ROS2: DebugModuleNotFoundError: No module named 'rclpy._rclpy'

I am building ROS2 Debug Source Build on Windows (Using python_d). C++ examples works fine. But when try to run the python example get the following error:

I’m following the steps mentioned: https://github.com/ros2/ros2/wiki/Windows-Development-Setup

Any suggestion, how to resolve these?

Regards
Mrutunjayya,

thanks @mrutyu1987 for reporting.

By the look of it it looks like the python debug libraries have not been found when you built.

Can you confirm that you have a file called _rclpy_d.pyd in D:\Test\ROS_Source_Build\Debug_Python\install\Lib\site-packages\rclpy ?

I would expect the result to be the same but can you try to run the executable directly:

call D:\Test\ROS_Source_Build\Debug_Python\install\setup.bat
D:\Test\ROS_Source_Build\Debug_Python\install\Lib\demo_nodes_py\talker.exe

Finally can you provide your build output of rclpy and demo_nodes_py ?

rmdir /S D:\Test\ROS_Source_Build\Debug_Python\build\demo_nodes_py D:\Test\ROS_Source_Build\Debug_Python\build\rclpy
python_d D:\Test\ROS_Source_Build\Debug_Python\src\ament\ament_tools\scripts\ament.py build --cmake-args -DCMAKE-BUILD_TYPE=Debug -- --only rclpy demo_nodes_py

Thanks!

Thanks @marguedas.

I do not see _rclply_d.pyd file in the site-packages\rclpy folder.

Re-Built as mentioned in your response still not “_rclply_d.pyd”. Here is the build log as you mentioned:

@mrutyu1987 sorry looks like ther was a typo in my message. can you try the same thing with
-DCMAKE_BUILD_TYPE=Debug ?
You should see

Found PythonExtra: _d.pyd

@marguedas

In the build command i’m using

–cmake-args -DCMAKE-BUILD_TYPE=Debug

isn’t it correct?

Regards,
MJay

the name of the cmake variable is CMAKE_BUILD_TYPE (with only underscores) (https://cmake.org/cmake/help/v3.5/variable/CMAKE_BUILD_TYPE.html). Right now it is trying to build in “None” that’s why the libraries dont have the right suffix

@marguedas

thanks now i can see the file. But I get the following runtime python_debugError error attached
screenshot. Should this go on different thread?

Regards,
Mjay

hmm that looks a lot like an issue I faced recently https://github.com/ros2/rclpy/pull/101/files
Can you try to apply the same change and see if you still have the same error ?

Yes…still the same error.

Regards,
MJay

Yeah let’s move it to a different thread then.
Can you open an issue on rclpy with:

  • your configuration:

    • Windows version
    • Visual Studio version
    • Python version
    • which rmw_implementation you use
  • the exact list of commands you ran

  • a stacktrace (or the callstack from Visual Studio debugger)

  • if it works in Release mode but not in Debug mode

  • if it works when you build master instead of beta2

  • Any other information you think will be useful for us to reproduce your issue.

Thanks!

@marguedas Thanks for your assistance. I will create a new thread for the issue under rclpy
.
