H5ADMap.chunk_X(select: int | Sequence[int] | ndarray = 1000, replace: bool = True)

Return a chunk of the data matrix X with random or specified indices.

Parameters:

• select –

  Depending on the type:

  int

  A random chunk with select rows will be returned.

  sequence (e.g. a list, tuple or numpy array) of int

  A chunk with these indices will be returned.
