No module named 'nlp.logging'
Thanks for reporting.

Apparently this is a versioning issue: the lib downloaded the `bleurt` script from the master branch where we did this change recently. We'll fix that in a new release this week or early next week. Cc @thomwolf 

Until that, I'd suggest you to download the right bleurt folder from github ([this one](https://github.com/huggingface/nlp/tree/0.4.0/metrics/bleurt)) and do

```python
from nlp import load_metric

bleurt = load_metric("path/to/bleurt/folder")
```

To download it you can either clone the repo or download the `bleurt.py` file and place it in a folder named `bleurt`  Actually we can fix this on our side, this script didn't had to be updated. I'll do it in a few minutes
Hi, I am using nlp version 0.4.0. Trying to use bleurt as an eval metric, however, the bleurt script imports nlp.logging which creates the following error. What am I missing?

```

```

Just to show once again that I can't import the logging module:

```
