在Ubuntu 18.04上安装JModelica

3
你好,JModelica社区。我已经成功在CentOS上编译了JModelica,但是在Ubuntu 18.04上仍然失败了。编译本身是成功的,但运行时...
from pyjmi.examples import cstr_casadi
cstr_casadi.run_demo()

失败原因

我尝试降级了几个软件包,但问题仍然存在。顺便说一下,我在Arch Linux上也遇到了同样的错误。
我知道Ubuntu 18.04并没有得到官方支持,但我希望有人已经找到了解决这个问题的方法。

我将回答自己的问题以标记为已解决。解决方案来自@Vital(请参见原问题的评论)。
为了使JModelica在Ubuntu 18.04或Arch Linux上工作,所有受影响的Python文件中的需要替换为。

看起来你加载了错误的casadi版本。 你能检查一下输出吗?

from casadi import __version__
print(__version__)

问题可能与swig版本有关。

将solver_object.output替换为solver_object.getOutput应该会有所帮助!例如:

primal_opt = N.array(self.solver_object.output(casadi.NLP_SOLVER_X)) 

使用

primal_opt = N.array(self.solver_object.getOutput(casadi.NLP_SOLVER_X))

也许这个变更集:https://trac.jmodelica.org/changeset/8074 对于文件和位置的概述会有所帮助。


你能添加一些日志吗? 例如: make casadi_interface -j4 2> make-casadi-errors.txt - Vital
我添加了来自make installmake casadi_interface的日志。 - Yannick
也许将solver_object.output替换为solver_object.getOutput会有所帮助!例如: primal_opt = N.array(self.solver_object.output(casadi.NLP_SOLVER_X)) 替换为 primal_opt = N.array(self.solver_object.getOutput(casadi.NLP_SOLVER_X)) - Vital
哇,这真的起作用了!我不得不在几个文件和位置中将solver_object.output替换为solver_object.getOutput。你能提供一个官方答案吗,这样我就可以标记它为已解决了吗? - Yannick
