pycuda.driver.CompileError: nvcc compilation of /tmp/tmp7hnwb4te/kernel.cu failed

python version: 3.9
cuda version: 11.6
pycuda version: pip install pycuda=2022.1

i test my first cuda code in python, but failed. The error information is here:

1 error detected in the compilation of "kernel.cu".

I don't know why. So can you give me some advices?

Looks like you've got a C/C++ error in your kernel code:

kernel.cu(6): error: expression must be a modifiable lvalue

Thank you for your information, but i can't find the kernel.cu file in this path "opt/anaconda3/envs/pytorch/lib/python3.9/site-packages/pycuda/cuda kernel.cu".
