tf.clip_by_value
Clips tensor values to a specified min and max.
tf.clip_by_value(
t, clip_value_min, clip_value_max, name=None
)
Given a tensor t
, this operation returns a tensor of the same type and shape as t
with its values clipped to clip_value_min
and clip_value_max
. Any values less than clip_value_min
are set to clip_value_min
. Any values greater than clip_value_max
are set to clip_value_max
.
Note: clip_value_min
needs to be smaller or equal to clip_value_max
for correct results.
For example:
A = tf.constant([[1, 20, 13], [3, 21, 13]])
B = tf.clip_by_value(A, clip_value_min=0, clip_value_max=3) # [[1, 3, 3],[3, 3, 3]]
C = tf.clip_by_value(A, clip_value_min=0., clip_value_max=3.) # throws `TypeError`
as input and clip_values are of different dtype
Args |
t | A Tensor or IndexedSlices . |
clip_value_min | A 0-D (scalar) Tensor , or a Tensor with the same shape as t . The minimum value to clip by. |
clip_value_max | A 0-D (scalar) Tensor , or a Tensor with the same shape as t . The maximum value to clip by. |
name | A name for the operation (optional). |
Returns |
A clipped Tensor or IndexedSlices . |
Raises |
ValueError | If the clip tensors would trigger array broadcasting that would make the returned tensor larger than the input. |
TypeError | If dtype of the input is int32 and dtype of the clip_value_min' or clip_value_maxis float32` |
