F# Interactive configuration for Machine Learning tasks

F# tricks

  • Use 64-bit configuration. At Visual Studio switch 'Tools/Options/F# tools/F# Interactive/64-bit F# Interactive' should be "true"
  • Tune Fsi.exe and FsiAnyCPU.exe configuration in “c:\Program Files (x86)\Microsoft SDKs\F#<version>\Framework<version>\” ** — specifies whether the common language runtime runs server garbage collection. ** — specifies whether the common language runtime runs garbage collection on a separate thread. ** — on 64-bit platforms, enables arrays that are greater than 2 gigabytes (GB) in total size.
