Hello, I’m working with PyMC and encountering an issue when defining a multivariate normal distribution. My objective is to fit a 2D Gaussian to data (x1 and x2) of stars, incorporating observational errors (error_x1 and error_x2). However, when I define my model and attempt to run the sampler, I e…

Try to call .eval on the cov and mu variables to see if they have the shape you expected them to have
