obspy.signal.spectral_estimation.PPSD.load_npz¶

static PPSD.load_npz(filename, metadata=None, allow_pickle=False)[source]¶

Load previously computed PPSD results.

Load previously computed PPSD results from a compressed numpy binary in npz format, written with write_npz(). If more data are to be added and processed, metadata have to be specified again during loading because they are not stored in the npz format.

Parameters:	filename (str) Name of numpy .npz file with stored PPSD data metadata (`Inventory` or `xseed Parser` or str or dict) Response information of instrument. See notes in `PPSD.__init__()` for details. allow_pickle (bool) Allow the pickle protocol to be used when de-serializing saved PPSDs. This is only required for npz files written by ObsPy versions less than 1.2.0.
