多gpu支持

[WuXunjin]

请问如何支持多GPU？单卡3090只能用lite模型save_memory，尝试修改app.py

parser.add_argument("--t2i_device", default="cuda:0", type=str)
parser.add_argument("--i2v_device", default="cuda:1", type=str)
parser.add_argument("--v2m_device", default="cuda:2", type=str)
parser.add_argument("--render_device", default="cuda:3", type=str)

报错

File "/home/admin/.conda/envs/hunyuan/lib/python3.9/site-packages/torch/nn/modules/linear.py", line 125, in forward
return F.linear(input, self.weight, self.bias)
RuntimeError: Expected all tensors to be on the same device, but found at least two devices, cuda:2 and cuda:0! (when checking argument for argument mat1 in method wrapper_CUDA_addmm)
