Got error when load cnn_dailymail dataset
Hi @jon-tow, thanks for reporting. And hi @dynamicwebpaige, thanks for your investigation. 

This issue was already reported 
- #3784

and its root cause is a change in the Google Drive service. See:
- #3786 

We have already fixed it. See:
- #3787 

We are planning to make a patch release today (indeed, we were planning to do it last Friday).

In the meantime, you can get this fix by installing our library from the GitHub master branch:
```shell
pip install git+https://github.com/huggingface/datasets#egg=datasets
```
Then, if you had previously tried to load the data and got the checksum error, you should force the redownload of the data (before the fix, you just downloaded and cached the virus scan warning page, instead of the data file):
```shell
load_dataset("...", download_mode="force_redownload")
```

When using datasets.load_dataset method to load cnn_dailymail dataset,  got error as below:

- windows os: FileNotFoundError: [WinError 3] 系统找不到指定的路径。: 'D:\\SourceCode\\DataScience\\HuggingFace\\Data\\downloads\\1bc05d24fa6dda2468e83a73cf6dc207226e01e3c48a507ea716dc0421da583b\\cnn\\stories'

The code is to load dataset:
windows os:
```
from datasets import load_dataset

dataset = load_dataset("cnn_dailymail", "3.0.0", cache_dir="D:\\SourceCode\\DataScience\\HuggingFace\\Data")

```
google colab:
```
import datasets

train_data = datasets.load_dataset("cnn_dailymail", "3.0.0", split="train")
```
