visualea's Issues

Missing dependencies during win64 anaconda installation

Hello,

On win64 platform with anaconda installation of visualea from openalea channels :

conda create -n visualea python
activate visualea
conda install -c openalea openalea.visualea

I'had execution error when a launch visualea :

ipython
from openalea.visualea.visualea_script import start_gui
start_gui()

Resulting error like :

ImportError: You must install pyqt-tools due to pyqt package absence
ImportError: No module named rich_ipython_widget due to qtconsole absence
AttributeError: 'module' object has no attribute 'QTextEdit' due to pyqt version 5

So I fix my problem with :

conda install -c openalea pyqt=4.10.4
conda install -c openalea qtconsole

When running visualea, there is an error:

Update README

Jupyter/Ipython shell is not working in VisuAlea

To reproduce the problem, type:
import os

Nothing happen (error messages on the console).

Error when using send to console

In VisuAlea, when running sendtoconsole, the following error is raised:

  File "/Users/pradal/devlp/git/visualea/src/openalea/visualea/graph_operator/__init__.py", line 115, in wrappedGOPNoBool

Bug when return iterable with one element

Hi, I encounter problem :

def test_bug_0():  
    return {"A": 0, "B": 1}

def test_bug_1():
    return {"A": 0, "B": 1, "C": 2}

def test_bug_2():
    return {"A": {0: 42, 1: 21}, "B": 1, "C": 2}

def test_bug_3():
    return {"A": {0: 42, 1: 21}}

def test_bug_4():
    return {"A": {0: 42}, "B": {1: 21}}

test_bug_3() bug and return :

Traceback (most recent call last):

Worst with a collection.defaultdict like :

def test_bug_5():
    d = collections.defaultdict(dict)
    d["A"][0] = 42
    return d

don't throw error; just return a empty dict {}

Same for you ?

Visualea is not working on windows and Python 3.12

1. Conda package define noarch : entry_points are not valid
2. Debug Visualea for 3.12

standalone application

• a workflow exported with a node marked as user application
• run the app.py with python
• in tab "user applications" click the button "Widget"
• get error AttributeError: 'GraphOperator' object has no attribute 'vertex_open'

And indeed, GraphOperator has no vertex_open. See line 165 in src/openalea/visualea/compositenode_widget.py

What was the purpose of it

'visualea' 不是内部或外部命令，也不是可运行的程序 或批处理文件。

我使用这个命令安装，conda create -n visualea_tuto -c openalea openalea.visualea openalea.components openalea.plantgl boost=1.66 -c openalea/label/unstable
conda activate visualea_tuto
然后运行visualea，提示not command，'visualea' 不是内部或外部命令，也不是可运行的程序
或批处理文件。

Visuala: python 3, Qt5, WIP to be able to open the main window, issue with connect

In order to have the main window of visualea ( #14 ) open the following lines have been commented or modified:

• visualeagui.py: l. 124 modified
  splash.showMessage(message, QtCore.Qt.AlignCenter|QtCore.Qt.AlignBottom) changed to splash.showMessage(message)
• mainwindow.py: l. 145 commented
  self.connect(self.tabWorkspace, QtCore("contextMenuEvent(QContextMenuEvent)"), self.contextMenuEvent)
• node_treeview.py: l. 211 commented
  l.sort(item_compare)# (lambda x,y : cmp(x.get_id(), y.get_id())))
• node_treeview.py: l. 914-915 commented
  self.expanded(QtCore.QModelIndex).connect(self.expanded)
self.collapsed(QtCore.QModelIndex).connect(self.collapsed)

All these modifications are referenced in the code with # F. Bauget 2023-01-18.

Then, connect management is one major issue.

export to application not working

Port to Qt5 not finished

nodes alignments not working, none of them, even with the python2 version

Missing python base function in visualea like getitem

Tested with win64 conda installation :

conda create -n visualea python
activate visualea
conda install -c openalea openalea.visualea pyqt=4.10.4 qtconsole
visualea

And with "git clone" + "python setup.py install" on openalea repository : core, vpltk, grapheditor, misc, oalab, visualea

Installation issues

Hi, I've been trying to install and run visualea but I've been running into issues. I was on macOS Mojave but I've tried updating to the newest macOS Monterey version 12.3.1 and am still running into the same issues.

For example, I tried conda create -n openalea -c conda-forge -c openalea openalea.visualea. This went through without issues but when I typed visualea, I received the following error message:

Traceback (most recent call last):
File "", line 1, in

UnsatisfiableError: The following specifications were found

If python is on the left-most side of the chain, that's the version you've asked for.
When python appears to the right, that indicates that the thing on the left is somehow
not available for the python version you are constrained to. Note that conda will not
change your python version to a different minor version unless you explicitly specify
that.

The following specifications were found to be incompatible with each other:

Output in format: Requested package -> Available versions

---

Another type of error I've previously gotten when entering "visualea" into the terminal was "ImportError: No module named asyncio" since I'm using python2.7 for this installation. When I try using python3 when installing visualea I'd get error messages about conflicts etc. but I believe asyncio is a python3 module? I have since deleted the env which gave that error though.

I also tried this on a Linux server and I ran into same/similar error messages.

Update CI to github actions

gui not starting after install with conda on win64

Hi,

I just test the visualea conda intall on my win64 (conda install -c openalea openalea.visualea).
When I tried runing visualea, nothing append.

I investigate a little bit more launching from ipython using:

from openalea.visualea.visualea_script import start_gui
start_gui()

I got a first error asking for openalea.oalab (for the interpreter). Is this dependency expected ?
After (conda) install of oalab, I got a second message for importing openalea.misc (same question ?)
After installng openalea.misc, I got the following error

That's all folks !

SyntaxError: invalid syntax (trunk_parameters.py, line 51)

I have installed openalea on a windows 10 machine.

I am not a python expert.
I use Python 3.9
Installed visualea but could not get it to run with the command "visualea" as stated in the documentation.

So i went to my ......\anaconda3\envs\openalea\Scripts directory.

There i run

python visualea

I get the program started but when i try to open Demo_WeberPenn i get:

Installation/running visualea

Hi, I'm having trouble in running visualea/openalea in general. I've installed OpenAlea (Windows) through https://openalea.readthedocs.io/en/latest/install.html#openalea-installation. Then I wanted to add the package of Visualea through https://anaconda.org/search?q=visualea, but ran into the same problem that my python version was to 'new' for Visualea. So I brought the version back to 2.7.15 in the anaconda navigator, but now I'm having several problems:

• The 'pglviewer' command is not recognized in the anaconda command prompt anymore --> PlantGL doesn't appear
• A window of visualea doesn't appear when typing 'visualea'
• Several times that the following error occurs: Microsoft Visual C++ Run Time Library: Run time error! Program: C:\ Users\u0158557\Anaconda3\python.exe R6034: 'An application has made an attempt to load the C runtime library incorrectly . Please contact the application's support team for more information
• Looking into the packages installed in this environment, it is quite different from the packages that were installed before installing visualea

I have no experience with the program, so if someone can give me the right steps that I have to undertake to get OpenAlea up and running (regarding packages, versions,... in Windows), this would be quite helpful.
Thank you in advance
