windows 上的“mlflow ui”出现 fcntl 错误 - mlflow 1.0

Question

我在尝试 mlflow 示例和运行 'mlflow ui'.

时收到以下错误消息

错误：

ModuleNotFoundError: No module named 'fcntl' Running the mlflow server failed. Please see the logs above for details

有人知道这个问题的解决方案吗？

我已经尝试了 https://github.com/mlflow/mlflow/pull/1080

中建议的解决方案

没有成功。替换 mlflow 源代码中的修改文件，它引发了其他问题，因为找不到它正在寻找的内容如下：

Answer 1

刚刚解决了问题：由于某些原因，运行环境中没有安装waitress。安装后，一切似乎都可以正常使用上面问题中链接的解决方案#1080。

在执行mlflow ui命令前先进行如下安装： pip 安装女服务员
