adam-atan2 0.0.2

Adam-atan2 Fused Optimizer

Adam-atan2 Fused Operator

Usage

Drop-in replacement of torch.optim.AdamW.

• Doesn't support foreach, fused argument, as the optimizer is already fused
• Doesn't support amsgrad, maximize, capturable, differentiable argument yet

pip install adam-atan2

from adam_atan2 import AdamATan2

# All supported arguments are listed below
optim = AdamATan2(model.parameters(),
    lr=1e-3,
    weight_decay=0.1,
    betas=(0.9, 0.95)
)

Consistency Tests

We tested the consistency against reference AdamW-atan2 PyTorch implementation. To run tests, clone this repository, run pytest:

pip install -e .
pytest
