基本构件

构件类型

基本构件类型和顺序是：

\pic, 表示添加层
指定层的位置： \pic[shift ={(x, y, z)}] at (x, y, z)，表示：第1个坐标是指相对于第2个坐标的偏移量
添加具体类型的层，其中，**Box={…}**表示单个层， **RightBandedBox={…}**表示多个层，**Ball={…}**表示层间相加符号 $encoding="application/x-tex">\bigoplus</annotation></semantics></math>$
添加层间连线，\draw [connection] (层的位置，如vonv1-east,或坐标(x,y,z)) – node { 箭头形状，如\midarrow} (cr2-west)
自定义层间连线路径，**\path (p4-east) – (cr5-west) coordinate[pos=0.25] (between4_5) **

层的类型

网络中层包括：layer, block 和 unit。

在绘制网络层时，要在指定层的类型

其中，layer是单个网络层，对应的配置文件是layers文件夹下的Box.sty，在绘图时，所用的命令是：

{Box                ={
           name    =...,
           caption =  ...,
           xlabel  = ...,
           ylabel  = ...,
           fill    = ...,
           opacity = ...,
           height  = ...,width= ...,depth= ...,
                   }
   }

其中，以下语句是绘图时常用的，其中，\subimport{…/layers/}{init}，表示layer文件夹下的init文件，因此，这一句的具体写法要结合当前tex文件所在位置。**\def\ReLUColor{rgb:red,1;black,0.3}**是自定义的ReLU层的颜色，可以根据需要自己调整。

\documentclass[border=15pt, multi, tikz]{standalone}
\usepackage{import}
\subimport{../layers/}{init}
\usetikzlibrary{positioning}
\usetikzlibrary{3d} %for including external image 

\def\ReLUColor{rgb:red,1;black,0.3}

\begin{document}
\begin{tikzpicture}
\tikzstyle{connection}=[ultra thick,every node/.style={sloped,allow upside down},draw=\edgecolor,opacity=0.7]

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% 这部分添加绘图命令
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\end{tikzpicture}
\end{document}

可以看到，图中标签“深度”的位置没有居中，需要自行设置，具体设置方法见下文自定义配置。

单个layer

单个layer要在shift后指定Box，可以通过fill指定填充的颜色，height=..,width=...,depth=...指定图片的高、宽和深。

[shift ={(0,0,0)}] at (0,0,0)表示第1个坐标是指相对于第2个坐标的偏移量。
name =score16,% 表示该层的名称
caption= 标题, %表示该层的标题
xlabel ={{ "宽度：显示的是s\_filer的值", }}, 无论是中文还是英文，只能显示第1个位置的字符;同时，要在s后加转义符\：s\_filer。xlabel的值是数组形式，即(x,y,z,…),在Box中只显示第1个值,即x。如果是在"RightBandedBox",则可以显示多个值。
ylabel ={{高度 }}, 加不加引号，似无影响；这里可以显示多个字符;ylabel在神经网络架构中一般不显示
zlabel = 深度, ：显示的是n_filer的值, 加不加{}，似无影响；这里可以显示多个字符
opacity表示透明度

% one layer for a conv or BN or ReLU layer, etc
\pic[shift         ={(5,0,0)}] at  (0,0,0) % 第1个坐标是指相对于第2个坐标的偏移量
    {
        Box        ={
            name   =conv,% 表示该层的名称 
            caption= 标题, %表示该层的标题
            xlabel ={{ "宽度： 显示的是s\_filer的值",  }}, % 无论是中文还是英文，只能显示第1个位置的字符;同时，要在s后加转义符\
            ylabel ={{高度 }}, % 加不加引号，似无影响；这里可以显示多个字符;ylabel在神经网络架构中一般不显示
            zlabel = 深度： 显示的是n\_filer的值, % 加不加{}，似无影响；这里可以显示多个字符
            fill   =\ReLUColor,
            opacity = 0.2,
            height=64,width=30,depth=45
                    }
    };

效果如图所示：

layer组合

多个layer的组合，有2种方法实现。

在shift后使用RightBandedBox，此外，layer的名称和层数，是通过xlabel和width进行设定。例如：xlabel={{"32","64", "128"}}， ···，width={2,2,4}。xlabel和width的值是数组形式，即(x,y,z,…)，数组内的数值个数决定了有多少个层。
通过多个Box，使多个单层layer成为layers的组合。

例如：

\pic[shift={(5,0,0)}] at (0,0,0) 
    {RightBandedBox={
            name=cr1,
            caption=使用RightBandedBox,
            xlabel={{"1","2", "3"}},
            % zlabel=layer_blocks,
            fill=\ConvColor,
            bandfill=\ConvReluColor,%
            opacity = 0.2,
            height=40,width={1,1,1},depth=40}
    };

% conv+bn+relu
\pic[shift          ={    (10,0,0)}] at  (0,0,0) 
    {
    Box             ={
        name        =conv1,%
        xlabel      ={{1}},
        fill        =\ConvColor,%
        height      =40,width=1,depth=40}
    };
\pic[shift          ={ (0,0,0)}] at (conv1-east) 
    {
        Box         ={
        name        =bn1,%
        caption     =layer叠加,
        xlabel      ={{2}},
        fill        =\BnColor,%
        opacity     =0.5,
        height      =40,width=1,depth=40}
    };
\pic[shift          ={(0,0,0)}] at (bn1-east)
    {
            Box     ={
            name    =relu1,%
            xlabel  ={{3}},
            fill    =\ReLUColor,
            opacity =0.5,
            height  =40,width=1,depth=40,
             }
    };

PlotNeuralNet的个性化定制

PlotNeuralNet默认将图形的深度，也就是n_fliter的数据标注在角上，如下图所示，没有居中，因此，需要对它进行修改。

自定义方法：修改layers文件夹下的Box.sty和RightBandedBox.sty文件。

zlabel zlabel

Box.sty

将depthlabel设置中的pos=0改为pos=0.5，将captionlabel中的文本宽度由text width=15改为text width=40，这是因为默认宽度有些小，长文本显示不全。

\coordinate (a1) at (0 , \y/2 , \z/2);
\coordinate (b1) at (0 ,-\y/2 , \z/2);
~~\tikzstyle{depthlabel}=[pos=0,text width=14*\z,text centered,sloped]~~
\tikzstyle{depthlabel}=[pos=0.5,text width=14*\z,text centered,sloped]

~~\tikzstyle{captionlabel}=[text width=15*\LastEastx/\scale,text centered]~~
\tikzstyle{captionlabel}=[text width=40*\LastEastx/\scale,text centered]

\path (\LastEastx/2,-\y/2,+\z/2) + (0,-25pt) coordinate (cap)
edge ["\textcolor{black}{ \bf \caption}"',captionlabel](cap) ; %Block caption/pic object label

RightBandedBox.sty

RightBandedBox.sty的修改与Box.sty的修改类似。pos=0改为pos=0.5，text width=15改为text width=40

\path (c) edge ["\small\zlabels"',depthlabel](f); %depth label'\path (b1) edge ["\ylabel",midway] (a1); %height label’

~~\tikzstyle{captionlabel}=[text width=15*\LastEastx/\scale,text centered]~~
`\tikzstyle{captionlabel}=[text width=40*\LastEastx/\scale,text centered]’

\path (\LastEastx/2,-\y/2,+\z/2) + (0,-25pt) coordinate (cap)'edge ["\textcolor{black}{ \bf \caption}"’,captionlabel] (cap); %Block caption/pic object label’
