To use Evo2 easily in HPC

EasyEvo2

A Python toolkit for easily using Evo2 models in bioinformatics workflows, particularly in HPC environments.

Description

EasyEvo2 provides a simplified interface to Evo2 foundation models for sequence embedding. It enables biologists and bioinformaticians to efficiently extract embeddings from DNA, RNA, or protein sequences without extensive deep learning expertise. It's specially designed to work well in High-Performance Computing (HPC) environments.

Installation

# Install from PyPI
pip install easyevo2

# Or install from source
git clone https://github.com/ylab-hi/EasyEvo2.git
cd EasyEvo2
pip install .

Usage

Basic Usage

# Embed sequences from a FASTA/FASTQ file using the default model (evo2_7b)
easyevo2 embed input.fa

# Specify a different model and specific layer
easyevo2 embed input.fa --model-type evo2_40b --layer-name blocks.28.mlp.l3

# Specify a different model and multiple layers
easyevo2 embed input.fa --model-type evo2_40b --layer-name blocks.28.mlp.l3 blocks.28.mlp.l2

# Save to a specific output file
easyevo2 embed input.fa --output my_embeddings

The output will be a safetensor file containing the embeddings for each sequence in the input file. We can load the embeddings using the load_tensor function:

from easyevo2 import load_tensor

embeddings = load_tensor("my_embeddings.mode.layer.safetensors")
print(embeddings)
# Output: {
# "seq1": torch.tensor([...]),
# "seq2": torch.tensor([...]),
# }
