I'm new to this so please forgive me if I forget to add enough information. I have an MCMC code that uses emcee and that works perfectly fine in my "normal" terminal, with the Python 3.5.2 version. Recently, I started using Spyder within Anaconda and the code does not work, in particular I get this error:
Traceback (most recent call last):
File "/opt/anaconda3/lib/python3.9/multiprocessing/process.py", line 315, in
_bootstrap
self.run()
File "/opt/anaconda3/lib/python3.9/multiprocessing/process.py", line 108, in run
self._target(*self._args, **self._kwargs)

return _ForkingPickler.loads(res)
AttributeError: Can't get attribute 'lnprob' on <module '__main__' (built-in)
"lnprob" is the function where I calculate the posterior distribution. I assume the error has to do with the multiprocessing, but don't know how to solve it. The python version I have in the environment is Python 3.9.7.
Many thanks
