To load a big file in TensorFlow, you can use the module which provides a collection of classes and functions for easily creating complex input pipelines. Here is a general approach to loading a big file in TensorFlow:

  1. Create a dataset object using or depending on the type of data in the file.
dataset ="path/to/bigfile.txt")

  1. If needed, preprocess the data and parse the lines into tensors using the map method. You can use tf.strings.split to split a string into a tensor of strings and tf.strings.to_number to convert a string tensor to a numerical tensor.
dataset = x: tf.strings.to_number(tf.strings.split(x, ","), out_type=tf.float32))

  1. Shuffle, batch, and prefetch the dataset to optimize performance.
dataset = dataset.shuffle(buffer_size=1000)
dataset = dataset.batch(batch_size)
dataset = dataset.prefetch(

  1. Finally, create an iterator to iterate over the dataset and access the data in batches.
iterator = iter(dataset)
batch_data = next(iterator)

By using module, you can efficiently load and process large datasets in TensorFlow.
