PyTorch dependencies. + +## Architecture Overview + +We use a multi-stage container architecture that supports both ML frameworks: + +1. **Base ML Image**: `vm/tf-pytorch/Dockerfile` - Contains both TensorFlow and PyTorch with CUDA support +2. **Application Image**: `Dockerfile` - Builds on the ML base and adds the mouse-tracking application +3. **Singularity Definition**: `vm/singularity.def` - Creates Singularity containers from the Docker images + +## Docker Support + +### Base ML Image (`vm/tf-pytorch/Dockerfile`) + +The base image provides: +- **Python 3.10** runtime environment +- **PyTorch 2.5.1** with CUDA 12.4 support (`cu124`) +- **TensorFlow 2.19.0** with CUDA support +- Essential system dependencies (ffmpeg, libjpeg8-dev, etc.) + +Key features: +- Uses PyTorch's official CUDA index for GPU acceleration +- TensorFlow includes bundled CUDA runtime via `tensorflow[and-cuda]` +- Both frameworks can coexist and utilize GPU resources +- Pinned versions prevent dependency conflicts + +### Application Image (`Dockerfile`) + +The main application container: +- Extends from `aberger4/mouse-tracking-base:python3.10-slim` (published ML base) +- Uses `uv` for fast Python package management +- Installs only runtime dependencies (excludes dev/test/lint groups) +- Provides `mouse-tracking-runtime` CLI as the main entrypoint + +## Singularity Support + +### Definition File (`vm/singularity.def`) + +The Singularity container: +- Bootstraps from the Docker image `aberger4/mouse-tracking:python3.10-slim` +- Inherits all TensorFlow/PyTorch capabilities from the Docker base +- Copies model files into `/workspace/models/` during build +- Provides HPC-compatible runtime environment + +### Building Singularity Images + +```bash +singularity build mouse-tracking-runtime.sif vm/singularity.def +``` + +## Framework Compatibility + +Both frameworks are configured to work together: + +### GPU Access +- **Docker**: Uses NVIDIA runtime with `NVIDIA_VISIBLE_DEVICES=all` +- **Singularity**: Inherits GPU access from host system +- **CUDA**: Both frameworks use compatible CUDA versions (12.4/12.x) + +### Model Runtimes +- **PyTorch**: Used for HRNet-based pose estimation models +- **TensorFlow**: Handles arena corners, segmentation, and identity tracking + +## Usage Examples + +### Docker +```bash +# Build and run the application container +docker build -t mouse-tracking-runtime . +docker run --gpus all mouse-tracking-runtime mouse-tracking-runtime --help +``` + +### Singularity +```bash +# Build and run the Singularity container +singularity build mouse-tracking-runtime.sif vm/singularity.def +singularity run --nv mouse-tracking-runtime.sif mouse-tracking-runtime --help +``` + +The `--nv` flag enables NVIDIA GPU support in Singularity environments. \ No newline at end of file diff --git a/vm/deployment-runtime-RHEL9.def b/vm/deployment-runtime-RHEL9.def deleted file mode 100644 index 950c97a..0000000 ---
