(Load dataset failure) ConnectionError: Couldn’t reach https://raw.githubusercontent.com/huggingface/datasets/1.1.2/datasets/cnn_dailymail/cnn_dailymail.py
Are you running the script on a machine with an internet connection ? Yes ,  I can browse the url through Google Chrome. Does this HEAD request return 200 on your machine ?
```python
import requests                                                                                                                                                                                                         
requests.head("https://raw.githubusercontent.com/huggingface/datasets/1.1.2/datasets/cnn_dailymail/cnn_dailymail.py")
```

If it returns 200, could you try again to load the dataset ? Thank you very much for your response.
When I run 
``` 
import requests                                                                                                                                                                                                         
requests.head("https://raw.githubusercontent.com/huggingface/datasets/1.1.2/datasets/cnn_dailymail/cnn_dailymail.py")
```
It returns 200.

And I try again to load the dataset. I got the following errors again.

Connection error happened but the url was different.

I add the following code.
```
requests.head("https://drive.google.com/uc?export=download&id=0BwmD_VLjROrfTHk4NFg2SndKcjQ")
```
This  didn't  return 200
It returned like this:

For me 
```python
requests.head("https://drive.google.com/uc?export=download&id=0BwmD_VLjROrfTHk4NFg2SndKcjQ")
```
returns 200 I can browse the google drive through google chrome. It's weird. I can download the dataset through google drive manually. Could you try to update `requests` maybe ?
It works with 2.23.0 on my side My ```requests``` is 2.24.0 . It still can't return 200. Is it possible I download the dataset manually from google drive and use it for further test ? How can I do this ? I want to reproduce the model in this link https://huggingface.co/patrickvonplaten/bert2bert-cnn_dailymail-fp16. But I can't download the dataset through load_dataset method . I have tried many times  and the connection error always happens .
 The head request should definitely work, not sure what's going on on your side.
If you find a way to make it work, please post it here since other users might encounter the same issue.

If you don't manage to fix it you can use `load_dataset` on google colab and then save it using `dataset.save_to_disk("path/to/dataset")`.
Then you can download the directory on your machine and do
```python
from datasets import load_from_disk
dataset = load_from_disk("path/to/local/dataset")
``` Hi
I want to know if this problem has been solved because I encountered a similar issue. Thanks.
`train_data = datasets.load_dataset("xsum", `split="train")`
`ConnectionError:` Couldn't reach https://raw.githubusercontent.com/huggingface/datasets/1.1.3/datasets/xsum/xsum.py` Hi @smile0925 ! Do you have an internet connection ? Are you using some kind of proxy that may block the access to this file ?

Otherwise you can try to update `datasets` since we introduced retries for http requests in the 1.2.0 version
```
pip install --upgrade datasets
```
Let me know if that helps. Hi @lhoestq 
Oh, may be you are right. I find that my server uses some kind of proxy that block the access to this file.

I have the same problem, have you solved it? Many thanks Hi  @ZhengxiangShi 
You can first try whether your network can access these files. I need to use VPN to access these files, so I download the files that cannot be accessed to the local in advance, and then use them in the code. Like this,
`train_data = datasets.load_dataset("xsum.py", split="train")` For Ubuntu 20.04, there are the following feedback. 

Google Drive is ok, but raw.githubusercontent.com has a big problem.  It seems that the raw github could not match the common urllib3 protocols.

```

requests.head("https://drive.google.com/uc?export=download&id=0BwmD_VLjROrfTHk4NFg2SndKcjQ")

### The  following snippet could not solve the implicit ssl error.

```
import ssl

try:
    _create_unverified_https_context = ssl._create_unverified_context
except AttributeError:
    pass
else:
    ssl._create_default_https_context = _create_unverified_https_context
```

 Only the oldest versions of `datasets` use raw.githubusercontent.com. Can you try updating `datasets` ? Thank lhoestq fo the quick response. 

I solve the big issue with the command line as follows. 

**1. Open hosts (Ubuntu 20.04)**

`$ sudo gedit /etc/hosts`

**2. Add the command line into the hosts**

`151.101.0.133   raw.githubusercontent.com`

**3. Save hosts**

And then the jupyter notebook can access to the datasets (module)  and get the datasets of XSUM with raw.githubusercontent.com. 

So it is not users' fault. But most of the suggestions in the web are wrong. Anyway, I solve the problem finally. 

By the way, users need to add the other github commnads such as the following. 

`199.232.69.194 github.global.ssl.fastly.net`

Cheers!!!

Hey, I want to load the cnn-dailymail dataset for fine-tune.
I write the code like this
from datasets import load_dataset

test_dataset = load_dataset(“cnn_dailymail”, “3.0.0”, split=“train”)

And I got the following errors.
