Advanced Saving and Loading
---------------------------------
In this example, we show how to use some advanced features of Stable-Baselines3 (SB3):
how to easily create a test environment to evaluate an agent periodically,
use a policy independently from a model (and how to save it, load it) and save/load a replay buffer.
By default, the replay buffer is not saved when calling ``model.save()``, in order to save space on the disk (a replay buffer can be up to several GB when using images).
However, SB3 provides a ``save_replay_buffer()`` and ``load_replay_buffer()`` method to save it separately.
.. image:: ../_static/img/colab-badge.svg
:target: https://colab.research.google.com/github/Stable-Baselines-Team/rl-colab-notebooks/blob/sb3/advanced_saving_loading.ipynb
Stable-Baselines3 automatic creation of an environment for evaluation.
For that, you only need to specify ``create_eval_env=True`` when passing the Gym ID of the environment while creating the agent.
Behind the scene, SB3 uses an :ref:`EvalCallback <callbacks>`.
.. code-block:: python
from stable_baselines3 import SAC
from stable_baselines3.common.evaluation import evaluate_policy
from stable_baselines3.sac.policies import MlpPolicy
# Create the model, the training environment
# and the test environment (for evaluation)
model = SAC('MlpPolicy', 'Pendulum-v0', verbose=1,
learning_rate=1e-3, create_eval_env=True)
# Evaluate the model every 1000 steps on 5 test episodes
# and save the evaluation to the "logs/" folder
model.learn(6000, eval_freq=1000, n_eval_episodes=5, eval_log_path="./logs/")
# save the model
model.save("sac_pendulum")
# the saved model does not contain the replay buffer
loaded_model = SAC.load("sac_pendulum")
print(f"The loaded_model has {loaded_model.replay_buffer.size()} transitions in its buffer")
# now save the replay buffer too
model.save_replay_buffer("sac_replay_buffer")
# load it into the loaded_model
loaded_model.load_replay_buffer("sac_replay_buffer")
# now the loaded replay is not empty anymore
print(f"The loaded_model has {loaded_model.replay_buffer.size()} transitions in its buffer")
# Save the policy independently from the model
# Note: if you don't save the complete model with `model.save()`
# you cannot continue training afterward
policy = model.policy
policy.save("sac_policy_pendulum.pkl")
# Retrieve the environment
env = model.get_env()
# Evaluate the policy
mean_reward, std_reward = evaluate_policy(policy, env, n_eval_episodes=10, deterministic=True)
print(f"mean_reward={mean_reward:.2f} +/- {std_reward}")
# Load the policy independently from the model
saved_policy = MlpPolicy.load("sac_policy_pendulum")
# Evaluate the loaded policy
mean_reward, std_reward = evaluate_policy(saved_policy, env, n_eval_episodes=10, deterministic=True)
print(f"mean_reward={mean_reward:.2f} +/- {std_reward}")
Accessing and modifying model parameters
----------------------------------------
You can access model's parameters via ``load_parameters`` and ``get_parameters`` functions,
or via ``model.policy.state_dict()`` (and ``load_state_dict()``),
which use dictionaries that map variable names to PyTorch tensors.
These functions are useful when you need to e.g. evaluate large set of models with same network structure,
visualize different layers of the network or modify parameters manually.
Policies also offers a simple way to save/load weights as a NumPy vector, using ``parameters_to_vector()``
and ``load_from_vector()`` method.
Following example demonstrates reading parameters, modifying some of them and loading them to model
by implementing `evolution strategy (es) <http://blog.otoro.net/2017/10/29/visual-evolution-strategies/>`_
for solving the ``CartPole-v1`` environment. The initial guess for parameters is obtained by running
A2C policy gradient updates on the model.

