1 year ago Hi Ash,
I have not seen this issue before, but it appears to be related to multiprocessing on OSX. I have had issues with OSX compatibility before and thought that I had fixed the problem by using 'spawn' to create new processes.
In order to be able to debug this a little more, can you please let me know some more details of your operating system and the python environment you are using?
If you run aegean --versions, this will give me a snapshot of the modules you are using, but any extra information would be really helpful.

Hi Paul,
I have followed the steps for the installation and successfully installed the latest version 2.3.0, however I cant seem to run BANE.
I am using a MacBook and this is the error I get:

Do you know how I can fix this issue?
Many thanks,
