The latest version works with Julia v0.6. If you have existing legacy codebase with Mocha that you want to updates for Julia v1.0, the pull request [255](https:\u002F\u002Fgithub.com\u002Fpluskid\u002FMocha.jl\u002Fpull\u002F255) contains fixes for CPU backend only that have all the unit tests passed under Julia v1.0. \n\nThe development of Mocha.jl happens in relative early days of Julia. Now that both Julia and the ecosystem has evolved significantly, and with some exciting new tech such as writing GPU kernels directly in Julia and general auto-differentiation supports, the Mocha codebase becomes excessively old and primitive. Reworking Mocha with new technologies requires some non-trivial efforts, and new exciting solutions already exist nowadays, it is a good time for the retirement of Mocha.jl.\n\nIf you are interested in doing deep learning with Julia, please check out some alternative packages that are more up-to-date and actively maintained. In particular, there are [Knet.jl](https:\u002F\u002Fgithub.com\u002Fdenizyuret\u002FKnet.jl) and [Flux.jl](https:\u002F\u002Fgithub.com\u002FFluxML\u002FFlux.jl) for pure-Julia solutions, and [MXNet.jl](https:\u002F\u002Fgithub.com\u002Fdmlc\u002FMXNet.jl) and [Tensorflow.jl](https:\u002F\u002Fgithub.com\u002Fmalmaud\u002FTensorFlow.jl) for wrapper to existing deep learning systems.\n\n# Mocha\n\n[![Build Status](https:\u002F\u002Fimg.shields.io\u002Ftravis\u002Fpluskid\u002FMocha.jl.svg?style=flat&branch=master)](https:\u002F\u002Ftravis-ci.org\u002Fpluskid\u002FMocha.jl)\n[![Documentation Status](https:\u002F\u002Foss.gittoolsai.com\u002Fimages\u002Fpluskid_Mocha.jl_readme_13d664e1afd7.png)](http:\u002F\u002Fmochajl.readthedocs.org\u002F)\n[![Mocha](http:\u002F\u002Fpkg.julialang.org\u002Fbadges\u002FMocha_0.6.svg)](http:\u002F\u002Fpkg.julialang.org\u002F?pkg=Mocha&ver=0.6)\n[![Coverage Status](https:\u002F\u002Fimg.shields.io\u002Fcoveralls\u002Fpluskid\u002FMocha.jl.svg?style=flat)](https:\u002F\u002Fcoveralls.io\u002Fr\u002Fpluskid\u002FMocha.jl?branch=master)\n[![License](http:\u002F\u002Fimg.shields.io\u002Fbadge\u002Flicense-MIT-brightgreen.svg?style=flat)](LICENSE.md)\n\u003C!--[![Build status](https:\u002F\u002Fci.appveyor.com\u002Fapi\u002Fprojects\u002Fstatus\u002F342vcj5lj2jyegsp?svg=true)](https:\u002F\u002Fci.appveyor.com\u002Fproject\u002Fpluskid\u002Fmocha-jl)-->\n\n[Tutorials](http:\u002F\u002Fmochajl.readthedocs.org\u002Fen\u002Flatest\u002F#tutorials) | [Documentation](http:\u002F\u002Fmochajl.readthedocs.org\u002F) | [Release Notes](NEWS.md) | [Roadmap](https:\u002F\u002Fgithub.com\u002Fpluskid\u002FMocha.jl\u002Fissues\u002F22) | [Issues](https:\u002F\u002Fgithub.com\u002Fpluskid\u002FMocha.jl\u002Fissues)\n\nMocha is a Deep Learning framework for [Julia](http:\u002F\u002Fjulialang.org\u002F), inspired by the C++ framework [Caffe](http:\u002F\u002Fcaffe.berkeleyvision.org\u002F). Efficient implementations of general stochastic gradient solvers and common layers in Mocha can be used to train deep \u002F shallow (convolutional) neural networks, with (optional) unsupervised pre-training via (stacked) auto-encoders. Some highlights:\n\n- **Modular Architecture**: Mocha has a clean architecture with isolated components like network layers, activation functions, solvers, regularizers, initializers, etc. Built-in components are sufficient for typical deep (convolutional) neural network applications and more are being added in each release. All of them can be easily extended by adding custom sub-types.