    Hello everybody!

    I am not well versed in setting up programs and stuff so I apologize in advance for the noob-questions that follow. Nevertheless I’d greatly appreciate your help! In the following I try to describe my proceedings and the issued errors in detail. Python 3.7 is installed on my computer that runs Windows 10.

    I installed sofa v20.12.01 from binaries (https://www.sofa-framework.org/download/) and followed the great “SOFA Training Session 2020: Introduction to SOFA” on youtube with which I managed to build my first scenes with xml.
    Since I am interested in using the SoftRobot plugin and python scripts I then did the following:
    Runsofa > edit > plugin manager > add
    And then I added:
    – C:\Users\vogts\SOFA\v20.12.01\plugins\SofaPython3\bin  SofaPython3.dll
    – C:\Users\vogts\SOFA\v20.12.01\plugins\SoftRobots\bin  SoftRobots.dll
    – C:\Users\vogts\SOFA\v20.12.01\plugins\STLIB\bin  STLIB.dll (I am actually not sure if this step was necessary, I see in the plugin manager that STLIB is located at a different path (\v20.12.01\bin) than the other two so STLIB might have already been included (?)

    I then downloaded the softrobot plugin from https://project.inria.fr/softrobot/install-get-started-2/download/ and copied ONLY the folder C:\Users\vogts \Downloads\SOFA_v20.12.02_Defrost_Win64\SOFA_v20.12.00_Win64\plugins\SoftRobots\docs into C:\Users\vogts\SOFA\v20.12.01\plugins\SoftRobots, since I couldn’t find included tutorials with the original download. Afterwards I deleted all files of this second download.

    Error A) Now when I try to open “firststeps-tuto.pyscn” from sofa > open in the FirstSteps tutorial that I added into above-mentioned folder structure, I get the following error message:

    errorA

    Error B) I also tried writing a Python file (myscript.py located where the normal xml examples are located) from scratch and opening that from within sofa (same as the one presented in the SOFA training sessions, see screenshot). The exact same error appears also with a myscript.pyscn file extension.
    myscript.py
    errorB

    Could anyone help me with these errors?
    Again I apologize for my lack of experience with setting up these things.

    Best regards

    Hi @steph,

    First of all, welcome on the SOFA forum! Here, no need to apologize for noob-looking question, we are here for this! Second, it is really great to read that the YouTube tutorials are being helpful! Note that more advanced training session can be arranged for later 😉

    NOTE: I can not access your errors / files.

    Downloading SOFA binaries from https://www.sofa-framework.org/download/ or from https://project.inria.fr/softrobot/install-get-started-2/download/ is actually equivalent!

    After adding in the PluginManager (as you described) the plugins (SoftRobots, STLIB) you will be able to run the scenes.

    Now, about your problem with Python scenes, it is due to the fact the v20.12 release is the first version of SOFA including the SofaPython3 plugin. All the scenes in SoftRobots were not yet updated to work with python3. Two solutions:
    – you use the SofaPython plugin instead (corresponding to SofaPython2.7) with SoftRobots
    – or (more modern and useful for a close future) I can help you to update one python scene of interest for you to work with SofaPython3!

    Looking forward to hearing from you,

    Hugo

    Hi Hugo, nice to hear from you in writing as well after watching you for some hours on youtube 😀

    Thanks for the notification that the screenshots are not viewable, I will paste the error code in the following.

    I tried to use the (Python2.7) SofaPython plugin with the following script of the SoftRobots tutorials 

    
from stlib.scene import MainHeader, ContactHeader
from stlib.visuals import ShowGrid
from stlib.physics.rigid import Floor
from stlib.physics.rigid import Cube

def createScene(rootNode):
    """This is my first scene"""
    MainHeader(rootNode, gravity=[0.0,-981.0,0.0])
    ContactHeader(rootNode, alarmDistance=15, contactDistance=10)

    Floor(rootNode,
          translation=[0.0,-160.0,0.0],
          isAStaticObject=True)

    Cube(rootNode,
          translation=[0.0,0.0,0.0],
          uniformScale=20.0)

    return rootNode

    however I get an STLIB(.scene) error. Do I need to manually download/add STLIB into some directory? I read in some other forum posts about out-of-tree and cmake in connection with STLIB but am not sure if I need to do that and if so how. I assumed it came with the latest SOFA version since it’s listed in the plugin manager.

