python怎么打开h5文件_用Python打开.h5文件
我正在尝试用Python读取h5文件。
该文件可以在this link中找到，名为“vstoxx_data_31032014.h5”。我试图运行的代码来自Yves Hilpisch的《Python for Finance》一书，内容如下：import pandas as pd
h5 = pd.HDFStore('path.../vstoxx_data_31032014.h5', 'r')
futures_data = h5['futures_data'] # VSTOXX futures data
options_data = h5['options_data'] # VSTOXX call option data
h5.close()
我得到以下错误：h5 = pd.HDFStore('path.../vstoxx_data_31032014.h5', 'r')
Traceback (most recent call last):
File "", line 1, in
h5 = pd.HDFStore('path.../vstoxx_data_31032014.h5', 'r')

self.open(mode=mode, **kwargs)

End of HDF5 error back trace

为了这个问题，我用我的工作目录替换了“path…/”。
有人知道这个错误可能来自哪里吗？
