StringBasedFunction(fn, function_purpose)

Autograd function for string-based functions.

class textgrad.autograd.string_based_ops.StringBasedFunction(fn, function_purpose)

Bases: Function

Autograd function for string-based functions.

Parameters:

• fn (Callable) – The function to execute for the forward pass.

• function_purpose (str) – The description of the purpose of the function. Analogous to role description for variables.

backward(response, function_purpose, inputs, backward_engine)

Parameters:

• response (Variable)

• function_purpose (str)

• inputs (Dict[str, Variable])

• backward_engine (EngineLM)

forward(inputs, response_role_description=None)

The forward mode for string-based functions

Parameters:

• inputs (Dict[str, Variable]) – The arguments that will be passed to the string based function. The keys are the names of the arguments.

• response_role_description (str) – The role description of the output variable.

Return type:

Variable
