OpenMDAO: pyOptSparse构建脚本

Question

因此，我将打开这个关于如何构建pyOptSparse并在OpenMDAO框架中使用它的新线程。OpenMDAO团队发布了一份清单，应该通过集成IPOPT来构建pyOptSparse：https://github.com/OpenMDAO/build_pyoptsparse

我在Ubuntu虚拟机上遵循了他们的指示。不幸的是，当涉及到运行纸片时，出现了一些问题，并阻止了pyOptSparse的安装。

我不知道我是不是忘了什么，但我被卡住了。有人知道如何解决这个问题吗？

非常感谢您的帮助。下面是我得到的奇怪错误消息：

文件"/usr/local/lib/python3.9/subprocess.py"，第528行，在run raise中(retcode，process.args，subprocess.CalledProcessError:命令‘./subprocess.CalledProcessError’，‘-with-metis’，‘-with-metis-l之母=-L/root/pyoptsparse/lib -lcoinmetis'，’-metis-c之旗=-w-i/root/pyopts解译/包含-i/root/pyopts解译/包含/硬币-I/root/pyoptsparse/include /metis‘，’-前缀=/root/prefix‘，‘'CFLAGS=-w -I/root/pyoptsparse/include -I/root/pyoptsparse/include /投币-或-i/root/pyoptsparse/include/投币-或/metis’FCFLAGS=-参数不匹配-I/root/pyoptsparse/include/pyoptsparse/include/硬币-或-i/root/pyopts解译/包含/metis‘返回的非零退出状态1。

编辑:所以我运行了两次build_pyoptsparse -v :第一次我收到一条错误消息，它告诉我包LAPCK丢失了。因此，我做了一个apt安装libblas-dev liblapack-dev来安装它。然后，我再次运行pyopts解析式命令，得到如下结果：

build_pyoptsparse脚本打算以普通用户而不是root用户的身份运行--它还没有通过这种方式进行测试，并且可能会对您的系统产生意外的影响。

理想情况下，它应该在虚拟Python环境中运行，无论是使用conda (Anaconda / miniconda / miniforge)还是使用venv。在conda环境中，可以从存储库安装几个包，而不必构建它们。如果在虚拟环境之外运行，它将安装在您的主目录下。精确的路径可以用-p修改。

话虽如此，你的截图中并没有太多的信息，只有一个错误发生了。如果您的系统上已经安装了不同版本的METIS，则可能会导致腮腺炎配置出现问题。尝试删除另一个版本的METIS并重新构建。如果仍然收到错误，请运行build_pyoptsparse -v，以便打印完整的错误文本，并在这里发布。

当我试图安装这个软件包时，我遇到了一个类似的问题，将它与openmdao/dymos一起使用。我使用Linux和Conda22.9.0。以下是我为完全设置我的环境所遵循的步骤，对所有提示都是肯定的：

#Create and activate new environment with python 3.10 and pip
conda create -n py310
conda activate py310
conda install python=3.10
conda install pip

关闭外壳并重新打开它

# install dymos
conda activate py310
git clone https://github.com/OpenMDAO/dymos.git ./dymos.git
python -m pip install -e dymos.git
# install build_pyoptsparse
git clone https://github.com/OpenMDAO/build_pyoptsparse.git
python -m pip install ./build_pyoptsparse
# install gfortran and swig as they will be required by build_pyoptsparse
conda install -c conda-forge gfortran
conda install -c anaconda swig
# install MUMPS, METIS, and IPOPT using the conda-forge channel
conda install -c conda-forge MUMPS
conda install -c conda-forge METIS
conda install -c conda-forge IPOPT
# run build_pyoptsparse
build_pyoptsparse -v
