Expected behavior

rclpy successfully imported.

Actual behavior

Import failure.

Additional information

I'm not sure what's causing this issue. A ROS 2 scripts on my machine that worked before suddenly stopped working, and it turned out to be a import failure. Also, the trobleshooting guide in the error message seems to be only for Windows. Thank you.

What is the output of python3 -VV ?

[squizz617]

[mjcarroll]

Ah, I didn't read closely enough, this is likely the culprit:

ImportError: librcl_action.so: cannot open shared object file: No such file or directory

Do you have ros-humble-rcl-action installed? You should also have the library located at /opt/ros/humble/librcl_action.so from the binaries.

[clalancette]

Further, what does your environment look like?

$ printenv | grep -i ros

[squizz617]

I have ros-humble-rcl-action installed.

$ apt list | grep humble-rcl-action

[squizz617]

The issue persists after upgrading ros-humble apt package to ros-humble-rcl-action/jammy,now 5.3.4-3jammy.20230721.204515 amd64 [installed,automatic]..

[mjcarroll]

I'm pretty stumped here. I suppose as a next step, you could look at each of the dependent shared libraries and make sure that they can correctly resolve their dependencies via ldd?

[iuhilnehc-ynos]

@squizz617

I'm interested in this issue because it's almost impossible as the ldd shows that the rcl_action.so is found.

Could you run the command strace python3 -c "import rclpy" > /tmp/failed-to-import-rclpy.txt 2>&1, and then upload the log /tmp/failed-to-import-rclpy.txt?

[squizz617]

@iuhilnehc-ynos Here's the strace of python3 importing rclpy: strace_rclpy.txt.

[iuhilnehc-ynos]

According to access("/etc/suid-debug", F_OK), I believe that you changed the /usr/bin/python3.10 with '+s' which will erase the LD_LIBRARY_PATH.

Please revert it with sudo chmod -s /usr/bin/python3.10.

[squizz617]

I believe that you changed the /usr/bin/python3.10 with '+s'

@iuhilnehc-ynos Thanks for the suggestion but I haven't set the setuid bit..

$ ls -alh /usr/bin/python3.10 
-rwxr-xr-x 1 root root 5.7M Jun 11 01:26 /usr/bin/python3.10

[iuhilnehc-ynos]

Wow, so there are other cases can make the __libc_enable_secure get true and then call unsetenv the LD_LIBRARY_PATH.

Besides the manually setting suid for the /usr/bin/python3.10, another case I can think of is the mount option.

@squizz617 Could you show the mount options for the device?

[DRAGON-BOOSTERR]

I also have the same problem, for me the command import rclpy was not working in pycharm and after some messing around I found that we need to add the interpreter paths in pycharm. after that I ended up this error and by following this beautiful thread, Im looking for a way forward. but when I run the code with just the python command python3 ros_test.py, the program runs.

PS: I was following a udemy tutorial on ROS2

[chenyenru]

@DRAGON-BOOSTERR May you elaborate on how you solved the problem? I'm having the same problem too 😭

[DRAGON-BOOSTERR]

@chenyenru yeah here is the stackover flow page that I raised the issue and answered myself https://stackoverflow.com/questions/76983995/python-package-is-installed-but-it-doesnt-get-detected-in-a-ide-ros2/77009205#77009205

[chenyenru]

Thank you! I was able to solve it by deactivating my anaconda environment (don't know why but that way my Python interpreter finds rclpy package).

[DRAGON-BOOSTERR]

@chenyenru @squizz617 Hey guys I think i found a short term fix for this issue! As said before I was having problems with IDEs not recognising the rclpy library of ROS2. As by the comment yesterday I mentioned how I solved the problem by adding the interpreter paths in Pycharm IDE. The Pycharm IDE tries to run the file inside the IDE or something like that and received the same error as the title of this thread. Today I tried the code with visual studio code, surprisingly VS code recognised that rclpy library and showed all the auto complete and other things of that library. Since VS code runs every file in terminal inside the IDE, so the code works without any issues. I think this might fix your problem with that error?

[chenyenru]

I was able to include extra paths in the settings.json file, where the interpreter would successfully autosuggest functions from the rclpy library.

However, when I tried to compile it on the IDE, it still showed that rclpy was not found. I was able to resolve this problem by not running it on conda environment and instead the base file while installing required packages with pip. Hope this result would help you too!

[fferri]

I got the exact issue reported by OP. Turned out I was overriding LD_LIBRARY_PATH for the process responsible for spawning python3. Appending/prepending paths to LD_LIBRARY_PATH -instead of overriding- fixed the issue for me.

[asukiaaa]

I could resolve this problem by removing all packages of using ros2 distribution and install again.

sudo apt remove ros-rolling-*
sudo apt install ros-rolling-desktop-full

[2019lelexia]

According to this, https://docs.ros.org/en/rolling/How-To-Guides/Installation-Troubleshooting.html#import-failing-without-library-present-on-the-system I think we cannot use different version of Python because the Python of ROS2 build different binary file of C extension from the Python of another

[yerkgb]

I had a same problem. These two lines are helped me out: $sudo apt install --reinstall ros-humble-rclpy $source /opt/ros/humble/setup.bash Try your luck!

Also, on your .bashrc file try to source ros directory at the end after all lines.

[sungchan1]

I finally managed to solve the problem and wrote a blog post about it in Korean.

https://du-sungchan-24k.tistory.com/37

In summary, you need to directly inject this into your pycharm.sh script.

. /opt/ros/humble/setup.sh' If installed via Jetbrain Toolbox, your pycharm.sh will be located at

'/home/{USER_NAME}/.local/share/JetBrains/Toolbox/apps/{pycharm_version}/bin/pycharm.sh'. For Jetbrain Remote Development, pycharm.sh is in

'/home/{USER_NAME}/.cache/JetBrains/RemoteDev/dist/{cached_pycharm_version}/bin/pycharm.sh'. The same applies to CLion and IntelliJ.

You should check if the Python environment for ROS matches the current terminal's Python environment. I noticed your terminal is using Python 3.11, but ROS is looking for Python 3.12, which could be why it can't find the required library. This is just my guess.
