/lib/python3.6/site-packages/xarray/core/dataset.py", line 1070, in dump_to_store unlimited_dims=unlimited_dims) File "/dev/shm/gerrit/venv/stable-3.6/lib/python3.6/site-packages/xarray/backends/common.py", line 254, in store args, kwargs) File "/dev/shm/gerrit/venv/stable-3.6/lib/python3.6/site-packages/xarray/backends/common.py", line 221, in store unlimited_dims=unlimited_dims) File "/dev/shm/gerrit/venv/stable-3.6/lib/python3.6/site-packages/xarray/backends/netCDF4_.py", line 339, in set_variables super(NetCDF4DataStore, self).set_variables(args, **kwargs) File "/dev/shm/gerrit/venv/stable-3.6/lib/python3.6/site-packages/xarray/backends/common.py", line 233, in set_variables name, v, check, unlimited_dims=unlimited_dims) File "/dev/shm/gerrit/venv/stable-3.6/lib/python3.6/site-packages/xarray/backends/netCDF4_.py", line 385, in prepare_variable fill_value=fill_value) File "netCDF4/_netCDF4.pyx", line 2437, in netCDF4._netCDF4.Dataset.createVariable File "netCDF4/_netCDF4.pyx", line 3439, in netCDF4._netCDF4.Variable.init File "netCDF4/_netCDF4.pyx", line 1638, in netCDF4._netCDF4._ensure_nc_success RuntimeError: NetCDF: Invalid argument
