mplot3d中沒有名為外部的模塊

Question

我正在嘗試使用帶有matplotlib的mpl_toolkits.mplot3d.Axes3D可視化3d圖

我正在將Matplot版本'2.1.0'和scikit-learn verison 0.19.0使用python 3。 當我運行代碼時，它會產生以下錯誤，

from matplotlib.externals import six
ImportError: No module named 'matplotlib.externals'

我試圖通過刪除現有的matplotlib並再次安裝來解決此問題，但沒有任何運氣。

我正在嘗試運行此代碼

import numpy as np
import mglearn
import matplotlib.pyplot as plt
from sklearn.datasets import make_blobs
from mpl_toolkits.mplot3d import Axes3D, axes3d


X, y = make_blobs(centers=4, random_state=8)
y = y % 2

X_new = np.hstack([X, X[:, 1:] ** 2])

figure = plt.figure()
ax = Axes3D(figure, elev=-152, azim=-26)
# plot first all the points with y == 0, then all with y == 1
mask = y == 0
ax.scatter(X_new[mask, 0], X_new[mask, 1], X_new[mask, 2], c='b', cmap=mglearn.cm2, s=60)
ax.scatter(X_new[mask, 0], X_new[mask, 1], X_new[mask, 2], c='r', marker='^', cmap=mglearn.cm2, s=60)
ax.set_xlabel("feature0")
ax.set_ylabel("feature1")
ax.set_zlabel("feature1 ** 2")

plt.show()

Answer 1

執行：

sudo apt-get remove python3-matplotlib

根據您的錯誤日志，這將刪除/usr/lib/python3/dist-packages/ 。
