Comparison

DeepSpeed vs MegEngine

Verdict

Pick DeepSpeed if decisions for DeepSpeed use are driven by its capacity to handle large models efficiently using techniques such as data parallelism, model parallelism, pipeline parallelism, and compression; pick MegEngine if 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 DeepSpeed if…

  • DeepSpeed is primarily Python; MegEngine is C++.
  • Tags unique to DeepSpeed: billion-parameters, compression, data-parallelism, inference.
  • Also covers Inference & Serving.
  • - When training or inferring with PyTorch on large datasets or complex deep learning models (up to trillion parameters)

When NOT to use DeepSpeed

  • - When you are working in an environment that only supports CPU-based training without access to CUDA or ROCm compatible GPUs
  • - If your project's PyTorch version is less than 2.0, DeepSpeed may not support all of its features and optimizations effectively

Choose MegEngine if…

  • MegEngine is primarily C++; DeepSpeed is Python.
  • Tags unique to MegEngine: autograd, numpy, python, tensor.
  • - 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 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
