Error occurs when I install pygicp using Python3... (ImportError) about fast_gicp HOT 5 OPEN

I had this issue too, seems like pcl introduces a dependency on /usr/bin/python2.7 as mentioned here and here. To check if this is what is causing your issues, take a look at the build/temp./Cmakefiles/pygicp.dir/flags.make, you should find -I /usr/bin/python2.7 . As a temporary workaround, two approaches worked for me

1. renaming /usr/bin/python2.7 to something else, installing the package with setup.py as mentioned above and then renaming the folder back to python2.7. This is hacky, but the easiest workaround for the issue.
2. A slightly better but still hacky way is to use regexes to filter out python2.7 in the cmakelists file from PCL_INCLUDE_DIRS and the INCLUDE_DIRS for pygicp and fast_gicp.

Approache 1 worked, but it should be renaming /usr/include/python2.7 to somewhere else, rahter than /usr/bin/python2.7

It seems the package was installed to your python2 environment. Try the following installation command (don't forget "3" after python)

python3 setup.py install --user

This is not working for me.

import pygicp
Traceback (most recent call last):
File "", line 1, in
ImportError: dynamic module does not define module export function (PyInit_pygicp)

I can confirm this was also the case for me.
However, it seems to depend only on what is used in build/temp./Cmakefiles/pygicp.dir/flags.make, so i'd suggest to verify which path is used there and rename that one.
