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.
