I got an error and could not figure out what is wrong. Can you guys help me what is wrong in the line I added with the comment ?
pystan_code3 = “”"
data {
int<lower=0> Nx;
int<lower=0> Ny;
matrix[Ny,Nx] A;
//vector[Ny] A[Nx];
vector[Ny] s;
}
transformed data {
}
parameters {
// simplex[Nx] m;
vector[Nx] m;
}
transformed parameters {
}
model {
vector[3] y;
y[1] = 0.5;
y[2] = 0.4;
y[3] = 0.1;
//y ~ normal( m , 0.01); // This line works
s ~ normal( A*m , 0.01); // This line causes compile errors
}
generated quantities {
}
"""
I think I can guess what hte error looks like but I’d rather not. Could you post the entire error message?

I tested with Nx = 3, Ny = 5 and the code is not compiled. Please let me know what I am missing here! Thank you very much :)
This is probably due to bug in MSVC. Matrix and vector operations do not work on windows. I do not know if we have any solution to this problem other than virtual machine / docker.

I see. good to know this. Hope it is fixed soon. Thank you
I don’t think anyone on our side is actively working to improve MSVC support, so I wouldn’t expect patches any time soon.
