I tried replicating the MNIST example from Lession 4 with the DataBlock API. I have two problems:
- The learner takes much longer to train (minutes instead of seconds)
- The learner does not learn (the accuracy stays around 0.5)
Can someone of you look at it and point out what I am doing wrong. I have a hard time finding the error:
