How do I proceed? Because the python libraries are importing the equivalent C libraries, you also need to update LD_LIBRARY_PATH My (python 2) prefix looks like this: LD_LIBRARY_PATH=~/ceph/build/lib/ PYTHONPATH=~/ceph/build/lib/cython_modules/lib.2/ John > And how are the tests in test_volume_client.py executed using python2? > Doing "$python2 ../qa/tasks/vstart_runner.py --interactive --create > tasks.cephfs.test_volume_client" hasn't worked for me either. > > [1] https://github.com/rishabh-d-dave/ceph/blob/py2-to-py3/src/pybind/test.py > -- > To unsubscribe from this list: send the line "unsubscribe ceph-devel" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
