进口熊猫不在码头工作；在pythonshell中工作

我在把熊猫输入我的iPython笔记本时遇到了一些问题。但是，当我将pandas导入到pythonshell中时，它可以工作

让我们看看我的代码：

from __future__ import division
import pandas as pd
import numpy as np

churn_df = pd.read_csv('churn_data.csv')
col_names = churn_df.columns.tolist()

print "Columns names:"
print col_names

to_show = col_names[:6] + col_names[-6:]

print "/nSample data:"
churn_df[to_show.head(6)]

我得到了这个错误：

我对自己做错的事有点不知所措。我想这可能是因为我安装了多个版本的python，但我不太清楚问题出在哪里

感谢您在笔记本中键入：

In [1]: %ls matplotlib.py

---

如果您看到列出了一个文件

matplotlib.py

，请将其删除或重命名（使用命令行或文件浏览器之类的工具），然后再次尝试导入。

Idle know all path，但您的系统不知道！尝试从源代码安装panda。Idle与python终端不同。（一种观点：

pip

不等于

apt-get

get很多差异）
