This and your previous video have been great! But I started following you based on your Flowise videos and now I use Flowise a lot for production work as well. Are you going to make a Flowise version of your videos based on these videos at all? Don't forget your Flowise followers 😉

@leonvanzyl Жыл бұрын

I have not forgotten about Flowise at all, don't worry. I am literally working on an updating Flowise tutorial series, as we speak. A lot has changed since that original series.

Hi, great video! I was wondering, would it be fine if we just got the string from the content of the AI Message Object instead of using a parser? I noticed everyone uses parsers for this but I'm not sure why yet. Thanks!

I am trying to follow your tutorial. When I am writing the statement "parser = JsonOutputPaser(pydantic_object=Person)", there is no "pydantic_object" although I can find "pydantic" and "pydantic_core", should I use "pydantic" instead?

@rogerwmwong 8 ай бұрын

I tried "parser = JsonOutputParser(pydantic=Person)" and it works! Thanks!

I am trying to extract 3rd field as address from my prompt apart from name and age. But I am not getting any output why? Is it because we can only output two fields from the json parser?

@leonvanzyl 8 ай бұрын

There is no limit to the amount of fields. Ensure that your system prompt as well as the output parser have the 3rd field in them.

@@leonvanzyl I am using this function def call_json_output_parser(): prompt = ChatPromptTemplate.from_messages([ ("system", "Extract information from following phrase. Formatting instruction: {format_instruction}"), ("human","{phrase}") ]) class Person(BaseModel): name: str = Field(description = "name of the person") age : int = Field(description = "age of the person") address: str = Field(description = "address of the person") parser = JsonOutputParser(pydantic_object=Person) chain = prompt | llm | parser return chain.invoke({ "phrase":"Max is thirty years old. He lives in 492, Kamal Market, Delhi. He studies in Convent school.", "format_instruction":parser.get_format_instructions() }) After printing this I am not getting any output. consol output is this {'properties': {'name': {'title': 'Name', 'description': 'name of the person', 'type': 'string'}, 'age': {'title': 'Age', 'description': 'age of the person', 'type': 'integer'}, 'address': {'title': 'Address', 'description': 'address of the person', 'type': 'string'}}, 'required': ['name', 'age', 'address']} However If I am commenting address field from the pydantic, I am able to print age and name. Not sure where I am making the mistake
