Ace Eldeib	4be2f9d75a	fix: numerous broken documentation links (#2070 ) seems linkchecker isn't catching them because it runs on generated html. at that point the links are already missing. the generation process seems to strip invalid references when they can't be re-written from md to html. I used https://github.com/tcort/markdown-link-check to check the doc source directly. There are a few false positives on localhost for development.	1 year ago

hitoshi44	3cf493b089	Fix Document & Expose StringPromptTemplate as a custom-prompt-template. (#1753 ) Regarding [this issue](https://github.com/hwchase17/langchain/issues/1754), the code in the document [Creating a custom prompt template](https://langchain.readthedocs.io/en/latest/modules/prompts/examples/custom_prompt_template.html) is no longer functional and outdated. To address this, I have made the following changes: 1. Updated the guide in the document to use `StringPromptTemplate` instead of `BasePromptTemplate`. 2. Exposed `StringPromptTemplate` in `prompts/__init__.py` for easier importing.	2 years ago
hung_ng__	3d6fcb85dc	Add load json prompt example (#1776 ) Hi, I just want to add a PR on the prompt serialization examples of loading from JSON so that it can contain the same as loading from YAML.	2 years ago
jerwelborn	55efbb8a7e	pydantic/json parsing (#1722 ) ``` class Joke(BaseModel): setup: str = Field(description="question to set up a joke") punchline: str = Field(description="answer to resolve the joke") joke_query = "Tell me a joke." # Or, an example with compound type fields. #class FloatArray(BaseModel): # values: List[float] = Field(description="list of floats") # #float_array_query = "Write out a few terms of fiboacci." model = OpenAI(model_name='text-davinci-003', temperature=0.0) parser = PydanticOutputParser(pydantic_object=Joke) prompt = PromptTemplate( template="Answer the user query.\n{format_instructions}\n{query}\n", input_variables=["query"], partial_variables={"format_instructions": parser.get_format_instructions()} ) _input = prompt.format_prompt(query=joke_query) print("Prompt:\n", _input.to_string()) output = model(_input.to_string()) print("Completion:\n", output) parsed_output = parser.parse(output) print("Parsed completion:\n", parsed_output) ``` ``` Prompt: Answer the user query. The output should be formatted as a JSON instance that conforms to the JSON schema below. For example, the object {"foo": ["bar", "baz"]} conforms to the schema {"foo": {"description": "a list of strings field", "type": "string"}}. Here is the output schema: --- {"setup": {"description": "question to set up a joke", "type": "string"}, "punchline": {"description": "answer to resolve the joke", "type": "string"}} --- Tell me a joke. Completion: {"setup": "Why don't scientists trust atoms?", "punchline": "Because they make up everything!"} Parsed completion: setup="Why don't scientists trust atoms?" punchline='Because they make up everything!' ``` Ofc, works only with LMs of sufficient capacity. DaVinci is reliable but not always. --------- Co-authored-by: Harrison Chase <hw.chase.17@gmail.com>	2 years ago

Harrison Chase	df6c33d4b3	Harrison/new output parser (#1617 )	2 years ago
Jason Gill	1989e7d4c2	Update examples to prevent confusing missing _type warning (#1391 ) The YAML and JSON examples of prompt serialization now give a strange `No '_type' key found, defaulting to 'prompt'` message when you try to run them yourself or copy the format of the files. The reason for this harmless warning is that the _type key was not in the config files, which means they are parsed as a standard prompt. This could be confusing to new users (like it was confusing to me after upgrading from 0.0.85 to 0.0.86+ for my few_shot prompts that needed a _type added to the example_prompt config), so this update includes the _type key just for clarity. Obviously this is not critical as the warning is harmless, but it could be confusing to track down or be interpreted as an error by a new user, so this update should resolve that.	2 years ago

Amos Ng	8baf6fb920	Update examples to fix execution problems (#685 ) On the [Getting Started page](https://langchain.readthedocs.io/en/latest/modules/prompts/getting_started.html) for prompt templates, I believe the very last example ```python print(dynamic_prompt.format(adjective=long_string)) ``` should actually be ```python print(dynamic_prompt.format(input=long_string)) ``` The existing example produces `KeyError: 'input'` as expected * On the [Create a custom prompt template](https://langchain.readthedocs.io/en/latest/modules/prompts/examples/custom_prompt_template.html#id1) page, I believe the line ```python Function Name: {kwargs["function_name"]} ``` should actually be ```python Function Name: {kwargs["function_name"].__name__} ``` The existing example produces the prompt: ``` Given the function name and source code, generate an English language explanation of the function. Function Name: <function get_source_code at 0x7f907bc0e0e0> Source Code: def get_source_code(function_name): # Get the source code of the function return inspect.getsource(function_name) Explanation: ``` * On the [Example Selectors](https://langchain.readthedocs.io/en/latest/modules/prompts/examples/example_selectors.html) page, the first example does not define `example_prompt`, which is also subtly different from previous example prompts used. For user convenience, I suggest including ```python example_prompt = PromptTemplate( input_variables=["input", "output"], template="Input: {input}\nOutput: {output}", ) ``` in the code to be copy-pasted	2 years ago

Charles Frye	bfb23f4608	typo bugfixes in getting started with prompts (#651 ) tl;dr: input -> word, output -> antonym, rename to dynamic_prompt consistently The provided code in this example doesn't run, because the keys are `word` and `antonym`, rather than `input` and `output`. Also, the `ExampleSelector`-based prompt is named `few_shot_prompt` when defined and `dynamic_prompt` in the follow-up example. The former name is less descriptive and collides with an earlier example, so I opted for the latter. Thanks for making a really cool library!	2 years ago

Harrison Chase	985496f4be	Docs refactor (#480 ) Big docs refactor! Motivation is to make it easier for people to find resources they are looking for. To accomplish this, there are now three main sections: - Getting Started: steps for getting started, walking through most core functionality - Modules: these are different modules of functionality that langchain provides. Each part here has a "getting started", "how to", "key concepts" and "reference" section (except in a few select cases where it didnt easily fit). - Use Cases: this is to separate use cases (like summarization, question answering, evaluation, etc) from the modules, and provide a different entry point to the code base. There is also a full reference section, as well as extra resources (glossary, gallery, etc) Co-authored-by: Shreya Rajpal <ShreyaR@users.noreply.github.com>	2 years ago
