# The script performs the following steps:

# 1. Downloads the dataset from Hugging Face using the `load_dataset()` function.
# 2. Converts the Hugging Face dataset to a Pandas DataFrame for easier manipulation using the `to_pandas()` method.
# 3. Creates directories to save the dataset and images.
# 4. Filters out rows where image download fails by iterating through each row in the DataFrame, downloading the image using the custom `download_image()` function, and appending the filtered row to a new DataFrame called `filtered_rows`.
# 5. Creates a new DataFrame with the filtered rows and saves it to disk as a CSV file.
# 6. Prints a message indicating where the dataset and images have been saved.import os
