Dear Grass users,
I obtain this error running r.terraflow module from the python environment:
import grass.script as gs
...
gs.run_command("r.terraflow", elevation='DSM_neg', filled='DSM_neg_filled',
overwrite=True)
WARNING: Raster map <DSM_neg> is of type DCELL_TYPE -- precision may be
lost
ami_single_temp_name: G_mkstemp() failed: : No such file or directory
r.terraflow: ami_stream.cpp:93: int ami_single_temp_name(const string&, char*):

elevation=DSM_neg filled=DSM_neg_filled ended with error
Process ended with non-zero return code -6. See errors in the (error) output.
I haven't found any help looking about it on the web and I cannot understand
the reference about the missing file
ami_single_temp_name: G_mkstemp() failed: : No such file or directory
that I guess is the problem.
thanks a lot for any help.
Cheers
