pombreda / pythonxy Goto Github PK

What steps will reproduce the problem?
1. There is no vtkGdcmReader class in the current release of gdcm. This is
a very helpful class to work with vtk.Probably while building the vtk
support should be turned on.

What about only one entry labeled "Install for all users" (unselected by
default)? (instead of the choice between all users and current user)

When using Python from command line (not via Pythonxy console), importing
matplotlib can fail if scipy is imported first.

There are two common ways to arrive at this:

- running Python directly from cmd.exe
- running Python scripts by double-clicking them

The latter is probably the more common use case. It would be nice to
distribute scripts that produce output via matplotlib.

What occurs is:

C:\Documents and Settings>python

But it works if the order of the imports is reversed:

>>> from scipy import *

Operating system: Windows XP SP 3. Python(x,y) 2.0.5.

please add the Notepad++ shell extension to the installer:
If you install the Notepad++ independently, a option "Open with Notepad++"
is added to the context menu of the explorer.
I uninstalled the standalone version of Notepad++ in order to use the one
included with PythonXY. But now this useful extension is missing.

Also, I noticed that at installation time, a lot of files in the pythonxy
directory are write protected.
Therefore, the user can  not change the settings of Notepad++. May this
also be changed?

Thanks in advance!

Can you add winpdb for your future release?
It's an excellent multiplatform debugger

Hi, Pierre.

I just downloaded and installed Python(x,y) 2.1.0 Full Edition for myself
as a single user under Win XP/Pro SP 3. I had previously installed 2.0.3
which I allowed the new installer to automatically uninstall.  After
installation, I notice that my PATH environment variable's contents have
been truncated.  I don't have a copy of the previous contents, but the new
contents are a string of length 297 characters (much shorter than before): 
c:\TeXLive\bin\win32;C:\Program Files\pythonxy\python;C:\Program
Files\pythonxy\python\DLLs;C:\Program
Files\pythonxy\python\Scripts;C:\WINDOWS\System32;C:\Program
Files\pythonxy\python\Lib\site-packages\PyQt4;C:\Program
Files\pythonxy\console;C:\Program Files\Common Files\Intel\Shared Files\idvc

Notice that the final entry is now incomplete.

Thanks,
Peter Simon

It would be nice to have some information about the compilation settings
that are used for the components of pythonxy. This way, custom components
can be integrated by others.

As an example: If working on a Linux and Windows system at the same time,
the ITK package should have the same python compilation settings (Using
WrapITK? Which functions / datatypes are wrapped?) as the version that
comes with pythonxy. The same applies vice versa: In some situations it
would be nice to adjust the settings of e.g. ITK in pythonxy based on some
other installation in order to keep them in sync.

It would be convenient to have all programs contained in the PythonXY
distribution into the Startmenu folder:
* Notepad++

What steps will reproduce the problem?
1. install the Python(x,y)Full Edition 
2.
3.

What is the expected output? What do you see instead?
Expected output: updated PATH settings
Output in fact: Erase all elder items in the PATH settings

What version of the product are you using? On what operating system?
2.1.5

Please provide any additional information below.

Many useful plugins are already available at
http://pypi.python.org/pypi

I write a small script which could be used to fetch a list pf packages from
that location after installing Python (XY). This be a alternative to
downloading plugins for users connected to the net.

Maybe it could be included into the installer.

Not that it will be neccessary for users behind a corporate firewall to set
the http proxy.

What steps will reproduce the problem?
1. lancement de l'interface Python(x,y) Home
2. click sur le bouton C ('ouvrir la console sélectionnée dans Console 2')
3. un message d'erreur apparaît.

What is the expected output? What do you see instead?


What version of the product are you using? On what operating system?
2.1.4 full edition

Please provide any additional information below.
C'est un message de Laurent Videau

PythonXY already comes with the Mingw32 Compiler.

According to
http://www.scipy.org/Cookbook/CompilingExtensionsOnWindowsWithMinGW
one needs to configure the distutils to work with the compiler before being
able to comile python modules on windows.

This should be already done by the installer.

