ImportError

[JuanDuGit]

Hi, thanks for sharing the code. I have compiled and installed this module successfully, but encountered the following ImportError when trying import it in python script.

>>> import PCLKeypoint Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: dynamic module does not define module export function (PyInit_PCLKeypoint)
I am using Ubuntu 18.04.3 LTS and the python version is 3.6.9.

Do you possiblly have any ideas how to fix this problem?

I have no clue why this happens. Maybe you can post your compilation results here? One more thing, importing the module at its directory may cause error. For example, running python; import pclkeypoint in the directory of pclkeypoint or the parent directory of pclkeypoint may cause errors.

I have also run into this problem. Did you fix this issue? if yes could you please help me?

@ngthanhtin I suspect the issue happens at the link time. I temporily fixed this by using py2 isntead of py3. Probably not the most right thing to do, but worked for me

It seems that the installed PCL has been linked to the python2, which may include /usr/include/python2.7 (you can find this in PCLKeypoint_LIB_DEPENDS from CMakeCache.txt ).
So I recompile the PCL 1.11.0, and the problem has gone.

this worked for me I installed pcl with sudo apt install libpcl-dev instead I compile PCL 1.11.0 on ubuntu 18.04 and problem solve
