Map a function across a dataset.

Usage

dataset_map(dataset, map_func, num_parallel_calls = NULL)

Arguments

dataset	A dataset
map_func	A function mapping a nested structure of tensors (having shapes and types defined by output_shapes() and output_types() to another nested structure of tensors. It also supports purrr style lambda functions powered by rlang::as_function().
num_parallel_calls	(Optional) An integer, representing the number of elements to process in parallel If not specified, elements will be processed sequentially.

Value

A dataset
