chainer_chemistry.iterators.IndexIterator

class chainer_chemistry.iterators.IndexIterator(index_list, shuffle=True, num=0)

Index iterator

IndexIterator is used internally in BalancedSerialIterator, as each label’s index iterator

Args:

index_list (list): list of int which represents indices. shuffle (bool): shuffle flag. If True, indices specified by

index_list will be randomly shuffled.

num (int): number of indices to be extracted when ___next___ is

called.

__init__(index_list, shuffle=True, num=0)

Initialize self. See help(type(self)) for accurate signature.

Methods

__init__(index_list[, shuffle, num])	Initialize self.
finalize()	Finalizes the iterator and possibly releases the resources.
get_next_indices(num)	get next indices
next()	Python2 alternative of __next__.
serialize(serializer)	Serializes the internal state of the iterator.
update_current_index_list()
