Tensorflow Keras Dataset Filepath within PyCharm

I have seen this question and the answer. This doesn't help. I have MAC environment. Used Anaconda. And there is no .Keras folder under users directory.

I was following a tutorial. To load the built-in MNIST dataset I used the following codes:

from tensorflow.keras.datasets import mnist

# Load MNIST data 
(x_train, y_train), (x_test,y_test) = mnist.load_data()

I am using Anaconda to install the packages and Pycharm for coding. Imported the environment in PyCharm. After showing download messages in console, it's loading the images directly from second time.

Nonetheless, I want to see the downloaded MNIST images/data to get a complete understanding. I mean I want to see if it's a zip / raw images / text data etc. I don't see a newly created folder. Does anyone where the dataset was saved by Keras within PyCharm project?

By default the data should be saved in ~/tensorflow_datasets/
