Witryna@Anush I see. I would still go for the numerical integration, but with some kind of safeguards for division by zero and small values in the log function. For example, your function could be lambda x: 0 if f(x) < 1e-8 else f(x) * np.log(f(x) / g(x)), and using the np.inf upperbound. I just tested and it works.
