Error using DAGNetwork/calculatePredict>predictBatch (line 151)
Incorrect input size. The input images must have a size of [227 227 3].
Error in DAGNetwork/calculatePredict (line 17)
Y = predictBatch( ...
Error in DAGNetwork/classify (line 134)
scores = this.calculatePredict( ...

Hi,
The issue might be due input image resolution. alexnet expects an input of size 227*227*3. The image you are passing may not be of the same size. Try resizing the image using imresize function to 227*227*3.
Hope this helps
