Pandas: AttributeError: 'module' object has no attribute 'version'

Question

当我尝试将 pandas 导入 Python 时，出现此错误：

>>> import pandas
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/robertdefilippi/miniconda2/lib/python2.7/site-packages/pandas/__init__.py", line 44, in <module>
    from pandas.core.api import *
  File "/Users/robertdefilippi/miniconda2/lib/python2.7/site-packages/pandas/core/api.py", line 9, in <module>
    from pandas.core.groupby import Grouper
  File "/Users/robertdefilippi/miniconda2/lib/python2.7/site-packages/pandas/core/groupby.py", line 17, in <module>
    from pandas.core.frame import DataFrame
  File "/Users/robertdefilippi/miniconda2/lib/python2.7/site-packages/pandas/core/frame.py", line 41, in <module>
    from pandas.core.series import Series
  File "/Users/robertdefilippi/miniconda2/lib/python2.7/site-packages/pandas/core/series.py", line 2909, in <module>
    import pandas.tools.plotting as _gfx
  File "/Users/robertdefilippi/miniconda2/lib/python2.7/site-packages/pandas/tools/plotting.py", line 135, in <module>
    if _mpl_ge_1_5_0():
  File "/Users/robertdefilippi/miniconda2/lib/python2.7/site-packages/pandas/tools/plotting.py", line 130, in _mpl_ge_1_5_0
    return (matplotlib.__version__  >= LooseVersion('1.5')
AttributeError: 'module' object has no attribute '__version__'

但是当我检查是否安装了 pandas 时：

me$ conda install pandas
Fetching package metadata: ....
Solving package specifications: .....................
# All requested packages already installed.
# packages in environment at /Users/me/miniconda2:
#
pandas                    0.17.1              np110py27_0

所以我不知道哪里出了问题？我的 pandas 怎么了？

编辑

$ pip list |grep matplotlib
$ conda list matplotlib
# packages in environment at /Users/me/miniconda2:
#
matplotlib                1.5.0               np110py27_0

由于某种原因没有输出到 pip list |grep matplotlib

我想看看可执行文件 ipython 和 python 是否有不同的路径。所以我运行这个：

$ python
>>> import sys
>>> print sys.executable 
/Users/me/miniconda2/bin/python

但是在 IPython 中，我得到了这个：

$ ipython notebook
>>> import sys
>>> print sys.executable
/usr/local/opt/python/bin/python2.7

会不会是这个问题？

Answer 1

从当前工作目录中删除（或重命名）文件 matplotlib.py。它隐藏了同名的真实图书馆。

Answer 2

我有一个简单的解决办法，删除你的项目字典中的__init__.pyc和__init__.py文件。因为我也遇到了这个问题，我已经用这个方法完美解决了

Pandas: AttributeError: 'module' object has no attribute '__version__'

Pandas: AttributeError: 'module' object has no attribute '__version__'

python

import
