random access logic

[etienne87]

Hi, thanks for this great dataset! I would like to code a random access function getitem that, given index i, num_skip s, returns the necessary data to train. Can i assume that:

• input is image_png[i], image_png[i+s], event_npz[i], timestamps[i], timestamps[i+s]
• output is, given chosen intermediate time tau in [i, i+s]: image_png[tau].

When i try this i sometimes get events that begin before timestamps[i]

Ah, i think i understand reading at your code. In fact there is no per se a strict correspondance between file index and events, because you concatenate all event files and then perform a linear search using the timestamps as input. Therefore this question boils down to using a np.searchsorted inside the events.