)
# Use traditional actor-critic policy gradient updates to
# find good initial parameters
model.learn(total_timesteps=10000)
# Include only variables with "policy", "action" (policy) or "shared_net" (shared layers)
# in their name: only these ones affect the action.
# NOTE: you can retrieve those parameters using model.get_parameters() too
mean_params = dict(
(key, value)
for key, value in model.policy.state_dict().items()
if ("policy" in key or "shared_net" in key or "action" in key)
)
# population size of 50 invdiduals

.. _export:
Exporting models
================
After training an agent, you may want to deploy/use it in another language
or framework, like `tensorflowjs <https://github.com/tensorflow/tfjs>`_.
Stable Baselines3 does not include tools to export models to other frameworks, but
this document aims to cover parts that are required for exporting along with
more detailed stories from users of Stable Baselines3.
Background
----------
In Stable Baselines3, the controller is stored inside policies which convert
observations into actions. Each learning algorithm (e.g. DQN, A2C, SAC)
contains a policy object which represents the currently learned behavior,
accessible via ``model.policy``.
Policies hold enough information to do the inference (i.e. predict actions),
so it is enough to export these policies (cf :ref:`examples <examples>`)
to do inference in another framework.
.. warning::
When using CNN policies, the observation is normalized during pre-preprocessing.
This pre-processing is done *inside* the policy (dividing by 255 to have values in [0, 1])
Export to ONNX

TODO: help is welcomed!

(using PyTorch JIT)
TODO: help is welcomed!
Export to tensorflowjs / ONNX-JS
--------------------------------
TODO: contributors help is welcomed!
Probably a good starting point: https://github.com/elliotwaite/pytorch-to-javascript-with-onnx-js
Manual export
-------------
You can also manually export required parameters (weights) and construct the
network in your desired framework.
You can access parameters of the model via agents'
:func:`get_parameters <stable_baselines3.common.base_class.BaseAlgorithm.get_parameters>` function.
As policies are also PyTorch modules, you can also access ``model.policy.state_dict()`` directly.
To find the architecture of the networks for each algorithm, best is to check the ``policies.py`` file located
in their respective folders.
.. note::
In most cases, we recommend using PyTorch methods ``state_dict()`` and ``load_state_dict()`` from the policy,
unless you need to access the optimizers' state dict too. In that case, you need to call ``get_parameters()``.

.. _save_format:
On saving and loading
=====================
Stable Baselines3 (SB3) stores both neural network parameters and algorithm-related parameters such as
exploration schedule, number of environments and observation/action space. This allows continual learning and easy
use of trained agents without training, but it is not without its issues. Following describes the format
used to save agents in SB3 along with its pros and shortcomings.
Terminology used in this page:
- *parameters* refer to neural network parameters (also called "weights"). This is a dictionary
mapping variable name to a PyTorch tensor.
- *data* refers to RL algorithm parameters, e.g. learning rate, exploration schedule, action/observation space.
These depend on the algorithm used. This is a dictionary mapping classes variable names to their values.
Zip-archive
-----------
A zip-archived JSON dump, PyTorch state dictionaries and PyTorch variables. The data dictionary (class parameters)
is stored as a JSON file, model parameters and optimizers are serialized with ``torch.save()`` function and these files
are stored under a single .zip archive.
Any objects that are not JSON serializable are serialized with cloudpickle and stored as base64-encoded
string in the JSON file, along with some information that was stored in the serialization. This allows
inspecting stored objects without deserializing the object itself.
This format allows skipping elements in the file, i.e. we can skip deserializing objects that are
broken/non-serializable.
.. This can be done via ``custom_objects`` argument to load functions.
File structure:
::
saved_model.zip/
├── data JSON file of class-parameters (dictionary)
├── *.optimizer.pth PyTorch optimizers serialized
├── policy.pth PyTorch state dictionary of the policy saved
├── pytorch_variables.pth Additional PyTorch variables
├── _stable_baselines3_version contains the SB3 version with which the model was saved
Pros:
- More robust to unserializable objects (one bad object does not break everything).
- Saved files can be inspected/extracted with zip-archive explorers and by other languages.
Cons:
- More complex implementation.
- Still relies partly on cloudpickle for complex objects (e.g. custom functions)
with can lead to `incompatibilities <https://github.com/DLR-RM/stable-baselines3/issues/172>`_ between Python versions.

Hyperparameters from the `gSDE paper <https://arxiv.org/abs/2005.05719>`_ were used (as they are tuned for PyBullet envs).
*Gaussian* means that the unstructured Gaussian noise is used for exploration,
*gSDE* (generalized State-Dependent Exploration) is used otherwise.
