794c869f24fb-7 | this movie has a special place in the heart of Mr. Bogdanovich- he even bought it back from its producers, then distributed it on his own and went bankrupt when it didn\'t prove popular. His rise and fall is among the more sympathetic and tragic of Hollywood stories, so there\'s no joy in criticizing the film... there _is_ real emotional investment in Ms. Stratten\'s scenes. But "Laughed" is a faint echo of "The Last Picture Show", "Paper Moon" or "What\'s Up, Doc"- following "Daisy Miller" and "At Long Last Love", it was a thundering confirmation of the phase from which P.B. has never emerged.<br /><br />All in all, though, the movie is harmless, only a waste of rental. I want to watch people having a good time, I\'ll go to the park on a sunny day.

794c869f24fb-8 | Document(page_content="This is said to be a personal film for Peter Bogdonavitch. He based it on his life but changed things around to fit the characters, who are detectives. These detectives date beautiful models and have no problem getting them. Sounds more like a millionaire playboy filmmaker than a detective, doesn't it? This entire movie was written by Peter, and it shows how out of touch with real people he was. You're supposed to write what you know, and he did that, indeed. And leaves the audience bored and confused, and jealous, for that matter. This is a curio for people who want to see Dorothy Stratten, who was murdered right after filming. But Patti Hanson, who would, in real life, marry Keith Richards, was also a model, like Stratten, but is a lot better and has a more ample part. In fact, Stratten's part seemed forced; added. She doesn't have a lot to do with the story, which is pretty convoluted to begin with. All in all, every character in this film is somebody that very few people can relate with, unless you're millionaire from Manhattan with beautiful supermodels at your beckon call. For the rest of us, it's an irritating snore fest. That's what happens when you're out of touch. You entertain your few friends with inside jokes, and bore all the rest.", metadata={'label': 0}), | https://python.langchain.com/docs/integrations/document_loaders/hugging_face_dataset |
794c869f24fb-9 | Document(page_content='It was great to see some of my favorite stars of 30 years ago including John Ritter, Ben Gazarra and Audrey Hepburn. They looked quite wonderful. But that was it. They were not given any characters or good lines to work with. I neither understood or cared what the characters were doing.<br /><br />Some of the smaller female roles were fine, Patty Henson and Colleen Camp were quite competent and confident in their small sidekick parts. They showed some talent and it is sad they didn\'t go on to star in more and better films. Sadly, I didn\'t think Dorothy Stratten got a chance to act in this her only important film role.<br /><br />The film appears to have some fans, and I was very open-minded when I started watching it. I am a big Peter Bogdanovich fan and I enjoyed his last movie, "Cat\'s Meow" and all his early ones from "Targets" to "Nickleodeon". So, it really surprised me that I was barely able to keep awake watching this one.<br /><br />It is ironic that this movie is about a detective agency where the detectives and clients get romantically involved with each other. Five years later, Bogdanovich\'s ex-girlfriend, Cybil Shepherd had a hit television series called "Moonlighting" stealing the story idea from Bogdanovich. Of course, there was a great difference in that the series relied on tons of witty dialogue, while this tries to make do with slapstick and a few screwball lines.<br /><br />Bottom line: It ain\'t no "Paper Moon" and only a very pale version of "What\'s Up, Doc".', metadata={'label': 0}), | https://python.langchain.com/docs/integrations/document_loaders/hugging_face_dataset |

794c869f24fb-12 | Document(page_content='Today I found "They All Laughed" on VHS on sale in a rental. It was a really old and very used VHS, I had no information about this movie, but I liked the references listed on its cover: the names of Peter Bogdanovich, Audrey Hepburn, John Ritter and specially Dorothy Stratten attracted me, the price was very low and I decided to risk and buy it. I searched IMDb, and the User Rating of 6.0 was an excellent reference. I looked in "Mick Martin & Marsha Porter Video & DVD Guide 2003" and \x96 wow \x96 four stars! So, I decided that I could not waste more time and immediately see it. Indeed, I have just finished watching "They All Laughed" and I found it a very boring overrated movie. The characters are badly developed, and I spent lots of minutes to understand their roles in the story. The plot is supposed to be funny (private eyes who fall in love for the women they are chasing), but I have not laughed along the whole story. The coincidences, in a huge city like New York, are ridiculous. Ben Gazarra as an attractive and very seductive man, with the women falling for him as if her were a Brad Pitt, Antonio Banderas or George Clooney, is