Streaming Dataset behind Proxy - FileNotFoundError
State: closed

### Describe the bug

When trying to stream a dataset i get the following error after a few minutes of waiting.

```
FileNotFoundError: https://huggingface.co/datasets/facebook/voxpopuli/resolve/main/data/n_files.json
If the repo is private or gated, make sure to log in with `huggingface-cli login`.
```

I have already set the proxy environment variables. Downloading a Dataset without streaming works as expected.
Still i suspect that this is connected to being behind a proxy.

Is there a way to set the proxy for streaming datasets? Possibly a keyword argument that gets passed to ffspec?

### Steps to reproduce the bug

This is the code i use.

```
import os
os.environ['http_proxy'] = "http://example.com:xxxx" 
os.environ['https_proxy'] = "http://example.com:xxxx" 


from datasets import load_dataset

ds = load_dataset("facebook/voxpopuli", name="de", streaming=True)
```

### Expected behavior

I would expect the streaming functionality to use the set proxy settings.

### Environment info

Filter unsupported extensions
State: closed

I used a regex to filter the data files based on their extension for packaged builders.

I tried and a regex is 10x faster that using `in` to check if the extension is in the list of supported extensions.

Supersedes https://github.com/huggingface/datasets/pull/5850

Close https://github.com/huggingface/datasets/issues/5849

I also did a small change to favor the parquet module in case of a draw in the extension counter.
Common Voice datasets still need `use_auth_token=True`
State: closed

### Describe the bug

We don't need to pass `use_auth_token=True` anymore to download gated datasets or models, so the following should work if correctly logged in.

```py
from datasets import load_dataset

load_dataset("mozilla-foundation/common_voice_6_1", "tr", split="train+validation")
```

However it throws an error - probably because something weird is hardcoded into the dataset loading script.

### Steps to reproduce the bug

1.) 
```
huggingface-cli login
```

2.) Make sure that you have accepted the license here:
https://huggingface.co/datasets/mozilla-foundation/common_voice_6_1

3.) Run:
```py
from datasets import load_dataset

load_dataset("mozilla-foundation/common_voice_6_1", "tr", split="train+validation")
```

4.)  You'll get:

    155 bundle_version = bundle_url_template.split("/")[0]

```

### Expected behavior

One should not have to pass `use_auth_token=True`. Also see discussion here: https://github.com/huggingface/blog/pull/1243#discussion_r1235131150

Config name / split name lost after map with multiproc
State: open

### Describe the bug

Performing a `.map` method on a dataset loses it's config name / split name only if run with multiproc

### Steps to reproduce the bug

```python
from datasets import Audio, load_dataset
from transformers import AutoFeatureExtractor
import numpy as np

# load dummy dataset
libri = load_dataset("hf-internal-testing/librispeech_asr_dummy", "clean")

# make train / test splits
libri = libri["validation"].train_test_split(seed=42, shuffle=True, test_size=0.1)

# example feature extractor
model_id = "ntu-spml/distilhubert"
feature_extractor = AutoFeatureExtractor.from_pretrained(model_id, do_normalize=True, return_attention_mask=True)

sampling_rate = feature_extractor.sampling_rate

libri = libri.cast_column("audio", Audio(sampling_rate=sampling_rate))

max_duration = 30.0

def preprocess_function(examples):
    audio_arrays = [x["array"] for x in examples["audio"]]
    inputs = feature_extractor(
        audio_arrays,
        sampling_rate=feature_extractor.sampling_rate,
        max_length=int(feature_extractor.sampling_rate * max_duration),
        truncation=True,
        return_attention_mask=True,
    )
    return inputs

# single proc map
libri_encoded = libri.map(
    preprocess_function, remove_columns=["audio", "file"], batched=True, num_proc=1
)

print(10 * "=" ,"Single processing", 10 * "=")
print("Config name before: ", libri["train"].config_name, " Split name before: ", libri["train"].split)
print("Config name after: ", libri_encoded["train"].config_name, " Split name after: ", libri_encoded["train"].split)

