[BUG] rope scaling with phi3 models

[arunpatala]

Hi,

I am trying to train phi3 mini model with longer context length 8192 than its default length of 4096.
I understand that reope scaling is not supported for models with sliding window. How can I proceed
from this to train a phi3 model with longer context? should i finetune the base model to extend its
context length? which methods can i use? Is there a plan to support in future?

@arunpatala Oh yep that is an issue - planning to support the 128K Phi later down the road
