Analysis (tune.analysis)
|
|
========================
|
|
|
|
You can use the ``ExperimentAnalysis`` object for analyzing results. It is returned automatically when calling ``tune.run``.
|
|
|
|
.. code-block:: python
|
|
|
|
analysis = tune.run(
|
|
trainable,
|
|
name="example-experiment",
|
|
num_samples=10,
|
|
)
|
|
|
|
Here are some example operations for obtaining a summary of your experiment:
|
|
|
|
.. code-block:: python
|
|
|
|
# Get a dataframe for the last reported results of all of the trials
|
|
df = analysis.results_df
|
|
|
|
# Get a dataframe for the max accuracy seen for each trial
|
|
df = analysis.dataframe(metric="mean_accuracy", mode="max")
|
|
|
|
# Get a dict mapping {trial logdir -> dataframes} for all trials in the experiment.
|
|
all_dataframes = analysis.trial_dataframes
|
|
|
|
# Get a list of trials
|
|
trials = analysis.trials
|
|
|
|
You may want to get a summary of multiple experiments that point to the same ``local_dir``. For this, you can use the ``Analysis`` class.
|
|
|
|
.. code-block:: python
|
|
|
|
from ray.tune import Analysis
|
|
analysis = Analysis("~/ray_results/example-experiment")
