## Instruction
|
||||
|
||||
### 1. Install PaddlePaddle
|
||||
|
||||
```
|
||||
|
||||
# CUDA10.2
|
||||
python -m pip install paddlepaddle-gpu==2.3.2 -i https://mirror.baidu.com/pypi/simple
|
||||
|
||||
# CPU
|
||||
python -m pip install paddlepaddle==2.3.2 -i https://mirror.baidu.com/pypi/simple
|
||||
```
|
||||
|
||||
- For more CUDA version or environment to quick install, please refer to the [PaddlePaddle Quick Installation document](https://www.paddlepaddle.org.cn/install/quick)
|
||||
- For more installation methods such as conda or compile with source code, please refer to the [installation document](https://www.paddlepaddle.org.cn/documentation/docs/en/install/index_en.html)
|
||||
|
||||
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
|
||||
|
||||
|
||||
|
||||
**Note:** Installing via pip only supports Python3
|
||||
|
||||
```
|
||||
|
||||
# Clone PaddleDetection repository
|
||||
cd <path/to/clone/PaddleDetection>
|
||||
git clone https://github.com/PaddlePaddle/PaddleDetection.git
|
||||
|
||||
# Install other dependencies
|
||||
cd PaddleDetection
|
||||
pip install -r requirements.txt
|
||||
|
||||
# Compile and install paddledet
|
||||
python setup.py install
|
||||
|
||||
```
|
||||
|
||||
**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:
|
||||
|
||||
```shell
|
||||
python ppdet/modeling/tests/test_architectures.py
|
||||
```
|
||||
|
||||
If the tests are passed, the following information will be prompted:
|
||||
|
||||
```
|
||||
.......
|
||||
----------------------------------------------------------------------
|
||||
Ran 7 tests in 12.816s
|
||||
OK
|
||||
```
|
||||
|
||||
## Use built Docker images
|
||||
|
||||
> If you do not have a Docker environment, please refer to [Docker](https://www.docker.com/).
|
||||
|
||||
We provide docker images containing the latest PaddleDetection code, and all environment and package dependencies are pre-installed. All you have to do is to **pull and run the docker image**. Then you can enjoy PaddleDetection without any extra steps.
|
||||
|
||||
Get these images and guidance in [docker hub](https://hub.docker.com/repository/docker/paddlecloud/paddledetection), including CPU, GPU, ROCm environment versions.
|
||||
|
||||
If you have some customized requirements about automatic building docker images, you can get it in github repo [PaddlePaddle/PaddleCloud](https://github.com/PaddlePaddle/PaddleCloud/tree/main/tekton).
|
||||
|
||||
## 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：
