torch.tx.createLazyExpression

function createLazyExpression(pattern: string): LazyExpression

Create a lazy expression from a pattern string.

The expression is parsed but not evaluated until .execute() is called. This enables deferred computation with variable substitution.

Parameters

patternstring: The expression pattern to compile

Returns

LazyExpression– A LazyExpression that can be bound and executed later

Examples

// Create a lazy expression
const linear = $.lazy('x @ w + b');

// Bind variables incrementally
const withParams = linear.with({ w: weights, b: bias });

// Execute with different inputs
for (const batch of data) {
  const output = withParams.execute({ x: batch });
  // Process output...
}

// Or provide all at once
const result = linear.execute({ x: input, w: weights, b: bias });
