To add support for FAISS in your Python project, you need to follow these general steps:
Install FAISS:
pip install faiss-cpu # for CPU version
For GPU support, you can install faiss-gpu
. Make sure you have the necessary dependencies installed for GPU support.
Import FAISS in Your Python Script:
import faiss
Use FAISS Functionality:
# Assuming you have a set of vectors 'x' and a query vector 'q'
index = faiss.IndexFlatL2(x.shape[1]) # L2 distance index
index.add(x)
D, I = index.search(q, k=5) # Search for the 5 nearest neighbors
Integrate FAISS into Your Project:
Test and Optimize:
Handle Dependencies and Versions:
Here's a very basic example using FAISS for similarity search:
import faiss
import numpy as np
# Generate some random data for demonstration purposes
d = 64 # dimension
nb = 100000 # number of vectors
np.random.seed(123)
xb = np.random.random((nb, d)).astype('float32')
# Build the FAISS index
index = faiss.IndexFlatL2(d)
index.add(xb)
# Query for the nearest neighbors
k = 5
xq = np.random.random((1, d)).astype('float32')
D, I = index.search(xq, k)
print("Query vector:")
print(xq)
print("\nNearest neighbors:")
print(xb[I[0]])
print("\nDistances:")
print(D[0])
Remember to adapt these steps to your specific project structure and requirements.
@eavanvalkenburg would this be something we can work on after your new memory changes go in?
