problem when import optix using the python toolkit

[GOONTC]

Hello, thanks so much for your contribution about the python toolkit.
I met one problem when I run the examples/hello.py after compiling the pyoptix successfully on ubuntu 18.04 with cuda 11.1.

File "hello.py", line 8, in
import optix
ImportError: /home/user1/anaconda3/envs/optix/lib/python3.7/site-packages/optix-0.0.1-py3.7-linux-x86_64.egg/optix.cpython-37m-x86_64-linux-gnu.so: undefined symbol: cudaFree

I tried changing the cuda version but still happens.

Could you please help me to solve this?

Thanks so much!