quite ridiculous. In the end, the greater attractions certainly are the presence of the Playboy centerfold and playmate of the year Dorothy Stratten, murdered by her husband pretty after the release of this movie, and whose life was showed in "Star 80" and "Death of a Centerfold: The Dorothy Stratten Story"; the amazing beauty of the sexy Patti Hansen, the future Mrs. Keith Richards; the always wonderful, even being fifty-two years old, Audrey Hepburn; and the song "Amigo", from Roberto Carlos. Although I do not like him, Roberto Carlos has been the most popular Brazilian singer since the end of the 60\'s and is called by his fans as "The King". I will keep this movie in my collection only because of these attractions (manly Dorothy Stratten). My vote is four.<br /><br />Title (Brazil): "Muito Riso e Muita Alegria" ("Many Laughs and Lots of Happiness")', metadata={'label': 0})] | https://python.langchain.com/docs/integrations/document_loaders/hugging_face_dataset |

I just bought it last week.\nI restored as manufactures cleaned up the screen\nthe problem continues\n\n## 27 Answers\n\nFilter by: \n\nMost Helpful\nNewest\nOldest\n\n### Accepted Answer\nHi,\nWhere did you buy it? If you bought it from Apple or from an official retailer like Carphone warehouse etc. Then you\'ll have a year warranty and can get it replaced free.\nIf you bought it second hand, from a third part repair shop or online, then it may still have warranty, unless it is refurbished and has been repaired elsewhere.\nIf this is the case, it may be the screen that needs replacing to solve your issue.\nEither way, wherever you got it, it\'s best to return it and get a refund or a replacement device. :-)\n\n\n\n### Most Helpful Answer\nI had the same issues, screen freezing, opening apps by itself, selecting the screens and typing on it\'s own. I first suspected aliens and then ghosts and then hackers.\niPhone 6 is weak physically and tend to bend on pressure. And my phone had no case or cover.\nI took the phone to apple stores and they said sensors need to be replaced and possibly screen replacement as well. My phone is just 17 months old.\nHere is what I did two days ago and since then it is working like a charm..\nHold the phone in portrait (as if watching a movie). Twist it very very gently. do it few times.Rest the phone for 10 mins (put it on a flat surface). You can now notice those self typing things gone and screen getting stabilized.\nThen, reset the hardware (hold the power and home button till the screen goes off and comes back with apple logo). release the buttons when you see this.\nThen, connect to your laptop and log in to iTunes and reset your phone completely. (please take a back-up first).\nAnd your phone should be good to use again.\nWhat really happened here for me is that the sensors might have stuck to the screen and with mild twisting, they got disengaged/released.\nI posted this in Apple Community and the moderators deleted it, for the best reasons known to them.\nInstead | https://python.langchain.com/docs/integrations/document_loaders/ifixit |
a7401bb3db28-2 | this in Apple Community and the moderators deleted it, for the best reasons known to them.\nInstead of throwing away your phone (or selling cheaply), try this and you could be saving your phone.\nLet me know how it goes.\n\n\n\n### Other Answer\nIt was the charging cord! I bought a gas station braided cord and it was the culprit. Once I plugged my OEM cord into the phone the GHOSTS went away.\n\n\n\n### Other Answer\nI\'ve same issue that I just get resolved. I first tried to restore it from iCloud back, however it was not a software issue or any virus issue, so after restore same problem continues. Then I get my phone to local area iphone repairing lab, and they detected that it is an LCD issue. LCD get out of order without any reason (It was neither hit or nor slipped, but LCD get out of order all and sudden, while using it) it started opening things at random. I get LCD replaced with new one, that cost me $80.00 in total ($70.00 LCD charges + $10.00 as labor charges to fix it). iPhone is back to perfect mode now. It was iphone 6s. Thanks.\n\n\n\n### Other Answer\nI was having the same issue with my 6 plus, I took it to a repair shop, they opened the phone, disconnected the three ribbons the screen has, blew up and cleaned the connectors and connected the screen again and it solved the issue… it’s hardware, not software.\n\n\n\n### Other Answer\nHey.\nJust had this problem now. As it turns out, you just need to plug in your phone. I use a case and when I took it off I noticed that there was a lot of dust and dirt around the areas that the case didn\'t cover. I shined a light in my ports and noticed they were filled with dust. Tomorrow I plan on using pressurized air to clean it out and the problem should be solved. If you plug in your phone and unplug it and it stops the issue, I recommend cleaning your phone thoroughly.\n\n\n\n### Other Answer\nI simply changed the power supply and problem was gone. The block that plugs in the wall not the sub cord. The cord was fine but not the block.\n\n\n\n### Other Answer\nSomeone ask! I purchased my iPhone 6s Plus | https://python.langchain.com/docs/integrations/document_loaders/ifixit |
