Getting error: AttributeError: 'str' object has no attribute 'id'

I am trying to create a simple custom function and calling from agent as part of tools getting below error:

Hey @anshul.mittal, can you please share your code so I can help you better with debugging?

Hi @manthanguptaa ,

Code:

from phi.agent import Agent, RunResponse
from phi.model.huggingface import HuggingFaceChat
import oci

def sum(a: int, b: int) → str:
“Sum of a and b”
return str(a+b)

#meta-llama/Meta-Llama-3-8B-Instruct,mistralai/Mixtral-8x7B-Instruct-v0.1, microsoft/Phi-3.5-mini-instruct

agent = Agent(
model=HuggingFaceChat(
id=“meta-llama/Meta-Llama-3-8B-Instruct”,
#max_tokens=1024,
api_key=‘***’
),
tools=[sum],
show_tool_calls= True,
markdown=True,
debug_mode=True,
reasoning=True,
)

Print the response on the terminal

agent.print_response(“calculate the sum of 2 and 4”,stream=True)

So to create your own custom tools you have to follow this doc

Your correct implementation won’t work with it

I followed the document, still the same issue. my code is now as below:

from phi.agent import Agent, RunResponse
from phi.model.huggingface import HuggingFaceChat
from phi.tools import Toolkit
import oci

class IamTools(Toolkit):

def __init__(self):
    super().__init__(name="IamTools")
    #self.register(self.get_User_Details)
    self.register(self.sum)

# def get_User_Details() -> str: 
#     config = oci.config.from_file ("C:\\oci\\config", "DEFAULT")
#     identity = oci.identity.IdentityClient(config) 
#     user = identity.get_user(config["user"]).data    
#     return str(user)

def sum(a: int, b: int) -> str:
    "Sum of a and b"
    return str(a+b)

#meta-llama/Meta-Llama-3-8B-Instruct,mistralai/Mixtral-8x7B-Instruct-v0.1, microsoft/Phi-3.5-mini-instruct

agent = Agent(
model=HuggingFaceChat(
id=“meta-llama/Meta-Llama-3-8B-Instruct”,
max_tokens=1024,
api_key=‘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’
),
tools=[IamTools()],
show_tool_calls= True,
markdown=True,
debug_mode=True,
reasoning=True,
instructions=[“output in table form”]
)

Print the response on the terminal

agent.print_response(“how to find permission inherited from other compartments in OCI IAM for particular user, provide the programming syntax in python and execute the code”)
agent.print_response(“calculate the sum of 2 and 4”,stream=True)
agent.print_response(“get user details”,stream=True)

@anshul.mittal there is some issue with HuggingFaceChat class on our end and we are on it to fix it. Follow this github issue Error when using Hugginface Inference API with Phidata tools · Issue #1618 · phidatahq/phidata · GitHub

Thanks @manthanguptaa for an update.
