openmdao / openmdao1 Goto Github PK

I noticed a difference between OpenMDAO 1.7.1 and OpenMDAO 1.7.2 on the SSBJ test case.

D:\SSBJ-OpenMDAO>pip install openmdao==1.7.1
[...]
D:\SSBJ-OpenMDAO>python ssbj_mdf.py
[...]
R_opt= 3964.01941413

That result is consistent with the reference result.

D:\SSBJ-OpenMDAO>pip install openmdao==1.7.2
[...]
D:\SSBJ-OpenMDAO>python ssbj_mdf.py
[...]
R_opt= 3664.7375274

It seems to me that 1.7.2 release introduced a glitch.

I am trying to build openmdao 1.7.3 for openSUSE, and I am getting the following error in the unit tests with scipy 0.19.0:

Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/testflo/test.py", line 419, in _try_call

    raise ValueError("Objective function must return a scalar")
ValueError: Objective function must return a scalar

The same error happens with the following tests:

• test_simple_array_comp_SLSQP_scaler_unity_eq
• test_simple_array_comp_SLSQP_scaler_unity_ineq

It seems to me to be related to this commit in scipy.

When I type " import openmdao.api" in the command window, Error happened. Can someone help me?

import openmdao.api

Following the installation instructions, I see

~/code/OpenMDAO$ pip install -e OpenMDAO
Directory 'OpenMDAO' is not installable. File 'setup.py' not found.

pip install openmdao seems to work fine.

does the hyperloop plugin works for the latest version of openmdao??

Take the paraboloid example and append this to the end. The check will fail on the partial derivatives. However, if you run it again (un-comment the 3rd line) it will succeed. So it seems that the checks leave the problem in an altered state.

    check_total=top.check_total_derivatives()
    print(check_total)
#    top.run()
    check_partial=top.check_partial_derivatives()
    print(check_partial)

System class has a getitem() method defined which is to be used to access the variable present in it, but the code only raises the following runtime error : "Variable '%s' must be accessed from a containing Group".
Though there is no similar functionality in component or group classes.
Is this a feature to be added later?

So I had a program working great with v.1.4.0. However, I updated to the latest version from github and now my code is broken. I have tested it out and it breaks with commit 6e6e852 on Dec. 2nd, 2015 titled "added checks for src_indices out of bounds of source vec and for negative index values." I get the following error message:

File "/Users/ryanbarr/Documents/RotorSE-BYU_FLOWLab/src/rotorse/main.py", line 41, in

AttributeError: 'int' object has no attribute 'shape'

With some investigation it seems to break in checks.py for params that are pass_by_obj. I have attached an example simple code.
