在mlflow上运行"mlflow ui“时出错

Question

当我运行mlflow ui时，发生了以下错误：

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

我使用anaconda +python3.6.5，使用C:\Program Files\Git\bin\git.exe和C:\Program Files\Git\cmd安装了git并设置了path。

我安装了mlflow，pip install mlflow的版本为0.2.1。

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

我怎么才能解决这个问题？

Answer 1

mlflow文档已经说过

注2:我们目前不支持在Windows上运行MLflow。尽管如此，我们还是希望能为使MLflow在Windows上更好地工作做出任何贡献。

您遇到了fcntl问题:它在MS平台上不可用，因为它是POSIX兼容系统上可用的fcntl函数的“包装器”。(有关更多细节，请参见https://stackoverflow.com/a/1422436/236007。)

解决这个问题需要相应地修改mlflow的源代码。

首先卸载'mlflow‘和’侍应生‘，然后再安装'mlflow’.Now --尝试使用它
