embpred-deploy 0.1.1

Emb Deployment Package for Image Inference using Faster-RCNN and custom classification networks

embpred_deploy Documentation

Overview

embpred_deploy is a deployment package for running inference using Faster-RCNN and custom classification networks. It supports various input modes, including timelapse inference, single-image inference, and multi-focal depth inference.

Installation

1. Create and activate a Conda environment with Python 3.12

To ensure compatibility, create a new Conda environment:

conda create -n embd python=3.12
conda activate embd

2. Install embpred_deploy via pip

Once the environment is set up, install the package:

pip install embpred_deploy

Important: The PyPI package does not include model weights due to size limitations. You must download the model weights separately (see Model Weights Installation below).

3. Install embpred_deploy via Git

Alternatively, if you prefer to pull the latest code directly from GitHub, run:

git clone https://github.com/berkyalcinkaya/embpred_deploy.git
cd embpred_deploy
pip install -e .

Model Weights Installation

⚠️ REQUIRED: Pretrained model weights are NOT included in the PyPI package due to size limitations. You must download them separately to use the package.

Model weights are stored on Google Drive. To use the latest trained models, download the weight files from:

Google Drive Weights

Install Weights

After downloading the zip file, run the installation script to extract and move the weight files into the appropriate models folder:

python -m embpred_deploy.install_weights /path/to/your/downloaded_weights.zip

This script:

• Unzips the archive
• Moves any .pth or .pt files to the embpred_deploy/models directory

Note: The embpred_deploy/models directory will be created automatically if it doesn't exist.

Usage Instructions

The inference script supports three modes:

1. Timelapse Inference

Use the --timelapse-dir argument to process a sequence of images. This mode supports two directory structures:

• Single-image per timepoint

  • All images are stored in one directory.
  • Each image is loaded in grayscale and converted to RGB (duplicated channels).

• Multiple focal depths per timepoint

  • The images must be organized into three subdirectories, each representing a different focal depth.
  • The script aligns images based on sorted filenames across subdirectories.

Example Command:

embpred_deploy --timelapse-dir /path/to/your/timelapse_data --model-name YOUR_MODEL_NAME

Output:

• Raw outputs: raw_timelapse_outputs.npy
• If --postprocess is enabled:
  • max_prob_classes.csv
  • max_prob_classes.png

2. Single Image Inference

Use the --single-image argument to run inference on a single image. The image is processed by duplicating its grayscale channel into RGB.

Example Command:

embpred_deploy --single-image /path/to/your/image.jpg --model-name YOUR_MODEL_NAME

3. Three-Focal Depth Inference

Provide three separate focal depth images using the --F_neg15, --F0, and --F15 arguments.

Example Command:

embpred_deploy --F_neg15 /path/to/F_neg15.jpg --F0 /path/to/F0.jpg --F15 /path/to/F15.jpg --model-name YOUR_MODEL_NAME

Assumptions & Notes

Input Image Format

• Single image inference:
  • Image is loaded in grayscale and converted to 3-channel RGB.
• Timelapse mode:
  • Image filenames must be sorted to ensure correct timepoint alignment.

Model Output

• Regular inference:
  • The script maps raw model output to class labels.
• Timelapse inference:
  • Raw probability vectors are returned unless --postprocess is enabled.

Dependencies

The package requires the following libraries (installed via pip or Conda):

• pytorch
• torchvision
• opencv-python
• numpy
• matplotlib
• tqdm

Ensure these dependencies are installed in your environment before running inference.

Development and Deployment

Setting up for Development

To set up the development environment:

# Clone the repository
git clone https://github.com/berkyalcinkaya/embpred_deploy.git
cd embpred_deploy

# Install development dependencies
pip install -r requirements-dev.txt

# Install the package in editable mode
pip install -e .

Deploying to PyPI

To deploy the package to PyPI:

1. Install deployment tools:

   pip install -r requirements-dev.txt
   

2. Run the deployment script:

   python build_and_deploy.py
   

3. Or manually build and deploy:

   # Clean previous builds
   rm -rf build/ dist/ *.egg-info/
   
   # Build the package
   python -m build
   
   # Check the package
   python -m twine check dist/*
   
   # Upload to TestPyPI (recommended first)
   python -m twine upload --repository testpypi dist/*
   
   # Upload to PyPI (production)
   python -m twine upload dist/*
   

PyPI Credentials

You'll need to set up your PyPI credentials. Create a ~/.pypirc file:

[distutils]
index-servers =
    pypi
    testpypi

[pypi]
repository = https://upload.pypi.org/legacy/
username = your_username
password = your_password

[testpypi]
repository = https://test.pypi.org/legacy/
username = your_username
password = your_password
