从mnist看tensorflow运行方式

不打扰是莪最后的温柔 提交于 2019-12-05 07:50:22
目录 目录 tensorflow是如何运行的 有向图 会话 Tensor 变量与常量 用fetches取出数据用feeds输入数据 tensorflow是如何运行的: 将计算流程表示成图 通过sessions执行图的计算 数据表示为张量(tensors) 用Variables表示状态(如权重) 分别使用feeds和fetches来填充和取出数据 有向图: tensorflow的计算是由图表示的。下面是一个mnist例子改编的例子,用于展示tensorflow的有向图定义,也用于展示tensorboard的用法。 节点:节点如layer1,cross_entropy代表的是运算,input也可以看做是输入操作 有向箭头表示数据的流向 从图中可以看出,输入数据之后,可以通过tf.reshape()函数对于输入的张量进行reshape;也可以构造一个网络:网络第一层:layer1, drop_out层,第二层:layer2,然后计算交叉熵(利用input,layer2的数据),计算准确率(利用input,layer2)。我们获得了除每一层维度之外所有有关计算的信息。 import tensorflow as tf from tensorflow.examples.tutorials.mnist import input_data max_steps = 1000 learning

placeholder的样式设置

怎甘沉沦 提交于 2019-12-05 06:57:44
placeholder的样式设置 在input框中有时想将输入的字和placeholder设为不同的颜色或其它效果,这时就可以用以下代码来对placeholder进行样式设置了。 ::-webkit-input-placeholder{} /* 使用webkit内核的浏览器 */ :-moz-placeholder{} /* Firefox版本4-18 */ ::-moz-placeholder{} /* Firefox版本19+ */ :-ms-input-placeholder{} /* IE浏览器 */ 注1:冒号前写对应的input或textarea元素等。 注2:placeholder属性是css3中新增加的属性,IE9和Opera12以下版本的CSS选择器均不支持占位文本。 eg: css代码 #input-test{ color: #FFC0CB; font-size: 1.2em; width: 180px; height: 36px; } #input-test::-webkit-input-placeholder{ color: #ADD8E6; } #input-text::-moz-placeholder{ //不知道为何火狐的placeholder的颜色是粉红色,怎么改都不行,希望有大牛路过帮忙指点 color: #ADD8E6; } #input

Jquery Validate: How To Ignore Placeholder Text (Produce Error on Default/Blank)

丶灬走出姿态 提交于 2019-12-05 05:53:41
问题 I'd like to make jquery validate ignore the default text. The way I have it check for default text is to check if the element.value == the elements alt text Here's my code, but it returns invalid no matter if its blank, default text, or any other text: $.validator.addMethod("notDefaultText", function(value) { if($(this).val()==$(this).attr('alt')) return false; }); rules: { Name: "required notDefaultText", Email: "required notDefaultText email" }, 回答1: I had the same problem and solved it

Jquery Validate Incompatible with Placeholder Polyfill? [IE9 Bug]

﹥>﹥吖頭↗ 提交于 2019-12-05 05:42:23
问题 I'm currently using the Placeholder Polyfill by Mathias Bynens in combination with the jquery.validate plugin (v1.11.1) and am running into a frustrating error with Internet Explorer 9 . I cannot get required field validation to work on my type="password" fields if they have a non-empty placeholder attribute defined. Once a value is input and the placeholder text disappears, the remaining validation works fine. Live Demo of this code can be found here JS $('input').placeholder(); // init

Paste a chart from Excel to a specific placeholder in a specific layout. Powepoint 2010

非 Y 不嫁゛ 提交于 2019-12-05 04:35:51
问题 I need to paste multiple charts from excel to powerpoint. I found some excellent VBA code (mainly on Jon Peltier's site). Now my powerpoint template has a number of layouts (e.g. with 1 chart occupying most of the slides or 1 chart and one text box in a slide, etc etc). What I want is the chart to become part of the slide layout so that if I reformat the slide - e.g. I change the layout as in the example given above - the chart will move accordingly. Currently I am able to paste in the spot

Symfony2 Validator message: Which variables are available?

时光总嘲笑我的痴心妄想 提交于 2019-12-05 03:50:50
At this moment I am implementing validation using the Symfony Validator component using Annotations in my Entity class. The Symfony documentation shows you can use certain placeholders to pass variables through a message and these messages can be translated by the Translator component. So for example, it's possible to write the following annotation: /** * Assert\Length( * min = 5, * max = 10, * minMessage = "Title too short: {{ limit }}", * maxMessage = "Title too long: {{ limit }}" */ protected $title; This works fine, but I was wondering what kinds of placeholders are available to you? Is it

表单控件 下面是一个Bootstrap支持的表控件以及自定义类的完整列表。额外的文档对每个组都是可用的。 类 作用 支持的变量 .form-group 表单控件的任一组 用在任何块级元素上,比如说 <fieldset> 或 <div> .form-control 文本域控件 text 、 password 、 datetime 、 datetime-local 、 date 、 month 、 time 、 week 、 number 、 email 、 url 、 search 、 tel 、 color 选择菜单 multiple 、 size 多行文本域 N/A .form-control-file 文件上传控件 file .radio .radio-inline .checkbox .checkbox-inline 复选框和单选钮 N/A PS:镇山之宝!例子在后续使用中来写!那么一长串的例子,吓死宝宝了。 表单布局 因为Bootstrap对几乎所有的表单控件都应用了 display:block 以及 width:100% ,所以表单默认是纵向堆叠的。可以用附加的类来基于表单改变这种布局。 表单组 .form-group类是向表单添加一些结构的最简单的方法。可是使用在<fieldset>、<div>甚至别的元素上。 <fieldset> 定义围绕表单中元素的边框。

How to display placeholder's text in HTML5's number-typed input

我们两清 提交于 2019-12-05 02:27:51
Is there a way I can show placeholder text inside an input tag of type=number? Detailed Q: The property 'placeholder' of an HTML's input tag is used to show description about the input tag in the UI when the element is not focused - the descriptive text goes blank when the same field gets focus. The problem is no text is visible if the input type is made of type="number". I do have space limitations in my UI and cannot afford a label before the input tag. Any suggestions? Placeholders aren't intended as labels for input. Placeholder should contain examples of valid input. So in case of a

AngularJS: ng-placeholder not working

I have the following input html element that I want to change the placeholder of depending on what is being held in my user model. <input type="text" class="form-control" id="Username" name="Username" data-ng-model="user.Username" required="" ng-placeholder="{{user.AdAccount ? 'Username' : 'Ad Login'}}"> I even tried this method that is said to have worked in previous versions of angular, but no success. ng-placeholder="user.AdAccount == true && 'Username' || 'AD Login'" At the moment my placeholder just appears completely blank. I also know that AdAccount is holding true/false correctly
