In your opinion, Python Daniel should have this book In the latest topic, 80% of readers think that Python is the best programming language. There are many similar issues, such as how to get started with Python? How to get started with Python in three months? Although there are many ways to learn Python, but to lay a solid foundation, the Knowledge System of Python must be accumulated by reading professional books.

Why does Python play the leading language in the AI age? Who will become the first development language in the AI and Big Data age? This is an issue that does not need to be discussed. If Matlab, Scala, R, Java, and Python had their own opportunities three years ago, and the situation was still unclear, the trend would have been quite clear three years later, in particular, since Facebook opened up PyTorch two days ago, the position of Python as the

Autograd1、深度学习的算法本质上是通过反向传播求导数，Pytorch的Autograd模块实现了此功能；在Tensor上的所有操作，Autograd都能为他们自动提供微分，避免手动计算导数的复杂过程。2、autograd.Variable是Autograd中的核心类，它简单的封装了Tensor，并支持几乎所有Tensor操作；Tensor被封装为Variable之后，可以调用它的.backward()实现反向传播，自动计算所有的梯度。3、Variable主要包含三个属性： data：保存Variable所包含的Tensor； grad：保存data对应的梯度，grad也是个Variable，而不是Tensor，它和data的形状一样； grad_fn：指向一个Function对象，这个Function用来反向传播计算输入的梯度。Specific code parsing #_Author_: Monkey #!/usr/bin/env

growing number of people are programmatically defining networks in a data-dependent way (using loops and conditions) to change as the input data changes dynamically. In addition to parameterization, automatic differentiation, and the training/optimization features, this is much like a normal program. Dynamic networks have become increasingly popular (especially for NLP) thanks to deep learning frameworks such as Pytorch and Chainer (note: The previou
