Description

For parallel sampling it does not work unless something is sent to standard output (see #5827), with this hack still not working on Pycharm, but works on VS code and Jupyter.

Contributor guide

Research direction
Examine the SMC progressbar implementation in parallel sampling, understand why stdout output is required, reproduce the issue in different environments (PyCharm, VS Code, Jupyter), and find a more robust way to update the progress bar, such as using shared memory or a progress bar library that supports multiprocessing.
