Some issues may happen when fitting data. There is a convergence problem using with the minimize function of scipy.
Here is an example with Gompertz distribution:
/home/xxx/.local/lib/python3.8/site-packages/relife/parametric.py:347: RuntimeWarning: invalid value encountered in sqrt
self.se = np.sqrt(np.diag(self.var))
Problem may be solved by improving the initialization "params0" and/or using another type of solver (by default L-BFGS).
