Parameters path_or_bufstr, path object, pandas.hdfstore Let us examine the data set as a dataset object. The documentation can be found here. We first load the numpy and h5py modules. >>> import h5py >>> f = h5py.file('mytestfile.hdf5', 'r') the file object is your starting point. Remember h5py.file acts like a python dictionary, thus we can check the keys, >>> list(f.keys()) ['mydataset'] The file object is your starting point.h5py.file acts like a python dictionary, thus we can check the keys, based on our observation, there is one data set, mydataset in the file. 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. To see what data is in this file,. Web the very first thing you’ll need to do is to open the file for reading:
>>> hf = h5py.file ('/path/to/file', 'r') >>> data = hf.get ('dataset_name').value # `data` is now an ndarray. You can also slice the dataset, which produces an actual ndarray with the requested data: My code import h5py import numpy as np f1 = h5py.file(file_name,'r+') this works and the file is read. >>> import numpy as np >>> import h5py >>> f = h5py.file('file.h5', 'r') >>> list(f.keys()) [u'data'] >>> dset = f[u'data'] >>> dset.shape (64, 64, 64) >>> dset.dtype dtype(('<f8', (3,))) 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. But how can i access data inside the file object f1? Parameters path_or_bufstr, path object, pandas.hdfstore Web mario, you can read the hdf5 file with any of the python modules mentioned above (pandas, pytables, or h5py). I can read the hdf5 file using h5py, but i cannot figure out how to access data within the file. Web 6 answers sorted by: 34 the easiest thing is to use the.value attribute of the hdf5 dataset.
