pescador.maps.buffer_stream

pescador.maps.buffer_stream(stream, buffer_size, partial=False, axis=None)

Buffer “data” from an stream into one data object.

Parameters:
stream : stream

The stream to buffer

buffer_size : int > 0

The number of examples to retain per batch.

partial : bool, default=False

If True, yield a final partial batch on under-run.

axis : int or None

If None (default), concatenate data along a new 0th axis. Otherwise, concatenation is performed along the specified axis.

This is primarily useful when combining data that already has a dimension for buffer index, e.g., when buffering buffers.

Yields:
batch

A batch of size at most buffer_size

Raises:
DataError

If the stream contains items that are not data-like.
