📊 HDF5 Structure
Every HDF5 file follows the standard format:
base:(N_base, Dim)float32 base vectors (L2-normalized).calib:(N_calib, Dim)float32 calibration query vectors.eval:(N_eval, Dim)float32 evaluation query vectors.eval_candidates:(N_eval, 100)int32 exact brute-force top-100 neighbor indices.
🚀 Usage
import h5py
import numpy as np
with h5py.File("colbert-python-128-normalized.hdf5", "r") as f:
base = f["base"][:]
eval_q = f["eval"][:]
gt = f["eval_candidates"][:]
print(f"Base shape: {base.shape}, Eval shape: {eval_q.shape}")
