-A toolkit to download, augment, and benchmark Open-PMC; a large dataset of image-text pairs extracted from open-access scientific articles on PubMedCentral.
+Open-PMC is a toolkit for **training and evaluating** CLIP-style medical visionβlanguage models on
+large-scale imageβtext pairs mined from open-access PubMed Central articles. It spans the full
+pipeline: downloading and parsing figureβcaption pairs, contrastive pretraining with
+[`mmlearn`](https://github.com/VectorInstitute/mmlearn), and a **zero-shot evaluation** suite.
+
+**Evaluation** measures how well the learned image and text embeddings align, with no task-specific
+fine-tuning:

## Installing dependencies
-We use
-[poetry](https://python-poetry.org/docs/#installation)
-for dependency management. Please make sure it is installed.
-Then, follow below instructions to set up your virtual environment.
+We use [poetry](https://python-poetry.org/docs/#installation) for dependency management.
-1. Create a venv with python3.10 and activate it.
```bash
-python --version # must print 3.10
-python -m venv
-source /bin/activate
-```
-
-2. Navigate to the root directory of pmc-data-extraction repository and install dependencies.
-Two of the required dependencies are [mmlearn](https://github.com/VectorInstitute/mmlearn) and [open_clip](https://github.com/mlfoundations/open_clip).
-You have the option to either install them with `pip` or from source.
+# 1. Create and activate a Python 3.10 environment
+python -m venv .venv && source .venv/bin/activate
-To install `mmlearn` and `open_clip` with `pip`, run
-```bash
+# 2. Install the package with mmlearn + open_clip (from pip)
cd path/to/pmc-data-extraction
pip install --upgrade pip
poetry install --no-root --with test,open_clip,mmlearn --all-extras
```
-then skip to step 6: Check Installations.
-To install `mmlearn` and `open_clip` from source, run
-```bash
-cd path/to/pmc-data-extraction
-pip install --upgrade pip
-poetry install --no-root --with test --all-extras
-```
-The above command assumes that you would install `mmlearn` or `open_clip` packages from source using the submodules found in `pmc-data-extraction/openpmcvl/`experiment.
+Prefer building [`mmlearn`](https://github.com/VectorInstitute/mmlearn) and
+[`open_clip`](https://github.com/mlfoundations/open_clip) from source? Install without them
+(`poetry install --no-root --with test --all-extras`), then pull the submodules and install them:
-3. Clone `mmlearn` and `open_clip` submodules.
```bash
-git submodule init
-git submodule update
+git submodule update --init
+pip install -e openpmcvl/experiment/mmlearn
+cd openpmcvl/experiment/open_clip && make install && make install-training
```
-You should see the source files inside `pmc-data-extraction/openpmcvl/experiment/open_clip` and `pmc-data-extraction/openpmcvl/experiment/mmlearn`.
-4. Install `mmlearn` from source.
-```bash
-cd openpmcvl/experiment/mmlearn
-python3 -m pip install -e .
-```
+Verify with `python -c "import mmlearn, open_clip; print(mmlearn.__file__, open_clip.__file__)"`.
-5. Install `open_clip` from source.
-```bash
-cd ../open_clip
-make install
-make install-training
-```
-
-6. Check installations.
-```bash
-pip freeze | grep mmlearn
-pip freeze | grep open_clip
-python
-> import mmlearn
-> import open_clip
-> mmlearn.__file__
-> open_clip.__file__
-```
+## Benchmarking
-**Note:** Since these submodules (`mmlearn` and `open_clip`) are only part of the main branch in a single repository, if you change your branch to a branch where these submodules don't exist, your python interpretor won't be able to find these packages and you will face errors.
+We use [`mmlearn`](https://github.com/VectorInstitute/mmlearn) to run training and evaluation.
+A minimal training run:
-
-## Download and parse image-caption pairs from Pubmed Articles
-The codebase used to download Pubmed articles and parse image-text pairs from them is stored in `openpmcvl/foundation`.
-This codebase heavily relies on [Build PMC-OA](https://github.com/WeixiongLin/Build-PMC-OA) codebase[[1]](#1).
