clean up

What runtime package failed to install?
Is there a way to manually install it to solve this problem so that I can continue the training process? Thanks.

From the log it seems that the error is because the access to nuget.org server fails. Can you double check if you can visit the following link

https://api.nuget.org/v3/index.json

The output log shows the command to install runtime where you can mannually copy and paste in command window to install runtime manually. If you share the output log file here I can point you to the two command. But you still need access to nuget.org in order to run those command though

Using a web browser, I can connect to https://api.nuget.org/v3/index.json, as shown below.

My output log file is as follows. (Confidential information is replaced with "xxx".)

Please help provide manual installation commands. In addition, can the command be posted to "Developer Command Prompt for VS 2019" and executed directly? Thank you.

@jalin168

You can manually install runtime by running the following commands (you probably need to swap user name from xxx back to actual name)

dotnet restore "c:\program files (x86)\microsoft visual studio\2019\professional\common7\ide\extensions\vwsqrkhn.ye1\AutoMLService\RuntimeManager\torchsharp.cpu.csproj" --configfile "c:\program files (x86)\microsoft visual studio\2019\professional\common7\ide\extensions\vwsqrkhn.ye1\AutoMLService\RuntimeManager\NuGet.config" -r win-x64 /p:UsingToolXliff=false /p:TorchSharpVersion=0.101.5 /p:TorchSharpCudaRuntimeVersion=2.1.0.1 /p:TensorflowRuntimeVersion=2.3.1 /p:BaseIntermediateOutputPath="C:\Users\xxx\AppData\Local\ModelBuilder\torchsharp-cpu-0.101.5\obj"

I executed the first dotnet restore command, but the following error still occurred:

I guessed it was a proxy problem, so I added the proxy settings to C:\Users\xxx\AppData\Roaming\NuGet\NuGet.Config as follows:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <config>
    <add key="http_proxy" value="http://xxx.xxx.xxx:3128" />
    <add key="http_proxy.user" value="xxx" />
    <add key="http_proxy.password" value="xxx" />
  </config>
  <packageSources>
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
  </packageSources>
  <disabledPackageSources>
    <add key="Microsoft and .NET" value="true" />
  </disabledPackageSources>
</configuration>

After executing the command again, a new error occurs as follows:
