Update ref by assigning value to it.
tf.assign(
ref, value, validate_shape=None, use_locking=None, name=None
)
This operation outputs a Tensor that holds the new value of ref after
the value has been assigned. This makes it easier to chain operations that
need to use the reset value.
Args |
|---|
ref
|
A mutable Tensor. Should be from a Variable node. May be
uninitialized.
|
value
|
A Tensor. Must have the same shape and dtype as ref. The value to
be assigned to the variable.
|
validate_shape
|
An optional bool. Defaults to True. If true, the
operation will validate that the shape of 'value' matches the shape of the
Tensor being assigned to. If false, 'ref' will take on the shape of
'value'.
|
use_locking
|
An optional bool. Defaults to True. If True, the assignment
will be protected by a lock; otherwise the behavior is undefined, but may
exhibit less contention.
|
name
|
A name for the operation (optional).
|
Returns |
|---|
A Tensor that will hold the new value of ref after
the assignment has completed.
