"Hi, I've investigated this issue and can confirm the bug. Here are my findings:\n\n**1. Reproduction:**\nI was able to reproduce the issue on the latest `main` branch. Using the provided code snippet, `snapshot_download` correctly populates the custom `cache_dir`, but `load_dataset` with the same `cache_dir` triggers a full re-download and re-processing of the dataset, ignoring the existing cache.\n\n**2. Investigation:**\nI traced the `cache_dir` parameter from `load_dataset` down to the `DatasetBuilder` class in `src/datasets/builder.py`. The root cause seems to be a mismatch between the cache path structure created by `snapshot_download` and the path structure expected by the `DatasetBuilder`.\n\nSpecifically, the `_relative_data_dir` method in `DatasetBuilder` constructs a path using `namespace___dataset_name` (with three underscores), while the cache from `snapshot_download` appears to use a `repo_id` based format like `datasets--namespace--dataset_name` (with double hyphens).\n\n**3. Attempted Fix & Result:**\nI attempted a fix by modifying the `_relative_data_dir` method to replace the path separator \"/\" in `self.repo_id` with \"--\", to align it with the `snapshot_download` structure.\n\nThis partially worked: `load_dataset` no longer re-downloads the files. However, it still re-processes them every time (triggering \"Generating train split...\", etc.) instead of loading the already processed Arrow files from the cache.\n\nThis suggests the issue is deeper than just the directory name and might be related to how the builder verifies the integrity or presence of the processed cache files.\n\nI hope these findings are helpful for whoever picks up this issue."

"Hi ! it would be cool to convert this dataset to Parquet. This will make it work for `datasets>=4.0`, enable the Dataset Viewer and make it more reliable to load/stream (currently it uses a loading script in python and those are known for having issues sometimes)\n\nusing `datasets==3.6.0`, here is the command to convert it and open a Pull Request:\n\n```\ndatasets-cli convert_to_parquet espnet/yodas2 --trust_remote_code\n```\n\nThough it's likely that the `UnicodeDecodeError` comes from the loading script. If the script has a bug, it must be fixed to be able to convert the dataset without errors"

"> If we have already loaded the dataset, why doing to_iterable_dataset?

How to make it comparable to to_iterable_dataset without loading the whole dataset into RAM?\n\nYou can aim for saturating your bandwidth using a DataLoader with num_workers and prefetch_factor. The maximum speed will be your internet bandwidth (unless your CPU is a bottlenbeck for CPU operations like image decoding).",
"> > If we have already loaded the dataset, why doing to_iterable_dataset? Does it go through the dataset faster than map-style dataset?\n> \n> yes, it makes a faster DataLoader for example (otherwise DataLoader uses `__getitem__` which is slower than iterating)\n\nOkay, but `__getitem__` seems suitable for distributed settings. A distributed sampler would dispatch distinct indexes to each rank (rank0 got 0,1,2,3, rank1 got 4,5,6,7), however, if we make it `to_iterable_dataset`, then each rank needs to iterate all the samples, making it slower (i,e, rank1 got 0,1,2,3, rank2 got 0,1,2,3,(4,5,6,7))\n\nWhat's your opinion here?",
"> however, if we make it to_iterable_dataset, then each rank needs to iterate all the samples, making it slower (i,e, rank1 got 0,1,2,3, rank2 got 0,1,2,3,(4,5,6,7))\n\nActually if you specify `to_iterable_dataset(num_shards=world_size)` (or a factor of world_size) and use a `torch.utils.data.DataLoader` then each rank will get a subset of the data thanks to the sharding. E.g. rank0 gets 0,1,2,3 and rank1 gets 4,5,6,7.\n\nThis is because `datasets.IterableDataset` subclasses `torch.utils.data.IterableDataset` and is aware of the current rank.",
"Got it, very nice features `num_shards` 👍🏻 \n\nI would benchmark `to_iterable_dataset(num_shards=world_size)` against traditional map-style one in distributed settings in the near future.",

"Hey @xiagod \n\nThe easiest way to add your custom data to Hugging Face Datasets is to use the built-in load_dataset function with your local files. Some examples include:\n\nCSV files:\nfrom datasets import load_dataset\ndataset = load_dataset(\"csv\", data_files=\"my_file.csv\")\n\nJSON or JSONL files:\nfrom datasets import load_dataset\ndataset = load_dataset(\"json\", data_files=\"my_file.json\")\n\n\nImages stored in folders (e.g. data/train/cat/, data/train/dog/):\nfrom datasets import load_dataset\ndataset = load_dataset(\"imagefolder\", data_dir=\"/path/to/pokemon\")\n\n\nThese methods let you quickly create a custom dataset without needing to write a full script.\n\nMore information can be found in Hugging Face's tutorial \"Create a dataset\" or \"Load\" documentation here: \n\nhttps://huggingface.co/docs/datasets/create_dataset \n\nhttps://huggingface.co/docs/datasets/loading#local-and-remote-files\n\n\n\nIf you want to submit your dataset to the Hugging Face Datasets GitHub repo so others can load it follow this guide: \n\nhttps://huggingface.co/docs/datasets/upload_dataset \n\n\n"

