WebUX Limitations. functorch, like JAX, has restrictions around what can be transformed. In general, JAX’s limitations are that transforms only work with pure functions: that is, functions where the output is completely determined by the input and that do not involve side effects (like mutation). We have a similar guarantee: our transforms work ... Web本质上，JAX 是一种对可复合的函数变换的扩展系统。grad和jit 是这样的变换的实例。另外有 vmap用来做自动向量化和 pmap 做单一程序多数据的多加速器的并行编程。现在只 …
