Running MLBoxes on windows machines.

Docker and other MLCommons-Box runners assume they run in Linux environment. Several updates are required to support windows machines as well. Let's use this thread to track what is required and also document the process of running boxes on windows.

__How to run docker-based MLBoxes on Windows machines?

• Do this ...
• Do that ...

Fixed:

• docker run command #134.

To be fixed:

• docker inspect command that uses /dev/null. Error:

  Could not find a part of the path 'C:\dev\null'
  

  Seems like it should either be removed for windows platform (that /dev/null), or the docker runner needs to be able to figure out where it runs (cmd, power shell). Depending on environment, either NUL or $null are used.
• The function that creates mount points needs to be updated. Currently, for file names the following is generated:

  mounts:
      C:\mlperf\mlbox_11062020\box_examples\mnist\workspace/parameters: '/mlbox_io1/C:\mlperf\mlbox_11062020\box_examples\mnist\workspace/parameters'
  

• Paths on a command line need to be quoted.

Start by locating the Docker runner code that handles docker inspect, mount-point creation, and command-line paths, then reproduce the listed failures on a Windows machine. Check how /dev/null, Windows path separators, and quoting are currently handled. Done means Docker-based MLBoxes run on Windows without these errors and the Windows setup process is documented in this issue.