# multi proc map
libri_encoded = libri.map(
    preprocess_function, remove_columns=["audio", "file"], batched=True, num_proc=2
)

print(10 * "=" ,"Multi processing", 10 * "=")
print("Config name before: ", libri["train"].config_name, " Split name before: ", libri["train"].split)
print("Config name after: ", libri_encoded["train"].config_name, " Split name after: ", libri_encoded["train"].split)
```

**Print Output:**
```
========== Single processing ==========
Config name before:  clean  Split name before:  validation
Config name after:  clean  Split name after:  validation
========== Multi processing ==========
Config name before:  clean  Split name before:  validation
Config name after:  None  Split name after:  None
```

=> we can see that the config/split names are lost in the multiprocessing setting




### Expected behavior

Should retain both config / split names in the multiproc setting

Issue with train_test_split maintaining the same underlying PyArrow Table
State: open

### Describe the bug

I've been using the train_test_split method in the datasets module to split my HuggingFace Dataset into separate training, validation, and testing subsets. However, I've noticed an issue where the split datasets appear to maintain the same underlying PyArrow Table.

### Steps to reproduce the bug

1. Load any dataset  ```dataset = load_dataset("lhoestq/demo1")``` 
2. Try the next code:
```python
from datasets import Dataset, DatasetDict

train_size = 0.6

split_train = dataset["train"].train_test_split(
    train_size=train_size,
)

separate_dataset_dict = DatasetDict({
    "train": split_train["train"],
    "test": split_train["test"],
})
```
3.  The next code ```print(separate_dataset_dict)``` when printing the dataset it gives the indication that they have 3 and 2 rows respectively.
4. But the next code: 
 ```python
print(len(separate_dataset_dict["train"].data['id']))
print(len(separate_dataset_dict["test"].data['id'])) 
```

 Indicates that both tables still have 5 rows.

### Expected behavior

However, I've noticed that train_test_split["train"].data, test_val_split["train"].data, and test_val_split["test"].data are identical, suggesting that they all point to the same underlying PyArrow Table. This means that the split datasets are not independent, as I expected.

I believe this is a bug in the train_test_split implementation, as I would expect this function to return datasets with separate underlying PyArrow Tables. Could you please help me understand if this is expected behavior, or if there's a workaround to create truly independent split datasets?

I would appreciate any assistance with this issue. Thank you.

### Environment info

I tried in Colab:

IterableDataset: split by node and map may preprocess samples that will be skipped anyway
State: open

              There are two ways an iterable dataset can be split by node:
1. if the number of shards is a factor of number of GPUs: in that case the shards are evenly distributed per GPU
2. otherwise, each GPU iterate on the data and at the end keeps 1 sample out of n(GPUs) - skipping the others.

In case 2. it's therefore possible to have the same examples passed to `prepare_dataset` for each GPU.

This doesn't sound optimized though, because it runs the preprocessing on samples that won't be used in the end.

Could you open a new issue so that we can discuss about this and find a solution ?

read metric glue.py from local file 
State: closed

### Describe the bug

Currently, The server is off-line.  I am using the glue metric from the local file downloaded from the hub. 
I download / cached datasets using `load_dataset('glue','sst2', cache_dir='/xxx')` to cache them and then in the off-line mode, I use `load_dataset('xxx/glue.py','sst2', cache_dir='/xxx')`. I can successfully reuse cached datasets.

My problem is about the load_metric. 
When I run `load_dataset('xxx/glue_metric.py','sst2',cache_dir='/xxx')` , it returns 

`  File "xx/lib64/python3.9/site-packages/datasets/utils/deprecation_utils.py", line 46, in wrapper

Bad error message when trying to download gated dataset
State: closed

### Describe the bug

When I attempt to download a model from the Hub that is gated without being logged in, I get a nice error message. E.g.:

E.g.
```sh
Repository Not Found for url: https://huggingface.co/api/models/DeepFloyd/IF-I-XL-v1.0.
Please make sure you specified the correct `repo_id` and `repo_type`.
If you are trying to access a private or gated repo, make sure you are authenticated.
Invalid username or password..
Will try to load from local cache.
```

If I do the same for a gated dataset on the Hub, I'm not gated a nice error message IMO:

