Issue: Dataset with loading script does not work in renamed repos
State: open
Author: BramVanroy

### Describe the bug

My data repository was first called `BramVanroy/hplt-mono-v1-2` but I then renamed to use underscores instead of dashes. However, it seems that `datasets` retrieves the old repo name when it checks whether the repo contains data loading scripts in this line.

https://github.com/huggingface/datasets/blob/6fb6c834f008996c994b0a86c3808d0a33d44525/src/datasets/load.py#L1845

When I print `filename` it returns `hplt-mono-v1-2.py` but the files in the repo are of course `['.gitattributes', 'README.md', 'hplt_mono_v1_2.py']`. So the `filename` is the original reponame instead of the renamed one.

I am not sure if this is a caching issue or not or how I can resolve it.

### Steps to reproduce the bug

```
from datasets import load_dataset


ds = load_dataset(
    "BramVanroy/hplt-mono-v1-2",
    "ky",
    trust_remote_code=True
)
```

### Expected behavior

That the most recent repo name is used when `filename` is generated.

### Environment info

- `datasets` version: 2.16.1
- Platform: Linux-5.14.0-284.25.1.el9_2.x86_64-x86_64-with-glibc2.34

# Loading Dataset from Local Files Using 🤗Hugging Face.

To load a dataset from local files using the Hugging Face datasets library, you can use the `load_dataset` function.

```
from datasets import load_dataset
dataset = load_dataset('csv', data_files={'train': 'path/to/train.csv',
                                         'test': 'path/to/test.csv'})

Issue: Is there any way to solve hanging of IterableDataset using split by node + filtering during inference
State: open
Author: ssharpe42

### Describe the bug

I am using an iterable dataset in a multi-node setup, trying to do training/inference while filtering the data on the fly. I usually do not use `split_dataset_by_node` but it is very slow using the IterableDatasetShard in `accelerate` and `transformers`. When I filter after applying `split_dataset_by_node`, it results in shards that are not equal sizes due to unequal samples filtered from each one. 

The distributed process hangs when trying to accomplish this. Is there any way to resolve this or is it impossible to implement?



### Steps to reproduce the bug

Here is a toy example of what I am trying to do that reproduces the behavior

```
# torchrun --nproc-per-node 2 file.py


import os

import pandas as pd
import torch
from accelerate import Accelerator
from datasets import Features, Value, load_dataset
from datasets.distributed import split_dataset_by_node
from torch.utils.data import DataLoader

accelerator = Accelerator(device_placement=True, dispatch_batches=False)
if accelerator.is_main_process:
    if not os.path.exists("scratch_data"):
        os.mkdir("scratch_data")

    n_shards = 4
    for i in range(n_shards):
        df = pd.DataFrame({"id": list(range(10 * i, 10 * (i + 1)))})
        df.to_parquet(f"scratch_data/shard_{i}.parquet")


world_size = accelerator.num_processes
local_rank = accelerator.process_index


def collate_fn(examples):
    input_ids = []
    for example in examples:
        input_ids.append(example["id"])
    return torch.LongTensor(input_ids)


dataset = load_dataset(
    "parquet", data_dir="scratch_data", split="train", streaming=True
)
dataset = (
    split_dataset_by_node(dataset, rank=local_rank, world_size=world_size)
    .filter(lambda x: x["id"] < 35)
    .shuffle(seed=42, buffer_size=100)
)

batch_size = 2
train_dataloader = DataLoader(
    dataset,
    batch_size=batch_size,
    collate_fn=collate_fn,
    num_workers=2
)  

for x in train_dataloader:
    x = x.to(accelerator.device)
    print({"rank": local_rank, "id": x})
   
    y = accelerator.gather_for_metrics(x)
    if accelerator.is_main_process:
        print("gathered", y)


```

### Expected behavior

Is there any way to continue training/inference on the GPUs that have remaining data left without waiting for the others? Is it impossible to filter when

Issue: Non-deterministic `Dataset.builder_name` value
State: closed
Author: harupy

### Describe the bug

I'm not sure if this is a bug, but `print(ds.builder_name)` in the following code sometimes prints out `rotten_tomatoes` instead of `parquet`:

