Too much logging 

I'm doing this in the beginning of my script:

from datasets.utils import logging as datasets_logging
datasets_logging.set_verbosity_warning()

but I'm still getting these logs:

Hi ! Thanks for reporting :) 
I agree these one should be hidden when the logging level is warning, we'll fix that

+1, the amount of logging is excessive.

Most of it indeed comes from `filelock.py`, though there are occasionally messages from other sources too. Below is an example (all of these messages were logged after I already called `datasets.logging.set_verbosity_error()`)

```

So how to solve this problem?

In the latest version of the lib the logs about locks are at the DEBUG level so you won't see them by default.
Also `set_verbosity_warning` does take into account these logs now.
Can you try to update the lib ?
```
pip install --upgrade datasets
```

Thanks. For some reason I have to use the older version. Is that possible I can fix this by some surface-level trick?

I'm still using 1.13 version datasets.

On older versions you can use
```python
import logging

logging.getLogger("filelock").setLevel(logging.WARNING)
```

Whoa Thank you! It works!
