 To install, you can use this command:
 ```
-python -m pip install llama-cpp-python==0.1.66+cu117 --find-links=https://jllllll.github.io/llama-cpp-python-cuBLAS-wheels/cu117
+python -m pip install llama-cpp-python==0.1.66+cu177 --extra-index-url=https://jllllll.github.io/llama-cpp-python-cuBLAS-wheels/AVX2/cu117
 ```
-This will install llama-cpp-python 0.1.66 for CUDA 11.7. You can change both instances of `cu117` to change the CUDA version.
