Can’t find a way to display progression of sampling, and it is very problematic for sampling that takes several minutes. This feature seems to exist in RStan, but I can’t find it in PyStan. Any advice appreciated.

Do you use Jupyter Notebook/Lab? See in the console. This problem is fixed with PyStan3

PyStan3 uses tqdm to show the progress. Does tqdm work normally in your IDE?

It’s look like tqdm works perfectly fine for an easy exemple : [image] When I’m using STAN, the sampling result is good, but no progress bar appears : [image]

Ok, you are using PyStan 2. I’m not sure how Spyder handles C++ output. Try with setting verbose=True

Ok you’re right I use PyStan 2, is there a PyStan 3 stable release and if so, do you know where I can find it ? I don’t see it on the website. Also, I tried with verbose = True and it doesn’t work either.
