I'm a newcomer to Machine Learning. It's my pleasure to run your code. When I run split_dataset.py, no data is copied into folders train and test. I copy the data from folder original_dataset into folders test and train, and run train.py will report an error:

I'm also a newcomer to tensorflow. How can I solve this problem?
You don't have to use the data pipeline to process the data, you can use tensorflow_datasets or keras.datasets to load the input data, unless the data you are training on aren't included in these datasets, in which case you can still use tf.data.Dataset to process the data.
keras.datasets
tensorflow_datasets
tf.data.Dataset
I was trying to write some tutorial on tensorflow, the first note I made is about the tensorflow_datasets. If you need, you can check it out as well.
