Splitter/consolidator worker encountered exception while consuming source data

I am working with Visual Studio 2019 Version 16.4.1 on Windows 10.

I have tried the tutorial to generate an ML.NET image classification model from a pre-trained TensorFlow model. (Link of the tutorial: https://docs.microsoft.com/en-us/dotnet/machine-learning/tutorials/image-classification?source=docs#setup)

The model is giving the required output with the images which are given in the tutorial, but when I am trying to upload and run it with my images than it is showing me the following error.

"Unhandled Exception: System.InvalidOperationException: Splitter/consolidator worker encountered exception while consuming source data ---> System.ArgumentException: Parameter is not valid."

Below is the screenshot of the error.

This is the output at the console window.
