Hi,
I'm using pydyna and everyhting is working fine. However, when I try to run the file locally I get an error.
This is how I run the input file:
hostname = "localhost"
port = "5000"
dyna=solver.launch_dyna(ip = hostname,port = port) # connect to the server
dyna.push(output_path_VD) # push an input file
dyna.start_locally(input = "input.k", nproc=20)
and this is my error:
CRITICAL - - dynalogging - handle_exception - Uncaught exception

If anyone could provide some advice that would be amazing.
