Hi there, I am new to Pyro so I hope this question makes sense. I created the following model:

```
def model():
a1 = pyro.sample("a1", pyro.distributions.Normal(0.0, 1.0))
a2 = pyro.sample("a2", pyro.distributions.Normal(0.0, 1.0))
cond_v = torch.where((a1 + a2) > 5, 1., 0.)
cond = pyro.sample("cond", pyro.distributions.Bernoulli(cond_v))
return cond
```

For this model, I created a condition which is unlikely to be true (given the samples from the normal distributions). When I run inference on this model and condition on â€ścondâ€ť to be 1.0, then NUTS simply â€śignoresâ€ť the conditioning and samples some values for a1 and a2 so that â€ścondâ€ť will be 0.0. If I change torch.where((a1 + a2) > 5, 1., 0.) to torch.where((a1 + a2) > 4, 1., 0.), meaning it becomes more likely, it works fine. Maybe I am not understanding NUTS entirely, but could someone explain to me why this happens?
