ProcessPoolExecutor uses the multiprocessing module, which allows it to side-step the Global Interpreter Lock but also means that only picklable objects can be executed and returned.. Here, \(p(X \ | \ \theta)\) is the likelihood, \(p(\theta)\) is the prior and \(p(X)\) is a normalizing constant also known as the evidence or marginal likelihood The computational issue is the difficulty of evaluating the integral in the denominator.
