Manual indexing

[smorad]

Is there a way to slice and get a portion of the replay buffer starting at a specific index? Ideally, something like

rb = ReplayBuffer(...)
rb[100:200]

There is rb.get_all_transitions['obs'][100:200] but this requires materialising the entire replay buffer to get just a sample. Is this efficient?

Thank you for your feedback.

There is a private but almost stable method ReplayBuffer._encode_sample(indices)

cpprb/cpprb/PyReplayBuffer.pyx

Line 1321 in 3b791b5

def _encode_sample(self,idx):

You can pass list of indices.
