我试图在photutil中运行示例

一切都很好,除了线

plt.imshow(image, cmap='gray_r', origin='lower')

它不会引发异常,但不显示图像.我使用eric ide.

解决方法:

之后你需要调用plt.show().

从Matplotlib FAQ：

When you want to view your plots on your display, the user interface backend will need to start the GUI mainloop. This is what 07001 does. It tells matplotlib to raise all of the figure windows created so far and start the mainloop. Because this mainloop is blocking by default (i.e., script execution is paused), you should only call this once per script, at the end. Script execution is resumed after the last window is closed.
