TrenTorch 的路线定得很死：通篇只用 NumPy，不沾 PyTorch，从张量、自动求导一路手写到 attention、量化和 KV cache。骨架取自哈佛 CS249r 的 TinyTorch，作者自称同骨更多肌肉，还自带 tren 管进度和测试。 中文圈里同类介绍早有人写过，这条不装独家。手写框架的仓库不少，多数写到 Linear + SGD 就停了。这个把里程碑复现绑进进度，逼你拿自己写的东西去跑经典模型，比光看文档更有体感。坑也明白：它是教学重建，不是生产替代。敲完不等于能 debug 分布式，也不等于会写 CUDA。赶交付的直接走官方教程更划算；想补"框架底下在干嘛"这一层的，比再背一遍 API 有用。 官方 TinyTorch / mlsysbook 还在维护。选型时先分清：跟课走原版，还是跟这个社区重写版。别把一口气读完当成一周速成，在 NumPy 里手写卷积和 attention，时间成本不小。 项目地址：https://github.com/TrenTorch/TrenTorch
