HF_HUB_OFFLINE environment variable not being honoured for Neuron cache

[unography]

System Info

Docker Image:

763104351884.dkr.ecr.{region_name}.amazonaws.com/huggingface-pytorch-training-neuronx:2.1.2-transformers4.43.2-neuronx-py310-sdk2.20.0-ubuntu20.04

Who can help?

Information

• The official example scripts
• My own modified scripts

Tasks

• An officially supported task in the examples folder (such as GLUE/SQuAD, ...)
• My own task or dataset (give details below)

Reproduction (minimal, reproducible, runnable)

Running any custom model where the Neuron compilation needs to run again, the script attempts to synchronize the cache with the aws-neuron repo.
However, if HF_HUB_OFFLINE is set - this sync should not happen

This issue wasn't there on an earlier version, when using optimum-neuron==0.0.22

Expected behavior

No API calls to the Hub is made when HF_HUB_OFFLINE is set - huggingface_hub.errors.OfflineModeIsEnabled should be handled.
This was already being handled in an earlier version, optimum-neuron==0.0.22
