尝试在 MS Windows 上运行它时出现"mlflow ui"错误

Question

当我运行mlflow ui时，出现以下错误：

Traceback (most recent call last):
File "c:anaconda3librunpy.py", line 193, in _run_module_as_main

我使用了anaconda+python 3.6.5，安装了git，并用C:Program FilesGitbingit.exe和C:Program FilesGitcmd设置了路径。

我安装了带有pip install mlflow的mlflow，它的版本是0.2.1。

我在环境变量中设置了一个名为GIT_PYTHON_GIT_EXECUTABLE、值为C:Program FilesGitbingit.exe的变量。

我该如何解决这个问题？

Answer 1

首先卸载'mlflow'和'servatory'，然后再次安装'mlflow'。现在尝试它工作

Answer 2

mlflow文档已经说明

注意2：我们目前不支持在Windows上运行MLflow。尽管如此，我们将感谢为MLflow做出的任何贡献在Windows上工作得更好。

您遇到了fcntl问题：它在MS Windows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"。(请参见https://stackoverflow.com/a/1422436/236007了解更多详细信息。(

解决这个问题需要相应地修改mlflow的源代码。

Answer 3

我遇到了同样的问题，这些步骤对我有效：

• pip卸载mlflow
• pip-m虚拟环境名称
• pip安装conda
• pip安装mlflow
• mlflow ui-->信息：女服务员：上桌http://127.0.0.1:5000
