AttributeError: module 'numpy' has no attribute 'product'

Problem

Tonic is using a deprecated reference for product, now used as prod, in plot_event_grid method in utils.py

Solution

In utils.py replace line:

        transform = transforms.ToFrame(
            sensor_size=sensor_size, n_time_bins=np.product(axis_array)
        )

with line:

    # Use np.prod() instead of deprecated np.product()
    transform = tonic.transforms.ToFrame(
        sensor_size=sensor_size, n_time_bins=np.prod(axis_array)
    )
