我正在尝试用Python读取一个h5文件。
该文件可在this link中找到,名为' vstoxx_data_31032014.h5'。我试图运行的代码来自Yves Hilpisch撰写的Python for Finance一书,如下所示:
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()
我收到以下错误:
h5 = pd.HDFStore('path.../vstoxx_data_31032014.h5', 'r')
Traceback (most recent call last):
File "<ipython-input-692-dc4e79ec8f8b>", line 1, in <module>
h5 = pd.HDFStore('path.../vstoxx_data_31032014.h5', 'r')

End of HDF5 error back trace

我将工作目录替换为&#39;路径... /&#39;为了这个问题的目的。
有谁知道这个错误可能来自哪里?
答案 0 :(得分:3)
要使用h5py
模块打开HDF5文件,您可以使用h5py.File(filename)
。可以找到文档here。
import h5py
filename = "vstoxx_data_31032014.h5"
h5 = h5py.File(filename,'r')
futures_data = h5['futures_data'] # VSTOXX futures data
options_data = h5['options_data'] # VSTOXX call option data
h5.close()
