Configuring h5py¶
Library configuration¶
A few library options are available to change the behavior of the library.
You can get a reference to the global library configuration object via the
function h5py.get_config(). This object supports the following
attributes:
- complex_names
Set to a 2-tuple of strings (real, imag) to control how complex numbers are saved. The default is (‘r’,’i’).
- bool_names
Booleans are saved as HDF5 enums. Set this to a 2-tuple of strings (false, true) to control the names used in the enum. The default is (“FALSE”, “TRUE”).
- track_order
Whether to track dataset/group/attribute creation order. If container creation order is tracked, its links and attributes are iterated in ascending creation order (consistent with
dictin Python 3.7+); otherwise in ascending alphanumeric order. Global configuration value can be overridden for particular container by specifyingtrack_orderargument toh5py.File,h5py.Group.create_group(),h5py.Group.create_dataset(). The default isFalse.
