Choose ColossalAI if…
- ColossalAI is primarily Python; MegEngine is C++.
- Tags unique to ColossalAI: ai, big-model, data-parallelism, distributed-computing.
- Also covers Inference & Serving.
- You require handling extremely large AI models with massive context windows, such as over 2M tokens.
When NOT to use ColossalAI
- You are working in an environment that does not support Linux OS, as ColossalAI currently offers no support for other operating systems.
- Your current CUDA version is less than 11.0 or your GPU compute capability is below 7.0 (pre-V100/RTX20 series).
- You cannot satisfy the minimum hardware and software requirements specified, such as PyTorch >= 2.2 and Python >= 3.7.
Choose MegEngine if…
- MegEngine is primarily C++; ColossalAI is Python.
- 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 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
