In TensorFlow examples, I can see URLs to download the csv format of the dataset. For example,
Iris- https://storage.googleapis.com/download.tensorflow.org/data/iris_training.csv
Titanic- https://storage.googleapis.com/tf-datasets/titanic/train.csv
However, I can't find the URL for every dataset in TensorFlow that are listed over her. (https://www.tensorflow.org/datasets/catalog/overview).
you don't need the URLs. Tensorflow datasets are already ready to use. check out the tutorial here tfds guide
For titanic, it is available here titanic structured dataset
Hope this would help :)