a7401bb3db28-3 | Other Answer\nSomeone ask! I purchased my iPhone 6s Plus for 1000 from at&t. Before I touched it, I purchased a otter defender case. I read where at&t said touch desease was due to dropping! Bullshit!! I am 56 I have never dropped it!! Looks brand new! Never dropped or abused any way! I have my original charger. I am going to clean it and try everyone’s advice. It really sucks! I had 40,000,000 on my heart of Vegas slots! I play every day. I would be spinning and my fingers were no where max buttons and it would light up and switch to max. It did it 3 times before I caught it light up by its self. It sucks. Hope I can fix it!!!!\n\n\n\n### Other Answer\nNo answer, but same problem with iPhone 6 plus--random, self-generated jumping amongst apps and typing on its own--plus freezing regularly (aha--maybe that\'s what the "plus" in "6 plus" refers to?). An Apple Genius recommended upgrading to iOS 11.3.1 from 11.2.2, to see if that fixed the trouble. If it didn\'t, Apple will sell me a new phone for $168! Of couese the OS upgrade didn\'t fix the problem. Thanks for helping me figure out that it\'s most likely a hardware problem--which the "genius" probably knows too.\nI\'m getting ready to go Android.\n\n\n\n### Other Answer\nI experienced similar ghost touches. Two weeks ago, I changed my iPhone 6 Plus shell (I had forced the phone into it because it’s pretty tight), and also put a new glass screen protector (the edges of the protector don’t stick to the screen, weird, so I brushed pressure on the edges at times to see if they may smooth out one day miraculously). I’m not sure if I accidentally bend the phone when I installed the shell, or, if I got a defective glass protector that messes up the touch sensor. Well, yesterday was the worse day, keeps dropping calls and ghost pressing keys for me when I was on a call. I got fed up, so I removed the screen protector, and so far problems have not reoccurred yet. I’m crossing my fingers that problems indeed solved.\n\n\n\n### Other Answer\nthank you so much | https://python.langchain.com/docs/integrations/document_loaders/ifixit |
a7401bb3db28-4 | crossing my fingers that problems indeed solved.\n\n\n\n### Other Answer\nthank you so much for this post! i was struggling doing the reset because i cannot type userids and passwords correctly because the iphone 6 plus i have kept on typing letters incorrectly. I have been doing it for a day until i come across this article. Very helpful! God bless you!!\n\n\n\n### Other Answer\nI just turned it off, and turned it back on.\n\n\n\n### Other Answer\nMy problem has not gone away completely but its better now i changed my charger and turned off prediction ....,,,now it rarely happens\n\n\n\n### Other Answer\nI tried all of the above. I then turned off my home cleaned it with isopropyl alcohol 90%. Then I baked it in my oven on warm for an hour and a half over foil. Took it out and set it cool completely on the glass top stove. Then I turned on and it worked.\n\n\n\n### Other Answer\nI think at& t should man up and fix your phone for free! You pay a lot for a Apple they should back it. I did the next 30 month payments and finally have it paid off in June. My iPad sept. Looking forward to a almost 100 drop in my phone bill! Now this crap!!! Really\n\n\n\n### Other Answer\nIf your phone is JailBroken, suggest downloading a virus. While all my symptoms were similar, there was indeed a virus/malware on the phone which allowed for remote control of my iphone (even while in lock mode). My mistake for buying a third party iphone i suppose. Anyway i have since had the phone restored to factory and everything is working as expected for now. I will of course keep you posted if this changes. Thanks to all for the helpful posts, really helped me narrow a few things down.\n\n\n\n### Other Answer\nWhen my phone was doing this, it ended up being the screen protector that i got from 5 below. I took it off and it stopped. I ordered more protectors from amazon and replaced it\n\n\n\n### Other Answer\niPhone 6 Plus first generation….I had the same issues as all above, apps opening by themselves, self typing, ultra sensitive screen, items jumping around all over….it even called someone on FaceTime twice by itself when I was not in the room…..I thought the phone was toast | https://python.langchain.com/docs/integrations/document_loaders/ifixit |
