Custom validation set

Hi, I find this package very useful for EDA, however current it does not support using custom validation set in fit(). In XGBoost / Lightgbm, there is a parameter eval_set...

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:...
