NNI Client
==========

NNI client is a python API of ``nnictl``\ , which implements the most commonly used commands. Users can use this API to control their experiments, collect experiment results and conduct advanced analyses based on experiment results in python code directly instead of using command line. Here is an example:

.. code-block:: bash

   from nni.experiment import Experiment

   # create an experiment instance
   exp = Experiment() 

   # start an experiment, then connect the instance to this experiment
   # you can also use `resume_experiment`, `view_experiment` or `connect_experiment`
   # only one of them should be called in one instance
   exp.start_experiment('nni/examples/trials/mnist-pytorch/config.yml', port=9090)

   # update the experiment's concurrency
   exp.update_concurrency(3)

   # get some information about the experiment
   print(exp.get_experiment_status())
   print(exp.get_job_statistics())
   print(exp.list_trial_jobs())

   # stop the experiment, then disconnect the instance from the experiment.
   exp.stop_experiment()
