deepspatial 1.0.0

DeepSpatial is a package for true 3D reconstruction of spatial omics tissues from serial 2D slices, built with PyTorch and designed to work smoothly with AnnData/Scanpy workflows.

3D spatial omics reconstruction

DeepSpatial provides an end-to-end framework for learning continuous 3D tissue representations:

• Reconstructs missing biological structure between adjacent sections.
• Jointly models spatial coordinates, gene expression, and cell identities.
• Supports large-scale training and sampling with GPU acceleration.
• Produces outputs that can be directly used in downstream single-cell/spatial analysis.

The package exposes a high-level API (DeepSpatial) for data setup, model training, and 3D reconstruction with minimal boilerplate.

Installation

Recommended (PyPI):

pip install deepspatial

From source (development):

git clone https://github.com/yyh030806/DeepSpatial.git
cd DeepSpatial
pip install -e .

If you use GPU, install a PyTorch build matching your CUDA version.

Quick start

1. Download an example dataset first: Google Drive dataset folder

   Then place files under data/merfish_mouse_hypothalamus/.

2. Run DeepSpatial:

import glob
import scanpy as sc
import deepspatial as ds

adatas = [
    sc.read_h5ad(p)
    for p in sorted(glob.glob("data/merfish_mouse_hypothalamus/merfish_*.h5ad"))
]

model = ds.DeepSpatial()
model.setup_data(adatas)
model.build_model()
model.fit(max_epochs=100)

adata_3d = model.reconstruct_full_volume(adatas, thickness=10.0)
