Released: Oct 9, View statistics for this project via Libraries. The h5py package provides both a high- and low-level interface to the HDF5 library from Python. A strong emphasis on automatic conversion between Python Numpy datatypes and data structures and their HDF5 equivalents vastly simplifies the process of reading and writing data from Python. Wheels are provided for several popular platforms, with an included copy of the HDF5 library usually the latest version when h5py is released. You can also build h5py from source with any HDF5 stable release from version 1. Odd-numbered minor versions of HDF5 e.

H5py

The kinds of cosmological simulations that I run generate huge amounts of data, and to analyse them I need to be able access the exact data that I want quickly and painlessly. HDF5 is one answer. It provides parallel IO, and carries out a bunch of low level optimisations under the hood to make queries faster and storage requirements smaller. Getting h5py is relatively painless in comparison, just use your favourite package manager. We first load the numpy and h5py modules. The first step to creating a HDF5 file is to initialise it. It uses a very similar syntax to initialising a typical text file in numpy. The first argument provides the filename and location, the second the mode. This creates a file object, hf , which has a bunch of associated methods. Just provide a name for the dataset, and the numpy array. To open and read data we use the same File method in read mode, r.

The h5py package is a Pythonic interface to the HDF5 binary data format. It lets you store huge amounts of numerical data, and easily manipulate that data from NumPy. For example, you can slice into multi-terabyte datasets stored on disk, as if they were real NumPy arrays. Thousands of datasets can be stored in a single file, categorized and tagged however you want. For example, you can iterate over datasets in a file, or check out the.

Groups are the basic container mechanism in a HDF5 file, allowing hierarchical organisation of the data.
