[SOLVED] SofaPython3 with v20.12.02 binary install on Win10

[SerkanErgunAAU]

Hello!

I just downloaded the newest binary of SOFA v20.12.02 on my Win10 machine.
I want to add SofaPython3 together with STLIB and Softrobots plugin, as they are already available in the plugin folder (but not added to plugin config file)

When I run Sofa from cmd I get the following error:

[INFO]    [SofaPython3]  Initializing with python version 3.7.9 (tags/v3.7.9:13c94747c7, Aug 17 2020, 16:30:00) [MSC v.1900 64 bit (AMD64)]

Somehow SofaPython3 tries to search for site-packages in the root directory of SOFA, in the following I added the python3 folder from SofaPython3 plugin to the root directory, which results in the following error:

[INFO] [SofaPython3] Added ‘C:/Users/xxxx/SOFA/v20.12.02/python3/site-packages’ to sys.path
Traceback (most recent call last):
File “<string>”, line 1, in <module>
ModuleNotFoundError: No module named ‘Sofa.livecoding’

Sofa will eventually launch, it recognises *.pyscn files. But when opening one of the SoftRobot demo files inclduing STLIB it says that it cannot find the module.

Hey @serkan-ergun

I am not so sure about Windows, but could you try to set up environment variable as:
– SOFA_ROOT=/path/to/SOFA
– PYTHONPATH=$SOFA_ROOT/plugins/SofaPython3/lib/python3/site-packages

Hope this helps. Else @guillaumeparan might be able to help here.

Best

Hugo

Hi,

The line [INFO] [SofaPython3] No python3 dir found in C:/Users/seergun/SOFA/v20.12.02 is an old issue that has not been cleaned yet, but it is not fatal.
Thus it is not the reason of your crash.

What happens if you open Windows Console (cmd.exe) and run python -V ?

Hope that helps,
Guillaume.

[SerkanErgunAAU]

Hi @guillaumeparan ,

thank you for your quick responses.

python -V in cmd returns:

Python 3.7.9

[SerkanErgunAAU]

Hi @hugo ,

also thanlks for your quick reply as well,

setting the variables environmentvariables (not system variables) I receive the following command window output:
(This is clearly a python error, when the path to python is not correct, I had it before I set the PYTHONPATH /PYTHONHOME to my Python 3.7 directoy correctly)

Thank you both for your efforts so far.

[Guillaume]

Could you please paste the entire log of your runSofa execution?
From your runSofa command line until the end of the crash log.

Thanks,
Guillaume.

I think I understand the issue.

Please try running runSofa -lSofaPython3 to force SofaPython3 to be loaded before any other plugin.
OR, you can also move upper the SofaPython3 line you added in plugin_list.conf (I suppose you did that).

The thing is SofaPython3 must be loaded before STLIB in order to have STLIB’s site-packages added to sys.path`.

Hope that helps,
Guillaume.

[SerkanErgunAAU]

Hi Guillaume,

huge thanks to you for your persistance into solving my issue.

As you already assumed, I placed SofaPython3 on top of all the plugins to be loaded.

Unfortunately, runSofa -l SofaPython3 produces the same error ouput.

Also I have a additional question:
What is the difference between stlib and stlib3 (the new py3scn scenes use stlib3 in their import command instead of stlib), in the plugin directory there is only a STLIB dir)?

Thank you ever so much,

Serkan

[Guillaume]

Indeed stlib3 contains a python3 version of STLIB.
It is located in STLIB/lib/python3/site-packages.

Actually you have to choose :
– If you run runSofa -lSofaPython -lSTLIB (with python2 correctly set up in your environment) you will be able to load python2 scenes which contain import stlib
– If you run runSofa -lSofaPython3 -lSTLIB (with python3 correctly set up in your environment) you will be able to load python3 scenes which contain import stlib3

Thus, if you do runSofa -lSofaPython3 -lSTLIB you CANNOT load a scene which contains import stlib because the “stlib” package is a python2 package.

If the “stlib” package is critical for you and cannot be replaced with “stlib3”, you will have to switch to SofaPython2 (and setup python2 in your environment).

Hope that helps,
Guillaume.

[SerkanErgunAAU]

So, just to fully understand the issue:

I do the following: runSofa -lSofaPython3 -lSTLIB using import stlib3

For instance I open the following file in SOFA: https://github.com/SofaDefrost/SoftRobots/blob/master/docs/tutorials/FirstSteps/details/step4.pyscn

[Guillaume]

Where did you put import stlib3?
I’m afraid you won’t be able to simply convert a scene using stlib/splib (python2) by replacing all the imports to stlib3/splib3 (python3) because, as far as I know, all stlib/splib features have not been ported to stlib3/splib3.

In your output, the line [INFO] [SofaPython3] No python3 dir found in C:/Users/seergun/SOFA/v20.12.02/plugins/STLIB is not normal.
SofaPython3 should find C:/Users/seergun/SOFA/v20.12.02/plugins/STLIB/lib/python3/site-packages.
Do you have this directory?

[SerkanErgunAAU]

pardon me, I gave you the wrong link to the file I tested:
This is the file I used for testing:
https://github.com/SofaDefrost/SoftRobots/blob/master/docs/tutorials/FirstSteps/details/sofapython3/step4.py3scn

Per default, there is no site-packages folder included in this directory:
C:/Users/seergun/SOFA/v20.12.02/plugins/STLIB/lib/python3

[Guillaume]

Ok, there is an issue with SOFA “.exe” installer, thanks for spotting that!

Could you replace your SOFA with the “.zip” version and try again?

[SerkanErgunAAU]

I downloaded the “zip” version now. STLIB apparently can be loaded now (the directoy contains a site-packages folder now)

Unfortunately I am presented with the following error

Hi Serkan,

Sorry for the delay.
I just checked and, as I suspected, the stlib3 packages are not stable yet.

Compared to stlib, a lot of assets are missing and thus a scene created with stlib cannot be used with stlib3 by simply importing stlib3 instead of stlib.
Unfortunately, it looks like that’s what has been done for step4.pyscn: the python2 scene was SoftRobots\docs\tutorials\FirstSteps\details\step4.pyscn and it was converted to SoftRobots\docs\tutorials\FirstSteps\details\sofapython3\step4.py3scn simply by importing stlib3 instead of stlib.

I simpler words: consider that scenes using stlib3 might not work.
I will definitely push for a cleaning of all those scenes for the next SOFA release.

Thus, I advise that – for now – you stay on the old (but stable) stack:
Python2.7 + SofaPython + STLIB + SoftRobots
With this stack, I successfully loaded the Python2 version of the scene you are working with: SoftRobots\docs\tutorials\FirstSteps\details\step4.pyscn

Still, if you want to stick to Python3, it would be awesome to report on this topic or on a dedicated issue the scenes that are broken, the errors you encountered, and how you fixed them (if you did).

Hope that helps,
Guillaume.

Hi Guillaume,

thank you for all the investigations. As the real issue is clearly out of scope of the initial enquiry, I will mark this topic as solved. Thanks again. I will try to post some issues that I may find on the Github link provided.

Thank you very much,

Serkan

Hey,

Did you follow the instructions at SofaPython3 readTheDocs?

I have seen this error previously when I forgot to set PYTHONHOME as a system variable.

I hope this helps.

All the best,

Serkan

[mcpalu]

You made my day!!Thanks! I had the python dir set up in the “path” system variable but not as “PYTHONHOME”. It works fine!!! Maybe it could be usefull to add this info in the docs.
Thanks!
