Question about 'index_cpu_to_gpus_list'

[ezeli]

Summary

I have two GPUs: 0 and 1. When I use faiss.index_cpu_to_gpus_list(index, gpus=[1]) to specify GPU 1, GPU 0 is also used. What is the data on GPU 0? How can I only use GPU 1?

Platform

OS: CentOS Linux

Faiss version: 1.7.2

Installed from: pip

Faiss compilation options:

Running on:

• CPU
• GPU

Interface:

• C++
• Python

Reproduction instructions

import faiss
import numpy as np
vectors=np.random.rand(2000000, 312).astype(np.float32)
d = vectors.shape[1]
index = faiss.IndexFlatIP(d)
index = faiss.index_cpu_to_gpus_list(index, gpus=[1])
