Hi,

I am using the faiss feature from datasets which is very helpful and easy, except for there is a wired progress bar that I don’t know how to turn off.

The code I am using

```auto
datastore = datastore.add_faiss_index(column=self.knn_on, faiss_verbose=False)
            query = np.asarray(sample[self.knn_on])
            _scores, fewshots_examples = datastore.get_nearest_examples(
                index_name=self.knn_on,
                query=query,
                k=k,
            )

```

And the terminal will keep logging progress bar as the snapshot below:

I am wondering is there any way I can mute it?

Hmm… This?

I think it’s not from the map method but from either the add index or the find nearest method. Because it only show up when I include that logic and map has its own progress bar. Plus I want to keep the map’s tqdm while mute the 1/1 one. Is that possible

I think it’s possible, but without modifying the contents of the library, the only option is to manually silence tqdm temporarily like this… Or `add_faiss_index_from_external_arrays` for better tqdm?

Thanks for the answer.

I muted it by modifying the `add_vectors` method under the FaissIndex class

from

```auto
 for i in hf_tqdm(range(0, len(vectors), batch_size)): # Original

```

to

```auto
for i in hf_tqdm(range(0, len(vectors), batch_size), disable=(not faiss_verbose)): # disable 

```