Install the attached file to:
pythonxy\python\Lib\distutils\

What steps will reproduce the problem?
1. Unzip the Stani's Python Editor (SPE-0.8.4.c) downloaded from
http://pythonide.blogspot.com/  (no installer needed)
2. Launch the SPE.py file (python SPE.py)


What is the expected output? What do you see instead?
This program (my actual favorite Python Code Editor) run normally with the
Python.org distribution. It is a program written in Python and using
wxPython. I received this error message after trying with Python(x,y):
"wxPython Upgrade Needed. This application requires a version of wxPython
greater than or equal to 2.5.4.1, but a matching version was not found. You
currently have these version(s) installed: " ... (jpg on attached file)

What version of the product are you using? On what operating system?
I installed the python(x,y) 2.1.4 Full Edition with the wxPython 2.8 and
many-many other modules. Windows XP SP3.

Please provide any additional information below.
The wx appear correct when I import it from the python command line, and
the wx.__version__ is higher than 2.8. Rapid inspection of the SPE's source
code contains calls of the wxversion.getInstalled() function from the
Lib\site-packages\wxversion.py. Unfortunaly this function lies and returns
an empty list, so the program think there is no wx installed. 
Maybe the problem arise from the fact that the python installation is moved
in the "program file" directory with this distrib. I tried to add \wx and
\wxPython in the sys.path (they where absent) but it doesn't change. I am a
python beginner thought, I have never used wx and I dont know how to fix it. 

The included visual module is VPython 4.beta26, which was released in Feb
2008.  They abandoned the 4 series, and currently have a release candidate
for version 5.  You should consider moving over to the 5.0 series. 

Purpose:
Some users are working in fields with specific interests. They require
packages which cannot be distributed with the main distribution.
It would be nice to have the possibility to update and install them all at
once from local directories or from http://pypi.python.org/pypi

The approach could be using a script which fetches the names of these
packages from a list contained in a text file. It would then call
EasyInstall  to get and install packages from a remote repository or local
directory.

Another option would be to use Enstaller
(https://svn.enthought.com/enthought/wiki/Enstaller)

Another approach could be to let users contribute "addons" just like the
plugins for Easyeclipse
(http://www.easyeclipse.org/site/plugins/index.html) which could then be
installed after PythonXY is installed.

Please add also the directory:
C:\program files\pythonxy\python\Scripts

It contains some important python scripts and executables.

Everything is in the title...

Python(x,y) doesn't lauch a compile step of all .py file into .pyo.
The side effect is that small script takes longer time to run without .pyo.
I've tested your compile script seems to work.

I just started MayaVi, loaded a volume (e.g. doc...MayaVi2\data\heart.vtk),
selected the "Volume" renderer (volume gets rendered in the upper right
corner).

However:

- The color map displays a wrong (completely blue) default color scale.
-  When changing any values in the color transfer function, the volume
disappears in the upper right viewer.

Is there a new version that could eliminate the bugfix?

Regards,

              Fabian

Please add the address:
http://code.google.com/p/pythonxy
to the offical website http://pythonxy.com/

Maybe there could be a page called contribute.

The GNU Debugger gdb would be helpful as an optional package
for debugging with eclipse as the integration with the latest CDT is
working really well. An installer can be downloaded here:
https://sourceforge.net/project/showfiles.php?group_id=2435 -> GNU
Source-Level Debugger -> Current Release. This version is working
here... 

What steps will reproduce the problem?
1. Downloaded xyweb-1.0.1.exe
2. Tried to start the program.
3. Got a spyware warning that the file was trying to install the malware
trojan.autoit

What is the expected output? What do you see instead?


What version of the product are you using? On what operating system?
xyweb-1.0.1 Windows XP Downloaded from http://www.pythonxy.com/download.php

Please provide any additional information below.

What steps will reproduce the problem?
1. In the Python(x,y) main window, click the NetworkX 's python help button
2. close the prompted help IE window and the pydoc window
3. try to open scipy's python help by clicking the python help button. The 
Python(x,y) main window doesn't response anymore.

