Re: [Matplotlib-users] problem importing pyplot/pylab on mac os x 10.4.11

[Karianne H. <kar...@as...>]

Hi,

I changed the script to what you suggested and this is the output:
[karianneholhjem:~] karianne% python bla.py --verbose-helpful
$HOME=/Users/karianne
CONFIGDIR=/Users/karianne/.matplotlib
matplotlib data path /Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/matplotlib/mpl-data
loaded rc file /Users/karianne/.matplotlib/matplotlibrc
matplotlib version 1.0.0
verbose.level helpful
interactive is False
units is False
platform is darwin
Bus error

I get the same output when commenting out either line 2 or 3. 
(/Users/karianne/.matplotlib/matplotlibrc is just a link to 
/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/matplotlib/mpl-data/matplotlibrc 
as was in my previous output.)


Regarding numpy - what you say is intersting. I couldn't find any such 
problems in my google-searches. I am running version 1.2.1:
[karianneholhjem:/] karianne% python -c 'import numpy; print numpy.__version__'
1.2.1

I couldn't find the version requirements in the README file so I probably 
found the wrong README
(/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/numpy/README.txt). 
It did provide a way of testing numpy, I don't know if it's interesting 
but here is the output:

[karianneholhjem:/] karianne% python -c 'import numpy; numpy.test()'

OK (KNOWNFAIL=1)

Is there any more information I can provide to give you clues as of why 
pyplot and pylab aren't working? Thank you for your help so far, I did a 
course on python/numpy/matplotlib and I would really like to use 
matplotlib as it is a really powerful plotting tool!

cheers,
Karianne
