Missing Inverse Wishart - redefine Wishart?

This seems like an odd distribution to be missing, especially given that it is the standard conjugate prior for the covariance matrix of multivariate normals. Technically, it can be instantiated...

I would like to transform a mixture of distributions into another distribution and then apply the learned transformation to the individual components for a specific engineering application. While I am...

Hi all, I'm trying to compute a posterior predictive distribution over samples from a posterior distribution ([Colab here](https://colab.research.google.com/drive/1dNzAPXhkyKcap_ipEdNEmPFObVVrDJov?usp=sharing)). TFP 0.25 with JAX backend. My (mre and therefore contrived) model specification...

``` File ".../venvserver/lib/python3.12/site-packages/tensorflow_probability/python/internal/backend/jax/ops.py", line 681, in jax.interpreters.xla.pytype_aval_mappings[onp.ndarray]) ... AttributeError: jax.interpreters.xla.pytype_aval_mappings was deprecated in JAX v0.5.0 and removed in JAX v0.7.0. jax.core.pytype_aval_mappings can be used as a replacement in most cases....

The TensorFlow probability implementation of softplus leaks memory, and appears to no longer be needed. That is, I think the standard `tf.nn.softplus` implementation can be used now, as numerical stability...