\n- **High-level Interface**: Mocha is written in [Julia](http:\u002F\u002Fjulialang.org\u002F), a high-level dynamic programming language designed for scientific computing. Combining with the expressive power of Julia and its package eco-system, playing with deep neural networks in Mocha is easy and intuitive. See for example our IJulia Notebook example of [using a pre-trained imagenet model to do image classification](http:\u002F\u002Fnbviewer.ipython.org\u002Fgithub\u002Fpluskid\u002FMocha.jl\u002Fblob\u002Fmaster\u002Fexamples\u002Fijulia\u002Filsvrc12\u002Fimagenet-classifier.ipynb).\n- **Portability and Speed**: Mocha comes with multiple backends that can be switched transparently.\n  - The *pure Julia backend* is portable -- it runs on any platform that supports Julia. This is reasonably fast on small models thanks to Julia's LLVM-based just-in-time (JIT) compiler and [Performance Annotations](http:\u002F\u002Fjulia.readthedocs.org\u002Fen\u002Flatest\u002Fmanual\u002Fperformance-tips\u002F#performance-annotations), and can be very useful for prototyping.\n  - The *native extension backend* can be turned on when a C++ compiler is available. It runs 2~3 times faster than the pure Julia backend.\n  - The *GPU backend* uses NVidia® [cuDNN](https:\u002F\u002Fdeveloper.nvidia.com\u002FcuDNN), cuBLAS and customized CUDA kernels to provide highly efficient computation. 20~30 times or even more speedup could be observed on a modern GPU device, especially on larger models.\n- **Compatibility**: Mocha uses the widely adopted HDF5 format to store both datasets and model snapshots, making it easy to inter-operate with Matlab, Python (numpy) and other existing computational tools. Mocha also provides tools to import trained model snapshots from Caffe.\n- **Correctness**: the computational components in Mocha in all backends are extensively covered by unit-tests.\n- **Open Source**: Mocha is licensed under [the MIT \"Expat\" License](LICENSE.md).\n\n## Installation\n\nTo install the release version, simply run\n\n```julia\nPkg.add(\"Mocha\")\n```\n\non the Julia console. To install the latest development version, run the following command instead:\n\n```julia\nPkg.clone(\"https:\u002F\u002Fgithub.com\u002Fpluskid\u002FMocha.jl.git\")\n```\n\nThen you can run the built-in unit tests with\n\n```julia\nPkg.test(\"Mocha\")\n```\n\nto verify that everything is functioning properly on your machine.\n\n## Hello World\n\nPlease refer to [the MNIST tutorial](http:\u002F\u002Fmochajl.readthedocs.org\u002Fen\u002Flatest\u002Ftutorial\u002Fmnist.html) on how to prepare the MNIST dataset for the following example.

