Question

尝试运行实现Sci-Kit Learn的Python脚本时出错。这是我的代码：

import matplotlib.pyplot as plt
from sklearn import datasets
from sklearn import svm

digits = datasets.load_digits()
print (digits.data)
print (digits.target)
print (digits.images[0])

clf = svm.SVC(gamma=0.001, C=100)

x, y = digits.data[:-1], digits.target[:-1]

这是运行时遇到的错误＆＃34; python scidigits.py＆＃34; 在我的终端：

Traceback (most recent call last):
  File "Practice.py", line 6, in <module>
    from sklearn import svm
  File "/home/jdoe/.local/lib/python2.6/site-packages/sklearn/svm/__init__.py", line 13, in <module>

from scipy.optimize.linesearch import line_search_wolfe2, line_search_wolfe1
ImportError: cannot import name line_search_wolfe2

请问有人可以解释这个问题吗？

Answer 1

我想这是版本/弃用问题。

所以你应该更新你的scikit-learn包。

我如何解决这个问题＆＃34; line_search_wolfe2＆＃34;使用sci-kit学习时出错？
