[Staging] Update dataset repos automatically on the Hub
State: closed

Let's have a script that updates the dataset repositories on staging for now. This way we can make sure it works fine before going in prod.

Related to https://github.com/huggingface/datasets/issues/3341

The script runs on each commit on `master`. It checks the datasets that were changed, and it pushes the changes to the corresponding repositories on the Hub.

If there's a new dataset, then a new repository is created.

If the commit is a new release of `datasets`, it also pushes the tag to all the repositories.

Comments:
do keep us updated on how it's going in staging! cc @SBrandeis 

Sure ! For now it works smoothly. We'll also do a new release today.

I can send you some repos to explore on staging, in case you want to see how they look like after being updated.
For example [swahili_news](https://moon-staging.huggingface.co/datasets/swahili_news/tree/main)
Unexpected behavior doing Split + Filter
State: closed
Labels: description: Something isn't working
name: bug

## Describe the bug
I observed unexpected behavior when applying 'train_test_split' followed by 'filter' on dataset. Elements of the training dataset eventually end up in the test dataset (after applying the 'filter') 

## Steps to reproduce the bug
```
from datasets import Dataset
import pandas as pd
dic = {'x': [1,2,3,4,5,6,7,8,9], 'y':['q','w','e','r','t','y','u','i','o']}
df = pd.DataFrame.from_dict(dic)
dataset = Dataset.from_pandas(df)
split_dataset = dataset.train_test_split(test_size=0.5, shuffle=False, seed=42)
train_dataset = split_dataset["train"]
eval_dataset = split_dataset["test"]
eval_dataset_2 = eval_dataset.filter(lambda example: example['x'] % 2 == 0)
print( eval_dataset['x'])
print(eval_dataset_2['x'])
```
One observes that elements in eval_dataset2 are actually coming from the training dataset...

## Expected results
The expected results would be that the filtered eval dataset would only contain elements from the original eval dataset.

## Actual results
Specify the actual results or traceback.

## Environment info
<!-- You can run the command `datasets-cli env` and copy-and-paste its output below. -->
- `datasets` version: 1.12.1
- Platform: Windows 10
- Python version: 3.7
- PyArrow version: 5.0.0


Comments:
Hi ! This is an issue with `datasets` 1.12. Sorry for the inconvenience. Can you update to `>=1.13` ?
see https://github.com/huggingface/datasets/issues/3190

Maybe we should also backport the bug fix to `1.12` (in a new version `1.12.2`)
Add `__add__()`, `__iadd__()` and similar to `Dataset` class
State: closed
Labels: description: New feature or request
name: enhancement

description: Generic discussion on the library
name: generic discussion

**Is your feature request related to a problem? Please describe.**
No.

**Describe the solution you'd like**
I would like to be able to concatenate datasets as follows:
```python
>>> dataset["train"] += dataset["validation"]
```

... instead of using `concatenate_datasets()`:
```python
>>> raw_datasets["train"] = concatenate_datasets([raw_datasets["train"], raw_datasets["validation"]])
>>> del raw_datasets["validation"]
```

**Describe alternatives you've considered**
Well, I have considered `concatenate_datasets()` 😀

**Additional context**
N.a.


Comments:
I was going through the codebase, and I believe the implementation of __add__() and __iadd__() will be similar to concatenate_datasets() after the elimination of code for arguments other than the list of datasets (info, split, axis). 
(Assuming elimination of axis means concatenating over axis 1.)

Most data frame libraries (Polars, Pandas, etc.) override `__add__` to perform (mathematical) summation, so having different behavior could lead to confusion.
JSONDecodeError with HuggingFace dataset viewer

## Dataset viewer issue for 'pubmed_neg'

**Link:** https://huggingface.co/datasets/IGESML/pubmed_neg

I am getting the error: 
Status code:   400
Exception:     JSONDecodeError
Message:       Expecting property name enclosed in double quotes: line 61 column 2 (char 1202)

I have checked all files - I am not using single quotes anywhere. Not sure what is causing this issue.

Am I the one who added this dataset ? Yes


Comments:
Hi ! I think the issue comes from the dataset_infos.json file: it has the "flat" field twice.

Can you try deleting this file and regenerating it please ?

Thanks! That fixed that, but now I am getting:
Server Error
Status code:   400
Exception:     KeyError
Message:       'feature'

I checked the dataset_infos.json and pubmed_neg.py script, I don't use 'feature' anywhere as a key. Is the dataset viewer expecting that I do?

It seems that the `feature` key is missing from some feature type definition in your dataset_infos.json:
```json
			"tokens": {
				"dtype": "list",
				"id": null,
				"_type": "Sequence"
			},
			"tags": {
				"dtype": "list",
				"id": null,
				"_type": "Sequence"
			}
```
They should be
```json
			"tokens": {
				"dtype": "list",
				"id": null,
				"_type": "Sequence"
                                 "feature": {"dtype": "string", "id": null, "_type": "Value"}
			},
			"tags": {
				"dtype": "list",
				"id": null,
				"_type": "Sequence",
                                 "feature": {"num_classes": 5, "names": ["-", "S", "H", "N", "C"], "names_file": null, "id": null, "_type": "ClassLabel"}
			}
```

Note that you can generate the dataset_infos.json automatically to avoid mistakes:
```bash
datasets-cli test ./path/to/dataset --save_infos
```
Remove redundant local path information in audio/image datasets

Remove the redundant path information in the audio/image dataset as discussed in https://github.com/huggingface/datasets/pull/3430#issuecomment-994734828

TODOs:
* [ ] merge https://github.com/huggingface/datasets/pull/3430
* [ ] merge https://github.com/huggingface/datasets/pull/3364
* [ ] re-generate the info files of the updated audio datasets

cc:  @patrickvonplaten @anton-l @nateraw (I expect this to break the audio/vision examples in Transformers; after this change you'll be able to access underlying paths as follows `dset = dset.cast_column("audio", Audio(..., decode=False)); path = dset[0]["audio"]`)


Comments:
Cool, I'm in favor of this PR. Our official examples in speech already make use of `"audio"` so no need to change anything there. It would be great if we could prominently feature how one can get the audio path without decoding in the docs.

