MLFlow跟踪ui没有在本地机器(膝上型电脑)上显示实验

Question

我是mlflow的初学者，并试图使用Anaconda 3在本地设置它。我在anaconda中创建了一个新的环境，并在其中安装mlflow和sklearn。现在，我使用jupyter笔记本来运行mlflow的示例代码。

使用上面的代码，我能够成功地创建3个不同的实验，因为我可以看到在我的本地目录中创建的文件夹，如下所示：

在这里输入图像描述

现在，我试图在我的chrome浏览器中使用jupyter终端运行mlflow ui，并且我能够打开mlflow ui，但无法看到和实验如下所示：

在这里输入图像描述

你能帮我找出我哪里出错了吗？

Answer 1

在哪里运行mlflow ui命令？

我认为如果您在参数中传递跟踪ui路径，它将工作：

mlflow ui --backend-store-uri file:///Users/Swapnil/Documents/LocalPython/MLFLowDemo/mlrun