a7401bb3db28-5 | on FaceTime twice by itself when I was not in the room…..I thought the phone was toast and i’d have to buy a new one took me a while to figure out but it was the extra cheap block plug I bought at a dollar store for convenience of an extra charging station when I move around the house from den to living room…..cord was fine but bought a new Apple brand block plug…no more problems works just fine now. This issue was a recent event so had to narrow things down to what had changed recently to my phone so I could figure it out.\nI even had the same problem on a laptop with documents opening up by themselves…..a laptop that was plugged in to the same wall plug as my phone charger with the dollar store block plug….until I changed the block plug.\n\n\n\n### Other Answer\nHad the problem: Inherited a 6s Plus from my wife. She had no problem with it.\nLooks like it was merely the cheap phone case I purchased on Amazon. It was either pinching the edges or torquing the screen/body of the phone. Problem solved.\n\n\n\n### Other Answer\nI bought my phone on march 6 and it was a brand new, but It sucks me uo because it freezing, shaking and control by itself. I went to the store where I bought this and I told them to replacr it, but they told me I have to pay it because Its about lcd issue. Please help me what other ways to fix it. Or should I try to remove the screen or should I follow your step above.\n\n\n\n### Other Answer\nI tried everything and it seems to come back to needing the original iPhone cable…or at least another 1 that would have come with another iPhone…not the $5 Store fast charging cables. My original cable is pretty beat up - like most that I see - but I’ve been beaten up much MUCH less by sticking with its use! I didn’t find that the casing/shell around it or not made any diff.\n\n\n\n### Other Answer\ngreat now I have to wait one more hour to reset my phone and while I was tryin to connect my phone to my computer the computer also restarted smh does anyone else knows how I can get my phone to work… my problem is I have a black dot on the bottom left of my screen an it wont allow me to touch a certain part of my | https://python.langchain.com/docs/integrations/document_loaders/ifixit |

I got it replaced at local repair shop, so far phone is working fine.\n\n\n\n### Other Answer\nthis problem in iphone 6 has many different scenarios and solutions, first try to reconnect the lcd screen to the motherboard again, if didnt solve, try to replace the lcd connector on the motherboard, if not solved, then remains two issues, lcd screen it self or touch IC. in my country some repair shops just change them all for almost 40$ since they dont want to troubleshoot one by one. readers of this comment also should know that partial screen not responding in other iphone models might also have an issue in LCD connector on the motherboard, specially if you lock/unlock screen and screen works again for sometime. lcd connectors gets disconnected lightly from the motherboard due to multiple falls and hits after sometime. best of luck for all\n\n\n\n### Other Answer\nI am facing the same issue whereby these ghost touches type and open apps , I am using an original Iphone cable , how to I fix this issue.\n\n\n\n### Other Answer\nThere were two issues with the phone I had troubles with. It was my dads and turns out he carried it in his pocket. The phone itself had a little bend in it as a result. A little pressure in the opposite direction helped the issue. But it also had a tiny crack in the screen which wasnt obvious, once we added a screen protector this fixed the issues entirely.\n\n\n\n### Other Answer\nI had the same problem with my 64Gb iPhone 6+.

32997273a63a-0 | This notebook covers how to load data from the Iugu REST API into a format that can be ingested into LangChain, along with example usage for vectorization.
The Iugu API requires an access token, which can be found inside of the Iugu dashboard.
This document loader also requires a resource option which defines what data you want to load.
# Create a vectorstore retriever from the loader
# see https://python.langchain.com/en/latest/modules/data_connection/getting_started.html for more details
index = VectorstoreIndexCreator().from_loaders([iugu_loader])
iugu_doc_retriever = index.vectorstore.as_retriever() | https://python.langchain.com/docs/integrations/document_loaders/iugu |
b881a517ad70-0 | This notebook covers how to load documents from a Joplin database.
Joplin has a REST API for accessing its local database. This loader uses the API to retrieve all notes in the database and their metadata. This requires an access token that can be obtained from the app by following these steps:
You may either initialize the loader directly with the access token, or store it in the environment variable JOPLIN_ACCESS_TOKEN.
An alternative to this approach is to export the Joplin's note database to Markdown files (optionally, with Front Matter metadata) and use a Markdown loader, such as ObsidianLoader, to load them.
from langchain.document_loaders import JoplinLoader | https://python.langchain.com/docs/integrations/document_loaders/joplin |

a3d492b839b3-0 | Wikipedia
Wikipedia is a multilingual free online encyclopedia written and maintained by a community of volunteers, known as Wikipedians, through open collaboration and using a wiki-based editing system called MediaWiki. Wikipedia is the largest and most-read reference work in history.
