python读H5文件报错

[qq_39614744]

我在CONSOLE里写：

In [10]: h5=pd.HDFStore('./1.h5')
...: futures_data=h5['futures_data']
...: optoins_data=h5['options_data']
...: h5.close()
...:
Traceback (most recent call last):

File "<ipython-input-10-9456390f7543>", line 2, in <module>
futures_data=h5['futures_data']

File "C:\Anaconda2\lib\site-packages\pandas\io\pytables.py", line 413, in __getitem__
return self.get(key)

File "C:\Anaconda2\lib\site-packages\pandas\io\pytables.py", line 622, in get
raise KeyError('No object named %s in the file' % key)

KeyError: 'No object named futures_data in the file'

这错误 是H5文件没读出来吗？
