NNI on Windows (experimental feature)

Running NNI on Windows is an experimental feature. 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-tfv1\config_windows.yml

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

FAQ

simplejson failed when installing NNI

Make sure C++ 14.0 compiler installed.

building 'simplejson._speedups' extension error: [WinError 3] The system cannot find the path specified

Trial failed with missing DLL in command line or PowerShell

This error caused by missing LIBIFCOREMD.DLL and LIBMMD.DLL and fail to install SciPy. Using Anaconda or Miniconda with Python(64-bit) can solve it.

ImportError: DLL load failed

Trial failed on webUI

Please check the trial log file stderr for more details.

If there is a stderr file, please check out. Two possible cases are as follows:

  • forget to change the trial command python3 into python in each experiment YAML.
  • forget to install experiment dependencies such as TensorFlow, Keras and so on.

Fail to use BOHB on Windows

Make sure C++ 14.0 compiler installed then try to run nnictl package install --name=BOHB to install the dependencies.
