• **kwargs: 'graph': tf.Graph in which to perform the regex query.This is required when using regex. 'positive_filter': an elem if selected only if positive_filter(elem) is True. This is optional. 'restrict_ops_regex': a regular expression is ignored if it doesn't start with the substring "(?#ops)".

• ValueError: if one of the keyword arguments is unexpected or if a regular expression is used without passing a graph as a keyword argument.