```python
import datasets

for _ in range(100):
    ds = datasets.load_dataset("rotten_tomatoes", split="train")
    print(ds.builder_name)  # prints out "rotten_tomatoes" sometimes instead of "parquet"
```

Output:

```
...
parquet
parquet
parquet
rotten_tomatoes
parquet
parquet
parquet
...
```

Here's a reproduction using GitHub Actions:
https://github.com/mlflow/mlflow/actions/runs/8153247984/job/22284263613?pr=11329#step:12:241

One of our tests is flaky because `builder_name` is not deterministic.

### Steps to reproduce the bug

1. Run the code above.

### Expected behavior

Always prints out `parquet`?

### Environment info

```
Copy-and-paste the text below in your GitHub issue.
- `datasets` version: 2.18.0
- Platform: Linux-6.5.0-1015-azure-x86_64-with-glibc2.34
- Python version: 3.8.18
- `huggingface_hub` version: 0.21.3
- PyArrow version: 15.0.0
- Pandas version: 2.0.3
- `fsspec` version: 2024.2.0
```

Comments:
When `rotten_tomatoes` is printed out, the following warning message is also printed out:

```
You can avoid this message in future by passing the argument `trust_remote_code=True`.
Passing `trust_remote_code=True` will be mandatory to load this dataset from the next major release of `datasets`.
```

Hi ! This behavior happens because the dataset was originakky created using a dataset script [rotten_tomatoes.py](https://huggingface.co/datasets/rotten_tomatoes/blob/26f40d324d7b281d8b3fb1c47f30f8b9957f206b/rotten_tomatoes.py) and because we added features recently allowing to download the dataset directly from Parquet files (parquet builder) without running the dataset script (rotten_tomatoes). The flakiness must come from the availability of the Parquet files (we automatically export them in the refs/convert/parquet branch and we recently had to move some files).

Anyway the easy fix on our side is to remove the dataset script completely, let me open a PR at https://huggingface.co/datasets/rotten_tomatoes

EDIT: opened https://huggingface.co/datasets/rotten_tomatoes/discussions/6, feel free to comment there if you're ok with that change

@lhoestq Thanks for the comment, explanation, and patch!

> we automatically export them in the refs/convert/parquet branch

When this operation is in progress, the parquet files become temporarily unavailable?

> When this operation is in progress, the parquet files become temporarily unavailable?

Yes correct. I just merged the patch btw :)

@lhoestq Thanks for merging the PR! I think this issue can be closed.
Issue: Push samples to dataset on hub without having the dataset locally
State: closed
Author: jbdel

### Feature request

Say I have the following code:

```
from datasets import Dataset
import pandas as pd
new_data = {
    "column_1": ["value1", "value2"],
    "column_2": ["value3", "value4"],
}
df_new = pd.DataFrame(new_data)
dataset_new = Dataset.from_pandas(df_new)
# add these samples to a remote dataset
```
It would be great to have a way to push dataset_new to a remote dataset that respects the same schema. This way one would not have to do the following:
```
from datasets import load_dataset
dataset = load_dataset('username/dataset_name', use_auth_token='your_hf_token_here')
updated_dataset = dataset['train'].concatenate(dataset_new)
updated_dataset.push_to_hub('username/dataset_name', use_auth_token='your_hf_token_here')
```





### Motivation

No need to download the dataset.

### Your contribution

Maybe this feature already exists, didnt see it though. I do not have the expertise to do this.

Comments:
Hi ! For now I would recommend creating a new Parquet file using `dataset_new.to_parquet()` and upload it to HF using `huggingface_hub` every time you get a new batch of data. You can name the Parquet files `0000.parquet`, `0001.parquet`, etc.

Though maybe make sure to not upload one file per sample since that would be inefficient. You can buffer your data and upload when you have enough new samples for example

This is excellent, thanks!
Issue: remove_columns is not in-place but the doc shows it is in-place
State: closed
Author: shelfofclub

### Describe the bug

The doc of `datasets` v2.17.0/v2.17.1 shows that `remove_columns` is in-place. [link](https://huggingface.co/docs/datasets/v2.17.1/en/package_reference/main_classes#datasets.DatasetDict.remove_columns)

In the text classification example of transformers v4.38.1, the columns are not removed.
https://github.com/huggingface/transformers/blob/a0857740c0e6127485c11476650314df3accc2b6/examples/pytorch/text-classification/run_classification.py#L421

### Steps to reproduce the bug

### Expected behavior

Actually remove the columns.

### Environment info

1. datasets v2.17.0
2. transformers v4.38.1

Comments:
Good catch! I've opened a PR with a fix in the `transformers` repo.

@mariosasko Thanks!

Will the doc of `datasets` be updated?

I find some possible mistakes in doc about whether `remove_columns` is in-place.
1. [You can also remove a column using map() with remove_columns but the present method is in-place (doesn’t copy the data to a new dataset) and is thus faster.](https://huggingface.co/docs/datasets/v2.17.1/en/package_reference/main_classes#datasets.Dataset.remove_columns)
2. [You can also remove a column using Dataset.map() with remove_columns but the present method is in-place (doesn’t copy the data to a new dataset) and is thus faster.](https://huggingface.co/docs/datasets/v2.17.1/en/package_reference/main_classes#datasets.DatasetDict.remove_columns)
3. [🤗 Datasets also has a remove_columns() function which is faster because it doesn’t copy the data of the remaining columns.](https://huggingface.co/docs/datasets/v2.17.1/en/process#map)

I've linked a PR that will fix the usage in the `datasets` docs.

Explicit is better than implicit, so this isn't a good enough reason. 

Thanks for the effort nonetheless :)!

Issue: load_dataset() does not support tsv

### Feature request

the load_dataset() for local functions support file types like csv, json etc but not of type tsv (tab separated values).

### Motivation

cant easily load files of type tsv, have to convert them to another type like csv then load

Comments:
#self-assign

Hi @dipsivenkatesh,

Please note that this functionality is already implemented. Our CSV builder uses `pandas.read_csv` under the hood, and you can pass the parameter `delimiter="\t"` to read TSV files.

Issue: Question: Is there any way for uploading a large image dataset?

)
dataset = dataset.cast_column("images", Sequence(Image()))
dataset.push_to_hub("StanfordAIMI/custom_dataset", max_shard_size="1GB")
```
where it takes a long time in the `Map` process. Do you think I can use multi-processing to map all the image data to the memory first? For the `Map()` function, I can set `num_proc`. But for `push_to_hub` and `cast_column`, I can not find it.

Thanks in advance!

Issue: Can't Read List of JSON Files Properly
State: open
Author: lordsoffallen

### Describe the bug

Trying to read a bunch of JSON files into Dataset class but default approach doesn't work. I don't get why it works when I read it one by one but not when I pass as a list :man_shrugging: 

The code fails with 

```
ArrowInvalid: JSON parse error: Invalid value. in row 0  
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x80 in position 0: invalid start byte 
DatasetGenerationError: An error occurred while generating the dataset
```

### Steps to reproduce the bug

This doesn't work

```
from datasets import Dataset

# dir contains 100 json files.
Dataset.from_json("/PUT SOME PATH HERE/*")
```

This works:
```
from datasets import concatenate_datasets

ls_ds = []

for file in list_of_json_files:
    ls_ds.append(Dataset.from_json(file))

ds = concatenate_datasets(ls_ds)

```





### Expected behavior

I expect this to read json files properly as error is not clear

### Environment info

- `datasets` version: 2.17.0
- Platform: Linux-6.5.0-15-generic-x86_64-with-glibc2.35
- Python version: 3.10.13
- `huggingface_hub` version: 0.20.2
- PyArrow version: 15.0.0
- Pandas version: 2.2.0
- `fsspec` version: 2023.10.0


Comments:
Found the issue, if there are other files in the directory, it gets caught into this `*` so essentially it should be `*.json`. Could we possibly to check for list of files to make sure the pattern matches json files and raise error if not?

