Neuronetwork Class
Neuronetwork Class is a powerful tool for training, testing, deploying and inferencing deep learning models. It provides a high-level API to build and train various types of neural networks, including feedforward networks, convolutional neural networks (CNNs), and recurrent neural networks (RNNs). With its flexible architecture and extensive capabilities, Neuronetwork Class enables developers to efficiently experiment with different models, optimize hyperparameters, and iterate on their deep learning pipelines.
Usage
-
Import the necessary modules:
import torch import torchvision import torchvision.transforms as transforms
-
Define the hyperparameters and constants:
INPUT_SIZE = 784 HIDDEN_SIZE = 100 NUM_EPOCHS = 5 BATCH_SIZE = 100 LEARNING_RATE = 0.001
-
Load and preprocess the dataset:
train_dataset = torchvision.datasets.MNIST(root='./data', train=True, transform=transforms.ToTensor(), download=True) train_loader = torch.utils.data.DataLoader(dataset=train_dataset, batch_size=BATCH_SIZE, shuffle=True) train_loader = torch.utils.data.DataLoader(dataset=train_dataset, batch_size=BATCH_SIZE, shuffle=True) test_loader = torch.utils.data.DataLoader(dataset=test_dataset, batch_size=BATCH_SIZE, shuffle=False)
-
Define the neural network architecture:
class NeuralNetwork(torch.nn.Module): def __init__(self, input_size, hidden_size, num_classes): super(NeuralNetwork, self).__init__() self.fc1 = torch.nn.Linear(input_size, hidden_size) self.relu = torch.nn.ReLU() self.fc2 = torch.nn.Linear(hidden_size, num_classes) def forward(self, x): out = self.fc1(x) out = self.relu(out) out = self.fc2(out) return out
-
Instantiate the model and move it to the available device:
model = NeuralNetwork(INPUT_SIZE, HIDDEN_SIZE, num_classes=torch.max(train_dataset.targets).item() + 1) device = torch.device('cuda' if torch.cuda.is_available() else 'cpu') model.to(device)
-
Set up the loss function and optimizer:
criterion = torch.nn.CrossEntropyLoss() optimizer = torch.optim.Adam(model.parameters(), lr=LEARNING_RATE)
-
Train the model:
for epoch in range(NUM_EPOCHS): for i, (images, labels) in enumerate(train_loader): images = images.reshape(-1, INPUT_SIZE).to(device) labels = labels.to(device) # Forward pass outputs = model(images) loss = criterion(outputs, labels) # Backward and optimize optimizer.zero_grad() loss.backward() optimizer.step() if (i+1) % 100 == 0: print('Epoch [{}/{}], Step [{}/{}], Loss: {:.4f}' .format(epoch+1, NUM_EPOCHS, i+1, len(train_loader), loss.item()))
-
Evaluate the model:
correct = 0 total = 0
with torch.no_grad():
for images, labels in test_loader:
images = images.reshape(-1, INPUTSIZE).to(device)
labels = labels.to(device)
outputs = model(images)
predicted = torch.max(outputs, dim=1)
total += labels.size(0)
correct += (predicted == labels).sum()
print(‘Test Accuracy of the model on the 10000 test images: {} %’.format(100 * correct / total))
9. Save the trained model:
```python
torch.save(model.state_dict(), "./model/Mnist.pkl")
