About

This repository contains boilerplate for PyTorch's training loop.

Some features included in this boilerplater are:

1. Periodic Checkpoints

• Automatically save checkpoints of model state, optimizer state and training scores every x epochs
• Load checkpoints

2. Gradient Scaling

• If the gradients are computed as float16, the value of gradients may underflow to 0.
• Gradients are scaled up after backpropagation and scaled down before optimizer step to solve this

3. Automatic Tensor Casting

• The outputs and loss of the model are lowered in precision for less memory usage.

4. Garbage Collection

• Every batch, the cache is cleared and non-used objects are flushed from memory.
