Evo2 Dataset
Dataset Description
Evo2 Dataset is an Evo2 mini genome dataset adapted for OneScience/evo2/. It contains FASTA, compressed FASTA, and merged FASTA files for human chr20, chr21, and chr22, as well as train, validation, and test .bin/.idx splits preprocessed with the Byte-Level tokenizer.
Supported Tasks
This dataset is not the complete OpenGenome2 dataset and is not intended to reproduce full-scale pretraining. It is intended for preflight checks of the standard Evo2 model repository, FASTA prediction input, and smoke tests for mini training or fine-tuning.
Dataset Format and Structure
| Data | Format | Description |
|---|---|---|
| Raw sequences | FASTA / gzip FASTA | chr20, chr21, chr22, and merged FASTA |
| Preprocessed training split | .bin + .idx |
chr20_21_22_uint8_distinct_byte-level_train |
| Preprocessed validation split | .bin + .idx |
chr20_21_22_uint8_distinct_byte-level_val |
| Preprocessed test split | .bin + .idx |
chr20_21_22_uint8_distinct_byte-level_test |
| Checksum manifest | TSV / SHA256 | File names, sizes, and hashes |
The default location within the dataset package is data_mini/genome_data/.
How to Use the Dataset
Files and Download
Download the dataset:
hf download --dataset OneScience-Group/evo2_dataset
Model weights must be downloaded separately to validate the model:
hf download --model OneScience-Group/evo2/
Data Placement and Validation
Default model data path:
<MODEL_REPO_ROOT>/data/evo2_dataset/data_mini/genome_data/
Place data_mini in the model package:
mkdir -p <MODEL_REPO_ROOT>/data/evo2_dataset
cp -a data_mini <MODEL_REPO_ROOT>/data/evo2_dataset/data_mini
Validation command:
python scripts/validate_evo2_dataset.py --package-root . --dataset-root data_mini
For a quick structure-only check, add --skip-sha256.
