Not able to deploy elinas/vicuna-13b-4bit in SageMaker

elinas/vicuna-13b-4bit is using “transformers_version”: “4.28.0.dev0” as per generation_config.json. I could not install this transformer version using pip install when I was trying to create a container. The highest version I got was 4.27.4. So, when I do docker build, I get the below error:
ERROR: Could not find a version that satisfies the requirement transformers==4.28.0.dev0
Any advice here would be appreciated.
