Hi I am new to pymc3. I want to do a simple matrix multiplication involving a tensor X and coefficients beta. If all in numpy, I could do beta * X, or np.matmul(X, beta), but I don’t know the equivalent in pymc3, but I have beta declared in pm alpha = pm.Normal('alpha', 0, sd=10) beta = pm.Normal(…

You can do: Y = alpha + pm.math.dot(X, beta)

You are displaying the symbolic shape. You can check the shape conditioned on the current input (under PyMC3 at least) by doing x_logit.tag.test_value.shape
