Looking for statsmodels.tsa.stattools.grangercausalitytests

Hey people,

I am looking to run some Granger causality test on some datasets in one of my notebooks and cannot access the grangercausalitytest() from the statsmodel package. I get the following error:
SecurityViolation: 0002 Security Violation(s): Accessing sm.grangercausalitytests raised an AttributeError. No attributes with a similar name were found.

I am aware that some functions of this package are blocked, but can the function for Granger test be whitelisted? Whom should I contact for this? I really need it for my thesis.

Thanks for the help.
