This still gives me

[7/7] RUN npx dalai alpaca install 7b:
#11 3.219 mkdir /root/dalai
#11 3.222 { method: 'install', callparams: [ '7b' ] }
#11 3.232 ERROR [Error: ENOENT: no such file or directory, rename '/root/dalai/alpaca/models' -> '/root/dalai/tmp/models'] {
#11 3.232 errno: -2,
#11 3.232 code: 'ENOENT',
#11 3.232 syscall: 'rename',
#11 3.232 path: '/root/dalai/alpaca/models',
#11 3.232 dest: '/root/dalai/tmp/models'

@wacastel
Thanks for the great work. I'm a noob in npx packages. Could you tell me how to install this commit locally?
