I compile and install misc3d 0.4.0 version
and open3d version is 0.16.1
$ python

Hi @dbdxnuliba , how did you install open3d? did you build it from source and install the python pybind by running make install-pip-package?

[dbdxnuliba]

yes , but I use open3d version is 0.16.1 ,is the version is too old

[yuecideng]

open3d with version >= 16 is acceptable. I think the problem might be 1. the inconsistent of the compilation configuration (eg. different version of compiler gcc/g++). 2. The linking problem of libOpen3D.so (check libMisc3D.so can find the correct libOpen3D.so by using ldd -r xxx/libOpen3D.so
