Can't launch Python script directly with python3

[Hoangn06]

Hello,

I've a problem about launching python script directly with command ( python3 script.py). In this example, I've tried to run the script from Training: python3 17-python3-new-forcefield.py.

Before launching the script, I've done like the instruction in https://sofapython3.readthedocs.io/en/latest/content/Installation.html with:

export SOFA_ROOT=/Users/hoangnguyen/Documents/SOFA_Framework/SOFA_v24.12.00_MacOS
export PYTHONPATH=/Users/hoangnguyen/Documents/SOFA_Framework/SOFA_v24.12.00_MacOS/plugins/SofaPython3/lib/python3/site-packages
export PATH="/Library/Frameworks/Python.framework/Versions/3.12/bin"

But I've received an error message:

Can someone know this error and can help me please? Thank you and have a great day!

[bakpaul]

Hello !

This is related to your OS not being able to find Python3.12 when opening the shared library libSofaPython3.dylib. In MacOS this is done using a @rpath. You could either enrich the rpath of the library by running
install_name_tool -change @rpath/Python.framework/Versions/3.12/Python /absolute/path/on/your/machine/to/Python.framework/Versions/3.12/Python /Users/hoangnguyen/Documents/SOFA_Framework/SOFA_v24.12.00_MacOS/plugins/SofaPython3/lib/python3/site-packages/Sofa/Helper.cpython-312-darwin.so

Or you could give hint to your OS by appending the path needed to replace @rpath in @rpath/Python.framework/Versions/3.12/Python in order to find the lib. This is done like this :
export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:/path/that/you/want/to/add:/another/path/
You can either call this line in the terminal you are launching SOFA before launching it or you can set it for every bash sessions by adding this line to your ~/.bash_profile if you are using bahs or ~/.zshrc if you are using zsh.

I prefere second option, becaus eusing the first one you'll need to do it for each lib in the SOFA binaries that depends on Python3.12

[hugtalbot]

Hey @Hoangn06

• Have you tried to run the command given by Paul?
  install_name_tool -change @rpath/Python.framework/Versions/3.12/Python /absolute/path/on/your/machine/to/Python.framework/Versions/3.12/Python /Users/hoangnguyen/Documents/SOFA_Framework/SOFA_v24.12.00_MacOS/plugins/SofaPython3/lib/python3/site-packages/Sofa/Helper.cpython-312-darwin.so
• Can you try to add Library/Frameworks/Python.framework/Versions/3.12/bin in the PYTHONPATH?
• Can you make sure that /Library/Frameworks/Python.framework/Versions/3.12/bin is not empty?

[bakpaul]

First thing first : make sure you have Python3.12 installed.
Then, findout where it is actually installed. Find the absolute path where you can find this : Python.framework/Versions/3.12/Python.
Let's say you have this on your install : /Frameworks/opt/Python.framework/Versions/3.12/. Then what you need to do is either :

1. call export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:/Frameworks/opt/ in the terminal before launching sofa, but in the same terminal.
2. Add this line export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:/Frameworks/opt/ in either /.bash_profileor/.zshrc` depending on the type of terminal you are using

[Hoangn06]

Hello @hugtalbot @bakpaul

I've tried and checked like you all said but none of the method work.

My Pythonis installed in 4 different paths all are 3.12

I've check Library/Frameworks/Python.framework/Versions/3.12/bin is not empty.

I've tried so many ways like you said.

1. First I tried this combination:

install_name_tool -change @rpath/Python.framework/Versions/3.12/Python /absolute/path/on/your/machine/to/Python.framework/Versions/3.12/Python /Users/hoangnguyen/Documents/SOFA_Framework/SOFA_v24.12.00_MacOS/plugins/SofaPython3/lib/python3/site-packages/Sofa/Helper.cpython-312-darwin.so

export SOFA_ROOT=/Users/hoangnguyen/Documents/SOFA_Framework/SOFA_v24.12.00_MacOS
export PYTHONPATH=/Users/hoangnguyen/Documents/SOFA_Framework/SOFA_v24.12.00_MacOS/plugins/SofaPython3/lib/python3/site-packages
export PATH="/Library/Frameworks/Python.framework/Versions/3.12/bin"

The output is

2 - Second try like @hugtalbot said
I run this combination:

install_name_tool -change @rpath/Python.framework/Versions/3.12/Python /absolute/path/on/your/machine/to/Python.framework/Versions/3.12/Python /Users/hoangnguyen/Documents/SOFA_Framework/SOFA_v24.12.00_MacOS/plugins/SofaPython3/lib/python3/site-packages/Sofa/Helper.cpython-312-darwin.so

export PYTHONPATH=/Library/Frameworks/Python.framework/Versions/3.12/bin
export PATH="/Library/Frameworks/Python.framework/Versions/3.12/bin"

Output is

3 - Like @bakpaul said. I've launched this combination

export SOFA_ROOT=/Users/hoangnguyen/Documents/SOFA_Framework/SOFA_v24.12.00_MacOS
export PYTHONPATH=/Users/hoangnguyen/Documents/SOFA_Framework/SOFA_v24.12.00_MacOS/plugins/SofaPython3/lib/python3/site-packages

Am I missing something or doing something wrong here?...