What is the expected output? What do you see instead?
It should reopen an IE window to show the html help for scipy. But the 
python(x,y) main window doesn't response and no help window is prompted. I 
have to force closing the python(x,y).

What version of the product are you using? On what operating system?
Python(x,y): 2.1.6 
OS: windows xp sp2, IE6

Hi, Pierre,

just played with two python-apps that come with wxPython: (i) PyCrust.py,
(ii) PyAlaCarte, both can be found in

\pythonxy\python\Lib\site-packages\wx\py

and can be started stand-alone.

The first is an interactive shell similar to IPython, it has a history
window (like MATLAB has) and IPython's history function (pressing Ctrl+Up
instead of Up only) and some nice features like
Scintilla-Command-Completion (Popping up combo-box, like in Intellisense),
function documentation that stay in a window, and a namespace browser for
local variables (like MATLAB has).

PyAlaCarte is a light-weight Python editor that does not require a
workspace like Eclipse does and it has features similar to PyCrust. Both
are not perfect, i.e. IPython's "run" is missing in PyCrust, but they are
very handy.

There is also an IPython shell that runs in wxPython, but for this purpose,
there is already IPython in the Command++-shell.

If there are similar tools that do a better job, then of course I'd love to
be convinced ;-)


Regards,

       Fabian

OS: Windows Vista
Configuration: "My Documents" has been moved to another location, say D:\
for example

Problem: Python/Eclipse workspace folder is set by the main installer to
"C:\Python", instead of "D:\Python"

Side effect: if one choose "Custom Directory" in the main installer, the
workspace folder default value is "\Python" (invalid location).

Fortran (77/90) is quite extensively used language in scientific computing.
It might be useful to have the GFortran compiler available out-of-the-box
in Python(x,y) distribution, similarly as Mingw is.

AFAIK, Gfortran is not included in the Mingw distribution. However, it
appears that the GFortran windows binaries available here:
http://gcc.gnu.org/wiki/GFortranBinaries work nicely enough. (They however,
contain a copy of the proper version of gcc, which I think is not the same
as that included with plain Mingw.)

In Custom Edition, there is no point to leave the configuration selection
(recommended, full, custom) because there is no plugin to select or unselect.

When installing PythonXY as Administrator for all users the initial Eclipse
workspace for the other users is set to following path:
c:\documents and settings\Administrator\My Documents\My Documents

Of course this can be changed later withing Eclipse. But it affects also
the application link in the PythonXY Home Window. If I manually create a
new workspace the folder will not have a Python overlay and PyDev is not
selected as default perspective.
one would also need to change:
\pythonxy\startups\default.py

Maybe there could be a first run script which determines the users Home
directory or let him configure the desired path to the default workspace.

Add matplotlib 0.98.3 new documentation (sphinx-generated) to Python(x,y)
mpl plugin.

Some issues when reinstalling Eclipse are due to the fact that the
".metadata" subfolder (default workspace directory) was not removed during
uninstall/install.

Hi,

today I tried 2.1.2 FE. It seems that (even with complete installation),
the ipy_profile_mlab cannot be found when starting IPython (mlab) from the
Python(x,y) frontend application.

Any hints?

As both ITK and VTK have been included in pythonxy, it would
be great if they could work together. Actually, connecting ITK and VTK
is possible if ITK is compiled with ITK_CSWIG_CONNECTVTKITK set to ON.
Also, the application ConnectVTKITK has to be built, according to the
example in ITK/Examples/Visualization.

There are some code checking tools available for python:

* http://svn.browsershots.org/trunk/devtools/pep8/pep8.py
* http://www.logilab.org/project/name/pylint
* http://pychecker.sourceforge.net/
* https://code.launchpad.net/pyflakes

pylint can even be integrated into Eclipse.

It would be nice to have sich tools delivered with PythonXY

Hello,
Reinteract wouldn' start on my computer.

