openalea
After conda installation, can't run lpy
I'm on linux.
I have created conda enviroment with conda create -n lpy openalea.lpy -c openalea and activated it.
Running lpy gives:

ImportError: libboost_python.so.1.66.0: cannot open shared object file: No such file or directory
conda list prints that it installed libboost 1.65.1 habcd387_4 so I guess it just installed wrong version of libboost.
I will try install libboost 1.66.0 manually and will tell you if it solves the problem.
It seems you are on Linux, isn't it?
Remove your environment (conda remove -n lpy --all) and recreate it using the folloing command:
conda create -n lpy openalea.lpy openalea.plantgl 'boost =1.66.0' -c openalea

I have just run conda install boost=1.66.0 and it works now. (updated to 1.66)
Anyway docs should be updated :)
Yes, I'm on Linux.
Cool. There is a strange bug. The boost code is take from anaconda rather than openalea channel. Conda do not respect priority. We have to investigate why.
Where do you take the instructions?

I took instructions from http://lpy.readthedocs.io/en/latest/user/installing.html#installing-using-conda-linux-mac-windows.
This is quick fix: conda create -n lpy openalea.lpy boost=1.66.0 -c openalea but it still not what we want, because other packages are still taken from openalea only when they are not found in other channels.
I have also tried conda config --add channels openalea && conda create -n lpy openalea.lpy --channel-priority which sets openalea as the default channel, but still boost is not taken from openalea.
Yea, so it's definitely a conda bug. I will submit an issue on conda github unless I'm the only one with such strange behavior. Am I?
edit: conda -V gives conda 4.5.0
Hey, I just wanted to chime in that I am having this issue as well. However, when I specifically install boost=1.66.0 I get the error ImportError: libboost_thread.so.1.65.1: cannot open shared object file: No such file or directory. So it seems like LPy is trying to use 1.66 and 1.65 simultaneously.
The fix is to remove boost and py-boost and openalea.lpy. Then, you can reinstall them using the following command:
conda install -c openalea openalea.lpy boost=1.66 -y
That worked for me on one of my linux dev machines and my osx laptop, but not a second linux machine. It looks like there is a conflict somewhere on my end so sorry for cluttering the comments.
On a somewhat related note which might be better placed elsewhere, I had tried building from source, but it looks like the SConscript file for the lpy wrapper dosn't include the qt path and so module.h couldn't find the QtCore/QtSharedData header. I was able to get scons to run by adding lib_env.EnableQtModules( [ 'QtCore']) to the wrapper SConscript file, but running python setup.py install caused a segfault.
I am not very familiar with scons, so perhaps I am missing something.
No problem. Thank you for reporting your problems; It help us a lot.
First, you have a problem with a linux machine. What is your distribution? Do you have boost installed in the system (/usr/lib/...)? Can you send me the result of the command:
conda info --all
For building from source, the easiest way is to use (at the root dir):
conda build -c openalea conda/.
You may need to install conda-build in your root (or base) environment before:
conda install -n root conda-build
We can discuss later on how to build the source directly. Thanks again
I am on ubuntu 14.04, but I dont think it is the linux flavor. I was eventually able to install LPy from conda on that machine after doing a full update of all conda packages and removing versions of some of the major packages lpy requires (qhull, cgal, boost, all openalea packages) that I had installed previously. Unfortunately I don't have a list of the packages from before to pinpoint which package was causing the issue. This even worked with two versions of boost installed (one installed via apt at the system level for another project). I have a suspicion that it might be the cgal package as I had also been using the eigen3 package from a non-standard channel that is probably out of date.
On linux, after the installation of lpy following the previous advice concerning libboost 1.66, I have this error concerning the "sip module"
How can I fix it ?

Perhaps it uses a sip on your system and not in conda.
Just do:
conda install sip

Hello,
On linux (ubuntu 16.04 LTS) I had the same problem when importing openalea.plantgl: "libboost_python.so.1.66.0: cannot open shared object file: No such file or directory"
Worked for me when installing boost as:
conda install boost=1.66.0 -c conda-forge
Regards !
Rami
