'tqdm' object has no attribute 'disable’ (users with Mac OS and Python3.7+ affected)

[ghost]

When running MCMC I get an AttributeError: 'tqdm' object has no attribute 'disable’. This occurs in macOS (current version, 11.6) and Python >= 3.8. The error does not seem to arise in earlier versions of Python, in particular in 3.7.12.

I am afraid this is a possible bug in 'tqdm'. See tqdm/tqdm#487

This seems to be out of my competence and I do not have the time to investigate in depth how this can be fixed in 'tqdm'. I hope that the 'tqdm' developers will fix this soon. Perhaps you can open an issue in their git-hub?

FYI, I cannot reproduce the problem under Linux/Ubuntu with Python3.8 and 3.9, but indeed the problem appears in Mac OS. I suspect this is somehow connected with how python3 handles multiprocessing/multithreading on Mac OS.

A fix could be to simply tun-off the progress bar when running NS/MCMC

git pull, and try again.

Please report if this is a potential workaround!

Unchecking MCMC progress bar seems to work in versions newer than Python 3.7.12. The MCMC analysis is performed while the Stdout/Stderr does not display any message.

The problem looks indeed within macOS and the handling of multiprocessing in Python3.8 and newer. This thread in Stackoverflow supports this thesis, as I could reproduce both the problem and the solution.

Any development on the "tqdm" side on this?

Looks like the thread regarding this issue (tqdm/issues/487) is now closed, as brianbruggeman provided a working solution. Maybe this helps for now.

This does not seem a general solution within tqdm. @ccifuentesr, when you have time, can you update your tqdm and Exo-Striker and try to reproduce the bug?

This seems to be old and already fixed external bug, thus closing.
