dataset_take_while {tfdatasets}

A transformation that stops dataset iteration based on a predicate.

Description

A transformation that stops dataset iteration based on a predicate.

Usage

dataset_take_while(dataset, predicate, name = NULL)

Arguments

dataset

A TF dataset

predicate

A function that maps a nested structure of tensors (having shapes and types defined by self$output_shapes and self$output_types) to a scalar tf.bool tensor.

name

(Optional.) A name for the tf.data operation.

Details

Example usage:

 range_dataset(from = 0, to = 10) %>%
   dataset_take_while( ~ .x < 5) %>%
   as_array_iterator() %>%
   iterate(simplify = FALSE) %>% str()
 #> List of 5
 #> $ : num 0
 #> $ : num 1
 #> $ : num 2
 #> $ : num 3
 #> $ : num 4

Value

A TF Dataset