@patrickvonplaten Yes, I agree.

cc @stevhliu we should add an example where decoding is disabled (to read paths) to  [this section](https://github.com/huggingface/datasets/blob/master/docs/source/audio_process.rst#audio-datasets) in the docs and remove the mentions of `path`/`file` (if we merge this PR).

Thanks @mariosasko. Are you planning to finish this before we remove the dataset scripts from GitHub?

Comments:
Hi ! `load_dataset` accepts as input either a local dataset directory or a dataset name from the Hugging Face Hub.

So here you are getting this error the second time because it tries to load the local `wiki_dpr` directory, instead of `wiki_dpr` from the Hub. It doesn't work since it's a **cache** directory, not a **dataset** directory in itself.

To fix that you can use another cache directory like `cache_dir="/data2/whr/lzy/open_domain_data/retrieval/cache"`

thx a lot
Make cast cacheable (again) on Windows
State: closed

`cast` currently emits the following warning when called on Windows:
```
Parameter 'function'=<function Dataset.cast.<locals>.<lambda> at 0x000001C930571EA0> of the transform datasets.arrow_dataset.Dataset._map_single couldn't be hashed properly, a random hash was used instead. Make sure your transforms and parameters are serializable with pickle or dill for the dataset fingerprinting 
and caching to work. If you reuse this transform, the caching mechanism will consider it to be different 
from the previous calls and recompute everything. This warning is only showed once. Subsequent hashing failures won't be showed.
```

It seems like the issue stems from the `config.PYARROW_VERSION` object not being serializable on Windows (tested with `dumps(lambda: config.PYARROW_VERSION)`), so I'm fixing this by capturing `config.PYARROW_VERSION.major` before the lambda definition.

## Expected results

## Environment info

- `datasets` version: 1.16.1
- Platform: Linux-5.11.0-1022-aws-x86_64-with-glibc2.31
- Python version: 3.9.6
- PyArrow version: 4.0.1

Comments:
maybe related to https://github.com/huggingface/datasets/issues/2859


It looks like it's currently calling `HfFileSystem.ls()` ~8 times at the root and for each subdirectory:
- ""
- "en.noblocklist"
- "en.noclean"
- "en"
- "multilingual"
- "realnewslike"

Currently `ls` is slow because it iterates on all the files inside the repository.

An easy optimization would be to cache the result of each call to `ls`.
We can also optimize `ls` by using a tree structure per directory instead of a list of all the files.

Adding mMARCO (v1.1) to HF datasets.

Hi @albertvillanova we've made a major overhaul of the loading script including all configurations we're making available. Could you please review it again?

@albertvillanova :ping_pong: 

Thanks @lhbonifacio for adding this dataset.
Hi there, i got an error about mmarco:
ConnectionError: Couldn't reach 'unicamp-dl/mmarco' on the Hub (ConnectionError)

Any help will be appreciated!

Hi @catqaq, we updated the loading script. Now you can load the datasets with:

```python
dataset = load_dataset('unicamp-dl/mmarco', 'portuguese')
```

You can check the list of supported languages and usage examples in [this link](https://huggingface.co/datasets/unicamp-dl/mmarco). Feel free to contact us if you have any issues.

Thanks for your quick updates. So, how can i get the fixed version, install from the source? It seems that the merging is blocked.

@catqaq you can load mMARCO using the namespace `unicamp-dl/mmarco` while this PR remains under review.

Thanks for your contribution, @lhbonifacio and  @hugoabonizio. And sorry for the late response.

We are removing the dataset scripts from this GitHub repo and moving them to the Hugging Face Hub: https://huggingface.co/datasets

As you already created this dataset under your organization namespace (https://huggingface.co/datasets/unicamp-dl/mmarco), I think we can safely close this PR.

We would suggest you complete your dataset card with the YAML tags, to make it searchable and discoverable.

Please, feel free to tell us if you need some help.

Fix type of bridge field in QED
State: closed

Use `Value("string")` instead of `Value("bool")` for the feature type of the `"bridge"` field in the QED dataset. If the value is `False`, set to `None`.

The following paragraph in the QED repo explains the purpose of this field:
>Each annotation in referential_equalities is a pair of spans, the question_reference and the sentence_reference, corresponding to an entity mention in the question and the selected_sentence respectively. As described in the paper, sentence_references can be "bridged in", in which case they do not correspond with any actual span in the selected_sentence. Hence, sentence_reference spans contain an additional field, bridge, which is a prepositional phrase when a reference is bridged, and is False otherwise. Prepositional phrases serve to link bridged references to an anchoring phrase in the selected_sentence. In the case a sentence_reference is bridged, the start and end, as well as the span string, map to such an anchoring phrase in the selected_sentence.

Comments:
I think it might come from two different issues:
1. Google Drive is an unreliable host, mainly because of quota limitations
2. the staging environment can sometimes raise some errors

For Google Drive tests we could set up some retries with backup URLs if necessary I guess.
For staging on the other hand, I guess we can investigate what causes this and discuss with the back-end team
