> This method will download and install`paddlepaddle-v1.7.2-cpu`,if you are prompted that `PaddlePaddle` can not be installed automatically,You need to install `PaddlePaddle` manually,and then install `Paddlerec` again:
> - Other installation problems can be raised in [Paddle Issue](https://github.com/PaddlePaddle/Paddle/issues) or [PaddleRec Issue](https://github.com/PaddlePaddle/PaddleRec/issues)
After installing `PaddleRec`,You need to manually install `paddlepaddle-gpu`,select the appropriate version according to your environment (CUDA / cudnn),please refer to the installation tutorial[Installation Manuals](https://www.paddlepaddle.org.cn/documentation/docs/en/install/index_en.html)
We take the `dnn` algorithm as an example to introduce the quick start of `PaddleRec`, and we took 100 pieces of training data from [Criteo Dataset](https://www.kaggle.com/c/criteo-display-ad-challenge/):