```sh
File ~/hf/lib/python3.10/site-packages/fsspec/implementations/http.py:430, in HTTPFileSystem._info(self, url, **kwargs)
    427     except Exception as exc:
    428         if policy == "get":
    429             # If get failed, then raise a FileNotFoundError
--> 430             raise FileNotFoundError(url) from exc
    431         logger.debug(str(exc))
    433 return {"name": url, "size": None, **info, "type": "file"}

FileNotFoundError: https://huggingface.co/datasets/mozilla-foundation/common_voice_13_0/resolve/main/n_shards.json
```

### Steps to reproduce the bug

```
huggingface-cli logout
```

and then:

```py
from datasets import load_dataset, Audio

# English
stream_data = load_dataset("mozilla-foundation/common_voice_13_0", "en", split="test", streaming=True)
stream_data = stream_data.cast_column("audio", Audio(sampling_rate=16000))
en_sample = next(iter(stream_data))["audio"]["array"]

# Swahili
stream_data = load_dataset("mozilla-foundation/common_voice_13_0", "sw", split="test", streaming=True)
stream_data = stream_data.cast_column("audio", Audio(sampling_rate=16000))
sw_sample = next(iter(stream_data))["audio"]["array"]
```

What is the Right way to use discofuse dataset??
State: closed

[Click here for Dataset link](https://huggingface.co/datasets/discofuse/viewer/discofuse-wikipedia/train?row=6)
**Below is the following way, as per my understanding , Is it correct :question: :question:**

The **columns/features from `DiscoFuse dataset`** that will be the **input to the `encoder` and `decoder`** are:

[Click here for Dataset link](https://huggingface.co/datasets/discofuse/viewer/discofuse-wikipedia/train?row=6)

1. **coherent_first_sentence**

2. **coherent_second_sentence**

3. **incoherent_first_sentence**

4. **incoherent_second_sentence**

[Click here for Dataset link](https://huggingface.co/datasets/discofuse/viewer/discofuse-wikipedia/train?row=6)

The **`encoder` will take these four columns as input and encode them into a sequence of hidden states. The `decoder` will then take these hidden states as input and decode them into a new sentence that fuses the two original sentences together.**

The **discourse type, connective_string, has_coref_type_pronoun, and has_coref_type_nominal columns will not be used as input to the encoder or decoder.** These columns are used to provide additional information about the dataset, but they are not necessary for the task of sentence fusion.

Please correct me if I am wrong; otherwise, if this understanding is right, how shall I implement this task practically?
Support for data with instance-wise dictionary as features
State: open
Labels: name: enhancement

### Feature request

I notice that when loading data instances with feature type of python dictionary, the dictionary keys would be broadcast so that every instance has the same set of keys. Please see an example in the Motivation section.

It is possible to avoid this behavior, i.e., load dictionary features as it is and do not broadcast the keys among instances? Please note that these dictionaries would have to be processed dynamically at each training iteration into strings (and tokenized).

### Motivation

I am trying to load a dataset from a json file. Each instance of the dataset has a feature that is a dictionary but its keys depend on the instance. Every two instances may have different keys. For example, imagine a dataset that contains a set of math expressions from a bunch of mutually redundant expressions:
```
{
    "index": 0,
    "feature": {
        "2 * x + y >= 3": ["2 * x + y >= 3", "4 * x + 2 * y >= 6"],
        ...
    }
},
...
{
    "index": 9999,
    "feature": {
        "x >= 6": ["x >= 6", "x >= 0", "x >= -1"],
        ...
    }
},
...
```
When directly loading the dataset using `data = load_dataset("json", data_files=file_paths, split='train')`, each instance would have all the keys from other instances and None as values. That is, instance of index 0 becomes:
```
{
    "index": 0,
    "feature": {
        "2 * x + y >= 3": ["2 * x + y >= 3", "4 * x + 2 * y >= 6"],
        ...
        "x >= 6": None,  # keys from other instances
        ...
    }
},
```
This is not desirable. Moreover, issue would be raised if I attempt to combine two such datasets using `data = concatenate_datasets(multi_datasets)`, perhaps because their dictionary features contain different keys.

A solution I can think of is to store the dictionary features as a long string, and evaluate it later. Please kindly suggest any other solution using existing methods of datasets.

Replace metadata utils with `huggingface_hub`'s RepoCard API
State: closed

Use `huggingface_hub`'s RepoCard API instead of `DatasetMetadata` for modifying the card's YAML, and deprecate `datasets.utils.metadata` and `datasets.utils.readme`.

After removing these modules, we can also delete `datasets.utils.resources` since the moon landing repo now stores its own version of these resources for the metadata UI.

PS: this change requires bumping `huggingface_hub` to 0.13.0 (Transformers requires 0.14.0, so should be ok)
Return the audio filename when decoding fails due to corrupt files
State: open
Labels: name: enhancement

### Feature request

Return the audio filename when the audio decoding fails. Although currently there are some checks for mp3 and opus formats with the library version there are still cases when the audio decoding could fail, eg. Corrupt file. 

### Motivation

When you try to load an object file dataset and the decoding fails you can't know which file is corrupt
```

