Python壞了，AttributeError：'模塊'對象沒有屬性'python_version'

我在Windows上運行2.7。直到昨天，當我嘗試使用multiprocessing庫來運行一些作業，出現一堆內存錯誤，並且所有內容都崩潰時，我一直沒有問題。Python壞了，AttributeError：'模塊'對象沒有屬性'python_version'

這是當我嘗試運行pip會發生什麼：

Traceback (most recent call last): 
    File "C:\Python27\lib\runpy.py", line 162, in _run_module_as_ma 
    "__main__", fname, loader, pkg_name)

ne 1320, in MarkerEvaluation 
    'python_full_version': platform.python_version, 
AttributeError: 'module' object has no attribute 'python_version'

我得到同樣的事情，當我嘗試import pandas從Python外殼。奇怪的是，當替代進口熊貓我嘗試運行import pandas as pd，我得到這個錯誤：

In [3]: import pandas as pd 
cannot import name hashtable 
------------------------------------------ 
ImportError 
<ipython-input-3-af55e7023913> in <module> 
----> 1 import pandas as pd 

C:\Python27\lib\site-packages\pandas\__ini 
     5 
     6 try: 
----> 7  from . import hashtable, tslib 
     8 except Exception: # pragma: no co 
     9  import sys 

ImportError: cannot import name hashtable

任何想法，我怎麼能解決這個問題，而不完全重新安裝Python和我所有的圖書館？
