Update 'ref' by subtracting 'value' from it.
tf.raw_ops.AssignSub(
ref, value, use_locking=False, name=None
)
This operation outputs "ref" after the update is done.
This makes it easier to chain operations that need to use the reset value.
Args |
ref
|
A mutable Tensor . Must be one of the following types: float32 , float64 , int32 , uint8 , int16 , int8 , complex64 , int64 , qint8 , quint8 , qint32 , bfloat16 , qint16 , quint16 , uint16 , complex128 , half , uint32 , uint64 .
Should be from a Variable node.
|
value
|
A Tensor . Must have the same type as ref .
The value to be subtracted to the variable.
|
use_locking
|
An optional bool . Defaults to False .
If True, the subtraction 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 mutable Tensor . Has the same type as ref .
