Description
HI I am trying to execute the below code and getting error every tim 66C2 e
import pystan
model_code = 'parameters {real y;} model {y ~ normal(0,1);}'
model = pystan.StanModel(model_code=model_code) # this will take a minute
y = model.sampling(n_jobs=1).extract()['y']
y.mean()

As per the available suggestions , I have already installed ming-w64 and also updated the
"C:\Users\Dushyant Singh\anaconda3\lib\site-packages\setuptools_distutils\distutils.cfg" with below values
[build]
compiler=mingw32
Every time is providing me the same compiler error .
