feat: support tensor parallel & Data loader #2528

	# CI for specifically ensuring integrations work fine (`transformers` mainly)
	# Useful tips:
	# - New integrations to test should have its own job, and follow a strategy method where we check both
	# the pypi and github versions.
	# - When checking the latest release of the integration, use
	# git checkout $(git describe --tags `git rev-list --tags --max-count=1`) to get the latest release.
