# New Datasets Guide To add new datasets, check this [blog](https://huggingface.co/blog/YongchengYAO/medvision-dataset) for an introduction of MedVision dataset. # Requirement 📝 Note: `trust_remote_code` is no longer supported in datasets>=4.0.0, install `dataset` with `pip install datasets==3.6.0`
# Use ```python import os from datasets import load_dataset # Set data folder os.environ["MedVision_DATA_DIR"] = # Pick a dataset config name and split config = # e.g., "OAIZIB-CM_BoxSize_Task01_Axial_Test" split_name = "test" # use "test" for testing set config; use "train" for training set config # Get dataset ds = load_dataset( "YongchengYAO/MedVision", name=config, trust_remote_code=True, split=split_name, ) ``` 📝 List of config names [here](https://huggingface.co/datasets/YongchengYAO/MedVision/tree/main/info) (`./info`)
# Environment Variables ```bash # Set where data will be saved, requires ~1T for the complete dataset export MedVision_DATA_DIR= # Force download and process raw images, default to "False" export MedVision_FORCE_DOWNLOAD_DATA="False" # Force install dataset codebase, default to "False" export MedVision_FORCE_INSTALL_CODE="False" ```
# 📖 Essential Dataset Concept We cover some essential concepts that help we use the MedVision dataset with ease. ## Concepts: Dataset & Data Configuration - `MedVision`: the collection of public imaging data and our annotations - `dataset`: name of the public datasets, such `BraTS24`, `MSD`, `OAIZIB-CM` - `data-config`: name of predefined subsets - naming convention: `{dataset}_{annotation-type}_{task-ID}_{slice}_{split}` - `dataset`: [details](https://huggingface.co/datasets/YongchengYAO/MedVision#datasets) - `annotation-type`: - `BoxSize`: detection annotations (bounding box) - `TumorLesionSize`: tumor/lesion size annotations - `BiometricsFromLandmarks`: angle/distance annotations - `task-ID`: `Task[xx]` (Note, this is a local ID in the dataset, not a glocal ID in MedVision.) - For datasets with multiple image-mask pairs, we defined tasks in `medvision_ds/datasets/*/preprocess_*.py` - source: [medvision_ds](https://huggingface.co/datasets/YongchengYAO/MedVision/tree/main/src) - e.g., detection tasks for the `BraTS24` dataset is defined in the `benchmark_plan` in `medvision_ds/datasets/BraTS24/preprocess_detection.py` - `slice`: [`Sagittal`, `Coronal`, `Axial`] - `split`: [`Train`, `Test`] ## What's returned from MedVision Dataset? We only share the annotations (https://huggingface.co/datasets/YongchengYAO/MedVision/tree/main/Datasets). The data loading script [`MedVision.py`](https://huggingface.co/datasets/YongchengYAO/MedVision/blob/main/MedVision.py) will handle raw image downloading and processing. The returned fields in each sample is defined as followed. ⚠️ In `MedVision.py`, the class `MedVision(GeneratorBasedBuilder)` defines the feature dict and the method `_generate_examples()` builds the dataset.

## Dataset Building Workflow ### Workflow

MedVision Dataset Building Workflow (Black)

MedVision Dataset Building Workflow (White)

There are a few venues to control the dataset loading and building behavior: - **Rebuild Dataset (Arrow files)**: Use the `download_mode` argument in `load_dataset()` ([docs](https://huggingface.co/docs/datasets/v3.6.0/en/package_reference/builder_classes#datasets.DownloadMode)). - **[1]** Set `download_mode="force_redownload"` to ignore the cached Arrow files and trigger the data loading script `MedVision.py` to rebuild the dataset. - **Redownload Raw Data**: - **[2]** `MedVision_FORCE_DOWNLOAD_DATA`: Set this environment variable to `True` to force re-downloading raw images and annotations. - **[3]** `.downloaded_datasets.json`: This tracker file records downloaded status. Removing a dataset's entry here will trigger a re-download of the raw data for that dataset. > [!Note] ⚠️ > **How to properly update/redownload raw data?** > > If you need to update raw data (images, masks, landmarks) using [2] or [3], you **MUST ALSO** use [1] (`download_mode="force_redownload"`). > > Why? Because if Hugging Face finds a valid cached dataset (Arrow files), it will load it directly and **skip running the script entirely**. Without running the script, the environment variable [2] or tracker file [3] will never be checked. > > **Summary:** > - Update Arrow/Fields only: Use [1]. > - Update Raw Data: Use [1] **AND** ([2] or [3]). > > 🔥 We will maintain a [change log](https://huggingface.co/datasets/YongchengYAO/MedVision/blob/main/doc/changelog.md) for essential updates. ### Examples

