However, the unclear license may affect your usage rights. - **Requirements:** Ensure you have a suitable environment to run Jupyter Notebooks and have some understanding of Pytorch.; You should be comfortable with Chinese or capable of translating the resources for better comprehension. - **Adopt for:** CV is a comprehensive set of Jupyter Notebook-guided resources for learning about deep learning, particularly within computer vision and natural language processing using the Pytorch framework. - **License detail:** The license status for CV is unknown. Verify compatibility with your project's licensing requirements before using. ## Decision facts: MegEngine - **Adopt for:** MegEngine是一个快速、可扩展且支持自动求导的深度学习框架，适用于多种平台和环境。它主要用C++编写，并以Apache-2.0许可分发。 ## Choose when ### Choose CV if… - CV is primarily Jupyter Notebook; MegEngine is C++. - Pricing: CV is apparently offered freely. However, the unclear license may affect your usage rights.. - Requirements: Ensure you have a suitable environment to run Jupyter Notebooks and have some understanding of Pytorch.; You should be comfortable with Chinese or capable of translating the resources for better comprehension.. - Tags unique to CV: agent, agents, book, chinese. - Also covers Computer Vision. - When you are specifically interested in deep learning projects that leverage Pytorch for tasks related to computer vision or natural language processing. ### Choose MegEngine if… - MegEngine is primarily C++; CV is Jupyter Notebook. - Tags unique to MegEngine: autograd, gpu, machine-learning, numpy. - - 当您需要在Linux、Windows（WSL或直接）、MacOS（仅限CPU）和Android设备（仅限CPU）上使用Python进行深度学习项目时 ## When NOT to use CV - Avoid using CV if your primary interest lies outside of computer vision and NLP within deep learning, since the resources heavily focus on these two areas. - Do not use this tool if you require detailed information or practical guidance in a language other than Chinese, as translation might reduce clarity. ## When NOT to use MegEngine - - 当您的项目严格要求与特定硬件或操作系统完全兼容但不在支持列表内时 - - 如果您的开发环境是Python版本低于3.6或者高于3.9，并且没有在受支持的平台上，因为MegEngine对这些Python版本和平台的支持较差 ## Common questions ### What is the difference between CV and MegEngine?
