请问这是咋回事呢？是taichi版本为1.4.1

#2

我这里没有复现这个问题，看报错信息好像是参数类型有问题，你可以跑一下下面的程序么？同时，希望能吧命令行输出的信息都贴上来。

import taichi as ti
import taichi.math as tm
ti.init(arch = ti.cpu)

@ti.kernel
def test(a:tm.vec2):
    print(a)


a = tm.vec2([1,2])
test(a)
#3

可以贴一下你运行 taichi 时打印出来的信息不？

可能是版本原因导致的，在1.4上就没有这个问题

1.1.2 的时候 dynamic snode 还不支持除 int32 之外的类型。marching_squares 这个例子也是在 1.4 里面更新，使用了 dynamic snode 的功能。