"Hey @zdzichukowalski, I was not able to reproduce this on python 3.11.9 and datasets 3.6.0. The contents of \"body\" are correctly parsed as a string and no other fields like timestamps are created. Could you try reproducing this in a fresh environment, or posting the complete code where you encountered that stacktrace? (I noticed in the stacktrace you had a bigger program, perhaps there are some side effects)",
"Hi @zdzichukowalski, thanks for reporting this!\n\nTo help investigate this further, could you please share the following:\n\nExact contents of the data.jsonl file you're using — especially the first few lines that trigger the error.\n\nThe full code snippet you used to run load_dataset(), along with any environment setup (if not already shared).\n\nCan you confirm whether the issue persists when running in a clean virtual environment (e.g., with only datasets, pyarrow, and their dependencies)?\n\nIf possible, could you try running the same with an explicit features schema, like:\n\n```\nfrom datasets import load_dataset, Features, Value\nfeatures = Features({\"body\": Value(\"string\")})\nds = load_dataset(\"json\", data_files=\"data.jsonl\", split=\"train\", features=features)\n```\nAlso, just to clarify — does the \"body\" field contain plain string content, or is it sometimes being parsed from multi-line or structured inputs (like embedded JSON or CSV-like text)?\n\nOnce we have this info, we can check whether this is a schema inference issue, a PyArrow type coercion bug, or something else.",
"Ok I can confirm that I also cannot reproduce the error in a clean environment with the minimized version of the dataset that I provided. Same story for the old environment. Nonetheless the bug still happens in the new environment with the full version of the dataset, which I am providing now. Please let me know if now you can reproduce the problem.\n\nAdditionally I'm attaching result of the `pip freeze` command.\n\n[datasets-issues.jsonl.zip](https://github.com/user-attachments/files/21081755/datasets-issues.jsonl.zip)\n[requirements.txt](https://github.com/user-attachments/files/21081776/requirements.txt)\n\n@ArjunJagdale running with explicit script gives the following stack:\n[stack_features_version.txt](https://github.com/user-attachments/files/21082056/stack_features_version.txt)\n\nThe problematic `body` field seems to be e.g. content of [this comment](https://github.com/huggingface/datasets/issues/5596#issue-1604919993) from Github in which someone provided a stack trace containing json structure ;) I would say that it is intended to be a plain string. \n\nTo find a part that triggers an error, simply search for the \"timestamp[s]\" in the dataset. There are few such entries.\n\nI think I provided all the information you asked. \n\nOh, and workaround I suggested, that is convert `.jsonl` to `.json` worked for me.\n\nP.S\n1. @itsmejul the stack trace I provided is coming from running the two-liner script that I attached. There is no bigger program, although there were some jupiter files alongside the script, which were run in the same env. I am not sure what part of the stack trace suggests that there is something more ;) \n\n2. Is it possible that on some layer in the python/env/jupiter there is some caching mechanism for files that would give false results for my minimized version of the dataset file? There is of course possibility that I made a mistake and run the script with the wrong file, but I double and triple checked things before creating an issue. Earlier I wrote that \"(...) changing the file extension to `.json` or `.txt` avoids the problem\". But with the full version this is not true(when I change to `txt`), and minimized version always works. So it looks like that when I changed the extension to e.g. `txt` then a minimized file loaded from the disk and it was parsed correctly, but every time when I changed back to `jsonl` my script must have used an original content of the file - the one before I made a minimization. But this is still all strange because I even removed the fields before and after the body from my minimized `jsonl` and there were some different errors(I mention it in my original post), so I do not get why today I cannot reproduce it in the original env... \n\n",
"Hi @zdzichukowalski, thanks again for the detailed info and files!\n\nI’ve reviewed the `datasets-issues.jsonl` you shared, and I can now confirm the issue with full clarity:\n\nSome entries in the `\"body\"` field contain string content that resembles schema definitions — for example:\n\n```\nstruct<type: string, action: string, datetime: timestamp[s], ...>\n```\n\nThese strings appear to be copied from GitHub comments or stack traces (e.g., from #5596)\n\nWhen using the `.jsonl` format, `load_dataset()` relies on row-wise schema inference via PyArrow. If some rows contain real structured fields like `pull_request.merged_at` (a valid timestamp), and others contain schema-like text inside string fields, PyArrow can get confused while unifying the schema — leading to cast errors.\n\nThat’s why:\n\n* Using a reduced schema like `features={\"body\": Value(\"string\")}` fails — because the full table has many more fields.\n* Converting the file to `.json` (a list of objects) works — because global schema inference kicks in.\n* Filtering the dataset to only the `body` field avoids the issue entirely.\n\n### Suggested Workarounds\n\n* Convert the `.jsonl` file to `.json` to enable global schema inference.\n* Or, preprocess the `.jsonl` file to extract only the `\"body\"` field if that’s all you need.",
"So in summary should we treat it as a low severity bug in `PyArrow`, in `Datasets` library, or as a proper behavior and do nothing with it?",
"You are right actually! I’d also categorize this as a low-severity schema inference edge case, mainly stemming from PyArrow, but exposed by how datasets handles .jsonl inputs.\n\nIt's not a bug in datasets per se, but confusing when string fields (like body) contain text that resembles schema — e.g., \"timestamp[s]\".\n\nMaybe @lhoestq — could this be considered as a small feature/improvement?"

"> I need this feature right now. It would be great if it could automatically fill in None for non-existent keys instead of reporting an error.\r\n\r\nHi @aihao2000, Just to confirm — I have done the changes you asked for!\r\nIf you pass columns=[\"key1\", \"key2\", \"optional_key\"] to load_dataset(..., columns=...), and any of those keys are missing from the input JSON objects, the loader will automatically fill those columns with None values, instead of raising an error.",

"I believe there are other occurences of cases like this, like select_columns, select, filter, shard and flatten, could you also fix the docstring for them as well before we merge ?",
"Done! @lhoestq! I've updated the docstring examples for the following methods to clarify that they return new datasets instead of modifying in-place:\r\n\r\n- `select_columns`\r\n- `select`\r\n- `filter`\r\n- `shard`\r\n- `flatten`\r\n",
