Quick Start

Prerequisites

  • python >= 3.6
  • Pytorch >= 1.5
  • mmcv >= 1.2.0
  • nvidia-dali == 0.25.0

Installation

Prepare environment

  1. Create a conda virtual environment and activate it.

    conda create -n ev python=3.6 -y
conda activate ev

  2. Install PyTorch and torchvision

    The master branch works with PyTorch 1.5.1 or higher.

    conda install pytorch==1.7.0 torchvision==0.8.0 -c pytorch

  3. Install some python dependencies

    replace {cu_version} and {torch_version} to the version used in your environment

    # install mmcv
pip install mmcv-full==1.4.4 -f https://download.openmmlab.com/mmcv/dist/{cu_version}/{torch_version}/index.html
# for example, install mmcv-full for cuda10.1 and pytorch 1.7.0
pip install mmcv-full==1.4.4 -f https://download.openmmlab.com/mmcv/dist/cu101/torch1.7.0/index.html

# install nvidia-dali
pip install http://pai-vision-data-hz.oss-cn-zhangjiakou.aliyuncs.com/third_party/nvidia_dali_cuda100-0.25.0-1535750-py3-none-manylinux2014_x86_64.whl

# install common_io for MaxCompute table read (optional)
pip install https://pai-vision-data-hz.oss-cn-zhangjiakou.aliyuncs.com/third_party/common_io-0.3.0-cp36-cp36m-linux_x86_64.whl

  4. Install EasyCV

    You can simply install easycv with the following command:

    pip install pai-easycv

    or clone the repository and then install it:

    git clone https://github.com/Alibaba/EasyCV.git
cd easycv
pip install -r requirements.txt
pip install -v -e .  # or "python setup.py develop"

  5. Install pai_nni and blade_compressin

    When you use model quantize and prune, you need to install pai_nni and blade_compression with the following command:

    # install torch >= 1.8.0
pip install torch==1.8.0 torchvision==0.9.0 torchaudio==0.8.0

# install mmcv >= 1.3.0 (torch version >= 1.8.0 does not support mmcv version < 1.3.0)
pip install mmcv-full==1.4.4 -f https://download.openmmlab.com/mmcv/dist/{cu_version}/{torch_version}/index.html

# install onnx and pai_nni
pip install onnx
pip install https://pai-nni.oss-cn-zhangjiakou.aliyuncs.com/release/2.5/pai_nni-2.5-py3-none-manylinux1_x86_64.whl

# install blade_compression
pip install http://pai-vision-data-hz.oss-cn-zhangjiakou.aliyuncs.com/third_party/blade_compression-0.0.1-py3-none-any.whl

  6. If you want to use MSDeformAttn, you need to compiling CUDA operators

    cd easycv/thirdparty/deformable_attention/
python setup.py build install
# unit test (should see all checking is True)
python test.py
cd ../../..

Verification

Simple verification

from easycv.apis import *

You can also verify your installation using following quick-start examples