-To download and parse articles with licenses that allow commercial use, run
-```bash
-# activate virtual environment
-source /path/to/your/venv/bin/activate
-# navigate to root directory of the package
-cd openpmcvl/foundation
-# download all 11 volumes with commercailly usable license
-python -u src/fetch_oa.py --num-retries 5 --extraction-dir path/to/download/directory/commercial --license-type comm --volumes 0 1 2 3 4 5 6 7 8 9 10 11
-```
-To download and parse open-access articles which are not allowed commercial use, run
```bash
-python -u src/fetch_oa.py --num-retries 5 --extraction-dir path/to/download/directory/noncommercial --license-type noncomm --volumes 1 2 3 4 5 6 7 8 9 10 11
-```
-To download and parse open-access articles which other licenses than what is mentioned above, run
-```bash
-python -u src/fetch_oa.py --num-retries 5 --extraction-dir path/to/download/directory/other --license-type other --volumes 0 1 2 3 4 5 6 7 8 9 10 11
-```
-
-
-## Run Benchmarking Experiments
-We use `mmlearn` to run benchmarking experiments.
-Many experiments can be run with our dataset and `mmlearn`.
-A simple example of training with our dataset is given below:
-```bash

-# set pythonpath
export PYTHONPATH="./"

+Zero-shot evaluation of an open_clip-format checkpoint with the BiomedCLIP architecture
+(ViT-B/16 image encoder + PubMedBERT text encoder), such as the **Open-PMC-18M** model:

+
+Every script loads the checkpoint through the encoders' `checkpoint_path` argument (an
+open_clip-native `state_dict` with `visual.*` / `text.*` keys) β no Lightning
+`resume_from_checkpoint` conversion needed. Retrieval uses the `biomedclip_localckpt_retrieval`
+config; classification uses `biomedclip_localckpt_ZSC`.
+
+## 1. Setup
+
+Install the repo (see the [top-level README](../README.md)). **No checkpoint setup is needed** β
+by default the scripts evaluate the released **Open-PMC-18M** checkpoint
+([vector-institute/open-pmc-18m-clip](https://huggingface.co/vector-institute/open-pmc-18m-clip)),
+which is downloaded automatically from the Hugging Face Hub on first run.
+
+To evaluate a **different** checkpoint instead, set `CKPT` to a local open_clip `.pt`/`.bin` file
+(or another `hf-hub:/` reference).
+
+## 2. Run
+
+**Every dataset reads its location from a `*_ROOT_DIR` environment variable** (see
+[Data setup](#3-data-setup) below). If a `*_ROOT_DIR` is not set, the run fails with a Hydra
+*"missing mandatory value"* error for `root_dir`.
+
+```bash
+# retrieval β evaluates the released Open-PMC-18M checkpoint by default
+QUILT_ROOT_DIR=/data/quilt bash evaluation/zero_shot_retrieval/quilt.sh
+
+# classification
+PCAM_ROOT_DIR=/data/pcam bash evaluation/zero_shot_classification/pcam.sh
+NAME=pathmnist MEDMNISTPLUS_ROOT_DIR=/data/medmnist bash evaluation/zero_shot_classification/medmnist.sh
+
+# to evaluate your own checkpoint instead, set CKPT to a local file
+CKPT=/path/to/checkpoint.pt QUILT_ROOT_DIR=/data/quilt bash evaluation/zero_shot_retrieval/quilt.sh
+```
+
+Retrieval reports Recall@{10, 50, 200} in both directions; classification reports top-1 accuracy.
+
+## 3. Data setup
+
+Set the listed `*_ROOT_DIR` before running. Datasets marked **auto** download themselves from the
+Hugging Face Hub into that directory (make it writable); datasets marked **manual** must be
+downloaded from the source first and arranged as shown.

+
+**MedMNIST+** β `$MEDMNISTPLUS_ROOT_DIR/` with the 224px npz files, e.g. `pathmnist_224.npz`,
+`dermamnist_224.npz`, `bloodmnist_224.npz`, `organamnist_224.npz`, β¦ Select one with `NAME=`.
+
+**Auto datasets** (PCam, BACH, NCT-CRC-HE) need only a writable `*_ROOT_DIR`; on first run they
+download into `/scratch/` and cache into `/cache/`.
+
+## Notes
+
+- **Different checkpoint / dataset.** Point `CKPT` at any open_clip-format checkpoint with the
+ BiomedCLIP architecture. To evaluate another retrieval dataset, copy a script and swap the
+ dataset name (e.g. `+datasets@datasets.test.=`).
+- **SLURM.** The scripts run a single process on the local GPU. To submit to a cluster, wrap the
+ `mmlearn_run` call with `--multirun` and the hydra submitit launcher, or call the script from
+ your `sbatch` wrapper.
