So i recently imported dataset from this website. And even though i have it in my files in google colab(unzipped and all that stuff), i dont know how to implement it in the code itself. Like from tutorial of Fashion mnist by tensorflow it loaded as

fashion_mnist = tf.keras.datasets.fashion_mnist

(train_images, train_labels), (test_images, test_labels) = fashion_mnist.load_data()

how do i import/load data to code cell and work with it by splitting into classes(because in that tutorial dataset has several classes and in my custom dataset it has 12) pls how to do it?

import tensorflow as tf
from tensorflow.keras.preprocessing.image import ImageDataGenerator

# Define paths to your training and validation directories
train_dir = 'garbage-classification/train'
val_dir = 'garbage-classification/validation'

# Create an ImageDataGenerator for data augmentation
train_datagen = ImageDataGenerator(rescale=1./255)
val_datagen = ImageDataGenerator(rescale=1./255)

# Load images from directories
train_generator = train_datagen.flow_from_directory(
    train_dir,
    target_size=(150, 150),  # Resize images as needed
    batch_size=32,
    class_mode='categorical'  # Use 'categorical' if you have multiple classes
)

validation_generator = val_datagen.flow_from_directory(
    val_dir,
    target_size=(150, 150),
    batch_size=32,
    class_mode='categorical'
)

i used perplexity to try to solve and it gave me this. It obviously didn't work so..

• python
• tensorflow
• machine-learning
• keras

The steps to download Kaggle datasets in Google Colab, including installing the Kaggle API, uploading the Kaggle API key, setting up authentication, downloading the dataset, unzipping the data (if necessary), and accessing the data.I have downloaded garbage_classification dataset and split it into training and validation are all executed in the following gist.
