Returns the constant value of the given tensor, if efficiently calculable.
tf.get_static_value( tensor, partial=False )
This function attempts to partially evaluate the given tensor, and returns its value as a numpy ndarray if this succeeds.
Compatibility(V1): If constant_value(tensor)
returns a non-None
result, it will no longer be possible to feed a different value for tensor
. This allows the result of this function to influence the graph that is constructed, and permits static shape optimizations.
Args | |
---|---|
tensor | The Tensor to be evaluated. |
partial | If True, the returned numpy array is allowed to have partially evaluated values. Values that can't be evaluated will be None. |
Returns | |
---|---|
A numpy ndarray containing the constant value of the given tensor , or None if it cannot be calculated. |
Raises | |
---|---|
TypeError | if tensor is not an ops.Tensor. |
