Hi, Thanks for the great work! I use TF1.12 ,cuda9.0 and cudnn7.4.2. And I also got libtf_grouping.so libtf_interpolate.so libtf_sampling.so. But I met the error when I run test_tf_ops.py.

Traceback(most recent call last): File "test_tf_ops.py", line 4, in <module> from tf_grouping import query_ball_point, group_point, knn_point File "/media/orange/work/Open3D-PointNet2-Semantic3D-master/tf_ops/tf_grouping.py", line 9, in <module> os.path.join(BASE_DIR, "build", "libtf_grouping.so") File "/home/orange/anaconda3/lib/python3.6/site-packages/tensorflow/python/framework/load_library.py", line 60, in load_op_library lib_handle = py_tf.TF_LoadLibrary(library_filename) tensorflow.python.framework.errors_impl.NotFoundError: /media/orange/work/Open3D-PointNet2-Semantic3D-master/tf_ops/build/libtf_grouping.so: undefined symbol: _ZN10tensorflow8internal21CheckOpMessageBuilder9NewStringEv

solved by using TF 1.8 from pip install. Thanks for the other issues!
