metric = metric_cls( TypeError: 'NoneType' object is not callable
Hi @klyuhang9,

I'm sorry but I can't reproduce your problem:
```python
In [2]: metric = load_metric('glue', 'rte')
Downloading builder script: 5.76kB [00:00, 2.40MB/s]
```

Could you please, retry to load the metric? Sometimes there are temporary connectivity issues.

Feel free to re-open this issue of the problem persists.
Hi, friend. I meet a problem.
When I run the code:
`metric = load_metric('glue', 'rte')`

There is a problem raising:
`metric = metric_cls(
TypeError: 'NoneType' object is not callable `

I don't know why. Thanks for your help!
