我一直在试验 SPy (Spectral Python)，在 Mac 上使用 PyCharm。我一直在错误地遇到错误，但就目前而言，我完全被这个错误所困扰：

程序输出：

/System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7 "/Users/pkillam/PycharmProjects/untitled/SPy Experiments"
/Library/Python/2.7/site-packages/spectral/spectral.py:198: UserWarning: Unable to import or configure pylab plotter.  Spectrum plots will be unavailable.
  'will be unavailable.', UserWarning)

    .
    .    #normal output
    .

这是代码，主要来自此处的 SPy 指南：http ://www.spectralpython.net/user_guide.html

import matplotlib
matplotlib.use('WX')
from spectral import *

img = open_image('92AV3C.lan')
print img.__class__
print
print img
print
print img.shape
pixel = img[50,100]
print
print pixel.shape
band6 = img[:,:,5]
print
print band6.shape
print

arr = img.load()
print arr.__class__
print
print arr.info()
print
print arr.shape

view = imshow(img, (29, 19, 9))

有任何想法吗？

好的，我解决了这个问题。事实证明，自从我使用自己的包管理器更新 PyCharm 以来，PyCharm 一直在尝试访问两个不同版本的 matplotlib。我通过删除其中一个版本来解决这个问题，但是，后来我继续遇到一个又一个问题。

这段代码现在完全可以工作了，因为我转移到了 Anaconda 的 Spyder 而不是 Pycharm，它更容易使用！

谢谢大家在评论中提供帮助。
