AttributeError: module 'tensorflow._api.v2.train' has no attribute 'string_input_producer'

`_input_producer` is not available in TensorFlow 2.x as it was removed in version 2.0. Instead, you can use `tf.data.Dataset.from_tensor_slices` to create a dataset from the input data and then use the `map` function to preprocess the data. Here is an example:

import tensorflow as tf

# Input data
data = ["hello", "world", "tensorflow"]

# Create a dataset from the input data
dataset = tf.data.Dataset.from_tensor_slices(data)

# Define a function to preprocess the data
def preprocess_data(data):
    # Do some preprocessing here
    return data

# Map the function to the dataset
dataset = dataset.map(preprocess_data)

# Iterate over the dataset
for data in dataset:
    print(data)

In this example, `from_tensor_slices` creates a dataset from the input data. The `map` function applies the `preprocess_data` function to each element in the dataset. Finally, we iterate over the dataset to print the preprocessed data.
