vine copulas about copulas

[DILIU899]

Maybe you can try:
copula = copulas.multivariate.vine.VineCopula('regular')
copula.fit(data)

Hi @noonsad, I think @DILIU899 is correct.

I also referenced the API docs. When you instantiate a VineCopula, the first argument should be the vine type -- which a string of either 'regular', 'center' or 'direct'.

I'm closing the issue off since this seems to solve the error. Please feel free to reply if you continue to notice any crashes and we can reopen to investigate.

@DILIU899 and @npatki thanks for the response guys! you're right.
I have tried this and it works:

from copulas.multivariate import VineCopula
copula = VineCopula('center') #center is the type, 'regular' and 'direct' are also available.
copula.fit(data)
