无法为PYMC模型编译设置-fbracket-深度参数

Question

我正在尝试在 Mac 上训练 pymc 模型（版本 4.4.0）。 我的模型相当复杂，似乎当前的复杂程度导致编译器出现一些问题，因为我收到了此错误

该错误建议我“使用-fbracket-深度 = N 来增加最大嵌套级别”。 我尝试通过多种方式将该标志添加到我的代码中。 我尝试过添加

export CFLAGS="-fbracket-depth=1024"
export CXXFLAGS="-fbracket-depth=1024"

到我的.zshrc。 我尝试过添加这个

os.environ['CFLAGS'] = "-fbracket-depth=1024"
os.environ['CXXFLAGS'] = "-fbracket-depth=1024"

在编译模型之前查看我的 python 代码。 我什至尝试过在 python 代码中以这种方式添加它：

aesara.config.cxx = "/usr/bin/clang++ -fbracket-depth=1024"

当我尝试使用环境变量（前两种方式）添加它时，它似乎根本没有被识别，并且我得到了与以前相同的错误。 当我将其添加到

aesara.config.cxx

时，我收到此错误：

无论如何，我需要找到一种方法在模型编译期间实际修改此参数。 我怎样才能做到这一点？

Answer 1

尝试像这样添加它：

aesara.config.gcc__cxxflags = f"-fbracket-depth={fbracket_depth}"
aesara.config.cxx = "/usr/bin/clang++"

这有效吗？
