Question

尝试mlflow示例并运行'mlflow ui'时，出现以下错误消息。

错误：

ModuleNotFoundError：没有名为“ fcntl”的模块正在运行mlflow服务器失败了请查看上面的日志以获取详细信息

有人知道这个问题的解决方案吗？

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

提出的解决方案

没有成功。将修改后的文件替换为mlflow源代码时，由于以下原因，它会因找不到所需内容而引发其他问题：

Answer 1

仅解决了该问题：由于某种原因，运行环境中未安装女服务员。安装后，问题上方的解决方案＃1080似乎一切正常。

Answer 2

在执行mlflow ui命令之前执行以下安装：点安装女服务员

Windows上带有“ mlflow ui”的fcntl错误-mlflow 1.0
