about an exception
Hi, Jake @JakeColtman ,
After pull bartpy, and running it in the pycharm, I got following errors which prevents me to make forcasting (regression) with X is 50 by 10 and y is 50 by 1 The error is:

Can you tell me some hints? Thank you!
Hi, Thanks for trying it out and for raising an issue! As you might have guessed, Bartpy's not particularly battle tested at this point as I've mostly been working on the idea that other people wouldn't be trying to run it.
Would you mind posting the code that you're running so I can try debugging it?
