2 years ago On Putting Multiple Print Statements I was able to single out the error:
I ran out this code:
import faiss
import numpy as np
d = 64 # dimension
nb = 100000 # database size
nq = 10000 # nb of queries
np.random.seed(1234) # make reproducible
xb = np.random.random((nb, d)).astype('float32')
xb[:, 0] += np.arange(nb) / 1000.
xq = np.random.random((nq, d)).astype('float32')
xq[:, 0] += np.arange(nq) / 1000.
index = faiss.IndexFlatL2(d) # build the index
print(index.is_trained)
index.add(xb) # add vectors to the index
print(index.ntotal)
print("Done")
k = 4 # we want to see 4 nearest neighbors
D, I = index.search(xb[:5], k) # sanity check
print("Done???")
print(I)
print(D)
D, I = index.search(xq, k) # actual search
print(I[:5]) # neighbors of the 5 first queries
print(I[-5:]) # neighbors of the 5 last queriesThe Second Done Statement doesn't get printed and there is a Segmentation Fault Error so it fails on searching.
