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.
