Embedding only works on the first GPU #2974
Comments
Hi, I'm not able to reproduce this: import torch
sentence_transformers import SentenceTransformer
device = torch.device('cuda:0')
model=SentenceTransformer('bert-base-cased').to(device)
testdata=['example','text','to','test','if','embedding','works']
embeddings=model.encode(sentences=testdata, device=device, convert_to_tensor=True)
print(embeddings)
tensor([[ 3.5326e-01, 1.2674e-01, -1.1257e-01, ..., 1.8065e-01,
4.4132e-01, 4.3305e-01],

4.1688e-01, 2.8164e-01]], device='cuda:0') Running this on my other GPU gives this result: device=torch.device('cuda:1')
model=SentenceTransformer('bert-base-cased').to(device)
testdata=['example','text','to','test','if','embedding','works']
embeddings=model.encode(sentences=testdata, device=device, convert_to_tensor=True)
print(embeddings)

Using the latest transformers and sentence-transformers, on a multi-gpu system.
When I try to run this, the results are correct:
device=torch.device('cuda:0')
model=SentenceTransformer('danieleff/hubert-base-cc-sentence-transformer').to(dev)
testdata=['example','text','to','test','if','embedding','works']
embeddings=model.encode(sentences=testdata,device=device,convert_to_tensor=True)
print(embeddings)
tensor([[-0.0453, 0.0019, 0.1803, ..., 0.1711, 0.9855, 0.2834],
[-0.0889, -0.1105, -0.4963, ..., 0.0567, 0.8881, 0.5029],
[ 0.4389, -0.1606, 0.2297, ..., -0.1548, 0.1970, 0.5715],
...,
[ 0.4820, -0.7396, 0.2189, ..., 0.0417, 0.9316, 0.5099],
[ 0.3530, 1.0408, -0.4530, ..., -0.3674, 0.2982, 0.0062],
[-0.0248, -0.1467, -0.0671, ..., -0.3485, 0.7563, 0.5532]],
device='cuda:0')
But if I try to run this code, which only differs in the target device:
device=torch.device('cuda:0')
model=SentenceTransformer('danieleff/hubert-base-cc-sentence-transformer').to(dev)
testdata=['example','text','to','test','if','embedding','works']
embeddings=model.encode(sentences=testdata,device=device,convert_to_tensor=True)
print(embeddings)
The results are:
tensor([[0., 0., 0., ..., 0., 0., 0.],
[0., 0., 0., ..., 0., 0., 0.],
[0., 0., 0., ..., 0., 0., 0.],
...,
[0., 0., 0., ..., 0., 0., 0.],
[0., 0., 0., ..., 0., 0., 0.],
[0., 0., 0., ..., 0., 0., 0.]], device='cuda:3')
Is it possible to use SentenceTransformer on GPU other than cuda:0?
