机器学习服务器远程会话设置失败

Question

我想为 R 远程会话设置机器学习服务器。不幸的是它失败了 "Unknown Error"。这是我所做的以及我得到的输出。

设置

安装 Microsoft Machine Learning Server 9.3.0 - 离线安装/使用 R，不使用 Python。

说明来自 Offline installation for Machine Learning Server for Windows

安装步骤成功

MSI (s) (50:78) [09:50:07:880]: Product: Microsoft R Server -- Installation completed successfully.

配置

R 远程会话的配置。

说明来自 Launch the administration tool/CLI to manage the operationalization configuration。

这里是 az ml admin bootstrap 的输出：

D:\R-Server\PYTHON_SERVER\python.exe is not a program. Please install Python 3.5 there if you would like to use Python Functionality.

很奇怪，即使在安装过程中没有选择，它也会尝试执行 python.exe。

问题是 Microsoft 机器学习服务器设置中的错误。如果您在设置期间取消选择 Python，将错误地创建配置文件 ...\o16n\Microsoft.MLServer.ComputeNode\appsettings.json。

你必须更换：

"Python": {},

来自

"Python": {
  "JupyterKernelGateway": {
    "Port": 8888,
    "Enabled": false,
    "KernelName": "MLO16N"
  },
  "SubProcess": {
    "Enabled": false,
    "Path": null
  }
},

那么计算节点就可以启动成功了。
