Unable to finetune using llama.cpp

[staru09]

I was following this guide to finetune using llama.cpp but was unable to follow along after this

nohup ../build/bin/finetune --model-base llama-2-13b-chat.Q5_K_M.gguf --checkpoint-in checkpoint-250.gguf --lora-out lora.bin --train-data train.txt --sample-start '<SFT>' --adam-iter 1024 & It throws a 'no such file found' error.

I tried adding an empty folder named 'finetune' to the build/bin, but the issue persists. Can anyone suggest what is needed to be done?