Run this for the first time will download the raw data and build the dataset

```python import os from datasets import load_dataset # Set data folder wd = os.path.join(os.getcwd(), "Data-testing") os.makedirs(wd, exist_ok=True) os.environ["MedVision_DATA_DIR"] = wd # Pick a dataset config name and split config = "OAIZIB-CM_BoxSize_Task01_Axial_Test" split_name = "test" # use "test" for testing set config; use "train" for training set config # Get dataset ds = load_dataset( "YongchengYAO/MedVision", name=config, trust_remote_code=True, split=split_name, ) ```

Run the same script again will use the cached dataset

Adding `download_mode="force_redownload"` will skip raw data downloading and rebuild the dataset

Adding `download_mode="force_redownload"` and `os.environ["MedVision_FORCE_DOWNLOAD_DATA"] = "True"` will redownload raw data and rebuild the dataset

```python import os from datasets import load_dataset # Set data folder wd = os.path.join(os.getcwd(), "Data-testing") os.makedirs(wd, exist_ok=True) os.environ["MedVision_DATA_DIR"] = wd # Pick a dataset config name and split config = "OAIZIB-CM_BoxSize_Task01_Axial_Test" split_name = "test" # use "test" for testing set config; use "train" for training set config # Force redownload os.environ["MedVision_FORCE_DOWNLOAD_DATA"] = "True" # Get dataset ds = load_dataset( "YongchengYAO/MedVision", name=config, trust_remote_code=True, split=split_name, download_mode="force_redownload", ) ```

### Download Mode in MedVision Dataset

(Advanced) Understand how the customized dataset loading script `MedVision.py` changes the behavior of `download_mode` in `load_dataset()`

# Advanced Usage The dataset codebase `medvision_ds` can be used to scale the dataset, including adding new annotation types and datasets. ## 🛠️ **Install** ```bash pip install "git+https://huggingface.co/datasets/YongchengYAO/MedVision.git#subdirectory=src" pip show medvision_ds ``` or ```bash # First, install the benchmark codebase: medvision_bm pip install "git+https://github.com/YongchengYAO/MedVision.git" # Install the dataset codebase: medvision_ds python -m medvision_bm.benchmark.install_medvision_ds --data_dir ``` ## 🧑🏻‍💻 Use [utility functions](https://huggingface.co/datasets/YongchengYAO/MedVision/tree/main/src/medvision_ds/utils) for image processing ```python from medvision_ds.utils.data_conversion import ( convert_nrrd_to_nifti, convert_mha_to_nifti, convert_nii_to_niigz, convert_bmp_to_niigz, copy_img_header_to_mask, reorient_niigz_RASplus_batch_inplace, ) from medvision_ds.utils.preprocess_utils import ( split_4d_nifti, ) ``` ## 👩🏼‍💻Examples of dataset scaling: - Setup automatic data processing pipeline - Download preprocessed data from HF: [medvision_ds/datasets/OAIZIB_CM/download.py](https://huggingface.co/datasets/YongchengYAO/MedVision/blob/main/src/medvision_ds/datasets/OAIZIB_CM/download.py) - Download and processed data from source: [medvision_ds/datasets/BraTS24/download_raw.py](https://huggingface.co/datasets/YongchengYAO/MedVision/blob/main/src/medvision_ds/datasets/BraTS24/download_raw.py) - Prepare annotations - Generate b-box annotations from segmentation masks: - [medvision_ds/datasets/BraTS24/preprocess_detection.py](https://huggingface.co/datasets/YongchengYAO/MedVision/blob/main/src/medvision_ds/datasets/BraTS24/preprocess_detection.py) - Generate tumor/lesion size (TL) annotations from segmentation masks: - [medvision_ds/datasets/BraTS24/preprocess_biometry.py](https://huggingface.co/datasets/YongchengYAO/MedVision/blob/main/src/medvision_ds/datasets/BraTS24/preprocess_biometry.py) - Generate angle/distance (AD) annotations from landmarks: - [medvision_ds/datasets/Ceph_Biometrics_400/preprocess_biometry.py](https://huggingface.co/datasets/YongchengYAO/MedVision/blob/main/src/medvision_ds/datasets/Ceph_Biometrics_400/preprocess_biometry.py) - [medvision_ds/datasets/FeTA24/preprocess_biometry.py](https://huggingface.co/datasets/YongchengYAO/MedVision/blob/main/src/medvision_ds/datasets/FeTA24/preprocess_biometry.py)
