Zander Chase	429f4dbe4d	Add Input Mapper in run_on_dataset (#6894 ) If you create a dataset from runs and run the same chain or llm on it later, it usually works great. If you have an agent dataset and want to run a different agent on it, or have more complex schema, it's hard for us to automatically map these values every time. This PR lets you pass in an input_mapper function that converts the example inputs to whatever format your model expects	1 year ago
corranmac	20c6ade2fc	Grobid parser for Scientific Articles from PDF (#6729 ) ### Scientific Article PDF Parsing via Grobid `Description:` This change adds the GrobidParser class, which uses the Grobid library to parse scientific articles into a universal XML format containing the article title, references, sections, section text etc. The GrobidParser uses a local Grobid server to return PDFs document as XML and parses the XML to optionally produce documents of individual sentences or of whole paragraphs. Metadata includes the text, paragraph number, pdf relative bboxes, pages (text may overlap over two pages), section title (Introduction, Methodology etc), section_number (i.e 1.1, 2.3), the title of the paper and finally the file path. Grobid parsing is useful beyond standard pdf parsing as it accurately outputs sections and paragraphs within them. This allows for post-fitering of results for specific sections i.e. limiting results to the methodology section or results. While sections are split via headings, ideally they could be classified specifically into introduction, methodology, results, discussion, conclusion. I'm currently experimenting with chatgpt-3.5 for this function, which could later be implemented as a textsplitter. `Dependencies:` For use, the grobid repo must be cloned and Java must be installed, for colab this is: ``` !apt-get install -y openjdk-11-jdk -q !update-alternatives --set java /usr/lib/jvm/java-11-openjdk-amd64/bin/java !git clone https://github.com/kermitt2/grobid.git os.environ["JAVA_HOME"] = "/usr/lib/jvm/java-11-openjdk-amd64" os.chdir('grobid') !./gradlew clean install ``` Once installed the server is ran on localhost:8070 via ``` get_ipython().system_raw('nohup ./gradlew run > grobid.log 2>&1 &') ``` @rlancemartin, @eyurtsev Twitter Handle: @Corranmac Grobid Demo Notebook is [here](https://colab.research.google.com/drive/1X-St_mQRmmm8YWtct_tcJNtoktbdGBmd?usp=sharing). --------- Co-authored-by: rlm <pexpresss31@gmail.com>	1 year ago

Cristóbal Carnero Liñán	e494b0a09f	feat (documents): add a source code loader based on AST manipulation (#6486 ) #### Summary A new approach to loading source code is implemented: Each top-level function and class in the code is loaded into separate documents. Then, an additional document is created with the top-level code, but without the already loaded functions and classes. This could improve the accuracy of QA chains over source code. For instance, having this script: ``` class MyClass: def __init__(self, name): self.name = name def greet(self): print(f"Hello, {self.name}!") def main(): name = input("Enter your name: ") obj = MyClass(name) obj.greet() if __name__ == '__main__': main() ``` The loader will create three documents with this content: First document: ``` class MyClass: def __init__(self, name): self.name = name def greet(self): print(f"Hello, {self.name}!") ``` Second document: ``` def main(): name = input("Enter your name: ") obj = MyClass(name) obj.greet() ``` Third document: ``` # Code for: class MyClass: # Code for: def main(): if __name__ == '__main__': main() ``` A threshold parameter is added to control whether small scripts are split in this way or not. At this moment, only Python and JavaScript are supported. The appropriate parser is determined by examining the file extension. #### Tests This PR adds: - Unit tests - Integration tests #### Dependencies Only one dependency was added as optional (needed for the JavaScript parser). #### Documentation A notebook is added showing how the loader can be used. #### Who can review? @eyurtsev @hwchase17 --------- Co-authored-by: rlm <pexpresss31@gmail.com>	1 year ago

Alejandra De Luna	980c865174	fix: remove callbacks arg from Tool and StructuredTool inferred schema (#6483 ) Fixes #5456 This PR removes the `callbacks` argument from a tool's schema when creating a `Tool` or `StructuredTool` with the `from_function` method and `infer_schema` is set to `True`. The `callbacks` argument is now removed in the `create_schema_from_function` and `_get_filtered_args` methods. As suggested by @vowelparrot, this fix provides a straightforward solution that minimally affects the existing implementation. A test was added to verify that this change enables the expected use of `Tool` and `StructuredTool` when using a `CallbackManager` and inferring the tool's schema. - @hwchase17	1 year ago

Tim Conkling	c28990d871	StreamlitCallbackHandler (#6315 ) A new implementation of `StreamlitCallbackHandler`. It formats Agent thoughts into Streamlit expanders. You can see the handler in action here: https://langchain-mrkl.streamlit.app/ Per a discussion with Harrison, we'll be adding a `StreamlitCallbackHandler` implementation to an upcoming [Streamlit](https://github.com/streamlit/streamlit) release as well, and will be updating it as we add new LLM- and LangChain-specific features to Streamlit. The idea with this PR is that the LangChain `StreamlitCallbackHandler` will "auto-update" in a way that keeps it forward- (and backward-) compatible with Streamlit. If the user has an older Streamlit version installed, the LangChain `StreamlitCallbackHandler` will be used; if they have a newer Streamlit version that has an updated `StreamlitCallbackHandler`, that implementation will be used instead. (I'm opening this as a draft to get the conversation going and make sure we're on the same page. We're really excited to land this into LangChain!) #### Who can review? @agola11, @hwchase17	1 year ago
