Hello, I've been using PyFR on a windows laptop with Cygwin 64bit, and
after upgrading pyfr to 1.3, I get an error which seems to persist even
when I downgrade back to 1.2.
$ pyfr run -b openmp -p euler_vortex_2d.pyfrm euler_vortex_2d.ini

since it refers to prefork, I thought it would be an issue with pytools,
but changing versions of that seemed to not have any affect.
It may be worth noting that for v1.1 and 1.2 I've downloaded the program
and used setup.py install, but for 1.3 my mentor suggested using pip -e and
then pip. after creating a few virtual environments, I'm not sure how to
approach the problem.
