MATLAB深度学习：自定义CNN网络定义中的错误

Question

我想使用Matlab深度学习工具箱创建自定义CNN网络，但显示以下错误。图层定义良好，但是net = layerGraph(layers);命令显示错误。

Gr=128; Gt=32;
vecInput = imageInputLayer([Gr,Gt,3], 'Name', 'input');
Conv2d1 = convolution2dLayer(3,16,'Padding','same'); %size: 128*32*16
BN1 = batchNormalizationLayer('Name','BN1');
relu1 = reluLayer('Name','relu1');
pool1 = averagePooling2dLayer(2,'Stride',2,'Name','pool1'); %size: 64*16*16
Conv2d2 = convolution2dLayer(3,32,'Padding','same'); %size: 64*16*32
BN2 = batchNormalizationLayer('Name','BN2');
relu2 = reluLayer('Name','relu2');
pool2 = averagePooling2dLayer(3,'Stride',2,'Name','pool2'); %size: 32*8*32
Conv2d3 = convolution2dLayer(3,2,'Padding','same'); %size: 32*8*2
BN3 = batchNormalizationLayer('Name','BN2');
relu3 = reluLayer('Name','relu3');
fc1 = fullyConnectedLayer(1024,'Name','fc1');
relu4 = reluLayer('Name','relu4');
fc2 = fullyConnectedLayer(4096,'Name','fc2');
relu5 = reluLayer('Name','relu5');
reglayer = regressionLayer('Name','output');
layers = [
            vecInput
            Conv2d1
            BN1
            relu1
            pool1
            Conv2d2
            BN2
            relu2
            pool2
            Conv2d3
            BN3
            relu3
            fc1
            relu4
            fc2
            relu5
            reglayer];
        
net = layerGraph(layers); %This command is showing error

错误消息：
