intallation problem with python-pcl

[gfjiyue]

Anaconda3, pcl 1.8.1, vs2015 I did as instruction at https://github.com/strawlab/python-pcl, but meet a problem: (D:\Anaconda3) C:\Users\fieldphenomics>python D:\programfiles\python-pcl-master\setup.py build_ext -i set environment PKG_CONFIG_PATH=D:\programfiles\python-pcl-master\pkg-config\pkg-config.exe C:\Users\fieldphenomics\pkg-config\pkg-config.exe Traceback (most recent call last): File "D:\programfiles\python-pcl-master\setup.py", line 153, in if subprocess.call(['.\pkg-config\pkg-config.exe', 'pcl_common%s' % pcl_version]) == 0: File "D:\Anaconda3\lib\subprocess.py", line 267, in call with Popen(*popenargs, **kwargs) as p: File "D:\Anaconda3\lib\subprocess.py", line 709, in init restore_signals, start_new_session) File "D:\Anaconda3\lib\subprocess.py", line 997, in _execute_child startupinfo) FileNotFoundError: [WinError 2] The system cannot find the file specified

see 60# Download Gtk + for Windows before calling setup.py and copy the extracted binary to the pkg-config folder.

[gfjiyue]

Yes, I did as the instrucation said. I executed powershell file [Install-GTKPlus.ps1]. But still have this problem. @diyoejw

[Sirokujira]

@gfjiyue Please change the directory to "D:\programfiles\python-pcl-master" and build it.

• cd /d"D:\programfiles\python-pcl- master"

[gfjiyue]

Yes, it works! @Sirokujira. But there is another problem, can you help me? (base) D:\programfiles\python-pcl-master>python setup.py build_ext -i set environment PKG_CONFIG_PATH=C:\Users\fieldphenomics\Desktop\python-pcl-master\python-pcl-master\pkg-config\pkg-config.exe D:\programfiles\python-pcl-master\pkg-config\pkg-config.exe setup.py: error: cannot find PCL, tried pkg-config pcl_common-1.8 pkg-config pcl_common-1.7 pkg-config pcl_common-1.6 pkg-config pcl_common

I reinstalled the PCL to another file "D:\programfiles\PCL1.8.1" and solved the problem mentioned above. However, new problem comes： cl.exe /c /nologo /Ox /W3 /GL /DNDEBUG /MD -DEIGEN_YES_I_KNOW_SPARSE_MODULE_IS_NOT_STABLE_YET=1 -D_CRT_SECURE_NO_WARNINGS=1 -IC:\Users\fieldphenomics\Anaconda3\lib\site-packages\numpy\core\include -ID:\programfiles\PCL1.8.1\include\pcl-1.8 -ID:\programfiles\PCL1.8.1\3rdParty\Eigen\eigen3 -ID:\programfiles\PCL1.8.1\3rdParty\Boost\include\boost-1_64 -ID:\programfiles\PCL1.8.1\3rdParty\FLANN\include -ID:\programfiles\PCL1.8.1\3rdParty\VTK\include\vtk-8.0 -IC:\Users\fieldphenomics\Anaconda3\include -IC:\Users\fieldphenomics\Anaconda3\include /EHsc /Tppcl_pcl_180.cpp /Fobuild\temp.win-amd64-3.6\Release\pcl_pcl_180.obj /EHsc error: command 'cl.exe' failed: No such file or directory

[gfjiyue]

Maybe the reason is it includes space in the path. However, there is no option to change the path during the installation of Microsoft Visual C++ Build Tools on windows. It only can be intalled in C:\Program Files (x86).

Hi, I used the same setting as you did at the beginning but failed to solve the problem. Did you solve this problem? @gfjiyue Could you show me some guidance on how to install Gtk+ in windows and extract the binary to pkg-config folder? (It is the folder in python-pcl ?) Thanks.

Hi I get this error when trying to install I have installed all the requirements uninstalled and reinstalled cython also.

@gfjiyue, try to install newer version of anaconda from here, Then try to use this command conda install -c sirokujira python-pcl It will work I guess :)

[xiuliren]

@niranjanreddy891 the installation is a success, but got an error while using it.

In [1]: import pcl

It looks like a python version incompatibility. I am using it in python 3.6.

[niranjanreddy891]

@jingpengw, can you please share the following

1. Operating system version
2. Commands used to create & build the workspace
3. Version of boost installed

[xiuliren]

sure, ubuntu 14.04 I manually built the pcl 1.8.1 from source. libboost 1.55

[niranjanreddy891]

@jingpengw, Try upgrading boost to the latest version here I guess this will solve the problem. Also try to reinstall the python-pcl. :)

[xiuliren]

@niranjanreddy891 thanks, I tried to upgrade to latest boost 1.67, but got worse. The pcl 1.8.1 was not compiled successfully.

[niranjanreddy891]

@jingpengw, You are using older version of ubuntu. PCL-1.8.1 supports Ubuntu > 16.04. Try to upgrade your O.S. Also make sure that jdk is installed properly. If you want to install jdk, try this command sudo add-apt-repository -y ppa:webupd8team/java && sudo apt update && sudo apt -y install oracle-java8-installer Sorry for informing late about o.s problem. :)

[xiuliren]

@niranjanreddy891 Thanks, it is a hard decision to upgrade since I have a lot of work configuration and installation there.

[niranjanreddy891]

@jingpengw, try to use pcl-1.7.1. :)

[shenqildr]

@niranjanreddy891 Thanks, it is a hard decision to upgrade since I have a lot of work configuration and installation there. Have you solved the problem?

[niranjanreddy891]

Yes. Could you please tell me on which environment you are working on including version?

[shenqildr]

ubuntu 16.04 python3.5 pcl-1.8.1 I have installed libboost already,but it shows
from ._pcl import * ImportError: libboost_system.so.1.66.0: cannot open shared object file: No such file or directory what's more, i have tried all the commends : conda config --add channels conda-forge conda install -c sirokujira python-pcl
