[Matplotlib-users] ImportError: cannot import name rcParams

[Brian O. <bri...@gm...>]

Hi All,

I'm running into the following error when I try to run any of the matplotlib
examples:

$ python anim.py
Traceback (most recent call last):
  File "anim.py", line 19, in <module>
    import pylab as p
  File "C:\Python25\Lib\site-packages\pylab.py", line 1, in <module>
    from matplotlib.pylab import *
  File "C:\Python25\Lib\site-packages\matplotlib\pylab.py", line 206, in
<module>
    from matplotlib.numerix import npyma as ma
  File "C:\Python25\Lib\site-packages\matplotlib\numerix\__init__.py", line
20, in <module>
    from matplotlib import rcParams, verbose
ImportError: cannot import name rcParams

I'm using the latest versions of matplotlib and numpy, ActivePython 2.5 (all
for Windows XP).  Any help would be appreciated.

Regards,
Brian.

Hi,

I'm getting the following error when trying to create a plot with
matplotlib.  I am using matplotlib-0.91.2 on CentOS 4 with python 2.3.
We are running it with mod_python and Apache in a web service
configuration.

File
"/usr/lib/python2.3/site-packages/matplotlib-0.91.2_r0-py2.3-linux-i686.egg/matplotlib/dates.py", line 88, in ?
    import matplotlib.ticker as ticker

  File "/usr/lib/python2.3/site-packages/matplotlib-0.91.2_r0-py2.3-linux-i686.egg/matplotlib/ticker.py", line 116, in ?
    from matplotlib import verbose, rcParams

ImportError: cannot import name rcParams

This error has only appeared since we started using Apache 2.2 instead
of 2.0.  I can do the import just fine from the command line in a python
2.3 shell.  Any ideas?

Thanks,
Rich

My guess is that somewhere on your system you have an old matplotlib
installed that had the namespace package declared, and this is fouling
up your import.

There was a bug in our windows installer.  Please remove the old mpl
install, grab the latest installer from the download site, and try
again.

Sorry for the trouble!

Thanks,
