Global Functions¶
def prepare_model()
Prepare a model by checking its validity and extracting information about variables and parameters.
Parameters:
model | string or instance of a class derived from ``pygenn.genn_wrapper.CurrentSourceModels.Custom`` @param param_space dict with model parameters @param var_space dict with model variables @param pre_var_space optional dict with (weight update) model presynaptic variables |
post_var_space | optional dict with (weight update) model postsynaptic variables |
model_family |
``pygenn.genn_wrapper.CurrentSourceModels`` @return tuple consisting of (model instance, model type, model parameter names, model parameters, list of variable names, dict mapping names of variables to instances of class Variable) |
def prepare_snippet()
Prepare a snippet by checking its validity and extracting information about parameters.
Parameters:
snippet | string or instance of a class derived from ``pygenn.genn_wrapper.InitSparseConnectivitySnippet.Custom`` @param param_space dict with model parameters @param snippet_family ``pygenn.genn_wrapper.InitVarSnippet`` or ``pygenn.genn_wrapper.InitSparseConnectivitySnippet`` @return tuple consisting of (snippet instance, snippet type, snippet parameter names, snippet parameters) |
def is_model_valid()
Check whether the model is valid, i.e is native or derived from model_family.Custom.
Raises ValueError if model is not valid (i.e. is not custom and is not natively available)
Parameters:
model | string or instance of model_family.Custom |
model_family | model family (NeuronModels, WeightUpdateModels or PostsynapticModels) to which model should belong to |
Returns:
instance of the model and its type as string
def param_space_to_vals()
Convert a param_space dict to ParamValues.
Parameters:
model | instance of the model |
param_space | dict with parameters |
Returns:
native model’s ParamValues
def param_space_to_val_vec()
Convert a param_space dict to a std::vector<double>
Parameters:
model | instance of the model |
param_space | dict with parameters |
Returns:
native vector of parameters
def var_space_to_vals()
Convert a var_space dict to VarValues.
Parameters:
model | instance of the model |
var_space | dict with Variables |
Returns:
native model’s VarValues
def pre_var_space_to_vals()
Convert a var_space dict to PreVarValues.
Parameters:
model | instance of the weight update model |
var_space | dict with Variables |
Returns:
native model’s VarValues
def post_var_space_to_vals()
Convert a var_space dict to PostVarValues.
Parameters:
model | instance of the weight update model |
var_space | dict with Variables |
Returns:
native model’s VarValues
