Once data preprocessing is complete and all features and labels are strictly numerical, the final data preparation step is converting these values into the native tensor format of a deep learning framework. This allows the dataset to be utilized in mathematical operations and model training.

The torch.tensor() function in PyTorch constructs a tensor from data such as a Python list or a NumPy array. When preparing datasets for neural networks, this function is used to load numerical features and target labels into PyTorch's native multidimensional array format.

In TensorFlow, the tf.constant() function creates a constant tensor from an array-like object, such as a NumPy array. During data preprocessing, this operation is commonly used to load numerical features and target values into TensorFlow's native format for model training.

tf.constant()

The to_numpy() method in pandas is used to convert a DataFrame into a NumPy array. By passing the dtype argument, such as dtype=float, you can ensure that all extracted numerical data is uniformly formatted as floating-point numbers. This is a common preprocessing step before loading tabular data into deep learning tensors.