This notebook shows how to load wiki pages from wikipedia.org into the Document format that we use downstream.
Installation
First, you need to install wikipedia python package.
Examples
WikipediaLoader has these arguments:
query: free text which used to find documents in Wikipedia
optional lang: default="en". Use it to search in a specific language part of Wikipedia
optional load_max_docs: default=100. Use it to limit number of downloaded documents. It takes time to download all 100 documents, so use a small number for experiments. There is a hard limit of 300 for now.
optional load_all_available_meta: default=False. By default only the most important fields downloaded: Published (date when document was published/last updated), title, Summary. If True, other fields also downloaded.
from langchain.document_loaders import WikipediaLoader
docs = WikipediaLoader(query="HUNTER X HUNTER", load_max_docs=2).load()
len(docs)
docs[0].metadata # meta-information of the Document
docs[0].page_content[:400] # a content of the Document | https://python.langchain.com/docs/integrations/document_loaders/wikipedia |
04e7c1b8ee94-0 | The UnstructuredXMLLoader is used to load XML files. The loader works with .xml files. The page content will be the text extracted from the XML tags.
Document(page_content='United States\n\nWashington, DC\n\nJoe Biden\n\nBaseball\n\nCanada\n\nOttawa\n\nJustin Trudeau\n\nHockey\n\nFrance\n\nParis\n\nEmmanuel Macron\n\nSoccer\n\nTrinidad & Tobado\n\nPort of Spain\n\nKeith Rowley\n\nTrack & Field', metadata={'source': 'example_data/factbook.xml'}) | https://python.langchain.com/docs/integrations/document_loaders/xml |
2dde515b2ac9-0 | WebBaseLoader
This covers how to use WebBaseLoader to load all text from HTML webpages into a document format that we can use downstream. For more custom logic for loading webpages look at some child class examples such as IMSDbLoader, AZLyricsLoader, and CollegeConfidentialLoader
from langchain.document_loaders import WebBaseLoader
loader = WebBaseLoader("https://www.espn.com/")
To bypass SSL verification errors during fetching, you can set the "verify" option:
loader.requests_kwargs = {'verify':False} | https://python.langchain.com/docs/integrations/document_loaders/web_base |

2de642293749-0 | Cassandra Chat Message History
Apache Cassandra® is a NoSQL, row-oriented, highly scalable and highly available database, well suited for storing large amounts of data.
Cassandra is a good choice for storing chat message history because it is easy to scale and can handle a large number of writes.
This notebook goes over how to use Cassandra to store chat message history.
To run this notebook you need either a running Cassandra cluster or a DataStax Astra DB instance running in the cloud (you can get one for free at datastax.com). Check cassio.org for more information.
pip install "cassio>=0.0.7"
Please provide database connection parameters and secrets:

database_mode = (input("\n(C)assandra or (A)stra DB? ")).upper()
keyspace_name = input("\nKeyspace name? ")
if database_mode == "A":
ASTRA_DB_APPLICATION_TOKEN = getpass.getpass('\nAstra DB Token ("AstraCS:...") ')

ASTRA_DB_SECURE_BUNDLE_PATH = input("Full path to your Secure Connect Bundle? ")
elif database_mode == "C":
CASSANDRA_CONTACT_POINTS = input(
"Contact points? (comma-separated, empty for localhost) "

551477b2a5b0-0 | Building chat or QA applications on YouTube videos is a topic of high interest.
Below we show how to easily go from a YouTube url to text to chat!
We wil use the OpenAIWhisperParser, which will use the OpenAI Whisper API to transcribe audio to text, and the OpenAIWhisperParserLocal for local support and running on private clouds or on premise.
Note: You will need to have an OPENAI_API_KEY supplied.
from langchain.document_loaders.generic import GenericLoader
from langchain.document_loaders.parsers import OpenAIWhisperParser, OpenAIWhisperParserLocal
from langchain.document_loaders.blob_loaders.youtube_audio import YoutubeAudioLoader
We will use yt_dlp to download audio for YouTube urls.
We will use pydub to split downloaded audio files (such that we adhere to Whisper API's 25MB file size limit).
pip install yt_dlp
pip install pydub
pip install librosa
YouTube url to text
Use YoutubeAudioLoader to fetch / download the audio files.
