Not Able to Download the Dataset

[Manasa-N-2504]

If I try downloading the dataset using the URL it shows Internal Server Error

dataset_path = stow.join('Datasets', 'IAM_Words') if not stow.exists(dataset_path): download_and_unzip('https://git.io/J0fjL', extract_to='Datasets')

file = tarfile.open(stow.join(dataset_path, "words.tgz"))
file.extractall(stow.join(dataset_path, "words"))

This segment of code also shows error
