gym atari游戏的环境设置问题:Breakout-v0, Breakout-v4, BreakoutNoFrameskip-v4和BreakoutDeterministic-v4的区别

如题: 首先是v0和v4的区别:带有v0的env表示会有25%的概率执行上一个action,而v4表示只执行agent给出的action,不会重复之前的action。 带有Deterministic的env表示固定跳4帧,否则跳帧数随机从(2, 5)中采样。 带有NoFrameskip-v4的env表示没有跳帧,且不会重复执行上一个action。 参考链接 来源: CSDN 作者: ok_kakaka 链接: https://blog.csdn.net/clksjx/article/details/104053216

React redux-actions

倾然丶 夕夏残阳落幕 提交于 2020-01-19 02:02:53
// npm install --save redux-actions 1:作用: 当我们的在开发大型应用的时候,对于大量的action,我们的reducer需要些大量的swich来对action.type进行判断。 redux-actions可以简化这一烦琐的过程,它可以是actionCreator,也可以用来生成reducer, 其作用都是用来简化action、reducer。 主要函数有createAction、createActions、handleAction、handleActions、combineActions。 createAction 原来创建: export const getCeshi = options = > { return { type: [ MINE ] , payload: request ( services.data ) , } } 现在: import { createActions } from 'redux-actions' import { MINE, MINE2 } from '@/constants' export const getMine = createActions ( { [ MINE ] : options = > options, [ MINE2 ] : options = > options, // [ MINE

截器和过滤器的区别

不羁的心 提交于 2020-01-17 13:09:33
截器和过滤器的区别 拦截器和过滤器的区别: 1、拦截器是基于java的反射机制的,而过滤器是基于函数回调 2、过滤器依赖与servlet容器,而拦截器不依赖与servlet容器 3、拦截器只能对action请求起作用,而过滤器则可以对几乎所有的请求起作用 4、拦截器可以访问action上下文、值栈里的对象,而过滤器不能 5、在action的生命周期中,拦截器可以多次被调用,而过滤器只能在容器初始化时被调用一次 拦截器 :是在面向切面编程的就是在你的service或者一个方法前调用一个方法,或者在方法后调用一个方法比如动态代理就是拦截器的简单实现,在你调用方法前打印出字符串(或者做其它业务逻辑的操作),也可以在你调用方法后打印出字符串,甚至在你抛出异常的时候做业务逻辑的操作。 下面通过实例来看一下过滤器和拦截器的区别: 使用拦截器进行/admin 目录下jsp页面的过滤 <package name="newsDemo" extends="struts-default" namespace="/admin"> <interceptors> <interceptor name="auth" class="com.test.news.util.AccessInterceptor" /> <interceptor-stack name="authStack"> <interceptor

问题 This is a calculator App. When I try and compile it comes up with the following message unreported exception javax.script.ScriptException; must be caught or declared to be thrown I have a feeling it is because the class is set as ActionEvent . I am a student so I am still learning :) Any ideas? Thanks \ 回答1: You can do the following: // .. other imports import javax.script.ScriptException; // .. the rest of your code if(source==buteq){ try{ ScriptEngineManager manager = new

Edit Download Link on Woocommerce thank you page

被刻印的时光 ゝ 提交于 2020-01-16 16:48:12
问题 I'm trying to work out how to edit the download button link that sits directly underneath the order title, in the order details section of the thank you page. So if you make an order in Woocommerce, for a product that is downloadable, you get a " Thank you. Your order has been received " box, then under it, you get an " Order Details " box. In that order details box, it shows each product ordered, and if that product is downloadable, it shows a small " Download: Product name " link under the

Rasa custom actions not connected

帅比萌擦擦* 提交于 2020-01-16 04:18:08
问题 So, I just started with Rasa this week, but I’m quite happy with the results so far, as in that it responds well et cetera. However, I now have custom actions in an actions.py file, but when I’m in the rasa shell it seems to miss that file entirely and asks for another input. (see the image below) It doesn't even give an error. What am I doing wrong? I tried to run "rasa run actions" in another terminal, with an action_endpoint in the endpoints.yml file. In the endpoints file: `action

原文: https://www.yuque.com/yuxuanbeishui/zog1rm/tgmgws 今天我们就来聊聊 dva 中的 effects 与 reducers以及其中涉及的关键字的使用。如果它们之间工作流程还不太熟悉,请阅读: 分析models源码 为了让小伙伴们更好的理解与使用 effects 与 reducers,我们依然找现有的 models 为例: 位置:"/src/pages/Profile/models/profile.js" <div class="lake-codeblock-content"><div class="CodeMirror"><pre class="cm-s-default"><span class="lake-preview-line"><span class="lake-preview-line-number lake-lm-pad-level-1"></span><span class="lake-preview-codeblock-content"><span class="cm-keyword">import</span> { <span class="cm-def">queryBasicProfile</span>, <span class="cm-def">queryAdvancedProfile</span> }

Unable to set form action via javascript (error:object doesn't support this property or method)

隐身守侯 提交于 2020-01-15 03:08:25
问题 Here is the code. patient is the form name. function settarget(page) { document.getElementById('patient').action = page; } The exact error message from IE is: SCRIPT438: Object doesn't support this property or method I have also tried it referencing document.forms[0].action - same error. There is no duplication of the name patient for any other tag. This works with Chrome and Firefox, but not IE8 on XP or IE9 on Win7. Is there a security setting in IE that is blocking this action? 回答1: DOM
