More script examples on github

from daphne.context.daphne_context import DaphneContext
import numpy as np

dc = DaphneContext()

# Create data in numpy.
a = np.arange(8.0).reshape((2, 4))

# Transfer data to DaphneLib (lazily evaluated).
X = dc.from_numpy(a)

print("How DAPHNE sees the data from numpy:")
X.print().compute()

# Add 100 to each value in X.
X = X + 100.0

# Compute in DAPHNE, transfer result back to Python.
print("\nResult of adding 100 to each value, back in Python:")
print(X.compute())

Build

Build Python wheel package:

pip install build
./clean.sh && python3 -m build --wheel

Dev Setup

With editable install

python3 -m venv .venv
source .venv/bin/activate
pip install -e .

Publish

Use twine for publishing to PyPI. Install via pip install twine.

1. Set version in pyproject.toml
2. Build according to Build section
3. twine check dist/daphne-<version>-py3-none-any.whl
   • checks the wheel file
4. twine upload -u __token__ dist/daphne-<version>-py3-none-any.whl
   • to publish to PyPI
   • twine prompts for your token
