[Bug] Manual tool calling not working #8933
Description
What happened?
The manual tool calling provided in the documentation is itself not working giving the error provided in the description.
Steps to reproduce
import dspy
class ToolSignature(dspy.Signature):
"""Signature for manual tool handling."""
question: str = dspy.InputField()
tools: list[dspy.Tool] = dspy.InputField()
outputs: dspy.ToolCalls = dspy.OutputField()
def weather(city: str) -> str:
"""Get weather information for a city."""
return f"The weather in {city} is sunny"
def calculator(expression: str) -> str:
"""Evaluate a mathematical expression."""
try:
result = eval(expression) # Note: Use safely in production
return f"The result is {result}"
except:
return "Invalid expression"
Create tool instances
tools = {"weather": dspy.Tool(weather), "calculator": dspy.Tool(calculator)}
Create predictor
predictor = dspy.Predict(ToolSignature)
Make a prediction
response = predictor(
question="What's the weather in New York?", tools=list(tools.values())
)
Execute the tool calls
for call in response.outputs.tool_calls:
# Execute the tool call
result = call.execute()
print(f"Tool: {call.name}")
print(f"Args: {call.args}")
# print(f"Result: {result}")
This is the code that is present in the documentation. It is itself not working, giving the below error.
AttributeError Traceback (most recent call last)
Cell In[44], line 40
37 # Execute the tool calls
38 for call in response.outputs.tool_calls:
39 # Execute the tool call
---> 40 result = call.execute()
41 print(f"Tool: {call.name}")
42 print(f"Args: {call.args}")