Thank you @bakpaul @hugtalbot

[bakpaul]

You are doing two things wrong. Actually, you did the first wrong thing at the very begining, leading to your second mistake making all of your other attempts fail.

• First mistake : Using the install_name_tool at your first attempt removed the @rpath from the lib. Meaning that the OS in not looking into the DYLD_LIBRARY_PATH variable anymore. This wouldn't be an issue if you gave the right path, but you provided /absolute/path/on/your/machine/to/Python.framework/Versions/3.12/Python. This was an example, you should have put the real absolute path. Given you image, it seems that it should have been /Library/Frameworks/Python.framework/Versions/3.12/Python. You could try to fix this by calling
  install_name_tool -change /absolute/path/on/your/machine/to/Python.framework/Versions/3.12/Python /Library/Frameworks/Python.framework/Versions/3.12/Python /Users/hoangnguyen/Documents/SOFA_Framework/SOFA_v24.12.00_MacOS/plugins/SofaPython3/lib/python3/site-packages/Sofa/Helper.cpython-312-darwin.so .
• Second mistake : As said, removing the @rpath changed the behavior of the loading of the lib. NOw it doesn't look into DYLD_LIBRARY_PATH to find it. So all of your attempts following the call to install_name_tool are failing by design and you shouldn't conclude anything from them. You mistake here is that you haven't put the original path to the lib. Or at least you should have backed-up the lib before modifying it so you could have switched it after your failed attempt with install_name_tool

[Hoangn06]

Sorry for the error in absolute path.

I've tried to fix it with:

install_name_tool -change  /absolute/path/on/your/machine/to/Python.framework/Versions/3.12/Python /Library/Frameworks/Python.framework/Versions/3.12/Python /Users/hoangnguyen/Documents/SOFA_Framework/SOFA_v24.12.00_MacOS/plugins/SofaPython3/lib/python3/site-packages/Sofa/Helper.cpython-312-darwin.so . 

And then I launch:

export SOFA_ROOT=/Users/hoangnguyen/Documents/SOFA_Framework/SOFA_v24.12.00_MacOS
export PYTHONPATH=/Users/hoangnguyen/Documents/SOFA_Framework/SOFA_v24.12.00_MacOS/plugins/SofaPython3/lib/python3/site-packages
export PATH="/Library/Frameworks/Python.framework/Versions/3.12/bin"

It seem right now I could not find my python3.12....

[bakpaul]

No it is the same error, you need to apply this install_name_tool to each lib depending on Python. libSofaPython3 is one of them. That is why I've suggested the solution with DYLD_LIBRARY_PATH. It could work for every lib. Maybe try again to export this to see if it solves anything.

[Hoangn06]

I've tried to export DYLD_LIBRARY_PATH again:

export SOFA_ROOT=/Users/hoangnguyen/Documents/SOFA_Framework/SOFA_v24.12.00_MacOS
export PYTHONPATH=/Users/hoangnguyen/Documents/SOFA_Framework/SOFA_v24.12.00_MacOS/plugins/SofaPython3/lib/python3/site-packages
export PATH="/Library/Frameworks/Python.framework/Versions/3.12/bin"
export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:/Library/Frameworks

Still the same error arise:

[Hoangn06]

Hello @bakpaul and @hugtalbot,

I'm still blocked with this problem. Do you have any suggestions to solve it...?

Thank you and have a great day

[bakpaul]

Ok the only solution I see is to make the same call to install_name_tool -change @rpath/Python.framework/Versions/3.12/Python /Library/Frameworks/Python.framework/Versions/3.12/Python /Users/hoangnguyen/Documents/SOFA_Framework/SOFA_v24.12.00_MacOS/plugins/SofaPython3/lib/python3/site-packages/Sofa/Helper.cpython-312-darwin.so for this lib and all the one that will fail in the future.

I am sorry, but I am not a specialist of MacOS. This kind of issue are way easier to solve on Linux/Windows. If it still doesn't work, I'll ask help from other core dev.
