import yarp Error, or do i need to rebuild the yarp with pythonsupport ?

[jimingda]

Sorry to ask a repeated question here, as i asked somewhere else robotology/yarp#2975 , the question is

I set the PYTHONPATH, but still failed to import yarp.

(base) icub@icubsrv:/usr/local/src/robot/robotology-superbuild/build/src/YARP/bindings$ echo $PYTHONPATH
/usr/local/src/robot/robotology-superbuild/build/src/YARP:/usr/local/src/robot/robotology-superbuild/build/src/YARP/bindings
(base) icub@icubsrv:/usr/local/src/robot/robotology-superbuild/build/src/YARP/bindings$ python
Python 3.8.16 (default, Mar 2 2023, 03:21:46)

Type "help", "copyright", "credits" or "license" for more information.
>>> import yarp
Traceback (most recent call last):
File "", line 1, in
ModuleNotFoundError: No module named 'yarp

Or if i need to rebuild or super-build the yarp with pythonsupport, how to do it?

Regards.

Yes, you ought to rebuild the superbuild with Python enabled. To this end, there's the following CMake flag to toggle on:

• ROBOTOLOGY_USES_PYTHON
