Could not import ctransformers package.

I am trying to run this project on a Macbook pro m1 and am getting the following stacktrace.

```
Traceback (most recent call last):

ImportError: Could not import `ctransformers` package. Please install it with `pip install ctransformers`
```

I have of course ran `pip install ctransformers`

I am also using python 3.11. Does anyone know what the issue could be?
