kandi X-RAY | stable-baselines3 Summary

stable-baselines3 is a Python library typically used in Artificial Intelligence, Reinforcement Learning, Deep Learning, Pytorch applications. stable-baselines3 has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has medium support. You can install using 'pip install stable-baselines3' or download it from GitHub, PyPI.

Stable Baselines3 (SB3) is a set of reliable implementations of reinforcement learning algorithms in PyTorch. It is the next major version of Stable Baselines. You can read a detailed presentation of Stable Baselines3 in the v1.0 blog post or our JMLR paper. These algorithms will make it easier for the research community and industry to replicate, refine, and identify new ideas, and will create good baselines to build projects on top of. We expect these tools will be used as a base around which new ideas can be added, and as a tool for comparing a new approach against existing ones. We also hope that the simplicity of these tools will allow beginners to experiment with a more advanced toolset, without being buried in implementation details. Note: despite its simplicity of use, Stable Baselines3 (SB3) assumes you have some knowledge about Reinforcement Learning (RL). You should not utilize this library without some practice. To that extent, we provide good resources in the documentation to get started with RL.

            Rollout summary statistics not being monitored for CustomEnv using Stable-Baselines3
            Asked 2022-Apr-11 at 16:15

            I am trying to train a custom environment using PPO via Stable-Baselines3 and OpenAI Gym. For some reason the rollout statistics are not being reported for this custom environment when I try to train the PPO model.

            The code that I am using is below ( I have not included the code for the CustomEnv for brevity):

            SOLVED: There was an edge case where the environment was not ending, and the done variable remained False indefinitely.

            After fixing this bug, the Rollout statistics reappeared.

            What are vectorized environments in reinforcement learning?
            Asked 2022-Mar-25 at 10:37

            I'm having a hard time wrapping my head around what and when vectorized environments should be used. If you can provide an example of a use case, that would be great.

            Documentation of vectorized environments in SB3: https://stable-baselines3.readthedocs.io/en/master/guide/vec_envs.html

            Answered 2022-Mar-25 at 10:37

            Vectorized Environments are a method for stacking multiple independent environments into a single environment. Instead of executing and training an agent on 1 environment per step, it allows to train the agent on multiple environments per step.

            Usually you also want these environment to have different seeds, in order to gain more diverse experience. This is very useful to speed up training.

            I think they are called "vectorized" since each training step the agent observes multiple states (inserted in a vector), outputs multiple actions (one for each environment), which are inserted in a vector, and receives multiple rewards. Hence the "vectorized" term

            To quote the github readme:

            Note: Stable-Baselines supports Tensorflow versions from 1.8.0 to 1.14.0. Support for Tensorflow 2 API is planned.

            The same github readme also recommends to use stable-baselines3, as stable-baselines is currently only being maintained and its functionality is not extended. Thus, I would not expect the TF1 -> TF2 update any time soon.

            If you can not install this version of tensorflow, I suggest to use stable-baselines3 and follow the examples. The code you posted above is not consistent with the stable-baselines3 docs, which import the MlpPolicy as

            I am trying using Webots in combination with stable-baselines3 for reeinforcment-learning purpose. I tried using Webot with multiple instances, but connecting the controller to a specific one doesn't work. It mostly connects to the newest one.

            ANSWER

            Answered 2021-Sep-09 at 06:35

            The WEBOTS_PID environment variable should be set before you start the robot controller, otherwise it is not taken into account. So, you cannot set it in the runtime.ini (which is anyhow ignored when launching extern controllers) nor in the controller itself. I would recommend you to write a script that sets the WEBOTS_PID first and then starts the controller program as an extern controller.
