Long term things to think about

[michaeldeistler]

• [ ] should our tests be bimodal?
• [x] slow tests for all pyro samplers (hmc requires gradients...)
• [ ] should we start thinking about a v1.0.0 release?
• [x] progress bar for rejection sampling seems to be missing?
• [ ] what to do when samples are outside of the bins?
• [ ] SNLE and SNRE should not allow handle_invalid_x.
• [x] In the learning summstats tutorial, does it really make sense to have a ReLU at the end (after all layers)?
• [x] FAQ dill bug
