How can Keras be used to download and explore the dataset associated with predicting tag for a stackoverflow question in Python?

Tensorflow is a machine learning framework that is provided by Google. It is an open-source framework used in conjunction with Python to implement algorithms, deep learning applications, and much more. It is used in research and for production purposes. It has optimization techniques that help in performing complicated mathematical operations quickly.

This is because it uses NumPy and multi-dimensional arrays. These multi-dimensional arrays are also known as ‘tensors’. The framework supports working with deep neural networks. It is highly scalable and comes with many popular datasets. It uses GPU computation and automates the management of resources. It comes with multitude of machine learning libraries and is well-supported and documented. The framework has the ability to run deep neural network models, train them, and create applications that predict relevant characteristics of the respective datasets.

The ‘tensorflow’ package can be installed on Windows using the below line of code −

pip install tensorflow

Keras was developed as a part of the research for the project ONEIROS (Open-ended Neuro-Electronic Intelligent Robot Operating System). Keras is a deep learning API, which is written in Python. It is a high-level API that has a productive interface that helps solve machine learning problems. It is highly scalable and comes with cross-platform abilities. This means Keras can be run on TPU or clusters of GPUs. Keras models can also be exported to run in a web browser or a mobile phone as well.

Keras is already present within the Tensorflow package. It can be accessed using the below line of code.

import tensorflow
from tensorflow import keras

We are using 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. Following is the code snippet to explore the dataset associated with predicting tag for a StackOverflow question in Python −

Example

print("Downloading tensorflow-text")
!pip -q install tensorflow-text

import collections
import pathlib
import re
import string
import tensorflow as tf

from tensorflow.keras import layers
from tensorflow.keras import losses
from tensorflow.keras import preprocessing
from tensorflow.keras import utils
from tensorflow.keras.layers.experimental.preprocessing import TextVectorization

import tensorflow_datasets as tfds
import tensorflow_text as tf_text
data_url =
'https://storage.googleapis.com/download.tensorflow.org/data/stack_overflow_16k.tar.gz'
dataset = utils.get_file(
   'stack_overflow_16k.tar.gz',
   data_url,
   untar=True,
   cache_dir='stack_overflow',
   cache_subdir='')
dataset_dir = pathlib.Path(dataset).parent
