Hi Manosh, this looks like exactly the error that https://git.ligo.org/lscsoft/bilby/-/merge_requests/1274 resolves. This update has not been included in a release and is planned for release with v2.2.0, hopefully later this week.
I'll note, however, that Python 3.8 will not be supported for that release unless we backport this bugfix.

Dear Bilby team,
I am Manosh, and Bilby has been instrumental in conducting parameter estimation for my cosmological model. Although I am not well-versed in Python or gravitational waves, I have become a regular user of the Bilby library. Presently, I am utilizing Bilby version 2.1.1 with Python 3.8 for my research.
Recently, I encountered a challenge while attempting to employ the pool option in the emcee sampler for my analyses. Specifically, I faced difficulties when running the code provided at ( https://git.ligo.org/lscsoft/bilby/-/merge_requests/341).
I am reaching out to the Bilby community for guidance and support in understanding and resolving the issue related to the pool option. Any assistance or suggestions you could provide would be immensely valuable to me.
Additionally, as per the guidance of Dr. Matthew Pitkin, I tried using the npool option with the emcee sampler. It appears to have worked, as I observed the message "22:16 bilby INFO : Setting up multiprocessing pool with 8 processes" during execution, with all 8 cores active. However, the main error encountered was "NotImplementedError: pool objects cannot be passed between processes or pickled". For clarity, I have affixed the output.
Thank you for your time and support.
Best regards, Manosh
