Parsing these file during the DB upgrade can break the DB because all experiments may not be executed on the same file system and thus some configuration files may not be present. The space should only be upgraded when the user attempts running an experiment, in which case the configuration file is available. The space does not need to be upgraded during DB upgrade anyway, because experiment built is backward compatible with experiments lacking an explicit space definition in DB (relying on cmdargs and config file to define space at run-time).

It should be disabled by default with warning messages when different versions of experiments are used. Users who wants using advanced features of the EVC would still be able to use it by enabling it. Making it false by default is a breaking change and may cause issues to user currently using the EVC. Based on discussion with users there does not seem to have much usage of the EVC so far so this breaking change should be relatively harmless. Avoiding further confusion by making it disabled by default is worth the breaking change. --- src/orion/core/__init__.py | 8 +++ src/orion/core/cli/evc.py | 11 ++++ .../core/io/experiment_branch_builder.py | 7 ++- src/orion/core/io/experiment_builder.py | 59 ++++++++++++------- src/orion/core/io/resolve_config.py | 6 +- tests/functional/branching/test_branching.py | 52 ++++++++++++++++ 6 files changed, 115 insertions(+), 28 deletions(-) diff --git a/src/orion/core/__init__.py b/src/orion/core/__init__.py index cf0c20df3..1da4d4248 100644 --- a/src/orion/core/__init__.py +++ b/src/orion/core/__init__.py @@ -300,6 +300,14 @@ def define_evc_config(config): # TODO: This should be built automatically like get_branching_args_group # After this, the cmdline parser should be built based on config. + evc_config.add_option( + "enable", + option_type=bool, + default=False, + env_var="ORION_EVC_ENABLE", + help="Enable the Experiment Version Control.

Also, in attempt to solve #576, we will need to duplicate trials that are not completed in parents into executed experiments to allow reserving and executing the trials. This will lead to more potential duplicated trials and raise the important of handling duplicate properly. When fetching from the EVC, we should ignore duplicates from parent or children if the trials are available in current experiment. This will recursively solve the issue during recursive fetch from EVC. This will also simplify the handling of potential duplicates during {naive-}algorithm updates, as there will simply be no duplicates. How: During the call to adaptors, a set of hash is generated from trials of current nodes based on hyperparameter values (ignores experiment id). Any trials from the parents or child that has a hash found in this set of hash will be filtered out. When there is a duplicate, only the trial of the current node is kept. This also applies recursively to call from children experiments to grand-children. --- src/orion/core/evc/experiment.py | 47 +- tests/functional/commands/conftest.py | 8 +- .../commands/test_status_command.py | 84 +-- .../serving/test_trials_resource.py | 18 +- .../core/evc/test_experiment_tree.py | 599 ++++++++++++++++++ 5 files changed, 700 insertions(+), 56 deletions(-) create mode 100644 tests/unittests/core/evc/test_experiment_tree.py diff --git a/src/orion/core/evc/experiment.py b/src/orion/core/evc/experiment.py index 35e5a40ca..c8d8b5ca3 100644 --- a/src/orion/core/evc/experiment.py +++ b/src/orion/core/evc/experiment.py @@ -14,6 +14,7 @@ analyzing an EVC tree.

This is very problematic as non-completed trials of parents cannot be execute anymore unless the environment state is reverted to the one used for parent experiment (ex: resetting code). It should look for executable trials across the EVC tree. Running trials from parent experiments may cause issue if the child experiment has a different script path, different code version or different cmdline call. We should attempt running the trial with the corresponding experiment configuration. It's not clear what to do if it fails. If we simply leave the trial status to interrupted the child experiment will try it again. Another option is to copy the trial to the child experiment and run it with child configuration. If the user checkpointed the trial state with trial.hash_params, the checkpoint will be lost as trial.hash_params will change based on the experiment id. This is safe, protecting users from resuming with a different code version. How: Fetch trials from EVC tree and duplicate any pending trials to current experiment. A hash of the params is used to avoid duplicating trials that are already available in the current experiment. --- src/orion/client/experiment.py | 9 + src/orion/core/worker/experiment.py | 49 ++++++ .../functional/core/worker/test_experiment.py | 160 ++++++++++++++++++ .../client/test_experiment_client.py | 6 + .../unittests/core/worker/test_experiment.py | 16 ++ 5 files changed, 240 insertions(+) create mode 100644 tests/functional/core/worker/test_experiment.py diff --git a/src/orion/client/experiment.py b/src/orion/client/experiment.py index f0a17485a..d23fec775 100644 --- a/src/orion/client/experiment.py +++ b/src/orion/client/experiment.py @@ -294,6 +294,15 @@ def fetch_trials_by_status(self, status, with_evc_tree=False): status, with_evc_tree=with_evc_tree ) + def fetch_pending_trials(self, with_evc_tree=False): + """Fetch all trials with status new, interrupted or suspended + + Trials are sorted based on `Trial.submit_time` + + :return: list of `Trial` objects + """ + return self._experiment.fetch_pending_trials(with_evc_tree=with_evc_tree) + def fetch_noncompleted_trials(self, with_evc_tree=False): """Fetch non-completed trials of this `Experiment` instance. diff --git a/src/orion/core/worker/experiment.py b/src/orion/core/worker/experiment.py index 8cbe623a9..094e90d0a 100644 --- a/src/orion/core/worker/experiment.py +++ b/src/orion/core/worker/experiment.py @@ -16,6 +16,7 @@ from orion.core.evc.adapters import BaseAdapter from orion.core.evc.experiment import ExperimentNode +from orion.core.io.database import DuplicateKeyError from orion.core.utils.exceptions import UnsupportedOperation from orion.core.utils.flatten import flatten from orion.core.utils.singleton import update_singletons @@ -240,6 +241,8 @@ def reserve_trial(self, score_handle=None): self.fix_lost_trials() + self.duplicate_pending_trials() + selected_trial = self._storage.reserve_trial(self) log.debug("reserved trial (trial: %s)", selected_trial) return selected_trial @@ -265,6 +268,43 @@ def fix_lost_trials(self): except FailedUpdate: log.debug("failed") + def duplicate_pending_trials(self): + """Find pending trials in EVC and duplicate them in current experiment. + + An experiment cannot execute trials from parent experiments otherwise some trials + may have been executed in different environements of different experiment although they + belong to the same experiment.

