# we need to do device version validation (for example to check Cuda version for an onnxruntime-training package).
# in order to know whether the onnxruntime package is for training it needs
# to do import onnxruntime.training.ortmodule first.
# onnxruntime.capi._pybind_state is required before import onnxruntime.training.ortmodule.
# however, import onnxruntime.capi._pybind_state will already raise an exception if a required Cuda version
# is not found.
# here we need to save the exception and continue with Cuda version validation in order to post
# meaningful messages to the user.
# the saved exception is raised after device version validation.
