Hi,
I encountered a similar issue like #1824, where the target value (i.e.
y) was np.float32, then the computedy_scalewas np.float32 as well, which caused json serialization to fail.In my scenario, the extra regressors were np.float32, so
muandstdare also np.float32 and I'm unable to serialize the model (of course after callingmodel_to_dict).The solution is just to convert it to float, same as in 9e4e87a.
Thanks!