raise LibsndfileError(err, prefix="Error opening {0!r}: ".format(self.name))
soundfile.LibsndfileError: Error opening <_io.BytesIO object at 0x7f5ab7e38290>: Format not recognised.
```

### Your contribution

Make a PR to Add exceptions for LIbsndfileError to return the audio filename or path when soundfile decoding fails.

Make get_from_cache use custom temp filename that is locked
State: closed

This PR ensures that the temporary filename created is the same as the one that is locked, while writing to the cache.

This PR stops using `tempfile` to generate the temporary filename.

Additionally, the behavior now is aligned for both `resume_download` `True` and `False`.

Refactor temp_file_manager so that it uses the filename that is locked: 
- Use: `cache_path + ".incomplete"`, when the locked one is `cache_path + ".lock"`

Before it was using `tempfile` inside `cache_dir`, which was not locked: although very improbable name collision (8 random characters), this was not impossible when huge number of multiple processes.

`datasets.map` not reusing cached copy by default
State: closed

### Describe the bug

When I load the dataset from local directory, it's cached copy is picked up after first time. However, for `map` operation, the operation is applied again and cached copy is not picked up. Is there any way to pick cached copy instead of processing it again? The only solution I could think of was to use `save_to_disk` after my last transform and then use that in my DataLoader pipeline. Are there any other solutions for the same?

One more thing, my dataset is occupying 6GB storage memory after I use `map`, is there any way I can reduce that memory usage?


### Steps to reproduce the bug

```
# make sure that dataset decodes audio with correct sampling rate
dataset_sampling_rate = next(iter(self.raw_datasets.values())).features["audio"].sampling_rate
if dataset_sampling_rate != self.feature_extractor.sampling_rate:
    self.raw_datasets = self.raw_datasets.cast_column(
        "audio", datasets.features.Audio(sampling_rate=self.feature_extractor.sampling_rate)
    )

vectorized_datasets = self.raw_datasets.map(
    self.prepare_dataset,
    remove_columns=next(iter(self.raw_datasets.values())).column_names,
    num_proc=self.num_workers,
    desc="preprocess datasets",
)
# filter data that is longer than max_input_length
self.vectorized_datasets = vectorized_datasets.filter(
    self.is_audio_in_length_range,
    num_proc=self.num_workers,
    input_columns=["input_length"],
        )

