I am simulating osx-64 on an M1 mac and am using openalea.lpy version 3.9.2. Running lpy gives the following errors:
qt.qpa.window: <QNSWindow: 0x7fab8a882260; contentView=<QNSView: 0x7fab8a881e60; QCocoaWindow(0x600002504d10, window=QWidgetWindow(0x60000365db60, name="QWidgetClassWindow"))>> has active key-value observers (KVO)! These will stop working now that the window is recreated, and will result in exceptions when the observers are removed. Break in QCocoaWindow::recreateWindowIfNeeded to debug.

zsh: bus error lpy
For some reason, I am unable to download later versions of openalea.lpy using conda, so I am unable to see if later versions have the same behavior.
Dear sir,when I use lpy, it reports that the lpy kernel package is missing. Does the current version not include this package? Looking forward to your answers and help, thank you very much!
Add a local conda package for LPy.
Activate Continous Integration
The OpenAlea namespace is not declared when bulding with conda.
Hi,
I am trying to install Lpy on a Windows 10 machine from Conda.
I have installed Conda but I can't install Lpy
The command conda create -n lpy openalea.lpy openalea.plantgl 'boost =1.66.0' -c openalea raises the following error:
Solving environment: failed
PackagesNotFoundError: The following packages are not available from current channels:
- openalea.lpy
- openalea.plantgl
On Windows, the conda installation works !!!
However, the IPython shell is missing while both qtconsole, jupyter and ipykernel have been installed.
Hi,
I am looking for a way to export a scene to ply format from within python.
Is this possible?
Thanks!
In Help menu, the internet address for 'L-Py Website', is incorrect
Hi,
Is there a way of accessing the turtle commands from Lpy? E.g. if we want to use turtle.write() to label things during modelling is there a way that this can be done?
Many thanks!
Hi, I am trying to use input() in our code in the L-Py GUI. However when I click run, it lags and endlessly tries to load. Eventually I just press ^C in the terminal to interrupt it. I am on macOS Monterey with L-Py on python 3.9. On another laptop (Windows) with a python 3.8 version of L-Py, it gives an error message about sys.stdin (might be another name, can't quite remember but can confirm it was "sys").
Is this normal? I had thought pure python code should work. Is there any alternative method?

Dear all,
After running the conda installation for lpy on Linux platform. I have the following error :
Preparing transaction: done
Verifying transaction: done
Executing transaction: failed
ERROR conda.core.link:_execute(481): An error occurred while uninstalling package 'defaults::certifi-2018.1.18-py27_0'.
OSError(13, 'Permission denied')
Attempting to roll back.

Could I have some suggestions ?
I thank you in advance for your help,
Didier
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.
OS:ubuntu20.04
I installed the binaries using conda following the instructions in the doc and everything worked well until I restarted my computer. After that I could not run the lpy normally.
When I type conda activate lpy, that's ok. However, when I enter lpy, the lpy main window would flash and close soon with the terminal telling me:
Segmentation fault (core dumped)
I have no idea about what's going on...
Hi there! Thank you for your work on this project!!!
I get ValueError:invalid mode: 'rU' when i try to open the examples in the models folder.
Is there something i can try to fix it?

The .lpy interpreter says that in the following example is an indentation error, caused by the comments. I would expect that the interpreter ignores them.

l = Lsystem("test.lpy")Hi all,
I have a lpy file on Windows and I would like to add this file in a documentation using Sphinx but don't know how to make the link to a non .py file
TY
Use openalea.plantgl rather than the old vplants.plantgl
I'm trying to install lpy using conda on one existing environment
conda install openalea.lpy -c fredboudon -c conda-forge
and one new environment:
conda create -n lpy openalea.lpy -c fredboudon -c conda-forge
For the existing environment, strangely after installation and calling "lpy", there is nothing happening. However, for the new environment, "lpy" works and the visual lpy editor appear.
What did I do wrong for the existing environment?
OS: Windows 11
I installed the binaries using conda following the instructions in the doc.
But when I input command line in python shell panel and type enter, the user interface crashed.
I recently ported my Python2 code involving OpenAlea mtg and lpy libraries into Python3. With Python3, the Lsystem.animate() now can't invoke PlantGL viewer to show the Lpy animation, instead it shows a blank PlantGL canvas. It was working just fine in Python2 though. Any advice on how to resolve this?
FYI, Lsystem.plot() plot the image just fine in both Python 2 and Python 3 version.
from openalea.lpy import *
lsystem = Lsystem("massart.lpy")
for lstring in lsystem:
scene = lsystem.sceneInterpretation(lstring)
scene.save("test.ply")It did save the test.ply but I can't open it due to error saying Error reading 'vertex_indeces' of 'face' number 8525.
Hello, I have installed anaconda and lpy as instructed, I created the environment and activated it, but when I type in lpy nothing happens. do I miss something? I do I access the visual editor?
Thank you very much!

After installing lpy in conda environment named my_env, runing :
activate my_env
lpy
launch 'call activate openalea'
...which is a bit weird I suppose
Hello,
I am using a Lsystem and I would like to do a sensitivity analysis.
I wrote a python script to execute the lpy file and I want to get some attributes of the Lsystem back (for instance a dictionnary).
Presently, I use MyLsystem.derive() to execute the .lpy file but no access to attributes is possible. It seems close the Lsystem.
Is there an other method than .derive() to use ?
Kind regards,
Simon
Hello,
Using the command from the documentation conda create -n lpy openalea.lpy -c openalea throws an error on Ubuntu 20.04.
The error :
UnsatisfiableError: The following specifications were found to be incompatible with your CUDA driver:
- feature:/linux-64::__cuda==10.2=0
Your installed CUDA driver is: 10.2
After some snooping around, it seems the error is not directly related to CUDA driver but rather to other unsatisfied dependecies. I tried some of the workarounds proposed in issue #12 , but to no avail.
Any advice on how to install on a recent Ubuntu install ?
Regards,

Hi,
I was having trouble running lpy because qhull wasn't installed. Here is how I got it working:
Created a conda environment:
conda create --name lpy python=3.9
activated the environment:
conda activate lpy
installed quhull:
conda install qhull
installed lpy:
conda install openalea.lpy -c fredboudon -c conda-forge
