Hello,

I’m running a multivariate regression model and keep getting the following error:

```
ValueError: Error while computing log_prob at site 'obs':
The value argument must be within the support

linear.bias dist | 1
value | 1
log_prob |
obs dist 657878 |
value 657878 |
```

I’m copy/pasted from the tutorial, only changing the y variable to Poisson distributed. I’m not sure what the above means.
