parafac function error

[yfji]

Hi. I test the CP decomposition and I met a mistake returned by parafac: last, first, vertical, horizontal = parafac(W, rank=rank, init='random') ValueError: not enough values to unpack (expected 4, got 2) I checked the returns of parafac, which should be a tensor. The version of tensorly is 0.4.5
