Anyone know how to get it working? Unfortunately it seems by default specgram's code wants to generate an image, which I have no use for, only the data behind the image. The error I get is:

_tkinter.TclError: no display name and no $DISPLAY environment variable

您可以设置一个 matplotlib 后端，它不需要附加显示：

import matplotlib
matplotlib.use('pdf')

这些行应该在导入pylab.
