What does the key " b'batch_label' " in cifar-10 unpickle by python use for?
The cifar10 dataset you are donwloading is splitted in serveral batches.
Each batch has its own id (batch_label).
data is the actual batch if images, while filenames is the name of the images encoded. labels, of course, is the set of labels associated with the data
When I unpickle cifar-10 by python, I get a dictionary with 4 keys:'batch_label','data','filenames','labels'. But I don't konw what the key 'batch_label' represent for. It's a 'bytes' type data, length is 21. I konw I needn't to know it when I train a network. But I'm still curious about it. Thanks for any reply. ^_^