Then, ues OpenAIWhisperParser() to transcribe them to text.
Let's take the first lecture of Andrej Karpathy's YouTube course as an example!
# set a flag to switch between local and remote parsing
# change this to True if you want to use local parsing
local = False
# Two Karpathy lecture videos
urls = ["https://youtu.be/kCc8FmEb1nY", "https://youtu.be/VMj-3S1tku0"]

551477b2a5b0-3 | qa_chain.run(query)
"We need to zero out the gradient before backprop at each step because the backward pass accumulates gradients in the grad attribute of each parameter. If we don't reset the grad to zero before each backward pass, the gradients will accumulate and add up, leading to incorrect updates and slower convergence. By resetting the grad to zero before each backward pass, we ensure that the gradients are calculated correctly and that the optimization process works as intended."
query = "What is the difference between an encoder and decoder?"
qa_chain.run(query)
'In the context of transformers, an encoder is a component that reads in a sequence of input tokens and generates a sequence of hidden representations. On the other hand, a decoder is a component that takes in a sequence of hidden representations and generates a sequence of output tokens. The main difference between the two is that the encoder is used to encode the input sequence into a fixed-length representation, while the decoder is used to decode the fixed-length representation into an output sequence. In machine translation, for example, the encoder reads in the source language sentence and generates a fixed-length representation, which is then used by the decoder to generate the target language sentence.'
query = "For any token, what are x, k, v, and q?"
qa_chain.run(query)
'For any token, x is the input vector that contains the private information of that token, k and q are the key and query vectors respectively, which are produced by forwarding linear modules on x, and v is the vector that is calculated by propagating the same linear module on x again. The key vector represents what the token contains, and the query vector represents what the token is looking for. The vector v is the information that the token will communicate to other tokens if it finds them interesting, and it gets aggregated for the purposes of the self-attention mechanism.' | https://python.langchain.com/docs/integrations/document_loaders/youtube_audio |
a95e8662ba47-0 | Dynamodb Chat Message History
This notebook goes over how to use Dynamodb to store chat message history.
First make sure you have correctly configured the AWS CLI. Then make sure you have installed boto3.
Next, create the DynamoDB Table where we will be storing messages:
import boto3
# Get the service resource.
dynamodb = boto3.resource("dynamodb")
# Create the DynamoDB table.
table = dynamodb.create_table(
TableName="SessionTable",
KeySchema=[{"AttributeName": "SessionId", "KeyType": "HASH"}],
AttributeDefinitions=[{"AttributeName": "SessionId", "AttributeType": "S"}],
BillingMode="PAY_PER_REQUEST",
)
# Wait until the table exists.
table.meta.client.get_waiter("table_exists").wait(TableName="SessionTable")
# Print out some data about the table.
print(table.item_count)
DynamoDBChatMessageHistory
from langchain.memory.chat_message_histories import DynamoDBChatMessageHistory
history = DynamoDBChatMessageHistory(table_name="SessionTable", session_id="0")
history.add_user_message("hi!")
history.add_ai_message("whats up?")
[HumanMessage(content='hi!', additional_kwargs={}, example=False),
AIMessage(content='whats up?', additional_kwargs={}, example=False),
HumanMessage(content='hi!', additional_kwargs={}, example=False),
AIMessage(content='whats up?', additional_kwargs={}, example=False)]
DynamoDBChatMessageHistory with Custom Endpoint URL
Sometimes it is useful to specify the URL to the AWS endpoint to connect to. For instance, when you are running locally against Localstack. For those cases you can specify the URL via the endpoint_url parameter in the constructor.
from langchain.memory.chat_message_histories import DynamoDBChatMessageHistory | https://python.langchain.com/docs/integrations/memory/dynamodb_chat_message_history |
a95e8662ba47-1 | history = DynamoDBChatMessageHistory(
table_name="SessionTable",
session_id="0",
endpoint_url="http://localhost.localstack.cloud:4566",
)
DynamoDBChatMessageHistory With Different Keys Composite Keys
The default key for DynamoDBChatMessageHistory is {"SessionId": self.session_id}, but you can modify this to match your table design.
Primary Key Name
You may modify the primary key by passing in a primary_key_name value in the constructor, resulting in the following: {self.primary_key_name: self.session_id}
Composite Keys
When using an existing DynamoDB table, you may need to modify the key structure from the default of to something including a Sort Key. To do this you may use the key parameter.
