# Important Note: Because of ABI compatibility issues between TensorRT-LLM and NGC PyTorch,
# we need to build the TensorRT-LLM wheel from source.
#
# There are two ways to build the dynamo image with TensorRT-LLM.
# 1. Use the local TensorRT-LLM wheel directory.
# 2. Use the TensorRT-LLM wheel on artifactory.
#
# If using option 1, the TENSORRTLLM_PIP_WHEEL_DIR must be a path to a directory
# containing TensorRT-LLM wheel file along with commit.txt file with the
# <arch>_<commit ID> as contents. If no valid trtllm wheel is found, the script
# will attempt to build the wheel from source and store the built wheel in the
# specified directory. TRTLLM_COMMIT from the TensorRT-LLM main branch will be
# used to build the wheel.
#
# If using option 2, the TENSORRTLLM_PIP_WHEEL must be the TensorRT-LLM wheel
# package that will be installed from the specified TensorRT-LLM PyPI Index URL.
# This option will ignore the TRTLLM_COMMIT option. As the TensorRT-LLM wheel from PyPI
# is not ABI compatible with NGC PyTorch, you can use TENSORRTLLM_INDEX_URL to specify
# a private PyPI index URL which has your pre-built TensorRT-LLM wheel.
#
# By default, we will use option 1. If you want to use option 2, you can set
# TENSORRTLLM_PIP_WHEEL to the TensorRT-LLM wheel on artifactory.
#
# Path to the local TensorRT-LLM wheel directory or the wheel on artifactory.
