The MACs value of the GRU is abnormal

[jay678]

calflops version is: 0.3.2
code：
from calflops import calculate_flops
gru = nn.GRU(input_size=128, hidden_size=128, num_layers=1, batch_first=True)
input_tensor = torch.randn(10, 32, 128) # (seq_len, batch_size, input_size)
flops, macs, params = calculate_flops(gru, (10, 32, 128), output_as_string=True, print_results=True, print_detailed=True)
print(" calflops: flops:", flops, " param:", params, "macs:", macs)
