如何在Python中创建数据类型为cl.cltypes.uint2的变量

import pyopencl as cl

platform = cl.get_platforms()[0]
device = platform.get_devices()[0]
context = cl.Context([device])
queue = cl.CommandQueue(context)

import numpy as np
data = np.zeros(1, dtype=cl.cltypes.uint2)

data_buffer = cl.Buffer(context, cl.mem_flags.READ_WRITE | cl.mem_flags.COPY_HOST_PTR, hostbuf=data)

kernel_code = """
__kernel void my_kernel(__global uint2* data) {
    // 在这里编写内核逻辑
}
"""
program = cl.Program(context, kernel_code).build()

program.my_kernel(queue, data.shape, None, data_buffer)

cl.enqueue_copy(queue, data, data_buffer)

import pyopencl as cl
import numpy as np

# 创建OpenCL上下文和命令队列
platform = cl.get_platforms()[0]
device = platform.get_devices()[0]
context = cl.Context([device])
queue = cl.CommandQueue(context)

# 定义数据类型为cl.cltypes.uint2的变量
data = np.zeros(1, dtype=cl.cltypes.uint2)

# 将数据传输到设备上的内存
data_buffer = cl.Buffer(context, cl.mem_flags.READ_WRITE | cl.mem_flags.COPY_HOST_PTR, hostbuf=data)

# 创建内核程序
kernel_code = """
__kernel void my_kernel(__global uint2* data) {
    // 在这里编写内核逻辑
}
"""
program = cl.Program(context, kernel_code).build()

# 设置内核参数并执行内核
program.my_kernel(queue, data.shape, None, data_buffer)

# 从设备上的内存中读取结果
cl.enqueue_copy(queue, data, data_buffer)

print(data)
