Question

我创建并运行了一个非常简单的python代码来显示直方图。直方图显示成功，但程序永远不会完成。你能帮忙吗？

单击Ctrl和C，将显示以下消息。

File "hist_ex.py", line 9, in <module>
plt.show()
File "/Users/myusername/.pyenv/versions/anaconda3-4.4.0/lib/python3.6/site-packages/matplotlib/pyplot.py", line 254, in show
return _show(*args, **kw)
File "/Users/myusername/.pyenv/versions/anaconda3-4.4.0/lib/python3.6/site-packages/matplotlib/backend_bases.py", line 218, in show
cls.mainloop()
File "/Users/myusername/.pyenv/versions/anaconda3-4.4.0/lib/python3.6/site-packages/matplotlib/backends/backend_tkagg.py", line 1078, in mainloop
Tk.mainloop()
File "/Users/myusername/.pyenv/versions/anaconda3-4.4.0/lib/python3.6/tkinter/__init__.py", line 557, in mainloop
_default_root.tk.mainloop(n)
KeyboardInterrupt

这是我的python代码。

import numpy as np
import matplotlib.pyplot as plt

x = np.random.normal(50, 10, 1000)

plt.hist(x)
plt.show()

这种情况正在发生，因为您处于非交互模式......

尝试使用

plt.show(block=False)

显示直方图代码永远不会结束
