Your log says: "MatConvNet is not compiled. Consider running vl_compilenn" So it sounds like you haven't compiled MatConvNet. Please follow MatConvNet installation instructions: https://www.vlfeat.org/matconvnet/install/ After that, please remove the files created by your previous run as they are likely empty due to the errors, and the code doesn't redo files if they already exist.
