problem with salome 9.7 ubuntu vr in windows WSL with ubuntu 20.04

hello,

I just downloaded the last vr of salome for ubuntu and as in a ubuntu machine, i extracted with tar but when I run salome,

get the following error:

"

ERROR:salomeContext:Unexpected error:

Traceback (most recent call last):

  File "/home/otaolafr/SALOME-9.7.0-native-UB20.04-SRC/BINARIES-UB20.04/SALOME/bin/salome/salomeContext.py", line 278, in _startSalome

    import psutil

ModuleNotFoundError: No module named 'psutil'

"

PS. I know that there is a windows 10 native version, but I could not succesuflly run .py scripts from the terminal with this version. thats why I was looking to install the ubuntu vr inside wsl

best regards

Quick update, I solve this issue (not sure if it works! but at least I do not get the error) by:

copying "\home\otaolafr\SALOME-9.7.0-native-UB20.04-SRC\PROJECT\products\env_scripts\psutil.py"

to "\home\otaolafr\SALOME-9.7.0-native-UB20.04-SRC\BINARIES-UB20.04\KERNEL\bin\salome"

still I am getting an error from "/home/otaolafr/SALOME-9.7.0-native-UB20.04-SRC/salome -t -u preparingGeom.py" but clearly from the error it looks that salome is workign....
that says

usage: salome start [options] [STUDY_FILE] [PYTHON_FILE [args] [PYTHON_FILE [args]...]]

Python file arguments, if any, must be comma-separated (without blank characters) and prefixed by "args:" (without quotes), e.g. myscript.py args:arg1,arg2=val,...

runSalome: error: unrecognized arguments: -u

ERROR:salomeContext:SystemExit 2 in method _runAppli.

looks like -u was an old argument but still getting errors with -t argument only.

Hi Franco,

quoting:

". I know that there is a windows 10 native version, but I could not succesuflly run .py scripts from the terminal with this version. thats why I was looking to install the ubuntu vr inside wsl"

can you elaborate about the issue you're experiencing with running python script from terminal ?

Then, you should NOT copy psutils.py from PROJECT, since this file is aimed at compile time only of SALOME application. Instead, you need to ensure that python3-psutil is installed

Note, that you can check all missing packages as written in the README, with command:

                           ./sat config SALOME-9.7.0-native --check_system

Can you please tell which issue you're experiencing with Windows, to check if we can help here ?

Hello nabil,

thanks for the help

I excuse myself if I am missing something.

I was trying to run a python dump script with the windows vr of salome, from the WSL terminal.
I usually do this with scripts from paraview (using also the windows version)

I was using the command "/mnt/c/SALOME-9.7.0/run_salome.exe -t test9_7.py" but this opens the python3 windows, and then nothing happens. I was looking to run the code in the background,

if I open salome with the GUI, and go ->load script and choose the test9_7.py it runs correctly.

best regards

It seems that there is an issue with run_salome.exe and how it is handling extra arguments. Indeed it is aimed to be a simple SALOME launcher.

Thanks for reporting about the issue.

You can instead use the run_salome.bat, which handles consistently the number of arguments.

call run_salome.bat -t test9_7.py

Hello nabil,

with pleasure! I am not really a lot of helpfull but at least if I can help with anything I am happy.

in any case, run_salome.bat does not work either.

when I run "/mnt/c/SALOME-9.7.0/run_salome.bat -t test9_7.py"

I get:

"

Hi Franco,

you need to run run_salome.bat FROM a CMD terminal IN WINDOWS.

so open a cmd terminal, then cd to your SALOME installation folder with cd C:\SALOME-9.7.0

then run: call run_salome.bat <and your options>

hello nabil,

thanks for you useful help and recommendations!

now everything is working, 

for anyone that comes across this post might be helpful:

As I needed to run the salome script inside a bash file (and running it from the terminal in ubuntu WSL), I used the following command:

" cmd.exe /mnt/c/SALOME-9.7.0/run_salome.bat -t ./scriptPythonSalome.py "

also as a side note, to wait until the script finish,

I added the creation of a dummy file in the scriptPythonSalome.py and in the bash script a while loop that checks until it finds the dummy file.
also the python consol does not close once the script is finished, for this I added to the python script at the end:

import killSalome

killSalome.killAllPorts()

best regards.

F.
