使用 pyFMI 模拟时出现 CVodeError
CVodeError while simulating with pyFMI
我尝试在 Anaconda (Python 3.6.8) 上设置 pyFMI
安装了 pyFMI 站点上列出的所有必需软件包。 fmu 加载时没有问题，但是当我尝试模拟 fmu 时出现错误：
Could not find cannot import name 'radau5'
Could not find cannot import name 'dopri5'
Could not find cannot import name 'rodas'
Could not find cannot import name 'odassl'
Could not find ODEPACK functions.
Could not find RADAR5
Could not find GLIMDA.

Kelamahim，你是如何安装 PyFMI 包的？我用过
conda install -c chria pyfmi
它有效。
仅有的
Could not find RADAR5
Could not find GLIMDA 显示在执行中，但我的模型有效。希望这有帮助。
我一直在使用 Anaconda2 (Conda 4.6.8/python 2.7.15)。安装过程如下：
- FMIL 是使用 CMake
从 source code 构建的
- pyfmi 通过
conda install -c chria pyfmi 安装
- assimulo 通过
conda install -c conda-forge assimulo 安装
- wxPython 2.8.12.1（经典版）是通过 Windows 安装程序安装的 sourceforge
- 可以从
pip 安装其他依赖项
我在python中加载pyfmi后也看到了以下警告信息，但我的模拟似乎没有受到影响：
Could not find cannot import name radau5
Could not find cannot import name dopri5
Could not find cannot import name rodas
Could not find cannot import name odassl
Could not find ODEPACK functions.
Could not find RADAR5
Could not find GLIMDA.
HTH
pyFMi 也可以从 conda-forge 频道获得：
https://anaconda.org/conda-forge/pyfmi
我永久添加了该频道，因为它具有可重现的构建和大量的包，因此通常可以解决依赖关系。
以下对我有用，在 Anaconda3 中 Python 3.6:
conda config --append channels conda-forge
conda install pyfmi
conda list
解决方案是降级到 Anaconda 3 Python 3.6.2 并使用 conda 安装 pyfmi 版本 2.4.0
