# Use PaddlePaddle with Python and Occlum This project demonstrates how Occlum enables _unmodified_ [PaddlePaddle](https://www.paddlepaddle.org.cn/) programs running in SGX enclaves, on the basis of _unmodified_ [Python](https://www.python.org). The workload is a primary AI task from [PaddlePaddle Quick Start](https://www.paddlepaddle.org.cn/documentation/docs/zh/guides/beginner/quick_start_cn.html). The source code of the workload resides in `demo.py`. ## How to Run This tutorial is written under the assumption that you have Docker installed and use Occlum in a Docker container. Occlum is compatible with glibc-supported Python, we employ miniconda as python installation tool. You can import paddle packages using conda. Here, miniconda is automatically installed by install_python_with_conda.sh script, the required python and paddle packages for this project are also loaded by this script. Step 1 (on the host): Start an Occlum container ``` docker pull occlum/occlum:latest-ubuntu20.04 docker run -it --name=pythonDemo --device /dev/sgx/enclave occlum/occlum:latest-ubuntu20.04 bash ``` Step 2 (in the Occlum container): Download miniconda and install python to prefix position. ``` cd /root/demos/paddlepaddle bash ./install_python_with_conda.sh ``` Step 3 (in the Occlum container): Run the sample code on Occlum ``` cd /root/demos/paddlepaddle bash ./run_paddlepaddle_on_occlum.sh ```
