I followed the instructions, have pcl and other dependencies install. Yet I get the error when I run the setup file:

:~/python-pcl-master$ python setup.py build_ext -i

I have attached the complete error file. Error.docx

Any pointers will be useful. Thanks

Had the same issue, which was probably related to package versions, installation in a virtual environment worked for me:

in python-pcl folder:

virtualenv -v virtual_build_env source virtual_build_env/bin/activate pip install --upgrade pip pip install cython==0.25.2 pip install numpy python setup.py build_ext -i python setup.py install --user

test installation: python examples/official/Filtering/PassThroughFilter.py

We have confirmed that the same phenomenon occurs when Cython 0.28 is installed. As for correspondence, we will correspond with the next version.

For now, please specify version 0.25.2 of Cython.

FYI Cython 0.25.2 can't be installed on Python 3.7 and newer
