In this notebook I am using the Cifar10 dataset to classify various images. on CIFAR-10 dataset Any model listed in the code can be trained just by initiating the model function to the declared variable 'net' Model Accuracy LeNet 73.53 VGG16 91.47 GoogLeNet 92.93 DenseNet121 93.51 Then, I prepared the dataset CIFAR10 to be used in this project with the function transforms.Compose, this function will receive a list of steps that will transform the input data. The images are 3x32x32, i.e., 3 channels (red, green, blue) each of size 32x32 pixels. I got the training dataset by assigning the hyper-parameter train True, testing dataset by setting it to False, and both are applied thetransform to the above data pipeline. The network needs to be defined in Sequential and I want to train it on CIFAR10. The CIFAR-10 and CIFAR-100 are labeled subsets of the 80 million tiny images dataset. Can run both on CPU only and GPU. The model got half of the four testing images correct. This function received the predicted y value of n-features and the labels and does the softmax calculation, in my case, I have 10-feature predicted outputs for each image. It looks like your model is still on the CPU. PyTorch provides data loaders for common data sets used in vision applications, such as MNIST, CIFAR-10 and ImageNet through the torchvision package.
