kandi X-RAY | A2C Summary

A2C is a Python library typically used in Artificial Intelligence, Reinforcement Learning, Deep Learning, Tensorflow applications. A2C has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. However A2C build file is not available. You can download it from GitHub.

An implementation of Synchronous Advantage Actor Critic (A2C) in TensorFlow. A2C is a variant of advantage actor critic introduced by OpenAI in their published baselines. However, these baselines are difficult to understand and modify. So, I made the A2C based on their implementation but in a clearer and simpler way.

Numpy issue with converting list into array

Asked 2021-Jun-07 at 03:36

To begin this topic off I've created a stock market environment that a function can return its observation through this function. The field 'df' is a pandas instance loaded from csv file and I am returning a step (row) of the data frame to get the data which return its value on the data sheet. My issue is when I set the data to the observation field it return different values then the data sheet.

Reward of Pong game - (OpenAI gym)

Asked 2021-Feb-25 at 06:41

I know that the Pong Game initializes to new game when one side scores 20 points.

By the way, the reward shows that it goes down below -20.
Why is that so?

One thing to expect is that after one side gets 20 points, the game is reset by playing one more time. Does the game need to get 21 points to initialize?

(Use 8 workers, A2C, PongNoFrameskip-v4)

The A2C code fails due to the configuration you copied from the PPO trial: "sgd_minibatch_size", "kl_coeff" and many others are PPO-specific configs, which cause the problem when running using A2C.

The error is explained in the "error.txt" in the logdir.

How to sweep many hyperparameter sets in parallel in Python?

Asked 2021-Jan-13 at 02:34

Note that I have to sweep through more argument sets than available CPUs, so I'm not sure if Python will automatically schedule the use of the CPUs depending on their availability or what.

Here is what I tried, but I get an error about the arguments:

ANSWER

Answered 2021-Jan-13 at 02:34

The function in multiprocessing.Pool.map expects one argument. One way to adapt your code is to write a small wrapper function that takes env, alg, and seed as one argument, separates them, and passes them to run.

Another option is to use multiprocessing.Pool.starmap, which allows multiple arguments to be passed to the function.

Does anyone know how to use AWS App2Container(A2C)?

Asked 2020-Oct-01 at 05:44

AWS App2Container (A2C) is a recently launched feature by AWS. It is a CLI tool to help you lift and shift applications that run in your on-premises data centres or on virtual machines so that they run in containers that are managed by Amazon ECS or Amazon EKS. Since there is not much info on the internet about this, apart from the AWS document so does anybody knows how to implement it and what are the dependencies required for it?

This is a fairly new service so most people will be relying on reading at the moment.

Vulnerabilities

No vulnerabilities reported

Install A2C

You can download it from GitHub.
You can use A2C like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.

Support

This implementation allows for using different environments. It's not restricted to OpenAI gym environments. If you want to attach the project to another environment rather than that provided by gym, all you have to do is to inherit from the base class BaseEnv in envs/base_env.py, and implement all the methods in a plug and play fashion (See the gym environment example class). You also have to add the name of the new environment class in A2C.py\env_name_parser() method.
