RuntimeDevice
[source]¶ Bases:
brian2.devices.device.Device
The default device used in Brian, state variables are stored as numpy arrays in memory.
Attributes
arrays
Mapping from Variable
objects to numpy arrays (orDynamicArray
objects).Methods
add_array
(var)Add an array to this device. fill_with_array
(var, arr)Fill an array with the values given in another array. get_array_name
(var[, access_data])Return a globally unique name for var
.get_random_state
()Return a (pickable) representation of the current random number generator state. get_value
(var[, access_data])init_with_arange
(var, start, dtype)Initialize an array with an integer range. init_with_zeros
(var, dtype)Initialize an array with zeros. resize
(var, new_size)Resize a DynamicArrayVariable
.resize_along_first
(var, new_size)seed
([seed])Set the seed for the random number generator. set_random_state

arrays
¶ Mapping from
Variable
objects to numpy arrays (orDynamicArray
objects). Arrays in this dictionary will disappear as soon as the last reference to theVariable
object used as a key is gone
-
get_random_state
()[source]¶ Return a (pickable) representation of the current random number generator state. Providing the returned object (e.g. a dict) to
Device.set_random_state
should restore the random number generator state.
-
set_random_state
(state)[source]¶ Reset the random number generator state to a previously stored state (see
Device.get_random_state
).
