Installation

This document covers how to install PaddleDetection and its dependencies (including PaddlePaddle), together with COCO and Pascal VOC dataset.

For general information about PaddleDetection, please see README.md.

Requirements:

  • PaddlePaddle 2.1
  • OS 64 bit
  • Python 3(3.5.1+/3.6/3.7/3.8/3.9)，64 bit
  • pip/pip3(9.0.1+), 64 bit
  • CUDA >= 10.1
  • cuDNN >= 7.6

Dependency of PaddleDetection and PaddlePaddle:

PaddleDetection version PaddlePaddle version tips
release/2.1 >= 2.1.0 Dygraph mode is set as default
release/2.0 >= 2.0.1 Dygraph mode is set as default
release/2.0-rc >= 2.0.1 --
release/0.5 >= 1.8.4 Cascade R-CNN and SOLOv2 depends on 2.0.0.rc
release/0.4 >= 1.8.4 PP-YOLO depends on 1.8.4
release/0.3 >=1.7 --

Instruction

1. Install PaddlePaddle


# CUDA10.1
python -m pip install paddlepaddle-gpu==2.1.0.post101 -f https://paddlepaddle.org.cn/whl/mkl/stable.html

# CPU
python -m pip install paddlepaddle -i https://mirror.baidu.com/pypi/simple

Please make sure that your PaddlePaddle is installed successfully and the version is not lower than the required version. Use the following command to verify.

# check
>>> import paddle
>>> paddle.utils.run_check()

# confirm the paddle's version
python -c "import paddle; print(paddle.__version__)"

Note

  1. If you want to use PaddleDetection on multi-GPU, please install NCCL at first.

2. Install PaddleDetection

PaddleDetection can be installed in the following two ways:

2.1 Install via pip

Note: Installing via pip only supports Python3

# Install paddledet via pip
pip install paddledet==2.1.0 -i https://mirror.baidu.com/pypi/simple

# Download and use the configuration files and code examples in the source code
git clone https://github.com/PaddlePaddle/PaddleDetection.git
cd PaddleDetection

2.2 Compile and install from Source code

# Clone PaddleDetection repository
cd <path/to/clone/PaddleDetection>
git clone https://github.com/PaddlePaddle/PaddleDetection.git

# Compile and install paddledet
cd PaddleDetection
python setup.py install

# Install other dependencies
pip install -r requirements.txt

Note

  1. If you are working on Windows OS, pycocotools installing may failed because of the origin version of cocoapi does not support windows, another version can be used used which only supports Python3:

    pip install git+https://github.com/philferriere/cocoapi.git#subdirectory=PythonAPI

  2. If you are using Python <= 3.6, pycocotools installing may failed with error like distutils.errors.DistutilsError: Could not find suitable distribution for Requirement.parse('cython>=0.27.3'), please install cython firstly, for example pip install cython

After installation, make sure the tests pass:

python ppdet/modeling/tests/test_architectures.py

If the tests are passed, the following information will be prompted:

.....

OK

Inference demo

Congratulation! Now you have installed PaddleDetection successfully and try our inference demo:

# Predict an image by GPU
export CUDA_VISIBLE_DEVICES=0
python tools/infer.py -c configs/ppyolo/ppyolo_r50vd_dcn_1x_coco.yml -o use_gpu=true weights=https://paddledet.bj.bcebos.com/models/ppyolo_r50vd_dcn_1x_coco.pdparams --infer_img=demo/000000014439.jpg

An image of the same name with the predicted result will be generated under the output folder. The result is as shown below：
