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.
The ‘tensorflow’ package can be installed on Windows using the below line of code −
pip install tensorflow
Tensor is a data structure used in TensorFlow. It helps connect edges in a flow diagram. This flow diagram is known as the ‘Data flow graph’. Tensors are nothing but a multidimensional array or a list.
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.
Example
Following is the code snippet −
print("1234 ---> ", int_vectorize_layer.get_vocabulary()[1289]) print("321 ---> ", int_vectorize_layer.get_vocabulary()[313]) print("Vocabulary size is : {}".format(len(int_vectorize_layer.get_vocabulary()))) print("The text vectorization is applied to the training dataset") binary_train_ds = raw_train_ds.map(binary_vectorize_text) print("The text vectorization is applied to the validation dataset") binary_val_ds = raw_val_ds.map(binary_vectorize_text) print("The text vectorization is applied to the test dataset") binary_test_ds = raw_test_ds.map(binary_vectorize_text) int_train_ds = raw_train_ds.map(int_vectorize_text) int_val_ds = raw_val_ds.map(int_vectorize_text) int_test_ds = raw_test_ds.map(int_vectorize_text)

Output
1234 ---> substring 321 ---> 20 Vocabulary size is : 10000 The text vectorization is applied to the training dataset The text vectorization is applied to the validation dataset The text vectorization is applied to the test dataset
Explanation
As a final preprocessing step, the ‘TextVectorization’ layer is applied on the training data, test data and validation dataset.
