Python binding failed

[manhha1402]

Hi @yuecideng ,
I followed the instruction to install and run examples in the repo and got the error with python binding, for example: farthest_point_sampling.py: TypeError: farthest_point_sampling(): incompatible function arguments. The following argument types are supported.
I use ubuntu 20.04, open3d installed with CUDA enable.
Do you know how to solve the issue?.
Thank you

Hi, how did you build open3d? Did you install open3d python package after build open3d from source?

[manhha1402]

Hi, yes. I built Open3d from source and open3d pybind package after building open3d from souce.

I'm not sure whether the mismatch of open3d data type is caused by the CUDA anbled. Previously I developed misc3d with cpu only version of open3d and did not try to use CUDA enbled open3d with misc3d. I will try it if I have bandwidth for it.

which function you would like to use in misc3d? If you want to use farthest_point_sampling, it has been integrated into open3d since 0.16.0. @manhha1402

Hi @yuecideng ,
Actually I want to do the python binding for some C++ functions using Open3d like you but it was't successful. I did the same as you here: https://github.com/yuecideng/Misc3D/tree/main/python and got the same error : incompatible function arguments. The following argument types are supported.
Do you know how to fix it?. Thank you

You may try to check both the misc3d pybind so and open3d pybind so link to the same libOpen3D.so.

Thank you for your suggestion. Do you have a plan develop CUDA implementation for ppf pose estimation or integrate to Open3D?

[yuecideng]

Yeah I am doing this and glad to contribute it to Open3D. But it may take some time due to my limited bandwidth.