If I start it from the console, there are no error messages:

First I would like to congratulate you for the work of integrating Python
Libraries for the scientific community! It is a great idea which will
develop for sure the use of Python.
I have however an issue with the Python(x,y) 2.0.5 on Windows XP Basic
concerning the configuration of the Qt designer. There seems to be a
general problem with the location where this program is looking for components:
- The help does not work, the programs look for the
C:\Qt\4.4.1\assistant.exe program whereas Qt was installed in the
python\Lib\site-packages directory
- The program does not find the plugins. Obviously it looks also for the
same c:\Qt\4.4.1 directory, as when I did copy the plugin there (after
creating the directory) the plugins were loaded
- I cannot load custom widget into the designer with the script
Python25\Lib\site-packages\PyQt4\examples\designer\plugins\plugins.pyw : no
errors appear but no custom widget are loaded either.

What steps will reproduce the problem?
1. Install the 2.0.5 Basic Python(x,y) on Windows XP (no python installed
before). I used custom directory installation: C:\Python25\
2. Open the Qt4/Designer program
3. Try to launch the help / check that no plugins are loaded

What is the expected output? What do you see instead?
Help is not working/no plugin

What version of the product are you using? On what operating system?
Python(x,y) 2.0.5 Basic Edition on windows XP

I just upgraded from 1.3.x to 2.0.5.
The default editor associated with .py files was changed to Notepad++ from

I have to manually create it, it's in <Python directory>\Lib\idlelib\idle.bat

Suggestion:
- ask users during install whether they want the default editor associated
with .py to be IDLE or Notepad++. (Keep IDLE the default, not Notepad++)

Motivation: IDLE is the lowest-common-denominator editor, it's guaranteed
to exist with every Python install, non-scientific or scientific. People
can always
change the default to Notepad++ if they prefer.

Okay, this is hopefully the last irritating which from my side - sorry for
posting so many items in the last days; but remember that I do it for
improving pythonxy and not for "creating work packages":

Today, I finally realized that connecting ITK and VTK is primarily
supported by a (WrapITK-based) project
"ITK/Wrapping/WrapITK/ExternalProjects/itkVtkGlue".

It would be great if this project could be included in pythonxy as it is
hard to connect ITK and VTK manually as this would either require custom
"hacks" or a complete ITK/VTK installation for compiling the project
individually (and the complete installation is not included in pythonxy).

Thanks!

Hi,

there are some issues with the newest update from 2.0.4 to 2.0.5:

- After updating, some new program icons can be found directly in the top
start menu folder, even though a different start menu folder has been set
in the original installation procedure.

- The MayaVi examples still don't work (boy, standalone, and probably many
more)

However, VTK examples work now :-)

Regards, Fabian

What steps will reproduce the problem?
1. import vkt throws some error that it cannot load some DLL
2.
3.

What is the expected output? What do you see instead?


What version of the product are you using? On what operating system?


Please provide any additional information below.

The following modules are still lacking in the documentation selector:
* Plotting
 - PyQwt
* GUI
 - Easygui
 - wxPython

This will be supported in 2.1.5.

In 2.1.4, the Python(x,y) CE installer doesn't automatically untick a
component if one of its dependency installers is missing in the
subdirectories "python", "eclipse" or "other".

Hi Pierre,

Sorry to bother with such cosmetic feature,
but could you, please, by default turn on the "line number" displaying
in the eclipse editor ?

Windows -> Preferences -> General -> Editors -> TextEditors ->
ShowLineNumbers

Thanks,
Cheers,
Nicolas. 

What steps will reproduce the problem?
1. Start any python(x,y) interactive console

What is the expected output? What do you see instead?
Expected: Console with white bg and black font showing ipython
Happened: Black screen, black font (see attachment)


What version of the product are you using? On what operating system?
Vista Business 64bit, python(x,y) 2.1.4 and 2.1.5

Please provide any additional information below.
Console worked on 2.1.4, updated to 2.1.5 then the error occured.
Uninstalling 2.1.5 and reinstalling 2.1.4 did not help.
Tried switching color settings, didn't help either.
Console is working, when I enter code (eg pyplot.figure()) the figure opens
up. When I click "show command window" the windows command window opens and
shows the correct content. So it's a console bug.
