肯定已安装，但未导入Python-2.7模块

Question

My pandas package is not getting imported. When I try to check if I have pandas using the command

python -c "import pandas"

It shows some strange error like

<module 'numpy' from 'numpy.pyc'>
'module' object has no attribute 'dtype'
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/usr/lib/python2.7/dist-packages/pandas/__init__.py", line 6, in   <module>
from . import hashtable, tslib, lib
File "numpy.pxd", line 157, in init pandas.hashtable    (pandas/hashtable.c:21706)
AttributeError: 'module' object has no attribute 'dtype'

Answer 1

You have a local file named numpy.py which is being imported instead of the globally installed NumPy project:

<module 'numpy' from 'numpy.pyc'>

Remove or rename that file and delete the associated numpy.pyc file next to it. Your local file has no name dtype , only the numpy package installed in your site-packages does, but it can't be loaded when your file is found first every time.
