[Matplotlib-users] New user's question --- first run --- everything seems fine, got error msgs.

[<fri...@gm...>]

Dear all,

I'm an astronomy major college student in Beijing who recently switched to
Python for most of his homework in numeric analysis and data visualization
(and really loving Python). I run Python 2.5 with NumPy, SciPy
and matplotlib on a Fedora 7 Linux system. The matplotlib on my computer was
build from source but most of the required dependecies (incl. wxPython,
gtk2-devel things, etc.) were installed from the "official" Fedora
repository via yum. During compilation of matplotlib I set the BUILD_WXAGG
variable to 1 and left everything else untouched.

The compilation was smooth but the first test run seems not. After invoking
ipython with -pylab parameter I received the warning (and welcome) messages:

/usr/lib/python2.5/site-packages/IPython/Shell.py:709: DeprecationWarning:
The wxPython compatibility package is no longer automatically generated or
actively maintained. Please switch to the wx package as soon as possible.

Welcome to pylab, a matplotlib-based Python environment.
For more information, type 'help(pylab)'.

I don't understand what was said by the Deprecation Warning message. The
wxPython on my computer is up-to-date.

Then I threw a test command to ipython and things seem to be wrong again. A
typical session goes like this:

In [1]: # This is just a test plot. It generates a figure in the GUI with
some warning message.

In [2]: plot([1, 3, 8, 0])

** (python:15301): WARNING **: IPP request failed with status 1030

** (python:15301): WARNING **: IPP request failed with status 1030
Out[2]: [<matplotlib.lines.Line2D instance at 0x971648c>]

In [3]:


The correct figure was generated in a GUI but error messages pop
up whenever "plot" is used.

Currently I've got no idea about either warning message. They certainly told
me something but I can't even make sure whether there are things going
wrong! *shrug* So any hints?

Thanks in advance

Cong.
