@tomcraven thank you for providing this example. It uncovered an important bug: Tangram is not properly handling linear models that fail to converge.
At the end of training, we compare each of the models using the model comparison metric and we assumed they all had a finite root mean squared error. This was not the case here because two of the models in the grid failed to converge during training.
I'm working on a fix now and I'll let you know when it is ready.
@tomcraven @nitsky made a change that filters out the models that have NaN comparison metric values. https://github.com/tangramxyz/tangram/commit/af0e48cb0f166ea43e5721c8d82a70c0dd43ffd7. We are working on a new release now and I'll let you know when it's available.
amazing! thank you @isabella & @nitsky
@tomcraven this should be fixed in v0.6.0. Please re-open this issue if you are still having trouble.

i've attached my test data that causes this issue, apologies it's so large (edit: maybe it's not that bad :smile: ) it was the smallest reproducible test set i could come up with
let me know if there's anything else i can provide!
