tf.range(start, limit=None, delta=1, dtype=None, name='range')
See the guide: Constants, Sequences, and Random Values > Sequences
Creates a sequence of numbers.
Creates a sequence of numbers that begins at start
and extends by increments of delta
up to but not including limit
.
The dtype of the resulting tensor is inferred from the inputs unless it is provided explicitly.
Like the Python builtin range
, start
defaults to 0, so that range(n) = range(0, n)
.
For example:
# 'start' is 3 # 'limit' is 18 # 'delta' is 3 tf.range(start, limit, delta) ==> [3, 6, 9, 12, 15] # 'start' is 3 # 'limit' is 1 # 'delta' is -0.5 tf.range(start, limit, delta) ==> [3, 2.5, 2, 1.5] # 'limit' is 5 tf.range(limit) ==> [0, 1, 2, 3, 4]
start
: A 0-D Tensor
(scalar). Acts as first entry in the range if limit
is not None; otherwise, acts as range limit and first entry defaults to 0.limit
: A 0-D Tensor
(scalar). Upper limit of sequence, exclusive. If None, defaults to the value of start
while the first entry of the range defaults to 0.delta
: A 0-D Tensor
(scalar). Number that increments start
. Defaults to 1.dtype
: The type of the elements of the resulting tensor.name
: A name for the operation. Defaults to "range".An 1-D Tensor
of type dtype
.