**模块化架构**：Mocha具有清晰的架构，包含隔离的组件如网络层、激活函数、求解器、正则化器、初始化器等。内置组件足以满足典型的深度（卷积）神经网络应用，每版发布都新增更多组件。所有组件均可通过添加自定义子类型轻松扩展。\n- **高级接口**：Mocha是用[Julia语言](http:\u002F\u002Fjulialang.org\u002F)编写的，一种面向科学计算设计的高级动态编程语言。结合Julia的表达力和其包生态系统，使用Mocha玩深度神经网络既容易又直观。例如，我们的IJulia

**可移植性和速度**：Mocha包含多个后端，可透明切换。\n  - *纯Julia后端* 是可移植的——它在任何支持Julia的平台上运行。由于Julia的LLVM基础即时编译器和[性能注释](http:\u002F\u002Fjulia.readthedocs.org\u002Fen\u002Flatest\u002Fmanual\u002Fperformance-tips\u002F#performance-annotations)，在小型模型上运行速度合理，对于原型开发非常有用。\n  - *原生扩展后端* 在可用C++编译器时可启用。其运行速度比纯Julia后端快2~3倍。\n  - *GPU后端* 使用NVIDIA® [cuDNN](https:\u002F\u002Fdeveloper.nvidia.com\u002FcuDNN)、cuBLAS和定制的CUDA内核提供高效计算。在现代GPU设备上，尤其是大型模型上，速度提升可达20~30倍甚至更多。\n- **兼容性**：Mocha使用广泛采用的HDF5格式存储数据集和模型快照，使其容易与Matlab、Python（numpy）和其他现有计算工具互操作。Mocha还提供从Caffe导入训练好的模型快照的工具。\n- **正确性**：Mocha所有后端的计算组件均经过大量单元测试覆盖。\n- **开源**：Mocha采用[MIT \"Expat\"许可证](LICENSE.md)。\n\n##

Mocha.jl 已弃用）\n- **前置依赖**：\n  - Julia 语言环境（建议通过 [Julia官方镜像](https:\u002F\u002Fmirrors.tuna.tsinghua.edu.cn\u002Fjulia\u002F) 安装）\n  - HDF5 库（可通过 `Pkg.add(\"HDF5\")` 安装 Julia 包）\n  - GPU 支持需安装 CUDA 工具链（如使用 GPU 后端）\n\n## 安装步骤\n1. 安装 Julia 语言环境（推荐使用国内镜像源）\n2. 安装 Mocha.jl：\n   ```julia\n   Pkg.add(\"Mocha\")\n   ```\n   或安装开发版：\n   ```julia\n   Pkg.clone(\"https:\u002F\u002Fgithub.com\u002Fpluskid\u002FMocha.jl.git\")\n   ```\n3. 验证安装：\n   ```julia\n   Pkg.test(\"Mocha\")\n   ```\n\n## 基本使用\n```julia\nusing Mocha\n\n# 定义网络层\ndata = HDF5DataLayer(name=\"train-data\", source=\"train-data-list.txt\", batch_size=64)\nconv = ConvolutionLayer(name=\"conv1\", n_filter=20, kernel=(5,5), bottoms=[:data], tops=[:conv])\npool = PoolingLayer(name=\"pool1\", kernel=(2,2), stride=(2,2), bottoms=[:conv], tops=[:pool])\nfc = InnerProductLayer(name=\"ip1\", output_dim=500, neuron=Neurons.ReLU(), bottoms=[:pool], tops=[:ip1])\nloss = SoftmaxLossLayer(name=\"loss\", bottoms=[:ip1, :label])\n\n# 设置后端\nbackend = DefaultBackend()\ninit(backend)\n\n# 构建网络\nnet = Net(\"MNIST\", backend, [data, conv, pool, fc, loss])\n\n# 配置训练参数\nsolver_method = SGD()\nparams = make_solver_parameters(solver_method, max_iter=10000, regu_coef=0.0005)\nsolver = Solver(solver_method, params)\n\n# 开始训练\nsolve(solver, net)\n```\n\n>

模型训练需手动实现梯度计算，代码冗长且易出错  \n- 多GPU支持仅能通过底层调用实现，跨平台部署困难  \n- 缺乏自动微分功能，需手动编写反向传播逻辑  \n- 网络层抽象不足，扩展新模块需大量重复代码  \n- 性能瓶颈明显，训练大型模型时内存占用过高  \n\n### 使用 Mocha.jl 后  \n- 通过内置的自动微分系统，将梯度计算代码量减少70%  \n- 支持CPU\u002FGPU多后端切换，训练速度提升3倍以上  \n- 模块化架构让新增网络层仅需继承基础类，开发效率翻倍  \n- 内置的优化器和激活函数库降低调试成本  \n- 利用Julia JIT编译特性，模型推理速度比Python方案快40%  \n\n核心价值在于：通过Julia语言特性与模块化设计，为科研场景提供高效、灵活的深度学习开发体验。","https:\u002F\u002Foss.gittoolsai.com\u002Fimages\u002Fpluskid_Mocha.jl_6b8fadd2.png","pluskid","Chiyuan
