How can Tensorflow be used to download flower dataset into the environment?
The flower dataset can be downloaded using a google API that basically links to the flower dataset. The ‘get_file’ method can be used to pass the API as a parameter. Once this is done, the data gets downloaded into the environment.

We will be using the flowers dataset, which contains images of several thousands of flowers. It contains 5 sub-directories, and there is one sub-directory for every class.
We are using the Google Colaboratory to run the below code. Google Colab or Colaboratory helps run Python code over the browser and requires zero configuration and free access to GPUs (Graphical Processing Units). Colaboratory has been built on top of Jupyter Notebook.
import numpy as np
import os
import PIL
import PIL.Image
import tensorflow as tf
import tensorflow_datasets as tfds
print("The Tensorflow version is :")
print(tf.__version__)
import pathlib
print("The dataset is being downloaded")
dataset_url = "https://storage.googleapis.com/download.tensorflow.org/example_images/flower_photos.tgz"
data_dir = tf.keras.utils.get_file(origin=dataset_url,
fname='flower_photos',
untar=True)
data_dir = pathlib.Path(data_dir)
print("The number of images in the dataset")
image_count = len(list(data_dir.glob('*/*.jpg')))
print(image_count)
print("Sample data in the dataset")
roses = list(data_dir.glob('roses/*'))
PIL.Image.open(str(roses[2]))
print("Some more sample data from the dataset")
roses = list(data_dir.glob('roses/*'))
PIL.Image.open(str(roses[4]))Code credit: https://www.tensorflow.org/tutorials/load_data/images
Output
The Tensorflow version is : 2.4.0 The dataset is being downloaded Downloading data from https://storage.googleapis.com/download.tensorflow.org/example_images/flower_photos.tgz 228818944/228813984 [==============================] - 4s 0us/step The number of images in the dataset 3670 Sample data in the dataset Some more sample data from the dataset
Explanation
- The required packages are downloaded.
- The version of Tensorflow is displayed on the console.
- The data is downloaded using the API.
- A sample of the image is also displayed on the console.
