更新了蟒蛇，导入 scipy 时"cannot import name 'moduleTNC'"错误消息

Question

我使用conda update anaconda更新了windows上的anaconda。现在我的ipython笔记本，它以开始

import numpy as np
from numpy.random import randn
import pandas as pd
from scipy import stats
import matplotlib as mpl
import matplotlib.pyplot as plt
import seaborn as sns
...

正在给我错误：

如果我删除了导致错误的行，那么我在导入seaborn等时会出现错误…

我做错了什么？我该怎么修？

Answer 1

我发现底层pyd文件被命名为moduletnc.pyd，而不是moduletnc.pyd。当我将最后三个字母大写时，问题就解决了。

Answer 2

以下解决方案适用于windows 101.转到->C:\Python27\Lib\site packages\scipy\optimize2.将moduletnc文件重命名为moduletnc

Answer 3

尝试conda install -f scipy。这将迫使conda重新安装scipy。