Cardinality computation should account for this otherwise algorithms may get stuck in suggest(). It happened to a user with a prior loguniform(1e-4, 1e-2, precision=2). This gives only 181 possible values. How: If real dimension has precision and prior loguniform, then compute cardinality. There is a problem with transformed space however. A linearized dimension for instance would attempt to compute the cardinality with the linearized bounds. What matters is the smallest cardinality between the transformed space and the original space. The only case where cardinality is smaller in transformed space is when real values are discretized. Therefore, we only compute cardinality of transformed dimensions if transformation lead to integer, otherwise we use the cardinality of the original dimension. --- src/orion/algo/space.py | 57 ++++++++++++++++++++++-- src/orion/core/utils/__init__.py | 19 ++++++++ src/orion/core/worker/transformer.py | 14 +++--- tests/functional/algos/test_algos.py | 8 ++++ tests/unittests/algo/test_space.py | 44 ++++++++++++++++++ tests/unittests/core/test_transformer.py | 8 +++- 6 files changed, 135 insertions(+), 15 deletions(-) diff --git a/src/orion/algo/space.py b/src/orion/algo/space.py index d738d22e5..7dda2d584 100644 --- a/src/orion/algo/space.py +++ b/src/orion/algo/space.py @@ -35,6 +35,8 @@ import numpy from scipy.stats import distributions + +from orion.core.utils import float_to_digits_list from orion.core.utils.points import flatten_dims, regroup_dims logger = logging.getLogger(__name__) @@ -319,7 +321,7 @@ def shape(self): _, _, _, size = self.prior._parse_args_rvs( *self._args, # pylint:disable=protected-access size=self._shape, -

How: Loop over the EVC and call `fix_lost_trials` for each experiments. Note that this can increase significantly the cost of the command for large EVC. A ugly hack is used to allow running `fix_lost_trials` on the parents that are in read mode. It would be great to find a better work around... --- src/orion/core/evc/experiment.py | 4 +++ src/orion/core/worker/experiment.py | 24 ++++++++++++++-- src/orion/testing/__init__.py | 10 +++++++ src/orion/testing/evc.py | 9 +++--- tests/conftest.py | 10 ++++++- .../core/worker/test_experiment_functional.py | 28 +++++++++++++++---- tests/unittests/core/conftest.py | 9 +----- 7 files changed, 74 insertions(+), 20 deletions(-) diff --git a/src/orion/core/evc/experiment.py b/src/orion/core/evc/experiment.py index c8d8b5ca3..63a4c92ee 100644 --- a/src/orion/core/evc/experiment.py +++ b/src/orion/core/evc/experiment.py @@ -151,6 +151,10 @@ def fetch_pending_trials(self): """See :meth:`orion.core.evc.experiment.ExperimentNode.recurvise_fetch`""" return self.recurvise_fetch("fetch_pending_trials") + def fetch_lost_trials(self): + """See :meth:`orion.core.evc.experiment.ExperimentNode.recurvise_fetch`""" + return self.recurvise_fetch("fetch_lost_trials") + def fetch_noncompleted_trials(self): """See :meth:`orion.core.evc.experiment.ExperimentNode.recurvise_fetch`""" return self.recurvise_fetch("fetch_noncompleted_trials") diff --git a/src/orion/core/worker/experiment.py b/src/orion/core/worker/experiment.py index 094e90d0a..2109b7ab5 100644 --- a/src/orion/core/worker/experiment.py +++ b/src/orion/core/worker/experiment.py @@ -247,7 +247,7 @@ def reserve_trial(self, score_handle=None): log.debug("reserved trial (trial: %s)", selected_trial) return selected_trial - def fix_lost_trials(self): + def fix_lost_trials(self, with_evc_tree=True): """Find lost trials and set them to interrupted.
