• flwr = { version = "1.0.0a0", allow-prereleases = true, extras = ["simulation"] } (with extras)

Install flwr from a local copy of the Flower source code via pyproject.toml:

• flwr = { path = "../../", develop = true } (without extras)

• flwr = { path = "../../", develop = true, extras = ["simulation"] } (with extras)

Install flwr from a local wheel file via pyproject.toml:

• flwr = { path = "../../dist/flwr-1.8.0-py3-none-any.whl" } (without extras)

• flwr = { path = "../../dist/flwr-1.8.0-py3-none-any.whl", extras = ["simulation"] } (with extras)
