python-kerasHow do I reshape data in Python using Keras?

Reshaping data in Python using Keras is a common task for deep learning models. It involves changing the dimensions of the data for the model to be able to interpret it correctly. This can be done using the reshape() function of the Keras library.

Example

import numpy as np
from keras.layers import Input, Reshape

# Create the input data
data = np.array([[1,2,3,4,5,6,7,8,9]])

# Reshape the input data to the desired shape
reshaped_data = Reshape((3, 3))(data)

# Print the reshaped data
print(reshaped_data)

Output example

[[[1 2 3]
  [4 5 6]
  [7 8 9]]]

The code above consists of the following parts:

1. Importing the numpy and Keras libraries.
2. Creating the input data as a NumPy array.
3. Reshaping the data using the reshape() function.
4. Printing the reshaped data.
