I need openmdao on windows 8 to run an aerostructutal optimization code that uses it but I’m having issues in the installation process. I installed numpy and scipy through pip in the cmd and then also openmdao using pip install openmdao but when I try to run a .py with copied inside the code at the bottom of this page, I get an error about “Component” not being found to import. What am I doing wrong ?

    your question is a bit incomplete. Could you please include the full error msg and code you're trying to run? Also, could you more clearly list the steps you did to install things? – Justin Gray May 30 '18 at 15:04
  • The error I get is: Traceback (most recent call last): ** IDLE Internal Exception: File "C:\Python34\lib\idlelib\run.py", line 353, in runcode exec(code, self.locals) File "C:\Users\Patrizio\Desktop\run.py", line 3, in from openmdao.api import Group, Problem, Component, IndepVarComp ImportError: cannot import name 'Component' The code I'm trying to run is the one on this page of openmdao documentation (which I forgot to link before): http://openmdao.readthedocs.io/en/1.7.3/usr-guide/basics.html – user9870949 May 30 '18 at 16:27

Some codes are written for a specific version of OpenMDAO. If you are using OpenAeroStruct, it requires OpenMDAO 1.7.4, not OpenMDAO 2.2.x.

To obtain the correct version, you would need to use the command pip install openmdao==1.7.4 or to download and install the source directly from here: https://github.com/OpenMDAO/openmdao1, following the instructions on the README, not on readthedocs.

  • I actually tried that and got the code running (I need openaerostruct for my analysis), thanks anyway for the support – user9870949 May 30 '18 at 22:11