def prepare_dataset(self, batch):
    # load audio
    sample = batch["audio"]
    inputs = self.feature_extractor(sample["array"], sampling_rate=sample["sampling_rate"])
    batch["input_values"] = inputs.input_values[0]
    batch["input_length"] = len(batch["input_values"])

    batch["labels"] = self.tokenizer(batch["target_text"]).input_ids
    return batch

```

### Expected behavior

`map` to use cached copy and if possible an alternative technique to reduce memory usage after using `map`

### Environment info


- `datasets` version: 2.12.0

Importing PyTorch reduces multiprocessing performance for map
State: closed

### Describe the bug

I noticed that the performance of my dataset preprocessing with `map(...,num_proc=32)` decreases when PyTorch is imported.

### Steps to reproduce the bug

I created two example scripts to reproduce this behavior:

```
import datasets
datasets.disable_caching()

from datasets import Dataset
import time
    
PROC=32

if __name__ == "__main__":
    dataset = [True] * 10000000
    dataset = Dataset.from_dict({'train': dataset})
    

    start = time.time()
    dataset.map(lambda x: x, num_proc=PROC)
    end = time.time()
    print(end - start)
```
Takes around 4 seconds on my machine.

While the same code, but with an `import torch`:
```
import datasets
datasets.disable_caching()

from datasets import Dataset
import time
import torch
    
PROC=32

if __name__ == "__main__":
    dataset = [True] * 10000000
    dataset = Dataset.from_dict({'train': dataset})
    

    start = time.time()
    dataset.map(lambda x: x, num_proc=PROC)
    end = time.time()
    print(end - start)
```
takes around 22 seconds.



### Expected behavior

I would expect that the import of torch to not have such a significant effect on the performance of map using multiprocessing.


### Environment info

Breaking API change in datasets.list_datasets caused by change in HfApi.list_datasets
State: closed

### Describe the bug

Hi all,

after an update of the `datasets` library, we observer crashes in our code. We relied on `datasets.list_datasets` returning a `list`. Now, after the API of the HfApi.list_datasets was changed and it returns a `list` instead of an `Iterable`, the `datasets.list_datasets` now sometimes returns a `list` and somesimes an `Iterable`. 

It would be helpful to indicate that by the return type of the `datasets.list_datasets` function.

Thanks,
Martin 

### Steps to reproduce the bug

Here, the code crashed after we updated the `datasets` library:

```python
# list_datasets no longer returns a list, which leads to an error when one tries to slice it
for datasets.list_datasets(with_details=True)[:limit]:
    ...
```

### Expected behavior

It would be helpful to indicate that by the return type of the `datasets.list_datasets` function.

### Describe the bug

After loading an audio dataset, and looking at a sample entry, the `path` element, which is supposed to be the path to the audio file, doesn't actually exist.


### Steps to reproduce the bug

Run bug.py:

```py
import os.path

from datasets import load_dataset

def run() -> None:
    cv13 = load_dataset(
        "mozilla-foundation/common_voice_13_0",
        "hi",
        split="train",
    )

    print(cv13[0])
    audio_file = cv13[0]["path"]
    if not os.path.exists(audio_file):

Missing elements in `map` a batched dataset
State: closed

### Describe the bug

As outlined [here](https://discuss.huggingface.co/t/length-error-using-map-with-datasets/40969/3?u=sachin), the following collate function drops 5 out of possible 6 elements in the batch (it is 6 because out of the eight, two are bad links in laion). A reproducible [kaggle kernel ](https://www.kaggle.com/sachin/laion-hf-dataset/edit) can be found here.

The weirdest part is when inspecting the sizes of the tensors as shown below, both `tokenized_captions["input_ids"]` and `image_features` show the correct shapes. Simply the output only has one element (with the batch dimension squeezed out).

```python
class CollateFn:        
    def get_image(self, url):
        try:
            response = requests.get(url)
            return Image.open(io.BytesIO(response.content)).convert("RGB")
        except PIL.UnidentifiedImageError:
            logger.info(f"Reading error: Could not transform f{url}")
            return None
        except requests.exceptions.ConnectionError:
            logger.info(f"Connection error: Could not transform f{url}")
            return None
        
        
    def __call__(self, batch):
        images = [self.get_image(url) for url in batch["url"]]
        captions = [caption for caption, image in zip(batch["caption"], images) if image is not None]
        images = [image for image in images if image is not None]
        
        tokenized_captions = tokenizer(
            captions,
            padding="max_length",
            truncation=True,
            max_length=tokenizer.model_max_length,
            return_tensors="pt",
        )
        
        image_features = torch.stack([torch.Tensor(feature_extractor(image)["pixel_values"][0]) for image in images])
#         import pdb; pdb.set_trace()
        return {"input_ids": tokenized_captions["input_ids"], "images": image_features}

collate_fn = CollateFn()
laion_ds = datasets.load_dataset("laion/laion400m", split="train", streaming=True)
laion_ds_batched = laion_ds.map(collate_fn, batched=True, batch_size=8, remove_columns=next(iter(laion_ds)).keys())
```

### Steps to reproduce the bug

A reproducible [kaggle kernel ](https://www.kaggle.com/sachin/laion-hf-dataset/edit) can be found here.

### Expected behavior

Would expect `next(iter(laion_ds_batched))` to produce two tensors of shape `(batch_size, 77)` and `batch_size, image_shape`.

### Environment info

Cannot use both set_format and set_transform
State: closed

### Describe the bug

I need to process some data using the set_transform method but I also need the data to be formatted for pytorch before processing it.

I don't see anywhere in the documentation something that says that both methods cannot be used at the same time.

### Steps to reproduce the bug

```
from datasets import load_dataset
ds = load_dataset("mnist", split="train")
ds.set_format(type="torch")
def transform(entry):
    return entry["image"].double()
ds.set_transform(transform)

print(ds[0])
```

### Expected behavior

It should print the pytorch tensor image as a double, but it errors because "entry" in the transform function doesn't receive a pytorch tensor to begin with, it receives a PIL Image -> entry.double() errors because entry isn't a pytorch tensor.

### Environment info
Latest versions.


### Note:
It would be at least handy to have access to a function that can do the dataset.set_format in the set_transform function.

Something like:
```
from datasets import load_dataset, do_format
ds = load_dataset("mnist", split="train")
def transform(entry):
    entry = do_format(entry, type="torch")
    return entry["image"].double()
ds.set_transform(transform)

print(ds[0])
```

Unbearably slow sorting on big mapped datasets
State: open

### Describe the bug

For me, with ~40k lines, sorting took 3.5 seconds on a flattened dataset (including the flatten operation) and 22.7 seconds on a mapped dataset (right after sharding), which is about x5 slowdown. Moreover, it seems like it slows down exponentially with bigger datasets (wasn't able to sort 700k lines at all, with flattening takes about a minute).

### Steps to reproduce the bug

```Python
from datasets import load_dataset
import time

dataset = load_dataset("xnli", "en", split="train")

dataset = dataset.shard(10, 0)

print(len(dataset))

t = time.time()

# dataset = dataset.flatten_indices()  # uncomment this line and it's fast

dataset = dataset.sort("label", reverse=True, load_from_cache_file=False)

print(f"finished in {time.time() - t:.4f} seconds")

```

### Expected behavior

Expect sorting to take the same or less time than flattening and then sorting.

Offer an alternative to Iterable Dataset that allows lazy loading and processing while skipping batches efficiently
State: open
Labels: name: enhancement

### Feature request

I would like a way to resume training from a checkpoint without waiting for a very long time when using an iterable dataset.

