import taichi as ti

@ti.data_oriented
class TestClass:
def __init__(self):
self.a = ti.ndarray(ti.i32, shape=10000)

def test_kernel(self):
for i in range(10000):

def test(self):
self.test_kernel()
test = TestClass()
test.test()
以上代码会报错

仅仅将
self.a = ti.ndarray(ti.i32, shape=10000)
改为
self.a = ti.field(ti.i32, shape=10000)
就没有报错
