python - 尝试在 MS Windows 上运行“mlflow ui”时出错

问题描述

当我运行mlflow ui时发生以下错误：

Traceback (most recent call last):
  File "c:\anaconda3\lib\runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)

我使用了 anaconda + python 3.6.5 并安装了 git 并使用 and 设置C:\Program Files\Git\bin\git.exe路径C:\Program Files\Git\cmd。

我安装mlflow了 whit pip install mlflow，它的版本是 0.2.1。

我在环境变量中设置了一个具有名称GIT_PYTHON_GIT_EXECUTABLE和值的变量。C:\Program Files\Git\bin\git.exe

我该如何解决这个问题？

解决方案

首先卸载'mlflow'和'waitress'，然后再次安装'mlflow'。现在试试它的工作原理
