Is there GPU support for box-prompted SAM? about efficientsam HOT 7 OPEN

It seems that efficientSAM provided only works on CPU, I tried to use cuda() to move model and data to GPU , but it doesn't help a lot.

Also tried the seg-everything to cuda method in pull requests, doesn't help a lot as well.

Maybe the box-promted SAM needs a function like " predictor.set_image() " in SAM and Mobile-SAM to save time used in a same image.

I have found that GPU can effectively accelerate, with approximately 30-40ms per image on 3090ti. The problem is that the speed will be slower when running the first inference, I'm not sure why

@silinsi, it should very fast to run EfficientSAM on GPU. Can you share more information?

@liutongkun, for the first inference, loading the model to GPU and moving the data to GPU may take time. Can you share the latency for the first inference?

Thanks for your reply. I put the data and model to GPU before starting the timing, here are my codes based on EfficientSAM_example.py

for i in range(10):
    device = torch.device('cuda' if torch.cuda.is_available() else 'cpu')
    model = model.to(device)
    a = sample_image_tensor[None, ...]
    a = a.to(device)
    input_points = input_points.to(device)
    input_labels = input_labels.to(device)
    t1 = time.time()
    print('Running inference using ', model_name)
    predicted_logits, predicted_iou = model(
        a,
        input_points,
        input_labels,
    )
    t2 = time.time()
    print(f'timecost{t2-t1}')

and it shows:

@liutongkun, can you move the model/data before the loop?

@liutongkun, can you move the model/data before the loop?

I modify the code to:

device = torch.device('cuda' if torch.cuda.is_available() else 'cpu')
model = models['efficientsam_ti'].to(device)
a = sample_image_tensor[None, ...]
a = a.to(device)
input_points = input_points.to(device)
input_labels = input_labels.to(device)
for i in range(10):
    t1 = time.time()
    print('Running inference u sing ', 'efficientsam_ti')
    predicted_logits, predicted_iou = model(
        a,
        input_points,
        input_labels,
    )
    t2 = time.time()
    print(f'timecost{t2-t1}')

and it shows:
