[英]Pyomo Compatibility with Python 3.11
Is there a known compatibility issue with pyomo
and python 3.11
? pyomo
和python 3.11
是否存在已知的兼容性问题?
Just trying out the latest/greatest python release and importing pyomo
is failing with pyomo v 6.4.2:只是尝试最新/最好的 python 版本并导入
pyomo
失败与 pyomo v 6.4.2:
Python 3.11.0 (v3.11.0:deaf509e8f, Oct 24 2022, 14:43:23) [Clang 13.0.0 (clang-1300.0.29.30)] on darwin

Pyomo 6.4.2 isn't compatible with python 3.11. Pyomo 6.4.2 与 python 3.11 不兼容。 You need to update to 6.4.3, which was released on 28th November 2022.
您需要更新到 2022 年 11 月 28 日发布的 6.4.3。
Verion 6.4.2 does some stuff with pickle and the __getstate__
/ __setstate__
functions. Verion 6.4.2 使用 pickle 和
__getstate__
/ __setstate__
函数做了一些事情。 However, Python 3.11 introduced a default implementation for these functions that does not match Pyomo's expectations.然而,Python 3.11 引入了这些功能的默认实现,这与 Pyomo 的期望不符。 So the whole thing falls over.
所以整个事情都失败了。
See this note on the new default implementation for __getstate__
.请参阅有关__getstate__的新默认实现的
__getstate__
。
Classes can further influence how their instances are pickled by overriding the method getstate ().
类可以通过覆盖方法getstate () 进一步影响它们的实例如何被 pickle。 It is called and the returned object is pickled as the contents for the instance, instead of a default state. There are several cases:
它被调用,返回的 object 被 pickle 为实例的内容,而不是默认的 state。有几种情况:
For a class that has no instance
__dict__
and no__slots__
, the default state isNone
.对于没有实例
__dict__
和__slots__
的 class,默认的 state 是None
。For a class that has an instance
__dict__
and no__slots__
, the default state isself.__dict__
.对于具有实例
__dict__
且没有__slots__
的 class ,默认 state 是self.__dict__
。For a class that has an instance
__dict__
and__slots__
, the default state is a tuple consisting of two dictionaries:self.__dict__
, and a dictionary mapping slot names to slot values.对于具有实例
__dict__
和__slots__
的 class ,默认 state 是一个由两个字典组成的元组:self.__dict__
和一个将插槽名称映射到插槽值的字典。 Only slots that have a value are included in the latter.后者仅包含具有值的插槽。
For a class that has
__slots__
and no instance__dict__
, the default state is a tuple whose first item is None and whose second item is a dictionary mapping slot names to slot values described in the previous bullet.对于具有
__slots__
且没有实例__dict__
的 class,默认 state 是一个元组,其第一项为 None,其第二项是将插槽名称映射到上一条项目符号中所述的插槽值的字典。Changed in version 3.11: Added the default implementation of the
__getstate__()
method in the object class.在 3.11 版更改:在 object class 中添加了
__getstate__()
方法的默认实现。
In the v6.4.2 code base you can see it does a check to see if __getstate__
is implemented or not.在 v6.4.2 代码库中,您可以看到它会检查
__getstate__
是否已实现。 https://github.com/Pyomo/pyomo/blob/6.4.2/pyomo/core/base/component.py#L467 https://github.com/Pyomo/pyomo/blob/6.4.2/pyomo/core/base/component.py#L467
In the main branch, this code has recently been changed.在主分支中, 此代码最近已更改。 And there is a recent commit saying that the code is now 3.11 compatible.
最近有一个提交说代码现在与 3.11 兼容。 So just hang tight, and wait for the new version to be release.
因此,请稍等片刻,等待新版本的发布。
Or if you really cannot wait and just want to experiment, then install the development version of 6.4.3 with git:或者,如果你真的等不及了,只想试验一下,那就用 git 安装 6.4.3 的开发版:
eg.例如。
pip install git+https://github.com/Pyomo/pyomo.git@main
NB.注意。 Obviously, you'll need git installed to be able to do this.
显然,您需要安装 git 才能执行此操作。 And do not use this to install pyomo for production code.
并且不要使用它来安装生产代码的 pyomo。 This is code that is under development and has not yet been released.
这是正在开发中的代码,尚未发布。
