Dr. James McCaffrey of Microsoft Research kicks off a series of four articles that present a complete end-to-end production-quality example of binary classification using a PyTorch neural network, including a full Python code sample and data files. # shape from (2000, 28, 28) to (2000, 1, 28, 28), value in range(0, 1) 45 test_y = test_data.test_labels[: 2000] 46 47 48 class CNN(nn.Module): 49 def __init__(self): 50 super(CNN, self).__init__() 51 self.conv1 = nn.Sequential( # input shape (1, 28, 28) 52 nn.Conv2d( 53 in_channels= 1, # input height 54 out_channels= 16, # n_filters 55 kernel ... zumba fitness dance video download -8Ls
