Details
- It's possible to serialize the entire state of an
Instr object to file, including to an HDF5 file.
- Retrieving the full
Instr object from this state is slow for as-yet-undetermined reasons.
- Sometimes only part of the state is needed, and a modification to
load_hdf5 would be possible to enable specifying what part of the file to load more-quickly.
Ideas
- Profile de-serialization to work out what part(s) are possibly worth improving
- Add an in-file
path keyword argument to load_hdf5 to select out just, e.g., the instrument parameters.
Temporary workaround
import h5py
from mccode_antlr.io.hdf5 import HDF5IO
with h5py.File(filename, 'r', driver='core', backing_store=False) as file:
return HDF5IO.load(file['parameters'])
