SPPLDistribution

✓ from sppl.distributions import SPPLDistribution

✗ from sppl import SPPLDistribution

SPPLDistribution is in the distributions submodule.

Model

✓ from sppl import Model

Direct import from the top-level package.

Variable

✓ from sppl import Variable

Direct import from the top-level package.

Creates a simple probabilistic model with a Bernoulli variable.

from sppl import Model, Variable from sppl.distributions import SPPLDistribution import os # Define a simple model: flip a fair coin model = Model() with model: x = Variable('x', SPPLDistribution.bernoulli(0.5)) # Check the model structure print(model)

Known issues

breakingIn version 2.0.0, the package structure changed: distributions are now in 'sppl.distributions' submodule, not directly under 'sppl'.

fix

Update imports: use 'from sppl.distributions import SPPLDistribution' instead of 'from sppl import SPPLDistribution'.

affects: <2.0.0

deprecatedThe function 'sppl.distributions.Distribution' is deprecated in favor of 'SPPLDistribution'.

fix

Replace 'Distribution' with 'SPPLDistribution' in your code.

affects: >=2.0.0

gotchaModel variables must be defined inside a 'with model:' block, otherwise they are not added to the model.

fix

Always use 'with model:' context manager when defining variables.

affects: all
