![]() The python and Matlab versions are identical in layout to the CIFAR-10, so I won't waste space describing them here. Yes, I know mushrooms aren't really fruit or vegetables and bears aren't really carnivores.ĬIFAR-100 binary version (suitable for C programs) Lawn-mower, rocket, streetcar, tank, tractor Orchids, poppies, roses, sunflowers, tulipsĪpples, mushrooms, oranges, pears, sweet peppersĬlock, computer keyboard, lamp, telephone, televisionīee, beetle, butterfly, caterpillar, cockroachĬamel, cattle, chimpanzee, elephant, kangarooĬrocodile, dinosaur, lizard, snake, turtleīicycle, bus, motorcycle, pickup truck, train Here is the list of classes in the CIFAR-100: SuperclassĪquarium fish, flatfish, ray, shark, trout Each image comes with a "fine" label (the class to which it belongs) and a "coarse" label (the superclass to which it belongs). The 100 classes in the CIFAR-100 are grouped into 20 superclasses. There are 500 training images and 100 testing images per class. ![]() This dataset is just like the CIFAR-10, except it has 100 classes containing 600 images each. The class name on row i corresponds to numeric label i. It is merely a list of the 10 class names, one per row. This is an ASCII file that maps numeric labels in the range 0-9 to meaningful class names. Therefore each file should be exactly 30730000 bytes long. The values are stored in row-major order, so the first 32 bytes are the red channel values of the first row of the image.Įach file contains 10000 such 3073-byte "rows" of images, although there is nothing delimiting the rows. The first 1024 bytes are the red channel values, the next 1024 the green, and the final 1024 the blue. The next 3072 bytes are the values of the pixels of the image. In other words, the first byte is the label of the first image, which is a number in the range 0-9. See also hdf5storage, which can indeed be used for saving.It's a bit more difficult than expected, so it's not on the roadmap for now For now, you can't save anything back to the.If someone tells me how to convert them, I'll implement that Proprietary MATLAB types (e.g datetime, duriation, etc) are not supported.This library will only load mat 7.3 files.The following MATLAB datatypes can be loaded MATLAB loadmat ( 'data.mat', only_include = ) tree1 = data_dict # the entire tree has been loaded, so tree1 is a dict with all subvars of tree1 subsubvar = data_dict # this subvar has been loaded InstallationĪlternatively for most recent version: pip install git+ loadmat ( 'data.mat', only_include = 'structure' ) struct = data_dict # now only structure is loaded and nothing else data_dict = mat73. You can also specifiy to only load a specific variable or variable tree, useful to reduce loading times data_dict = mat73. loadmat ( 'data.mat', use_attrdict = True ) struct = data_dict # assuming a structure was saved in the. loadmat ( 'data.mat' )īy enabling use_attrdict=True you can even access sub-entries of structs as attributes, just like in MATLAB: data_dict = mat73. This library loads MATLAB 7.3 HDF5 files into a Python dictionary. NotImplementedError : Please use HDF reader for matlab v7. This means they cannot be loaded by scipy.io.loadmat any longer and raise. mat files have been changed to store as custom hdf5 files.
