OK...I need some help with what I think is an amazingly simple problem. Essentially, I'm trying to recast a script of mine to use optparse. Now, to do this, I've been following examples for optparse on the web. These usually use the:
def main():
...bits...
if __name__ == "__main__":
main()
construct. So, I took a script that did work and recast it into this first. In doing so, I took my usual
job_server = pp.Server(ncpus=0, ppservers=ppservers)
statements and put them inside main(). But that seemed to mess with the script as I started getting errors like:
Traceback (most recent call last):
File "/.automount/home/home/scratch/thompsma/OptParse/3atom-optparse.py", line 741, in <module>
main()
File "/.automount/home/home/scratch/thompsma/OptParse/3atom-optparse.py", line 670, in main
run_incore2=run_incore2)
File "/.automount/home/home/scratch/thompsma/OptParse/3atom-optparse.py", line 153, in do_fitness
jobs.append((alpha_set,job_server.submit(eval_alphas_molecular,
NameError: global name 'job_server' is not defined
Now, I'm pretty sure my optparse bits are working since I made a separate file and tested them out. So, all the variables like the port number now occur in the same variables and I don't think they're the problem. My only guess is that it's the starting of PP inside of main(). And that leads into the whole global/local stuff I've never quite got my hand on in python.
Help.
