Hi, I am currently studying the usage of GMMs in pymc. I wanted to get the log likelihood of a GMM model and had problems to retrieve it by how I implemented it. Lets look into this very simple example, and this will work: ### some data: rng = np.random.default_rng(123) N = 1000 W = np.array([0…

In the meantime you can get around by not setting initval in the distribution, and instead define in initvals when calling pm.sample

Understanding implementation of initial values in the usage with GMMs

When do you get the error? Is it when computing log_likelihood?
