openmdao:约束不存在，cod中存在值错误

Question

我一直在创建一个项目，以优化最低阻力的飞机形状，并已运行到两个问题，一个与约束发生应用和收到以下错误

 File "/home/name/Desktop/x1ac3opt.py", line 202, in <module>
    top.setup()

  File "/usr/local/lib/python2.7/dist-packages/openmdao/core/problem.py", line 498, in setup
    connections = self._setup_connections(params_dict, unknowns_dict)

  File "/usr/local/lib/python2.7/dist-packages/openmdao/core/problem.py", line 197, in _setup_connections
    connections = self.root._get_explicit_connections()

  File "/usr/local/lib/python2.7/dist-packages/openmdao/core/group.py", line 685, in _get_explicit_connections
    (src, tgt, tgt))

NameError: Source 'p.Sp1' cannot be connected to target 'con.Sp1': 'con.Sp1' does not exist.

这是在引用约束条件时发生的 `你知道吗

File "/home/name/Desktop/x1ac3opt.py", line 63, in solve_nonlinear
    unknowns['Cdi'] = (324/((7750)*(m.pi)*(((Sp1+Sp2+Sp3+Sp4+Sp5)**2)/(Sp1*(Rc+Tc1)/2+Sp2*(Tc1+Tc2)/2+Sp3*(Tc2+Tc3)/2+Sp4*(Tc3+Tc4)/2+Sp5*(Tc4+Tc5)/2))))

  File "/usr/local/lib/python2.7/dist-packages/openmdao/core/vec_wrapper.py", line 435, in __setitem__
    self._dat[name].set(value)

  File "/usr/local/lib/python2.7/dist-packages/openmdao/core/vec_wrapper.py", line 313, in _set_scalar
    self.val[0] = value

ValueError: setting an array element with a sequence.

Answer 1

对于第一个错误：

没有看到你的实际模型，我无法诊断为什么会发生这种情况。但您正试图将IndepVarComp的输出（我猜是）连接到其他组件（可能是exec comp）的输入。您可能已经提升了源、目标或两者。所以你没有提到他们的名字是正确的考虑晋升。你知道吗

如果您已经升级了这两个变量，因为它们都是名称Sp1，那么它们会自动连接起来。如果您只提升了其中一个，那么您需要在connect语句中说明这一点。例如：

self.connect('Sp1', 'con.Sp1')

对于第二个错误： 在Cdi和必须计算值的等式之间存在某种大小不匹配。看起来这个方程可能是标量的，但我不能确定，因为我不知道中间变量是什么。无论如何，该赋值的一边或另一边的大小都不正确。您可以通过添加一些print语句来调试它，以查看OpenMDAO的大小。你知道吗

print(unknowns['Cdi'])
print((324/((7750)*(m.pi)*(((Sp1+Sp2+Sp3+Sp4+Sp5)**2)/(Sp1*(Rc+Tc1)/2+Sp2*(Tc1+Tc2)/2+Sp3*(Tc2+Tc3)/2+Sp4*(Tc3+Tc4)/2+Sp5*(Tc4+Tc5)/2))))))
