Code works line-by-line in Spyder, but not when the whole script is run
I've installed pystan and am trying to verify that the installation has worked correctly.
When I go to the IPython console in Spyder and run the following code line by line, it generates the correct answer.
import pystan
model_code = 'parameters {real y;} model {y ~ normal(0,1);}'
model = pystan.StanModel(model_code=model_code)
y = model.sampling().extract()['y']
y.mean()
The line calling pystan.StanModel takes about 30 seconds, while the other lines execute instantaneously. In the end I get the right result (about 0, e.g. 0.01 or -0.01).
However, when I run the code as a single script in Spyder, it doesn't work, and instead the console just runs forever, doesn't produce a result, and I have to manually shut down Anaconda. Why is that?

(Spyder maintainer here) You probably need to addpystantoTools > Preferences > Python Interpreter > User Module Reloader > Set UMR excluded (not reloaded) modules. Please let me know if that works so we can exclude it by default.

Unfortunately that didn't work. I added pystan, then restarted Anaconda and Spyder and checked that it was still added to UMR excluded. As before, the code works if executed line by line but when I run all the code as a single script nothing happens (aside from a lot of CPU noise) and I need to restart the kernel.