### Motivation

I am training models on the speech-recognition task. I have very large datasets that I can't comfortably store on a disk and also quite computationally intensive audio processing to do. As a result I want to load data from my remote when it is needed and perform all processing on the fly.

I am currently using the iterable dataset feature of _datasets_. It does everything I need with one exception. My issue is that when resuming training at a step n, we have to download all the data and perform the processing of steps < n, just to get the iterable at the right step. In my case it takes almost as long as training for the same steps, which make resuming training from a checkpoint useless in practice.

I understand that the nature of iterators make it probably nearly impossible to quickly resume training.

I thought about a possible solution nonetheless : 

I could in fact index my large dataset and make it a mapped dataset. Then I could use set_transform to perform the processing on the fly. Finally, if I'm not mistaken, the _accelerate_ package allows to [skip steps efficiently](https://github.com/huggingface/accelerate/blob/a73898027a211c3f6dc4460351b0ec246aa824aa/src/accelerate/data_loader.py#L827) for a mapped dataset.

Is it possible to lazily load samples of a mapped dataset ? I'm used to [dataset scripts](https://huggingface.co/docs/datasets/dataset_script), maybe something can be done there.
If not, I could do it using a plain _Pytorch_ dataset. Then I would need to convert it to a _datasets_' dataset to get all the features of _datasets_. Is it something possible ?

### Your contribution

I could provide a PR to allow lazy loading of mapped dataset or the conversion of a mapped _Pytorch_ dataset into a _Datasets_ dataset if you think it is an useful new feature.

Relax `ci.yml` trigger for `pull_request` based on modified paths
State: open

## What's in this PR?

As of a previous PR at #5902, I've seen that the CI was automatically trigger on any file, in that case when modifying a Jupyter Notebook (.ipynb), which IMO could be skipped, as the modification on the Jupyter Notebook has no effect/impact on the `ci.yml` outcome. So this PR controls the paths that trigger the `ci.yml` to avoid wasting resources when not needed.

## What's pending in this PR?

I would like to confirm whether this should affect both `push` and `pull_request`, since just modifications in those files won't change the `ci.yml` outcome, so maybe it's worth skipping it too in the `push` trigger.
Fix `Overview.ipynb` & detach Jupyter Notebooks from `datasets` repository
State: closed

## What's in this PR?

This PR solves #5887 since there was a mismatch between the tokenizer and the model used, since the tokenizer was `bert-base-cased` while the model was `distilbert-base-case` both for the PyTorch and TensorFlow alternatives. Since DistilBERT doesn't use/need the `token_type_ids`, the `**batch` was failing, as the batch contained `input_ids`, `attention_mask`, `token_type_ids`, `start_positions` and `end_positions`, and `token_type_ids` was not required.

Besides that, at the end `seqeval` was being used to evaluate the model predictions, and just `evaluate` was being installed, so I've also included the `seqeval` installation.

Finally, I've re-run everything in Google Colab, and every cell was successfully executed!

## What was done on top of the original PR?

Based on the comments from @mariosasko and @stevhliu, I've updated the contents of this PR to also review the `quickstart.mdx` and update what was needed, besides that, we may eventually move the `Overview.ipynb` dataset to `huggingface/notebooks` following @stevhliu suggestions.
Make prepare_split more robust if errors in metadata dataset_info splits
State: closed

This PR uses `split_generator.split_info` as default value for `split_info` if any exception is raised while trying to get `split_generator.name` from `self.info.splits` (this may happen if there is any error in the metadata dataset_info splits).

Please note that `split_info` is only used by the logger.

Fix #5895 if passed `verification_mode="no_checks"`:
```python
ds = load_dataset(
    "ArmelR/stack-exchange-instruction", 
    data_dir="data/finetune", 
    split="train", 
    verification_mode="no_checks", 
    revision="c609f1caade5cfbf3b9fe9cfa17d7cb000b457bd",
