"mlflow ui" 在 MS Windows 上尝试 运行 时出错

Error with "mlflow ui" when trying to run it on MS Windows

当我运行mlflow ui出现以下错误:

我使用 anaconda + python 3.6.5 我安装了 git 并使用 C:\Program Files\Git\bin\git.exeC:\Program Files\Git\cmd.

设置了路径

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

我在环境变量中设置了一个名称为 GIT_PYTHON_GIT_EXECUTABLE、值为 C:\Program Files\Git\bin\git.exe 的变量。

我该如何解决这个问题?

mlflow documentation 已经说过

Note 2: We do not currently support running MLflow on Windows. Despite this, we would appreciate any contributions to make MLflow work better on Windows.

您遇到了 fcntl 问题:它在 MS Windows 平台上不可用,因为它是 fcntl function that's available on POSIX-compatible systems. (See 周围的 "wrapper" 以获取更多详细信息。)

解决这个问题需要相应地修改mlflow的源代码。

首先卸载 'mlflow' 和 'waitress',然后重新安装 'mlflow'。现在试试吧