Passing a value for key will override the primary_key parameter, and the resulting key structure will be the passed value.
from langchain.memory.chat_message_histories import DynamoDBChatMessageHistory
composite_table = dynamodb.create_table(
TableName="CompositeTable",
KeySchema=[{"AttributeName": "PK", "KeyType": "HASH"}, {"AttributeName": "SK", "KeyType": "RANGE"}],
AttributeDefinitions=[{"AttributeName": "PK", "AttributeType": "S"}, {"AttributeName": "SK", "AttributeType": "S"}],
BillingMode="PAY_PER_REQUEST",
)
# Wait until the table exists.
composite_table.meta.client.get_waiter("table_exists").wait(TableName="CompositeTable")
# Print out some data about the table.
print(composite_table.item_count)
my_key = {
"PK": "session_id::0",
"SK": "langchain_history",
}
composite_key_history = DynamoDBChatMessageHistory(
table_name="CompositeTable",
session_id="0",
endpoint_url="http://localhost.localstack.cloud:4566",
key=my_key,
)
composite_key_history.add_user_message("hello, composite dynamodb table!")

By default, only the session id and message dictionary are stored in the table.
However, sometimes you might want to store some additional information, like message date, author, language etc.
To do that, you can create a custom message converter, by implementing BaseMessageConverter interface.

e422fec8c1b6-0 | Streamlit Chat Message History
This notebook goes over how to store and use chat message history in a Streamlit app. StreamlitChatMessageHistory will store messages in Streamlit session state at the specified key=. The default key is "langchain_messages".
Note, StreamlitChatMessageHistory only works when run in a Streamlit app.
You may also be interested in StreamlitCallbackHandler for LangChain.
For more on Streamlit check out their getting started documentation.
You can see the full app example running here, and more examples in github.com/langchain-ai/streamlit-agent.
from langchain.memory import StreamlitChatMessageHistory
history = StreamlitChatMessageHistory(key="chat_messages")
history.add_user_message("hi!")
history.add_ai_message("whats up?")
You can integrate StreamlitChatMessageHistory into ConversationBufferMemory and chains or agents as usual. The history will be persisted across re-runs of the Streamlit app within a given user session. A given StreamlitChatMessageHistory will NOT be persisted or shared across user sessions.
from langchain.memory import ConversationBufferMemory
from langchain.memory.chat_message_histories import StreamlitChatMessageHistory
# Optionally, specify your own session_state key for storing messages
msgs = StreamlitChatMessageHistory(key="special_app_key")
memory = ConversationBufferMemory(memory_key="history", chat_memory=msgs)
if len(msgs.messages) == 0:
msgs.add_ai_message("How can I help you?")
from langchain.chains import LLMChain
from langchain.llms import OpenAI
from langchain.prompts import PromptTemplate
template = """You are an AI chatbot having a conversation with a human.
{history}
Human: {human_input}
AI: """
prompt = PromptTemplate(input_variables=["history", "human_input"], template=template)
# Add the memory to an LLMChain as usual
llm_chain = LLMChain(llm=OpenAI(), prompt=prompt, memory=memory)
Conversational Streamlit apps will often re-draw each previous chat message on every re-run. This is easy to do by iterating through StreamlitChatMessageHistory.messages:
import streamlit as st
for msg in msgs.messages:
st.chat_message(msg.type).write(msg.content)
if prompt := st.chat_input():
st.chat_message("human").write(prompt) | https://python.langchain.com/docs/integrations/memory/streamlit_chat_message_history |
e422fec8c1b6-1 | if prompt := st.chat_input():
st.chat_message("human").write(prompt)
# As usual, new messages are added to StreamlitChatMessageHistory when the Chain is called.
response = llm_chain.run(prompt)
st.chat_message("ai").write(response)
View the final app. | https://python.langchain.com/docs/integrations/memory/streamlit_chat_message_history |
1e37ecfc94d3-0 | Xata chat memory
Xata is a serverless data platform, based on PostgreSQL and Elasticsearch. It provides a Python SDK for interacting with your database, and a UI for managing your data. With the XataChatMessageHistory class, you can use Xata databases for longer-term persistence of chat sessions.
This notebook covers:
A simple example showing what XataChatMessageHistory does.
A more complex example using a REACT agent that answer questions based on a knowledge based or documentation (stored in Xata as a vector store) and also having a long-term searchable history of its past messages (stored in Xata as a memory store)
Setup
Create a database
In the Xata UI create a new database. You can name it whatever you want, in this notepad we'll use langchain. The Langchain integration can auto-create the table used for storying the memory, and this is what we'll use in this example. If you want to pre-create the table, ensure it has the right schema and set create_table to False when creating the class. Pre-creating the table saves one round-trip to the database during each session initialization.
