H5py

Released: Apr 8,

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.

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.

Jun 22, Best of all, the files you create are h5py a widely-used standard binary format, h5py, which you can exchange with other peopleh5py, including those who use programs like IDL and MATLAB. This version.

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.

Released: Feb 8, View statistics for this project via Libraries. The library is provides a high-level interface to the REST specification that is generally easier to use than invoking http calls directly. The package is based on the popular h5py package and aims to be source compatible with the h5py high level interface. By default the examples look for a local instance of HSDS. When using AWS Lambda some additional environment variables need to be set:. For direct mode, some additional environment variables are needed to be defined:. Use hstouch command to create the folder before running the test, e.
