NNI on Windows (experimental feature)

Currently we support local, remote and pai mode on Windows. Windows 10.1809 is well tested and recommended.

Installation on Windows

please refer to Installation for more details.

When these things are done, use the config_windows.yml configuration to start an experiment for validation.

nnictl create --config nni\examples\trials\mnist\config_windows.yml

For other examples you need to change trial command python3 into python in each example YAML.
