如何让PyCuda SourceModule编译包含设备代码的多个源文件？

import pycuda.driver as cuda
import pycuda.compiler as compiler

# 指定设备代码文件夹路径
include_dirs = ['-I/path/to/device_code']

# 编译设备代码
module = compiler.SourceModule(''.join(open('device_code/kernel1.cu').readlines()), include_dirs=include_dirs)

# 编译设备代码并禁用extern "C"
module = compiler.SourceModule(''.join(open('device_code/kernel1.cu').readlines()), include_dirs=include_dirs, no_extern_c=True)

# 合并多个设备代码源文件
source_code = ''.join(open('device_code/kernel1.cu').readlines()) + ''.join(open('device_code/kernel2.cu').readlines())

# 编译多个设备代码源文件
module = compiler.SourceModule(source_code, include_dirs=include_dirs)
