infer.py file from forecasting-pipelines sample folder

Start by comparing infer.py from the forecasting-pipelines sample with the traceback locations at lines 39 and 154, then reproduce the inference pipeline using the reported sales data and arguments. Investigate the Azure ML dataset registration failure and confirm that the pipeline completes successfully without the invalid-file error.

Hi
Im using the forecasting-pipelines sample, to build a training and inference pipeline. The training pipeline is running without error (I am using some public sales data) but the inferene pipeline is giving me this error:

I am using the infor.py copied directly from the sample "forecasting-pipelines" file - does it have to be change in some way? or is it something else that is causing the error?
