2. usage

import torch
from efficient_linear_decoding.efficient_linear_decoding import causal_linear_decoder

# Create input tensor
Q = torch.randn(2,32,1024,128,device='cuda:0')
K = torch.randn(2,32,1024,128,device='cuda:0')
V = torch.randn(2,32,1024,128,device='cuda:0')

# Inference using causal_linear_decoder
output = causal_linear_decoder(Q,K,V)

# If you want to input a mask with weight, set the is_mask_weight: True
gamma = torch.full((32,),0.5,device='cuda:0')
output = causal_linear_decoder(Q,K,V,is_mask_weight=True,gamma=gamma)
