AttributeError: 'KreuzbergLoader' object has no attribute 'n_ctx'

[cromagnone]

On issuing rocketrag prepare --data-dir=/my/data the program fails with:

AttributeError: 'KreuzbergLoader' object has no attribute 'n_ctx'

Is there a possible problem with the llamacpp package/dependencies as installed?
