in pool1_2, input size mismatch. size of input to this layer is different from the expected input size. Inputs to this layer: from the layer relu1_2 (1*1*64 output)
If I call analyzeNetwork(layers), I see that on layer 28, pool1_2, you are trying to do a 2x2 max pooling operation, but the act...

Invalid training data. The output size (1000) of the last layer does not match the number of classes (5).
As in Yanqi Liu's comment, you probably need to modify the fully connected layer too: fullyConnectedLayer(5,"Name","fc","BiasLe...
