Code Example (Python - Snowpark ML for Linear Regression):

from snowflake.snowpark import Session
from snowflake.snowpark.functions import col
from snowflake.ml.modeling.linear_model import LinearRegression
from snowflake.ml.modeling.metrics import mean_squared_error
import json

# Create Snowpark session (assuming connection details are in config.json)
with open('config.json') as f:
    connection_parameters = json.load(f)
session = Session.builder.configs(connection_parameters).create()

# Load data into a Snowpark DataFrame
snowpark_df = session.table("YOUR_DATABASE.YOUR_SCHEMA.YOUR_TABLE")

# Prepare features and target
features = ["FEATURE1", "FEATURE2", "FEATURE3"]
target = "TARGET_COLUMN"

# Initialize and train a Linear Regression model
lr = LinearRegression(input_cols=features, output_cols=["PREDICTION"], label_cols=[target])
lr.fit(snowpark_df)

# Make predictions
predictions_df = lr.predict(snowpark_df)
predictions_df.show()

# Evaluate (example)
mse = mean_squared_error(df=predictions_df, y_true_col_names=[target], y_pred_col_names=["PREDICTION"])
print(f"Mean Squared Error: {mse}")

session.close()

import torch
import torch.nn as nn
import torch.optim as optim
from torchvision import datasets, transforms

# 1. Start a new W&B run
wandb.init(project="mnist-pytorch-example", config={
    "learning_rate": 0.01,
    "epochs": 5,
    "batch_size": 64,
    "architecture": "CNN",
    "dataset": "MNIST"
})
config = wandb.config

# 2. Define a simple CNN model
class Net(nn.Module):
    def __init__(self):
        super(Net, self).__init__()
        self.conv1 = nn.Conv2d(1, 10, kernel_size=5)
        self.relu = nn.ReLU()
        self.fc = nn.Linear(10 * 12 * 12, 10)

    def forward(self, x):
        x = self.relu(self.conv1(x))
        x = nn.MaxPool2d(2)(x)
        x = x.view(-1, 10 * 12 * 12)
        x = self.fc(x)
        return x

# 3. Load data
transform = transforms.Compose([
    transforms.ToTensor(),
    transforms.Normalize((0.1307,), (0.3081,))
])
train_loader = torch.utils.data.DataLoader(
    datasets.MNIST('../data', train=True, download=True, transform=transform),
    batch_size=config.batch_size, shuffle=True
)

# 4. Train the model
model = Net()
optimizer = optim.Adam(model.parameters(), lr=config.learning_rate)
criterion = nn.CrossEntropyLoss()

for epoch in range(config.epochs):
    for batch_idx, (data, target) in enumerate(train_loader):
        optimizer.zero_grad()
        output = model(data)
        loss = criterion(output, target)
        loss.backward()
        optimizer.step()

        # 5. Log metrics to W&B
        wandb.log({"loss": loss.item()})

    print(f"Epoch {epoch+1}, Loss: {loss.item()}")

# 6. Log the final model
