4.0.3

ML.NET 4.0.3

Bug Fixes

  • [release/4.0] Improve unique directory generation for temp files (#​7528)

    • Compatibility note: This change resolves a performance problem where past versions of ML.NET would leave behind folders with the pattern ml_dotnet\d+ in the temp directory, which would cause model opening performance to degrade. This fixes the problem. You may also wish to delete these empty folders once after updating.

      Using powershell:

      Get-ChildItem "$env:TEMP" -Directory -Filter "ml_dotnet*" | Remove-Item -Recurse -Force

      Using Bash:

      find "$TEMP" -type d -name "ml_dotnet*" -exec rm -rf {} +

Build / Test updates

  • [release/4.0] Update dependencies from dotnet/arcade (#​7470)
  • [release/4.0] Use arcade script for installing MacOS dependencies (#​7534)
