python中的numpy怎么读,tensorflow和pytorch

1.1从列表到编号

ndarray=NP.Array(list ) 1.2 numpy到list

list=ndarray.tolist () 2.1从list到torch.Tensor

tensor=torch.tensor(list ) 2.2 torch.Tensor到list

首先进入numpy，然后进入list

list=tensor.numpy(.tolist ) ) 3.1 torch.Tensor到numpy

ndarray=tensor_name.numpy(*GPU上的tensor无法直接转换为numpy

ndarray=tensor_name.CPU(.numpy ) ) 3.2 numpy到torch.Tensor

tensor=torch.from _ numpy (nd array )或

tensor=torch.tensor(nd.array )注：实践中，数组nd.array类型迁移到tensor，方式tensor=torch.from_numpy ) ndarray为toray
