Reference implementation of operators for deep signal processing architectures

Vortex

This repository contains implementations of computational primitives for convolutional multi-hybrid models and layers: Hyena-[SE, MR, LI], StripedHyena 2, Evo 2.

For training, please refer to the savanna project.

Interface

There are two main ways to interface with vortex:

1. Use vortex as the inference engine for pre-trained multi-hybrids such as Evo 2 40B. In this case, we recommend installing vortex in a new environment (see below).
2. Import from vortex specific classes, kernels or utilities to work with custom convolutional multi-hybrids. For example,sourcing utilities from hyena_ops.interface.

1. Pip install (easiest)

The simplest way to install vortex is from PyPi. This requires you to have dependencies already installed.

pip install vtx

or you can install Vortex after cloning the repository:

pip install .

Note this will take a few minutes to compile, which can be sped up by being on more CPUs.

2. Quick install for vortex ops

make setup-vortex-ops

Note that this does not install all dependencies required to run autoregressive inference with larger pre-trained models.

3. Building a custom development environment

Using conda, venv or uv

To run e2e installation in a uv environment, use the following command:

make setup-full

Note that the setup-full step will compile various CUDA kernels, which usually takes at most several minutes. It may be necessary to customize CUDA header and library paths in Makefile.

4. Running in a Docker environment

Docker is one of the easiest ways to get started with Vortex (and Evo 2). The Docker environment does not depend on the currently installed CUDA version and ensures that major dependencies (such as PyTorch and Transformer Engine) are pinned to specific versions, which is beneficial for reproducibility.

To run Evo 2 40B generation sample, simply run ./run.

To run Evo 2 7B generation sample: sz=7 ./run.

To run tests: ./run ./run_tests.

To interactively execute commands in docker environment: ./run bash.

Generation quickstart

python3 generate.py \
    --config_path <PATH_TO_CONFIG> \
    --checkpoint_path <PATH_TO_CHECKPOINT> \
    --input_file <PATH_TO_INPUT_FILE> \
    --cached_generation

--cached_generation activates KV-caching and custom caching for different variants of Hyena layers, reducing peak memory usage and latency.
