Is pytorch open source?

pytorch Open source ?PyTorch The predecessor was Torch, Its bottom layer and Torch Frame like , But use Python A lot of things have been rewritten , Not only more flexible , Support dynamic graph , And it provides Python Interface . It is from Torch7 Team development , It's an example. Python Priority deep learning framework , Not only can you achieve powerful GPU Speed up , It also supports dynamic neural networks .

pytorch Open source ？

PyTorch It's an open source Python Machine learning library , be based on Torch, For natural language processing applications .

It helps build deep learning models and use them in various applications . But this is not just another deep learning library . This is a scientific computing package , Specially used for tensor calculation 、 Automatic differential sum GPU Speed up . For these reasons ,PyTorch Is one of the most popular deep learning libraries , And Keras and TensorFlow And other open source deep learning libraries , Let us talk about who is the best open source deep learning library .PyTorch The predecessor was Torch, Its bottom layer and Torch Frame like , But use Python A lot of things have been rewritten , Not only more flexible , Support dynamic graph , And it provides Python Interface . It is from Torch7 Team development , It's an example. Python Priority deep learning framework , Not only can you achieve powerful GPU Speed up , It also supports dynamic neural networks .

PyTorch It can be regarded as adding GPU Supported by numpy, At the same time, it can also be regarded as a powerful deep neural network with automatic derivation function . except Facebook Outside , It has been Twitter、CMU and Salesforce And so on

PyTorch Because of its Pythonic Nature and extensibility ( That is, to implement the custom layer type 、 Network architecture, etc ), Especially popular in the research community .PyTorch Use Tensor As its core data structure , Be similar to Numpy Array . With the right software and hardware , Tensors can speed up various mathematical operations . When performing a large number of these operations in deep learning , Speed makes a huge difference .PyTorch And Python similar , Focus on ease of use , Even users with very basic programming knowledge can use deep learning in their projects .

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 .
