What is pytorch? Is pytorch a software?

With the development of science and technology , Its in-depth learning framework is becoming more and more mature ,facebook Flag pytorch It is an excellent in-depth learning framework that stands out among many frameworks . that pytorch What is it? ?pytorch Is it a software ? Today, let's take you to know pytorch.

pytorch What is it? ？

pytorch It is a very popular in-depth learning framework recently ,PyTorch yes Torch stay Python Derivation on . because Torch It's a use Lua Neural network library of language , Torch useful , however Lua It's not particularly popular , All development teams will Lua Of Torch Transplanted to a more popular language Python On ., So there was pytorch.

According to the PyTorch Introduce yourself , The biggest advantage of their family is that the neural network established is dynamic , Compared to static Tensorflow, He can deal with some problems more effectively , for instance RNN Output with varying length of time . And I think , Each has its own advantages and disadvantages , So we should be neutral . Both are big companies , Tensorflow I said I had made great efforts in distributed training , Then I will default Tensorflow At this point, we should go beyond PyTorch, however Tensorflow The static calculation diagram of makes him in RNN There's a little bit of passivity in it ( Although it solved it in other ways ), But use PyTorch When , You will be interested in this dynamic RNN Better understanding .

and Tensorflow Highly industrialized , Its underlying code … You don't understand . PyTorch Well, a little bit , If you go deep API, At least you can compare Tensorflow Understand a little more PyTorch What is the bottom of .

Finally, my suggestion is :

If you are a student , Choose any one to learn , Or slightly biased PyTorch, Because you should understand better when writing code . Understand a module , transformation Tensorflow Or other modules are easy to say .

If it's work , Follow your company , What does the company use , You just use whatever you want , Don't leave the group .

Share some of my artificial intelligence learning materials for free , For a long time , Very comprehensive . Including some AI Common framework actual combat video 、 Image recognition 、OpenCV、NLQ、 machine learning 、pytorch、 Computer vision 、 Videos such as deep learning and neural network 、 Courseware source code 、 Famous essence resources at home and abroad 、AI Hot papers 、 Industry reports, etc .

For better systematic learning AI, I recommend that you collect one .

Here are some screenshots , Free download method is attached at the end of the article .
