Hi qsimeng, This may be because you didn't set the absolute Optix path in config.py.

Add the directory containing the file /NVIDIA-OptiX-SDK-6.5.0-linux64/lib64/liboptix_prime.so.6.5.0 to the system environment variable (such as LD_LIBRARY_PATH).

If the library file is not present in the default library search path, you can try creating a symbolic link pointing to the actual library file so that the system can locate it. Use the following command:

ln -s /actual/path/to/liboptix_prime.so.6.5.0 /usr/lib/liboptix_prime.so.6.5.0
