[Matplotlib-users] matplotlib.lines.Line2D object at 0x283d310 - strange error

[ninjasmith <hen...@gm...>]

Hi,

I'm a bit new to matplotlib and python.  I'm running ubuntu 64bit.  whenever
I try and do anything with matplotlib I get an error similar to above.  it
still works, i.e. when I run the show() command the plot will appear but all
matplotplib commands return an error similar to above. for example

In [15]: plot(a)
Out[15]: [<matplotlib.lines.Line2D object at 0x28487d0>]

In [16]: figure(2)
Out[16]: <matplotlib.figure.Figure object at 0x2ddc150>

Interestingly when I run from SPE and choose 'execute in shell' I get the
following errors. 
11:32:29: Can't load image from file
'/usr/share/spe/_spe/skins/default/home.png': file does not exist.
11:32:29: Can't load image from file
'/usr/share/spe/_spe/skins/default/back.png': file does not exist.
11:32:29: Can't load image from file
'/usr/share/spe/_spe/skins/default/move.png': file does not exist.
11:32:29: Can't load image from file
'/usr/share/spe/_spe/skins/default/zoom_to_rect.png': file does not exist.

my simple script is as follows

import numpy, scipy, wave, struct
from pylab import *
from scipy import *
import wavFunctions
print(dir(wavFunctions))
#def readwave(wavfilename):

readwave=wavFunctions.readwave
    
#	w=wave.open(wavfilename,'rb')
#	(nchannel, width, rate, length, comptype, compname) = w.getparams()
#	frames = w.readframes(length)
#	data = numpy.array(struct.unpack("%sh" %length*nchannel,
frames)).reshape(length,nchannel)
#	return data


audio = readwave("/media/LACIE/bfd
rendered/edited_single_hits/ayotte_snare_keplinger_hit.wav")
print audio
print audio.size
plot(audio)



fft_audio=fft(audio)
print fft_audio
figure(2)
plot(abs(fft_audio))
show()


11:32:29: Can't load image from file
