Optimizer step

- If your model doesn't fit into memory with a large batch size, you can use gradient accumulation. This involves accumulating gradients over multiple small batches before performing an update. ```python def train_model(model, opti…

Ensure that your model maintains high stability by using techniques such as gradient clipping, dropout, and proper initialization. ```python def train_model(model, train_loader, val_loader, epochs=10, lr=0.001): criterion = nn.MSELoss(…

3. **Calculate Latency**: Compute the latency by subtracting the start time from the end time. 4. **Log Latency**: Use Python's logging module to log the latency for each query. ### Example Implementation Here's an example implementation …
