Is there any remedy to solve the connection issue ?

Comments:
Hi,

Did you try to run the code multiple times (GitHub URLs can be down sometimes for various reasons)? I can access `https://raw.githubusercontent.com/huggingface/datasets/1.11.0/metrics/rouge/rouge.py`, so this code is working without an error on my side. 

Additionally, can you please run the `datasets-cli env` command because it seems to me that you are using the `datasets` version different from `1.12.1`?

Same issue when running `metric = datasets.load_metric("accuracy")`.
Error info is:
```
metric = datasets.load_metric("accuracy")
Traceback (most recent call last):

  File "<ipython-input-2-d25db38b26c5>", line 1, in <module>
    metric = datasets.load_metric("accuracy")

  File "D:\anaconda3\lib\site-packages\datasets\load.py", line 610, in load_metric
    module_path, _ = prepare_module(

  File "D:\anaconda3\lib\site-packages\datasets\load.py", line 330, in prepare_module
    local_path = cached_path(file_path, download_config=download_config)

  File "D:\anaconda3\lib\site-packages\datasets\utils\file_utils.py", line 288, in cached_path
    output_path = get_from_cache(

  File "D:\anaconda3\lib\site-packages\datasets\utils\file_utils.py", line 605, in get_from_cache
    raise ConnectionError("Couldn't reach {}".format(url))
ConnectionError: Couldn't reach https://raw.githubusercontent.com/huggingface/datasets/1.11.0/metrics/accuracy/accuracy.py
```


 My `datasets-cli env` result is as follows:
- `datasets` version: 1.11.0
- Platform: Windows-10-10.0.19041-SP0
- Python version: 3.8.8
- PyArrow version: 6.0.0

@yananchen1989 did you find a way to solve this?

It seems to be able to solve this issue by adding the equivalent `accuracy.py` locally. 
change `metric = datasets.load_metric("accuracy")` to  `metric = datasets.load_metric(path = "./accuracy.py")`.
Copy `accuracy.py` from browser at [accuracy.py](https://raw.githubusercontent.com/huggingface/datasets/1.11.0/metrics/accuracy/accuracy.py)

This is really a good way
