Re-build Resnet 50 but error

Hello, any other guys solve this problem ? i was change the some code but tooks error . can u anyother guys solve this problem ?

original code is running

orginal code is here :

inputSize = [256 192 3]; originalNet = resnet18;

lgraph = layerGraph(originalNet); lgraph = removeLayers(lgraph,'pool5');

lgraph = removeLayers(lgraph,'fc1000'); lgraph = removeLayers(lgraph,'prob');

lgraph = removeLayers(lgraph,'ClassificationLayer_predictions');

layers = [

transposedConv2dLayer(4,256,"Name","transposed-conv_1","Cropping","same","Stride",[2 2], "BiasLearnRateFactor", 0)

%batchNormalizationLayer("Name","batchnorm_1")

reluLayer("Name","relu_1")

transposedConv2dLayer(4,256,"Name","transposed-conv_2","Cropping","same","Stride",[2 2],"BiasLearnRateFactor",0)

%batchNormalizationLayer("Name","batchnorm_2")

reluLayer("Name","relu_2")

transposedConv2dLayer(4,256,"Name","transposed-conv_3","Cropping","same","Stride",[2 2],"BiasLearnRateFactor",0)

%batchNormalizationLayer("Name","batchnorm_3")

reluLayer("Name","relu_3")

convolution2dLayer(1,numJoints,"Name","conv2d_final")

];

lgraph = addLayers(lgraph,layers);

lgraph = connectLayers(lgraph,'res5b_relu','transposed-conv_1/in');

dlnet = dlnetwork(lgraph);

i was change the like that :

inputSize = [256 192 3]; originalNet = resnet50;

lgraph = layerGraph(originalNet);

lgraph = removeLayers(lgraph,'avg_pool');

lgraph = removeLayers(lgraph,'fc1000');

lgraph = removeLayers(lgraph,'fc1000_softmax');

lgraph = removeLayers(lgraph,'ClassificationLayer_fc1000');

layers = [

transposedConv2dLayer(4,256,"Name","transposed-conv_1","Cropping","same","Stride",[2 2], "BiasLearnRateFactor", 0)

%batchNormalizationLayer("Name","batchnorm_1")

reluLayer("Name","relu_1")

transposedConv2dLayer(4,256,"Name","transposed-conv_2","Cropping","same","Stride",[2 2],"BiasLearnRateFactor",0)

%batchNormalizationLayer("Name","batchnorm_2")

reluLayer("Name","relu_2")

transposedConv2dLayer(4,256,"Name","transposed-conv_3","Cropping","same","Stride",[2 2],"BiasLearnRateFactor",0)

%batchNormalizationLayer("Name","batchnorm_3")

reluLayer("Name","relu_3")

convolution2dLayer(1,numJoints,"Name","conv2d_final")

];

lgraph = addLayers(lgraph,layers);

lgraph = connectLayers(lgraph,'activation_49_relu','transposed-conv_1/in');

dlnet = dlnetwork(lgraph);

additional code is here

% Convert dlnetwork to SeriesNetwork

if ~doTraining

modelFile = "simplePoseNet";

else

simplePoseNet = layerGraph(dlnet);

simplePoseNet = replaceLayer(simplePoseNet,'data',...

imageInputLayer(inputSize,"Name","data","Normalization","zscore",...

"Mean",simplePoseNet.Layers(1).Mean,...

"StandardDeviation",simplePoseNet.Layers(1).StandardDeviation));

simplePoseNet = addLayers(simplePoseNet,regressionLayer("Name","RegressionLayer_conv15_fwd"));

simplePoseNet = connectLayers(simplePoseNet,'conv2d_final','RegressionLayer_conv15_fwd/in');

simplePoseNet = assembleNetwork(simplePoseNet);

SkeletonConnectionMap = skeleton;

save("simplePoseNet_"+postfix+"_final",'simplePoseNet','SkeletonConnectionMap');

modelFile = "simplePoseNet_"+postfix+"_final";

end

Hi,

The error is because the size of Mean array argument in imageInputLayer is not correct. Since you have changed the inputSize, the size of Mean array also needed to be changed.

The valid Mean array size are 256x192x3 array or 1x1x3 array of means per channel.

For the more information refer to properties section in imageInputLayer documentation.

Hope it helps!
