Having problems loading a ".nc" file

[AvitayGT]

Hello,

I have a dataset of .nc format which contains the following variables:

When trying to load the file, I get the following error.
What can be done to avoid this error and to successfully load the dataset? I guess I need to change the variable name somehow so it doesn't share the same name with one of its dimensions anymore, but I don't know how to gain access to the dataset's variables' names.

unfortunately, this is not possible with xarray, yet (see #2368). You will have to use the netCDF4 library (or any other netcdf reading library, or the ncrename executable) to rename the conflicting variables:

In [1]: import netCDF4
   ...: import xarray as xr
   ...: 
   ...: # create the file
   ...: with netCDF4.Dataset("test.nc", mode="w") as nc:
   ...:     nc.createDimension("time", size=1)
   ...:     nc.createDimension("lat", size=2)
   ...:     nc.createDimension("lon", size=2)
   ...: 
   ...:     nc.createVariable("lon", "float64", dimensions=("time", "lat", "lon"))
   ...:     nc.variables["lon"][:] = [[[0, 1], [2, 3]]]
   ...: 
   ...: # fails
   ...: #xr.open_dataset("test.nc")
   ...: 
   ...: # rename variables
   ...: with netCDF4.Dataset("test.nc", mode="r+") as nc:
   ...:     display(nc)
   ...: 
   ...:     nc.renameVariable("lon", "lon_")
   ...:     display(nc)
   ...: 
   ...: with xr.open_dataset("test.nc") as ds:
   ...:     display(ds)

Thank you very much! You helped me a lot.
