Question

我想禁用randomization of Python's hash function。根据该线程（Unable to see or modify value of PYTHONHASHSEED through a module），在运行时通过设置~ (user folder) ~/Documents ~/Documents/useanimal ~/Documents/useanimal/UseDog.java ~/Downloads ~/Downloads/animal ~/Downloads/animal/Dog.java来设置PYTHONHASHSEED不起作用。运行Jupyter Notebook时如何将PYTHONHASHSEED设置为固定值？

Answer 1

您可以尝试修改kernel.json并添加行"env": {"PYTHONHASHSEED":"0"}。该文件位于您的python文件夹或虚拟环境中，位于：

[venv|python-folder]/share/jupyter/kernels/python3/kernel.json

kernel.json：

{
     "argv": [
      "python",
      "-m",
      "ipykernel_launcher",
      "-f",
      "{connection_file}"
     ],
     "display_name": "Python 3",
     "language": "python",
     "env": {"PYTHONHASHSEED":"0"}
}

那为我解决了这个问题。

Answer 2

尝试添加

％env PYTHONHASHSEED = 0

输入您的代码。详细信息：

有没有办法为Jupyter Notebook会话设置PYTHONHASHSEED？
