Question

enter image description here我正在学习如何使用python绘制一些3D图片。当我输入plt.show()时，会出现错误。

ValueError: max() arg is an empty sequence

但是，我尝试在IDLE上运行它，但没有错误。使用PyCharm时应该如何解决此问题，非常感谢您的帮助。

import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D


x = np.linspace(-6 * np.pi, 6 * np.pi, 1000)
y = np.sin(x)
z = np.cos(x)


fig = plt.figure()
ax = Axes3D(fig)


ax.plot(x, y, z)


plt.show()

我在Python控制台中尝试过，只有运行plt.show()时才会出现错误。

plt.show()

ValueError: max() arg is an empty sequence

在PyCharm中使用plt.show（）时'ValueError：max（）arg为空序列'
