• cannot import name 'binary_weighted_focal_crossentropy' from 'keras.backend'

  im trying to follow this tutorial = https://github.com/tensorflow/agents/blob/master/docs/tutorials/9_c51_tutorial.ipynb

• Trying to apply the TensorFlow agents from the examples to a custom environment
  1 project | /r/tensorflow | 9 Jan 2022

  I followed the TensorFlow tutorial for agents and the multi armed bandit tutorial and now I'm trying to make one of the already implemented agents, from the examples, work on my own environment. Basically my environment exists of 5 actions and 5 observations. Applying one action i results in the same state i. One action contains another step of sending that action number to a different program via a socket and the answer from the program is interpreted for the reward. My environment seems to be working, I used the little test script below to test the observe and action functions. I know this is not a full proof but showed its atleast working.

• DD-PPO, TD3, SAC: which is the best?
  3 projects | /r/reinforcementlearning | 3 Dec 2021

  Depending on what task you pick the "best" algo will vary. There are also a bunch of variations and tricks for each of those, some of which have been given new names over time. If you are working on a project I would suggest whichever one has the simplest and most extendable implementation. If you really want to compare all of them you can use libraries that have them all implemented, such as tfagents.

• Help understanding PPO training performance

  I'm using a simple training loop, based on this.

• I need suggestions to improve my project
  3 projects | /r/github | 6 Sep 2021

  Hello everyone, I published my python project a month ago, it's a command line interface for training, tuning and reusing reinforcement learning algorithms in tensorflow 2.x. It's similar to stable-baselines, tf-agents, and not so many others. It seems like it's not getting enough attention despite the README, license, and everything else.

• xagents, a new reinforcement learning library in TF2

• tf-agents throws ValueError: Layer dense layer expects 1 input(s), but it received 4 input tensors when using custom environment with OpenAI Gym
  3 projects | /r/learnmachinelearning | 7 Jul 2021

  Well it seems it doesn't flatten anything, just passes OrderedDict as input dense. Not sure but apparently it's keras that makes that a list of tensors. You can dig around places like https://github.com/tensorflow/agents/blob/v0.8.0/tf_agents/networks/network.py https://github.com/tensorflow/agents/blob/v0.8.0/tf_agents/agents/dqn/dqn_agent.py https://github.com/openai/gym/blob/master/gym/spaces/dict.py if you want to be really sure.

• [D] Choosing best parameters from an optimization
  3 projects | /r/MachineLearning | 5 Jun 2021

  2- You could go the reinforcement learning approach by controlling these parameters using an agent. This would mean that the parameters would have to change on the fly, which I am not sure if appropriate. If so, creating a gym environment is not so hard, which would then use something like tf.agents , rlax or any other rl framework of your liking.

• "Modern" version of OpenAI's spinning up?
  1 project | /r/reinforcementlearning | 4 Jun 2021

  Not the same style and looks somehow more complicated but i want to mention tf.agents if you don't know about it already.
