Speed Up Model Training with torch.compile & Grad Accumulation
Read Full Article: Speed Up Model Training with torch.compile & Grad Accumulation
Training deep transformer language models can be accelerated using two main techniques: torch.compile() and gradient accumulation. With the introduction of PyTorch 2.0, torch.compile() allows for the compilation of models, optimizing them for better performance by creating a computation graph. This compiled model shares the same tensors as the original model, but it is crucial to ensure the model is error-free before compiling, as debugging becomes more challenging. Gradient accumulation, on the other hand, is a method to simulate a larger batch size by accumulating gradients over multiple forward passes, reducing the number of backward passes and optimizer updates needed. This approach is particularly useful in memory-constrained environments, as it allows for efficient training without requiring additional memory. Adjustments to the learning rate schedule are necessary when using gradient accumulation to ensure proper training dynamics. These techniques are important for improving the efficiency and speed of training large models, which can be a significant bottleneck in machine learning workflows.

Training a Model for Code Edit Predictions
Read Full Article: Training a Model for Code Edit Predictions
Developing a coding agent like NES, designed to predict the next change needed in a code file, is a complex task that requires understanding how developers write and edit code. The model considers the entire file and recent edit history to predict where and what the next change should be. Capturing real developer intent is challenging due to the messy nature of real commits, which often include unrelated changes and skip incremental steps. To train the edit model effectively, special edit tokens were used to define editable regions, cursor positions, and intended edits, allowing the model to predict the next code edit within a specified region. Data sources like CommitPackFT and Zeta were utilized, and the dataset was normalized into a unified format with filtering to remove non-sequential edits. The choice of base model for fine-tuning was crucial, with Gemini 2.5 Flash Lite selected for its ease of use and operational efficiency. This managed model avoids the overhead of running an open-source model and uses LoRA for lightweight fine-tuning, ensuring the model remains stable and cost-effective.
