Question

我收到一些我无法解决的错误。有人可以帮我弄这个吗？这是我的代码。

提前致谢

NameError：全局名称＆＃39; dis1＆＃39;未定义

Answer 1

因为您是从openmdao.main.api导入的，所以您似乎正在尝试使用非常旧版本的openMDAO（＆lt; 0.13.X）。

您需要将代码更新为OpenMDAO 1.x，因为不再支持旧版本。

Answer 2

我尝试安装openmdao-0.13.0，但无法解析https：\ conda.binstar.org。

当我尝试安装较低版本时，它很容易安装。对更高版本有什么具体要求吗？

Answer 3

我也遇到了Anaconda的问题。我在Fedora 25盒子上运行。相反，我必须首先手动安装每个依赖项，然后是openmdao。现在一切都很完美，但这是一件苦差事。
