&gt;Of course, the right choice is always to know what you&#x27;re doing and never to make any mistakes. This may involve sketching your network architecture out on paper, doing a masters in machine learning, or getting someone else do either one of those for you and going to the beach instead. If you are a fallible human being, though, or you&#x27;ve blown through your vacation budget already, I hope these nuggets of intermittently sound advice help you iterate faster and (eventually) get your bleeping convnet to work.<p>Or you could do a master&#x27;s in computer science.<p>Grad school is not trade school
