使用图像显示matplotlib.pylab使用python ide？

Question

我试图在photutil中运行示例

除了台词，一切都很好

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

这不会引发异常，但不会显示图像。我使用eric ide。在

Answer 1

# need to use matplotlib inline if want to show at jupyter Notebook
%matplotlib inline
plt.imshow(image, cmap='gray_r', origin='lower')
plt.show()

Answer 2

您需要稍后致电plt.show()。在

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 show() 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.
