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“未知的错误”。这是我所做的和我作为产出得到的。

设置

安装微软机器学习服务器9.3.0 -离线安装/与R，没有Python。

来自Windows下机器学习服务器的脱机安装的指令

安装步骤成功

MSI (50:78) 09:50:07:880: Product: Microsoft --成功完成安装。

配置

R远程会话的配置。

来自启动管理工具/CLI来管理操作化配置的指令。

这里是来自az ml admin bootstrap的输出

D:\R-Server\R_SERVER\o16n\Microsoft.MLServer.ComputeNode>az ml admin bootstrap

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.

奇怪的是，即使在安装过程中没有被选中，它也尝试执行python.exe。

问题是设置中有一个错误。如果在安装过程中取消选择Python，配置文件...\o16n\Microsoft.MLServer.ComputeNode\appsettings.json将被错误地创建。

你必须替换：

"Python": {},

通过

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

然后计算节点将成功启动。
