CompileError: nvcc compilation of C:\Users\Lenovo\AppData\Local\Temp\tmpw4c5xo3e\kernel.cu failed

根据引用，出现CompileError: nvcc compilation failed的错误可能是环境配置的问题。你可以尝试在代码中添加以下片段：

import os
_path = r"D:\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.25.28610\bin\Hostx64\x64"
if os.system("cl.exe"):
    os.environ['PATH'] = ';' + _path
if os.system("cl.exe"):
    raise RuntimeError("cl.exe still not found, path probably incorrect")

mod = SourceModule("""
__global__ void doublify(float *a) {
    int idx = threadIdx.x + threadIdx.y*4;
    a[idx] *= 2;
}
""")

此代码片段的作用是设置环境变量以确保编译器能够正确找到所需的路径，并编译代码。你需要根据你的具体环境将_path变量的值修改为正确的路径。

另外，根据引用和，出现C:\Users\DELL\AppData\Local\Temp\tmpq6ryi07o.cu failed和pycuda.driver.CompileError: nvcc preprocessing failed的错误可能是由于nvcc预处理失败导致的。这可能是由于代码中存在语法错误或其他问题引起的。你需要仔细检查代码并确保它符合正确的语法和逻辑。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
