什么是智能合约DApp。智能合约DApp是使用区块链技术实现去中心化应用(DApp)的核心技术。所谓智能合约是指以数字代码的形式编写的自动执行计算机程序，实现了相互协作的各方之间的权益自动执行和管理的智能合约系统。
DApp是指以区块链为底层技术平台的分布式应用程序，它使得开发者可以构建去中心化和自主运行的应用程序，并通过链上的合约机制实现代码不可更改性和事务透明性
SWAP Market Value Management Robot Main
1.The risk management measures of robots can be utilized to provide more realistic trading links for new users,as the mainstream currencies and trading depths of major exchanges can be seen.
2.Hedge trading can be carried out.After robots and real users make transactions,in order to reduce the risk of digital currency fluctuations,small exchanges need to use large exchanges to perform reverse operations using orders made by real users.
3.Trading depth:If the trading depth is small,the trading depth is insufficient,the trading volume is small,and the bid-ask spread is too large,making it easy to make a solar line.
Main implementation:
1 transaction depth,with several transactions per minute and all parameters adjustable
2.Pull/smash:A regular daily rise can be set at a certain time period,with a certain proportion of rise and fall,and a positive or negative line at the end of the day
3 can achieve multiple on chain transfers
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})
参数说明：
output_names:default=None
用来指定输出哪些，以及顺序
若为None，则按序输出所有的output，即返回[output_0,output_1]
若为[‘output_1’,‘output_0’]，则返回[output_1,output_0]
若为[‘output_0’]，则仅返回[output_0:tensor]
input:dict
可以通过session.get_inputs().name获得名称
其中key值要求与torch.onnx.export中设定的一致。
3.onnx模型输出与pytorch模型比对
import numpy as np
np.testing.assert_allclose(torch_result[0].detach().numpu(),onnx_result,rtol=0.0001)
