Converts a rotation matrix representation to a quaternion.

This function is not smooth everywhere.

In the following, A1 to An are optional batch dimensions.

rotation_matrix A tensor of shape [A1, ..., An, 3, 3], where the last two dimensions represent a rotation matrix.
name A name for this op that defaults to "quaternion_from_rotation_matrix".

A tensor of shape [A1, ..., An, 4], where the last dimension represents a normalized quaternion.

ValueError If the shape of rotation_matrix is not supported.
