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.
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.
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.
A numpy ndarray containing the constant value of the given
or None if it cannot be calculated.
TypeError: if tensor is not an ops.Tensor.
