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

Posted by Franco Otaola at July 06. 2021

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

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>

HTH

Posted by Franco Otaola at July 07. 2021

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.
