Hello, I am using: - TFP Version 0.16.0 - TF Version 2.8.1 I am training a [simple model on a density estimation task](https://github.com/MArpogaus/TensorFlow-Probability-Bernstein-Polynomial-Bijector/blob/ca828edd0c53ee96ba457d2f32b00399818e35a0/cml/old_faithful.py). When using a [`DistributionLambda`](https://www.tensorflow.org/probability/api_docs/python/tfp/layers/DistributionLambda) in conjunction with...
