['Same error here!\r\n'
 "Same here! My kaggle notebook stopped working like yesterday. It's strange because I have fixed version of datasets==1.1.2"
 "I'm looking at it right now"
 'I couldn\'t reproduce unfortunately. I tried\r\n```python\r\nfrom datasets import load_dataset\r\n\r\nload_dataset("cnn_dailymail", "3.0.0", download_mode="force_redownload")\r\n```\r\nand it worked fine on both my env (python 3.7.2) and colab (python 3.6.9)\r\n\r\nMaybe there was an issue with the google drive download link of the dataset ?\r\nAre you still having the issue ? If so could your give me more info about your python and requests version ?'
 "No, It's working fine now. Very strange. Here are my python and request versions\r\n\r\nrequests         2.24.0\r\nPython 3.8.2"
 "It's working as expected.  Closing the issue \r\n\r\nThanks everybody."]
