norse.torch.utils.tensorboard.hook_spike_activity_sum(key: str, writer: SummaryWriter) Callable[[Module, Tuple[Tensor, Any], Any], None][source]#

Generates a hook that can be applied to stateful torch Modules. The hook plots the summed neuron activity as a line, assuming that the module output is a tuple of (spikes, state). That is, this will not work on modules that only returns a single tensor as output (i. e. have no state).

Read more about hooks in PyTorch Modules in the Module documentation.

key (str): The name of the module as referred to in Tensorboard writer (SummaryWriter): The Tensorboard Writer to log to.


A hook that will plot the mean neuron spike activity when registered to a Torch module.
