gdal.Grid() prototype is
def Grid(destName, srcDS, **kwargs):
""" Create raster from the scattered data.
Arguments are :
destName --- Output dataset name
srcDS --- a Dataset object or a filename
Keyword arguments are :
options --- return of gdal.GridOptions(), string or array of strings
other keywords arguments of gdal.GridOptions()
If options is provided as a gdal.GridOptions() object, other keywords
are ignored. """
So the first argument must be a filename, not a dataset. Only a few utilities
accept updating an existing dataset. gdal.Grid() will generate a new output
