An example is shown below: .. code-block:: json [ {"parameter": {"x": 0.5, "y": 0.9}, "value": 0.03}, {"parameter": {"x": 0.4, "y": 0.8}, "value": 0.05}, {"parameter": {"x": 0.3, "y": 0.7}, "value": 0.04} ] Every element in the top level list is a sample. For our built-in tuners/advisors, each sample should have at least two keys: ``parameter`` and ``value``. The ``parameter`` must match this experiment's search space, that is, all the keys (or hyperparameters) in ``parameter`` must match the keys in the search space. Otherwise, tuner/advisor may have unpredictable behavior. ``Value`` should follow the same rule of the input in ``nni.report_final_result``\ , that is, either a number or a dict with a key named ``default``. For your customized tuner/advisor, the file could have any json content depending on how you implement the corresponding methods (e.g., ``import_data``\ ). You also can use `nnictl experiment export <#export>`__ to export a valid json file including previous experiment trial hyperparameters and results. Currently, following tuner and advisor support import data: .. code-block:: yaml builtinTunerName: TPE, Anneal, GridSearch, MetisTuner builtinAdvisorName: BOHB *If you want to import data to BOHB advisor, user are suggested to add "TRIAL_BUDGET" in parameter as NNI do, otherwise, BOHB will use max_budget as "TRIAL_BUDGET".

In local mode, nnictl will set --logdir=[NNI_OUTPUT_DIR] directly and start a tensorboard process. #. In remote mode, nnictl will create a ssh client to copy log data from remote machine to local temp directory firstly, and then start a tensorboard process in your local machine.