I don't think we should filter for `*.json` as this might silently remove desired files for many users. And this could be a major breaking change for many organizations.

You could do the globbing yourself which would keep the code clean.

```python
from glob import glob

Dataset.from_json(glob('folder/*.json'))
```

I think it should still be fine to log a warning message in case the folder contains different files? I also don't get why would this be breaking as in the end using `from_FILE_TYPE` should be able to read a specific file type only. Maybe some other use case I am not aware of but since globbing or this case not mentioned anywhere in the doc, I spent quite a bit of time trying to figure out where the issue was. Just making sure it's clear for users.
Issue: Allow image model (color conversion) to be specified as part of datasets Image() decode
State: closed
Author: rwightman

### Feature request

Typical torchvision / torch Datasets in image applications apply color conversion in the Dataset portion of the code as part of image decode, separately from the image transform stack. This is true for PIL.Image where convert is usually called in dataset, for native torchvision https://pytorch.org/vision/main/generated/torchvision.io.decode_jpeg.html, and similarly in tensorflow.data pipelines decode_jpeg or https://www.tensorflow.org/api_docs/python/tf/io/decode_and_crop_jpeg have a channels arg that allows controlling the image mode in the decode step.

datasets currently requires this pattern (from [examples](https://huggingface.co/docs/datasets/main/en/image_process)):
```
from torchvision.transforms import Compose, ColorJitter, ToTensor

jitter = Compose(
    [
         ColorJitter(brightness=0.25, contrast=0.25, saturation=0.25, hue=0.7),
         ToTensor(),
    ]
)

def transforms(examples):
    examples["pixel_values"] = [jitter(image.convert("RGB")) for image in examples["image"]]
    return examples
```




### Motivation

It would be nice to be able to handle `image.convert("RGB")` (or other modes) in the decode step, before applying torchvision transforms, this would reduce differences in code when handling pipelines that can handle torchvision, webdatset, or hf datasets with fewer code differences and without needing to handle image mode argument passing in two different stages of the pipelines...

### Your contribution

Can do a PR with guidance on how mode should be passed / set on the dataset.

Comments:
It would be a great addition indeed :)

This can be implemented the same way we have `sampling_rate` for Audio(): we just add a new parameter to the Image() type and take this parameter into account in `Image.decode_example`

EDIT: adding an example of how it can be used:

```python
ds = ds.cast_column("image", Image(mode=...))
```

Issue: IterableDataset `set_epoch` is ignored when DataLoader `persistent_workers=True`
State: closed
Author: rwightman

### Describe the bug

When persistent workers are enabled, the epoch that's set via the IterableDataset instance held by the training process is ignored by the workers as they are disconnected across processes.

PyTorch samplers for non-iterable datasets have a mechanism to sync this, datasets.IterableDataset does not.

In my own use of IterableDatasets I usually track the epoch count which crosses process boundaries in a multiprocessing.Value 

### Steps to reproduce the bug

Use a streaming dataset (Iterable) w/ the recommended pattern below and `persistent_workers=True` in the torch DataLoader. 

```
for epoch in range(epochs):
    shuffled_dataset.set_epoch(epoch)
    for example in shuffled_dataset:
        ...
```

### Expected behavior

When the canonical bit of code above is used with `num_workers > 0` and `persistent_workers=True`, the epoch set via `set_epoch()` is propagated to the IterableDataset instances in the worker processes


### Environment info
