简介: 区块链是分布式数据存储、点对点传输、共识机制、加密算法等计算机技术的新型应用模式

  什么是区块链?

  1、区块链(Blockchain)是分布式数据存储、点对点传输、共识机制、加密算法等计算机技术的新型应用模式。所谓共识机制是区块链系统中实现不同节点之间建立信任、获取权益的数学算法。

  2、区块链是信息技术领域的一个术语。本质上,它是一个共享数据库。其中存储的数据或信息具有“不可伪造性”、“全过程追溯性”、“可追溯性”、“公开透明性”和“集体维护性”等特征。

  3、区块链是分布式数据存储、点对点传输、共识机制、加密算法等计算机技术的新型应用模式。区块链(Blockchain),它本质上是一个去中心化的数据库。

  4、概念:区块链是分布式数据存储、点对点传输、共识机制、加密算法等计算机技术的新型应用模式

  import torch

  import onnx

  from torchvision import transforms

  import torch.nn as nn

  from torch.nn import Sequential

  #添加模型

  #设置数据转换方式

  preprocess_transform=transforms.Compose([

  transforms.ToTensor(),#把数据转换为张量(Tensor)

  transforms.Normalize(#标准化,即使数据服从期望值为0,标准差为1的正态分布

  mean=[0.5,],#期望

  import onnx

  import onnxruntime as ort

  model=onnx.load('best.onnx')

  onnx.checker.check_model(model)

  session=ort.InferenceSession('best.onnx')

  x=np.random.randn(1,3,32,32).astype(np.float32)#注意输入type一定要np.float32!!!!!

  #x=torch.randn(batch_size,chancel,h,w)

  outputs=session.run(None,input={'input':x})
