You need to install netcdf4-python, e.g., conda install netcdf4.

Hi @shoyer, I'm using v0.11.2 (also tried v0.11.3), but I am unable to open my NC file. I get this same error and asks me to install netcdf4, which is already installed and up to date. I could open the before I had upgraded xarray to v0.11.3. Now, even back with the old version, I am unable to open it. As I'm still a beginner, I am unable to figure out what exactly the problem is. Thanks in advance.

That error message is from SciPy. In principle, we could definitely inspect the first few bytes of the file and detect whether we have an appropriate read library install.

Should we close this issue? is not a valid NetCDF 3 file is the best xarray can do I guess, since the error comes from scipy.

I got similar errors with xarray 0.8.2. Any solution for this error? Just use import netCDF4? (I can read the nc file in R)

Cool! You saved my time! Thank you!

I just downloaded an nc file from noaa's esrl, and tried to read it using xarray, but it gave me the error message you mentioned above.
