Problem with TauDEM PitRemove

[José Manuel Muñoz Guijarro]

Dear all,

I updated QSWAT recently from QSWAT 1.9 for QGIS 2.6.1 to QSWAT3 for QGIS 3.10, and now, when I try to create the streams or the watershed from a DEM file I get this error:

------------------- TauDEM command: -------------------

C:\Program Files\Microsoft MPI\Bin\mpiexec.exe -n 1 C:\SWAT\SWATEditor\TauDEM5Bin\PitRemove -z D:\Valdenoches - Hidrología\swat\arroyo\Source\arroyo.tif -fel D:\Valdenoches - Hidrología\swat\arroyo\Source\arroyofel.tif

" ERROR: unable to allocate launching block

*** Problem with TauDEM PitRemove: please examine output above. *** "

I tried to uninstall and re-install, I searched in the forum for similar problems but I have not been able to solve it with the solutions I found and I could apply (I also tried to download TauDEM executable in https://drive.google.com/file/d/0B852HLR87YyVdmRXX3JDNi1yX28/view?usp=drive_web but the file doesn't exist).

I also tried to go back and re-install QGIS 2.6.1 and QSWAT 1.9 (in March, last time I used QSWAT, it worked fine), but now I get this error message:

" An error has occured while executing Python code:

For your knowledge in case it is important these are my OS and current software characteristics:

OS

64 bit OS (processor x64). I  updated recently Windows 10 to Windows 10 version 2004.

Dear José,

The second problem is easily solved, I think. I believe it is caused by
the non-ASCII character in the path: looks like the í in Hidrología.

The first problem I have not seen before. It is a problem with MPI
rather than QSWAT, and suggestions on the web include not having
non-ASCII characters in the path to where it is being run. So this may
perhaps be fixed in the same way.

If this does not solve the first problem, try running without MPI. You
seem to have set the number of processes to 1, so you would not really
be using it in any case. Set the number of processes to 0 and MPI will
not be run.

Dear Chris,

Thank you very much.

Yes, the problem was the "í" in "Hidrología", I changed to "Hidrologia" and the errors disappeared in both cases, for QSWAT3 and for QSWAT 1.9, independently of to have set the number of processes to 1 or 0 (I tried both cases).

Thank you, thank you very much again. And also for the speed of the answer.

Well, nice to meet you and have a nice day.

Yours sincerely,

José Manuel Muñoz Guijarro
