Я изучаю библиотеку mpld3 и не могу понять, как создавать трехмерные диаграммы рассеяния. С Matplotlib я бы сделал:
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
ax.scatter([1],[5],[7])
plt.show()
Точно так же с mpld3 я пробовал (в блокноте Jupyter): импортировать matplotlib.pyplot как plt из mpl_toolkits.mplot3d import Axes3D import mpld3
mpld3.enable_notebook()
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
ax.scatter([1],[5],[7])
mpld3.display(fig)
и я получаю сообщение об ошибке
TypeError: array([ 0.94, 1.06]) is not JSON serializable
Любые идеи?
