From 3438ce7e09502cfa212dad97e22594ac62b17ff2 Mon Sep 17 00:00:00 2001 From: Chris McCarthy Date: Thu, 6 Jul 2023 11:35:44 +0100 Subject: [PATCH] #1386 - Updated tests in test_seeding_and_deterministic_session.py to use TempPrimaiteSession. - Added test_seeded_learning test and test_deterministic_evaluation test. - Passed config values seed and deterministic to ppo agent - Dropped deterministic override in evaluate functions - TempPrimaiteSession now writes files to a UUID folder rather than datetime - Added seed to Ray RLlib agent setup in rllib.py - Added seed to SB3 agent setup in sb3.py --- src/primaite/agents/agent.py | 1 + src/primaite/agents/rllib.py | 1 + src/primaite/agents/sb3.py | 10 +- .../ppo_not_seeded_training_config.yaml | 155 ++++++++++++++++++ .../{e2e => }/ppo_seeded_training_config.yaml | 0 tests/conftest.py | 1 - .../test_session_repeatability.py | 57 ------- tests/mock_and_patch/get_session_path_mock.py | 5 +- .../test_seeding_and_deterministic_session.py | 57 +++++++ 9 files changed, 222 insertions(+), 65 deletions(-) create mode 100644 tests/config/ppo_not_seeded_training_config.yaml rename tests/config/{e2e => }/ppo_seeded_training_config.yaml (100%) delete mode 100644 tests/e2e_integration_tests/test_session_repeatability.py create mode 100644 tests/test_seeding_and_deterministic_session.py diff --git a/src/primaite/agents/agent.py b/src/primaite/agents/agent.py index 4b39839a..5b76c36b 100644 --- a/src/primaite/agents/agent.py +++ b/src/primaite/agents/agent.py @@ -248,6 +248,7 @@ class AgentSessionABC(ABC): agent.session_path = path + return agent else: diff --git a/src/primaite/agents/rllib.py b/src/primaite/agents/rllib.py index 30edd93c..dcb1f5c5 100644 --- a/src/primaite/agents/rllib.py +++ b/src/primaite/agents/rllib.py @@ -106,6 +106,7 @@ class RLlibAgent(AgentSessionABC): timestamp_str=self.timestamp_str, ), ) + self._agent_config.seed = self._training_config.seed self._agent_config.training(train_batch_size=self._training_config.num_steps) self._agent_config.framework(framework="tf") diff --git a/src/primaite/agents/sb3.py b/src/primaite/agents/sb3.py index 17fbe0a6..0d031c10 100644 --- a/src/primaite/agents/sb3.py +++ b/src/primaite/agents/sb3.py @@ -59,6 +59,7 @@ class SB3Agent(AgentSessionABC): verbose=self.sb3_output_verbose_level, n_steps=self._training_config.num_steps, tensorboard_log=str(self._tensorboard_log_path), + seed=self._training_config.seed ) def _save_checkpoint(self): @@ -98,20 +99,18 @@ class SB3Agent(AgentSessionABC): def evaluate( self, - deterministic: bool = True, **kwargs, ): """ Evaluate the agent. - :param deterministic: Whether the evaluation is deterministic. :param kwargs: Any agent-specific key-word args to be passed.
