我正在阅读卷积神经网络教程.我希望在训练模型后可视化每层的输出.例如,在函数"evaluate_lenet5"中,我想将一个实例(它是一个图像)传递给网络,并查看每个图层的输出以及为输入设置训练神经网络的类.我认为在每个图层的图像和权重向量上做点积可能很容易,但它根本不起作用.
我有每个图层的对象:
# Reshape matrix of rasterized images of shape (batch_size, 28 * 28)
# to a 4D tensor, compatible with our LeNetConvPoolLayer
# (28, 28) is the size of MNIST images.
layer0_input = x.reshape((batch_size, 1, 28, 28))
# Construct the first convolutional pooling layer:
# filtering reduces the image size to (28-5+1 , 28-5+1) = (24, 24)
# maxpooling reduces this further to (24/2, 24/2) = (12, 12)
# 4D output tensor is thus of shape (batch_size, …Run Code Online (Sandbox Code Playgroud) 我正在开发一个Spring Boot Web应用程序。问题出在登录方案中。假设我有一个用用户名“ Ali”注册的用户。该用户可以使用用户名“ Ali”或“ ali”登录。下面的代码代表了我的spring安全配置类。似乎在比较时,Spring Boot不会检查大写小写因子,但我希望对其进行检查。

我正在使用gulp来复制和清理我的前端项目.我想运行一些顺序任务.这意味着,例如,我希望启动并完成复制任务,然后运行以下任务(复制任务).我在运行任务时经常看到这个错误:
events.js:72
throw er; // Unhandled 'error' event

Error: ENOENT, lstat '/home/reza/projects/account-web/dist/views'

之后lstat,我每个人都会随机看到一个文件名.我只是发现当没有dist文件夹或者它是空的复制任务正常运行但是当dist文件夹不为空时甚至干净的任务抛出和错误.我的gulp文件和命令结果如下:

@Component({
selector: 'my-app',
templateUrl: './app.component.html',
styleUrls: [ './app.component.css' ]
})
export class AppComponent {
name = 'Reactive Form';
changedValue;
oldValue;
ooldValue;
rform = new FormGroup({
inputOne: new FormControl('chang me')
});
onOneChange(event) {
this.changedValue = event.target.value;
console.log('oneChanged', this.changedValue, 'old value is', this.oldValue);
this.ooldValue = this.oldValue;
setTimeout( ()=>this.oldValue = this.changedValue, 1);
}

</form>

正如您所看到的,它已通过在代码中保留三个变量来解决,这是不可取的(是的,changedValue可以删除该变量,但仍然有两个变量保留旧值很烦人,不是吗?)。
有没有办法用更少的变量重写代码?Angular 本身有下降的方式来做到这一点吗?

我将在c中有一个数组数组,因为主数组中的每个数组都有一个特定的大小.例如:{{a,b,c},{a},{a,d}}问题是我不想使用堆内存并使用"malloc",它也不应该是任何浪费的内存.例如,我不想使用以下代码:
char myArrays[][3] = {
{a,b,c},
{a,null,null},
{a,d,null}
