In my experience it comes from a g.remove call that tries to remove a file
that doesn't exist. So generally, testing for its existence before removing
avoids the warning.
Also i.colors.enhance suffers from that.
Do we have any "best practice" example for that in an existing core script?
Would be good to have a 'best practice' example. I have used before
something like:
rast = 'my_raster'
cf = grass.find_file(name=rast, element = 'cell',
mapset=grass.gisenv()['MAPSET'])
if not cf['fullname'] == '':
grass.run_command("g.remove", type="raster", name=rast, quiet=True)
But I guess there are better ways to do this?
P.s. in the find_file example above, is it sufficient to use as
'element' 'cell', i.e., does that also find fcell and cellhd layers?
