Hello, it tooks me a whlie to understand this: ``` my_pdf = tfp.layers.MixtureNormal(3, 1)(np.array([1/3, 0/3, 2/3, 4, # mean1 5, # std1 6, # mean2 7, # std2 8, #...

Mixture model (Zero-inflated) gives nan log-probablity at 0

6

To reproduce the result: ``` import tensorflow_probability as tfp tfd = tfp.distributions # Zero inflated log-normal ziln = tfd.Mixture( cat=tfd.Categorical(probs=[0.9, 0.1]), components=[ tfd.Deterministic(loc=0), tfd.LogNormal(loc=6, scale=1), ]) print(ziln.log_prob(0)) # Expected output:...
