Why not base on CPython?

[yang8621]

This project is based on PyPy interpreter. Why not put CPython to SGX? CPython is more widely used.

Two main reasons of using PyPy are: 

• safer (memory safe) than CPython, this is important for applications in SGX enclave
• faster (supporting JIT)

Historically, CPython has some memory issues because of using C/C++, and could be even worse in enclave. We care a lot about memory safety. That's why we are using Rust as the main language for developing enclaves.

How should I setup the mesapy env locally?Or how to print the running error in mesalock-linux? I build a machine learning model with python3. But can not execute this script in mesalock-linux. I don't know how the change the script to integrate mesalock-linux.
