PERFORMANCE COMPARISON BETWEEN PYTORCH AND MINDSPORE Xiangyu XIA and Shaoxiang ZHOU Department of Information, Beijing City University, Beijing 100191 Supported by Beijing City University in 2021 “the innovation and entrepreneurship training program for college students” ABSTRACT Deep learning has been well used in many fields. However, there is a large amount of data when training neural networks, which makes many deep learning frameworks appear to serve deep learning practitioners, providing services that are more convenient to use and perform better. MindSpore and PyTorch are both deep learning frameworks. MindSpore is owned by HUAWEI, while PyTorch is owned by Facebook. Some people think that HUAWEI's MindSpore has better performance than FaceBook's PyTorch, which makes deep learning practitioners confused about the choice between the two. In this paper, we perform analytical and experimental analysis to reveal the comparison of training speed of MIndSpore and PyT...
