Loading the model

You can load the model directly in Python:

python

from cheff.ldm.models.diffusion.ddpm_tab import EHRXDiff

model = EHRXDiff.from_pretrained("dek924/ehrxdiff_wnull")
model.eval()

Alternatively, you can download the weights via the Hugging Face Hub:

python

from huggingface_hub import hf_hub_download

wt_path = hf_hub_download("dek924/ehrxdiff_wnull", "pytorch_model.bin")

and then run the evaluation script included in our github repository (scripts/eval.py):

python scripts/eval.py \
    --sdm_path=${CHECKPOINT_PATH}/pytorch_model.bin \
    --save_dir=${CHECKPOINT_PATH}/images/seed${RAND_SEED} \
    --img_meta_dir=${IMG_META_DIR} \   # Directory containing metadata for MIMIC-CXR-JPG
    --img_root_dir=${IMG_ROOT_DIR} \   # Directory containing preprocessed images
    --tab_root_dir=${TAB_ROOT_DIR} \   # Directory containing tabular data
    --seed=${RAND_SEED} \
    --batch_size=${BATCHSIZE}