    Nevertheless, the minimal python script example you presented in the youtube tutorial:

    
import Sofa

def createScene(node):
	node.gravity="0 0 0"
	node.name = "root"

	childNode = node.createChild("Particle")

	childNode.createObject('EulerImplicitSolver')
	childNode.createObject('CGLinearSolver',iterations="200",tolerance="1e-09")
	childNode.createObject('MechanicalObject', template="Rigid3d", name="myParticle",position="0 0 0 0 0 0 1", showObject="1")
	childNode.createObject('UniformMass',totalMass="1")
	childNode.createObject('ConstantForceField', name ="CFF", totalForce="1 0 0 0 0 0")

    works now (except a “scene radius must be positive – ignoring value” message)!

    I assume we have to get above to run before potentially moving to Python3?

    Thanks for your reply/help and best regards

    Hello everybody!

    I am actually gnawing at the exactly same problem as @Steph and would also appreciate if we could solve that issue 😉

    Thank you all very much in advance!

    Best regards!

    Hi @Steph & @Tori ,

    did you add the splib and stlib folder to your path?
    /PATH_TO_STLIB_FOLDER/python if your are using python 2.7
    and /PATH_TO_STLIB/python3/src if your are using python3.

    However, some scenes in the tutorial do not work with python3.
    It needs a few modifications, like swtich creatsChild with addChild and
    from stlib3.scene.Scene import Scene instead of from stlib.scene import MainHeader, ContactHeader

    For binairies add /PATH_TO_INSTALL/lib/python3/site-packages/ or /PATH_TO_INSTALL/lib/python2/site-packages/, and check that these folders are actually on your computer.

    Hi @younesssss, thanks for your reply.

    So I would like to use python 2.7 since to my understanding many of the softrobotic tutorials are still using python 2.7.

    I actually hadn’t manually added the stlib folder to my path yet.

    However, in my STLIB folder from the binaries I do have ...\SOFA_v20.12.02_Win64\plugins\STLIB\python but not the python3/src you mentioned, and on the opposite I have ...\SOFA_v20.12.02_Win64\plugins\STLIB\lib\python3\site-packages, and not the python2 site-packages –> so there seems to be a mismatch here (unless I am looking in the wrong folders).
    How would you proceed?

    Thanks for your help
    Steph

    Then add Path_to_\SOFA_v20.12.02_Win64\plugins\STLIB\python in your path since you want to use python2

    Hi @younesssss

    Thanks for your feedback, I implemented it.

    I can open and run SofaPython examples without errors, however STLIB is still causing trouble.
    I tried opening the CableConstraint.pyscn example in the \SOFA_v20.12.02_Win64\plugins\SoftRobots\docs\examples\component\constraint\CableConstraint folder and got the following error:

    Hi @Steph
    I think the easiest way to do this is to clone STLIB from Github and add it to your path.
    This way we are sure you have all the files.

    Sorry for my late answer.

    Hi @younesssss!

    As I am working on the exactly same issue as @Steph, I allow myself to answer;)

    I cloned the STLIB from GitHub and added it to my path- however it does not seem to solve that issue.

    I still get the following errors:
    [ERROR] [PythonScript] ImportError: No module named stlib.scene
    File “step0.pyscn”, line 2, in <module>
    from stlib.scene import MainHeader, ContactHeader

    [ERROR] [SofaPython] Script (file:step0) import error
    [ERROR] [SofaPython] scene script load error.

    Hi @steph @toriwalnuss

    I would like to inform you that we are currently working hard on improving the installation of SOFA/SoftRobots/STLIB and providing better step-by-step documentation. This should be ready for the next release (end of June : v21.06).

    Sorry for the inconvenience, we know your time is precious, especially during internships!

    Best wishes,

    Hugo

    The new release v21.06 is out for a month now (sorry for the delay, I was away these last weeks). The binaries include the latest version of SOFA, STLIB and the SoftRobots plugin!

    Your feedback would be most appreciated.
    Best wishes,

    Hi Hugo

    Unfortunately I can’t give you any updates from my side since I moved on to other challenges and haven’t tried out the newest version yet. If I do I will definitely let you know.

    Thanks for your support and best regards
    Steph
