tf.contrib.distributions.InverseGamma.__init__(alpha, beta, validate_args=False, allow_nan_stats=True, name='InverseGamma')
Construct InverseGamma distributions with parameters alpha and beta.
The parameters alpha and beta must be shaped in a way that supports broadcasting (e.g. alpha + beta is a valid operation).
Args:
alpha: Floating point tensor, the shape params of the distribution(s). alpha must contain only positive values.
beta: Floating point tensor, the scale params of the distribut
