import cupy error: .../nvrtc.cpython-39-x86_64-linux-gnu.so: undefined symbol: nvrtcGetNVVMSize, version libnvrtc.so.11.2 - cupy

Question

I'm using GTX2080 on Ubuntu 22.04
here's the output of nvcc --version:
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2022 NVIDIA Corporation
Built on Wed_Jun__8_16:49:14_PDT_2022
Cuda compilation tools, release 11.7, V11.7.99
Build cuda_11.7.r11.7/compiler.31442593_0
so I installed cupy using:
pip install cupy-cuda117
However, when I run import cupy it returns an import error:
---------------------------------------------------------------------------

The above exception was the direct cause of the following exception:

================================================================
Failed to import CuPy.
If you installed CuPy via wheels (cupy-cudaXXX or cupy-rocm-X-X), make sure that the package matches with the version of CUDA or ROCm installed.
On Linux, you may need to set LD_LIBRARY_PATH environment variable depending on how you installed CUDA/ROCm.
On Windows, try setting CUDA_PATH environment variable.
Check the Installation Guide for details:
https://docs.cupy.dev/en/latest/install.html
Original error:
ImportError: /home/sam/anaconda3/lib/python3.9/site-packages/cupy_backends/cuda/libs/nvrtc.cpython-39-x86_64-linux-gnu.so: undefined symbol: nvrtcGetNVVMSize, version libnvrtc.so.11.2
================================================================
it says "On Linux, you may need to set LD_LIBRARY_PATH environment variable depending on how you installed CUDA/ROCm." I've edit the .bashrc file to include the path of cuda:
export PATH="/usr/local/cuda-11.7/bin:$PATH"
export LD_LIBRARY_PATH=/usr/local/cuda-11.7/lib64\
${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
but still no luck, same import error. I tried reboot but same result... Thanks for any help!
