Lkjcorr returning error

8

Anyway, here is a quick fix for the time being:

import pymc as pm
from pymc.distributions.transforms import Interval


class MultivariateIntervalTransform(Interval):
    name = "interval"
        
    def log_jac_det(self, *args):
        return super().log_jac_det(*args).sum(-1)
    
tr = MultivariateIntervalTransform(-1.0, 1.0)

with pm.Model() as m:
    x = pm.LKJCorr("x", n=3, eta=1, transform=tr)
m.logp()  # Should not fail
