open_mfdataset not working as expected with rasterio engine?

[pstefa1707]

As the title says, using open_dataset with the engine="rasterio" kwarg works as expected.

However, using open_mfdataset throws a FileNotFoundError. Note my raster datasets are on s3 and are gunzipped.

Is there something I am doing wrong? thanks for the help!

Edit:
Interesting, if I add the "chunks" parameter to open_dataset I will encounter the same FileNotFoundError

Have the same problem. Did you find a solution?

Unfortunately cannot remember :/

Since you're using GDAL paths, for this particular case you can create a GDAL VRT and open that:

!gdalbuildvrt -separate stack.vrt {vsipath1} {vsipath2} 
ds = xr.open_dataset('stack.vrt', engine='rasterio')

But yes, you're right it is a bit confusing that open_dataset works with a vsipath but open_mfdataset does not. Seems like the logic for figuring out if the string is a local or remote path is slightly different from the full traceback:

File ~/miniforge3/envs/xarray/lib/python3.11/site-packages/xarray/backends/api.py:230, in _get_mtime(filename_or_obj)
    227     path = None
    229 if path and not is_remote_uri(path):
--> 230     mtime = os.path.getmtime(os.path.expanduser(filename_or_obj))
    232 return mtime

File <frozen genericpath>:55, in getmtime(filename)

FileNotFoundError: [Errno 2] No such file or directory:  ...
