MegEngine: A Deep Learning Framework
Introduction
MegEngine is a powerful and easy-to-use deep learning framework designed to facilitate both training and inference across various platforms. It is developed with an emphasis on speed, scalability, and user-friendliness, making it a suitable choice for AI enthusiasts and professionals alike.
Key Features
1. Unified Framework for Training and Inference
MegEngine offers a seamless experience by unifying the processes of training and inference. Users can perform quantization, dynamic shape/image pre-processing, and even derivation with just a single model setup. This cohesive approach allows for a streamlined transition from model training to deploying it across different platforms. A quick start guide for this feature is available here.
2. Optimized Hardware Utilization
MegEngine stands out for its ability to run on minimal hardware requirements. By utilizing the Dynamic Tensor Rematerialization (DTR) algorithm, it significantly reduces GPU memory usage— down to one-third of the original consumption. Furthermore, MegEngine's pushdown memory planner minimizes memory usage during inference, ensuring efficient operations on varying hardware configurations.
3. High-Efficiency Inference
This framework supports high-speed and precise inference on numerous platforms including x86, Arm, CUDA, and RoCM. It operates smoothly on operating systems like Linux, Windows, iOS, Android, and Trusted Execution Environments (TEEs). The framework's advanced features can be leveraged to optimize both performance and memory usage.
Installation
MegEngine provides flexibility in its installation, supporting Python installations on Linux (64-bit), Windows (64-bit), macOS (CPU-Only) versions 10.14 and above, and Android 7+ (CPU-Only). It accommodates Python versions from 3.6 to 3.9, with various installation options detailed in their [documentation].
For users preferring pre-built binaries, installation through pip is straightforward. Execute the following commands in the terminal:
python3 -m pip install --upgrade pip
python3 -m pip install megengine -f https://megengine.org.cn/whl/mge.html
Building from Source
For those who wish to build MegEngine from the source, detailed guides are provided for both CMake builds and Python bindings on their respective README files within the source repository.
