Thanks @ayn2! I presume this error doesn't happen when we run SygnetModel(..., mixed_activation=False)?

[ayn2]

Nope, happens still

Not using mixed activation function -- generated data may not conform to real data if it contains categorical columns.

[ayn2]

It does complete the training though, including completing >1 epochs if needed.

[tsrobinson]

No problem, I'll figure it out! Thanks for checking

[tsrobinson]

Hmmm, I'm not able to replicate this one using the code above, and the following imports:

import numpy as np
import pandas as pd
from numpy.random import default_rng
from sygnet import SygnetModel

It may be we've just overlapped on versions. If you're calling this internally, I'm happy to check again with the full dependency list etc. (just reopen this issue)
