error in behavioral_pls while reproducing the example

[nSpotorno]

Thank you very much for this repository!
I was trying to use behavioral_pls but I am encountering a problem while reproducing the example "An exercise in calisthenics"
running

from pyls.examples import load_dataset
data = load_dataset('linnerud')

results = behavioral_pls(**data)

I get an error related to matrix dimensions mismatch in matmul:

ValueError: matmul: Input operand 1 has a mismatch in its core dimension 0, with gufunc signature (n?,k),(k,m?)->(n?,m?) (size 1 is different from 3)

the same happen if I use my own data. Any idea from where the error is coming from and how could I fix it?

during the installation of pypls I got a warning that "Package 'pyls.tests.data' is absent from the packages configuration" but the installation proceeded.
Many thanks in advance!

I'm also having the same issue as well after re-installing pypls.
