# dopamine-rl 3.1.7 Webots 整合
###### tags: dopamine
> Pypi: https://pypi.org/project/dopamine-rl/

## 使用須知
27/07/2020: Dopamine now runs on TensorFlow 2. However, Dopamine is still written as TensorFlow 1.X code. This means your project may need to explicity disable TensorFlow 2 behaviours with:

import tensorflow.compat.v1 as tf
tf.disable_v2_behavior()

if you are using custom entry-point for training your agent. The migration to TensorFlow 2 also means that Dopamine no longer supports Python 2.

## 安裝須知
OS: Ubuntu 18.04

Webots採用撰文時間最新版本[R2020b-rev1](https://github.com/cyberbotics/webots/releases/tag/R2020b-rev1)
