load_parameters

load_parameters(filename, global_only=True, verbose=False, net_id=0)

Loads the global parameters of a network (flag population for neurons, projection for synapses) from a JSON file.

It returns a dictionary of additional parameters not related to populations or projections (keyword network in the JSON file).

It is advised to generate the JSON file first with save_parameters() and later edit it manually.

A strong restriction is that population/projection names cannot change between saving and loading. By default, they take names such as pop0 or proj2, we advise setting explicitly a name in their constructor for readability.

If you add a parameter name to the JSON file but it does not exist in te neuron/synapse, it will be silently skipped. Enable verbose=True to see which parameters are effectively changed.

If you set global_only to True, you will be able to set values for non-global parameters (e.g. synapse-specific), but a single value will be loaded for all. The JSON file cannot contain arrays.

If you want to save/load the value of variables after a simulation, please refer to save() or load().

Parameters

Name	Type	Description	Default
filename	str	path to the JSON file.	required
global_only	bool	True if only global parameters (flags population and projection) should be loaded, the other values are ignored. (default: True)	True
verbose	bool	True if the old and new values of the parameters should be printed (default: False).	False
