## About
_xT_ enables you to model large images, end-to-end, on contemporary, memory-limited GPUs. It is a simple framework for vision transformers which effectively aggregates global context with local details.
## Installation
* `conda env create -f environment.yml`
The code has been tested on Linux on NVIDIA A100 GPUs with PyTorch 2+. We use custom CUDA kernels as implemented by the `Mamba` and `OpenAI Triton` projects. Therefore, modifications may be required to use this repository on other operating systems or GPUs.
## Training
Training can be launched through
```./run_submit.sh config=```
We also provide [SubmitIt](https://github.com/facebookincubator/submitit) scripts in `launch_scripts` to submit training jobs on Slurm clusters.
## Pretrained Models
Weights and configs for our experiments are available on [Hugging Face](https://huggingface.co/bair-climate-initiative/swin-xt/tree/main).
