  Reposition README opening to clarify foundational PyTorch implementation status

  原因：

  当前

  This repo contains the official implementation for the NeurIPS 2019 paper Generative Modeling by Estimating Gradients of the Data Distribution, by __Yang Song__ and __Stefano Ermon__. Stanford AI Lab. **Note**: **The method has been greatly stabilized by the subsequent work Improved Techniques for Training Score-Based Generative Models (code) and more recently extended by Score-Based Generative Modeling through Stochastic Differential Equations (code). This codebase is therefore not recommended for new projects anymore.

  This repository provides the original PyTorch implementation for the NeurIPS 2019 paper 'Generative Modeling by Estimating Gradients of the Data Distribution' by Yang Song and Stefano Ermon. While this foundational codebase introduced Noise Conditional Score Networks (NCSN), please note that subsequent work has greatly stabilized and extended these methods. This specific implementation is therefore primarily recommended for historical reference and understanding the original paper, rather than for new projects.
