python - 导入错误 : cannot import name '_ccallback_c'

Question

最初我遇到这个错误(没有找到模块名称 scipy)所以我安装了一个 Scipy wheel 文件。现在我不再遇到同样的错误，但我得到了 cannot import name "_ccallback_c"。

错误似乎是在第四行代码处触发的。我做了我的研究，看到其他人建议尝试像 Anaconda 这样的环境。我已经看到它在闲置时工作，并且该解决方案对我来说并不理想。

回溯:

Traceback (most recent call last):

    from . import _ccallback_c
ImportError: cannot import name '_ccallback_c'

和代码:

import pandas as pd
import quandl, math
import numpy as np
from sklearn import preprocessing, cross_validation, svm 
from sklearn.linear_model import LinearRegression

Answer 1

我在 USING Anaconda 上遇到了同样的错误，所以我不确定使用它是否会有任何不同。我通过卸载 scipy 并使用 pip 重新安装它来解决它:

pip uninstall scipy 

您会收到此消息:

Uninstalling scipy-1.1.0: Would remove: c:\users\thesh\appdata\local\programs\python\python36-32\lib\site-packages\scipy-1.1.0.dist-info* c:\users\thesh\appdata\local\programs\python\python36-32\lib\site-packages\scipy* Proceed (y/n)?

按 y，pip 完成后，输入:

pip install scipy
