Issues running get_pulse.py on osx (10.10) #28

Closed orgicus closed 9 years ago

orgicus commented 9 years ago

Hi,

This looks great, but I've been having some issues running the code. I've activated openmdao in the downloads folder then tried to run the get_pulse.py script but I run into these errors:

Any ideas on how initialise these variables and get script running ?

Thanks, George

I hit the same thing in Ubuntu last night. Did you test your openmdao installation? For some reason openmdao 12 tests gave me warnings. I downgraded to openmdao-10.3.2 and everything worked fine. cf https://github.com/thearn/webcam-pulse-detector/issues/29

Yeah, changes in OpenMDAO 0.12 require that all array variables be pre-sized before execution, which causes trouble in this application as-is. But using an earlier version of the framework (or running from the no_openmdao branch) will work for now.
