| Dec 29, 2023 at 17:53 | comment | added | aarsht7 | I tried the solution mentioned above by Lucas and it worked for me. TO BE MENTIONED HERE, I tried everything on the docker and it has only one version of python3 installed that delivered with installation of the ros from the official ros-docker image. So at the end it seem to be a problem of the roslaunch and the python version it might be using on backend and not the python3. I felt it was bit rude the closing of the question without listining or understanding the issue but anyway. | |

When you see RLException: Unable to launch If it is a script,.. It is because you forgot to give excecution permission ig. I faced the same error but after chmod +x filename.* it gave the Bad magic error

I tried docker and see the same RLException: Unable to launch If it is a script,.. (I think any time you saw Bad magic that's from running a pyc from a different python version, probably the outside one)- but the wrapper worked. So the issue is something different with any combination of ros or python versions or the docker environment vs. outside docker.

| Dec 19, 2023 at 8:48 | comment | added | aarsht7 | Thing is pyc files worked on the local machine as well. it's just docker that is struggling with pyc. I will try your suggestion in docker for confirmation. But for now, I have decided to try pyinstaller to generate distributable bundle file. Just that it take up more storage than the pyc file as it packs all the dependancy togather so I am not sure if I will continue using pyinstaller | |

I'll convert this to an answer if this gets reopened, this worked (outside of docker at least, haven't tested inside it) using python 3.11: python -m compileall `rospack find talker`, <node pkg="talker" type="talker.sh" name="talker_pyc" output="screen"/> then in scripts/talker.sh wrapper script: #!/bin/bash python `rospack find talker`/scripts/__pycache__/talker.cpython-311.pyc
