larray.Array.to_hdf¶
-
Array.
to_hdf
(self, filepath, key)[source]¶ Writes array to a HDF file.
A HDF file can contain multiple arrays. The ‘key’ parameter is a unique identifier for the array.
- Parameters
- filepathstr
Path where the hdf file has to be written.
- keystr or Group
Key (path) of the array within the HDF file (see Notes below).
Notes
Objects stored in a HDF file can be grouped together in HDF groups. If an object ‘my_obj’ is stored in a HDF group ‘my_group’, the key associated with this object is then ‘my_group/my_obj’. Be aware that a HDF group can have subgroups.
Examples
>>> a = ndtest((2, 3))
Save an array
>>> a.to_hdf('test.h5', 'a')
Save an array in a specific HDF group
>>> a.to_hdf('test.h5', 'arrays/a')
