有没有办法为Jupyter Notebook会话设置PYTHONHASHSEED？ [英] Is there a way to set PYTHONHASHSEED for a Jupyter Notebook session?

问题描述

我想禁用 Python的 hash 功能。根据此主题（无法查看或修改PYTHONHASHSEED的值），则在运行时通过设置 os.environ ['PYTHONHASHSEED'] 来设置PYTHONHASHSEED不起作用。运行Jupyter Notebook时如何将PYTHONHASHSEED设置为固定值？

I want to disable the randomization of Python's hash function. According to this thread (Unable to see or modify value of PYTHONHASHSEED through a module), setting PYTHONHASHSEED by setting os.environ['PYTHONHASHSEED'] at runtime does not work. How can I set PYTHONHASHSEED to a fixed value when I run Jupyter Notebook?

推荐答案

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

You can try to modify the kernel.json and add the line "env": {"PYTHONHASHSEED":"0"}. The file is located in your python-folder or virtual environment at:

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

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。

That solves the issue for me.
