Description:
 def get_dependencies(*distributions):
 """ Get underlying dependencies that are shared between distributions. If more than two distributions are provided, any pair-wise dependency between any two distributions are included, implying that an empty set is returned if and only if the distributions are i.i.d. Args: distributions: Distributions to check for dependencies. Returns: dependencies (List[Dist]):
 Distributions dependency shared at least between at least one pair from ``distributions``. Examples: [uniform(), Mul(uniform(), 0.5), Uniform(lower=1, upper=2)] [] [] [uniform(), Mul(uniform(), 0.5), Uniform(lower=1, upper=2)] """