Let's first install our dependencies:
pip install xata openai langchain
Next, we need to get the environment variables for Xata. You can create a new API key by visiting your account settings. To find the database URL, go to the Settings page of the database that you have created. The database URL should look something like this: https://demo-uni3q8.eu-west-1.xata.sh/db/langchain.
import getpass
api_key = getpass.getpass("Xata API key: ")
db_url = input("Xata database URL (copy it from your DB settings):")
Create a simple memory store
To test the memory store functionality in isolation, let's use the following code snippet:
from langchain.memory import XataChatMessageHistory
history = XataChatMessageHistory(
session_id="session-1",
api_key=api_key,
db_url=db_url,
table_name="memory"
)
history.add_user_message("hi!") | https://python.langchain.com/docs/integrations/memory/xata_chat_message_history |
1e37ecfc94d3-1 | history.add_user_message("hi!")
history.add_ai_message("whats up?")
The above code creates a session with the ID session-1 and stores two messages in it. After running the above, if you visit the Xata UI, you should see a table named memory and the two messages added to it.
You can retrieve the message history for a particular session with the following code:
Conversational Q&A chain on your data with memory
Let's now see a more complex example in which we combine OpenAI, the Xata Vector Store integration, and the Xata memory store integration to create a Q&A chat bot on your data, with follow-up questions and history.
We're going to need to access the OpenAI API, so let's configure the API key:
import os
os.environ["OPENAI_API_KEY"] = getpass.getpass("OpenAI API Key:")
To store the documents that the chatbot will search for answers, add a table named docs to your langchain database using the Xata UI, and add the following columns:
content of type "Text". This is used to store the Document.pageContent values.
embedding of type "Vector". Use the dimension used by the model you plan to use. In this notebook we use OpenAI embeddings, which have 1536 dimensions.
Let's create the vector store and add some sample docs to it:
from langchain.embeddings.openai import OpenAIEmbeddings
from langchain.vectorstores.xata import XataVectorStore
embeddings = OpenAIEmbeddings()
texts = [
"Xata is a Serverless Data platform based on PostgreSQL",
"Xata offers a built-in vector type that can be used to store and query vectors",
"Xata includes similarity search"
]
vector_store = XataVectorStore.from_texts(texts, embeddings, api_key=api_key, db_url=db_url, table_name="docs")
After running the above command, if you go to the Xata UI, you should see the documents loaded together with their embeddings in the docs table.
Let's now create a ConversationBufferMemory to store the chat messages from both the user and the AI.
from langchain.memory import ConversationBufferMemory
from uuid import uuid4 | https://python.langchain.com/docs/integrations/memory/xata_chat_message_history |
1e37ecfc94d3-2 | chat_memory = XataChatMessageHistory(
session_id=str(uuid4()), # needs to be unique per user session
api_key=api_key,
db_url=db_url,
table_name="memory"
)
memory = ConversationBufferMemory(memory_key="chat_history", chat_memory=chat_memory, return_messages=True)
Now it's time to create an Agent to use both the vector store and the chat memory together.
from langchain.agents import initialize_agent, AgentType
from langchain.agents.agent_toolkits import create_retriever_tool
from langchain.chat_models import ChatOpenAI
tool = create_retriever_tool(
vector_store.as_retriever(),
"search_docs",
"Searches and returns documents from the Xata manual. Useful when you need to answer questions about Xata."
)
tools = [tool]
llm = ChatOpenAI(temperature=0)
agent = initialize_agent(
tools,
llm,
agent=AgentType.CHAT_CONVERSATIONAL_REACT_DESCRIPTION,
verbose=True,
memory=memory)
To test, let's tell the agent our name:
agent.run(input="My name is bob")
Now, let's now ask the agent some questions about Xata:
agent.run(input="What is xata?")
Notice that it answers based on the data stored in the document store. And now, let's ask a follow up question:
agent.run(input="Does it support similarity search?")
And now let's test its memory:
agent.run(input="Did I tell you my name? What is it?") | https://python.langchain.com/docs/integrations/memory/xata_chat_message_history |
39bf59e861b9-0 | Xorbits Inference (Xinference)
Xinference is a powerful and versatile library designed to serve LLMs, speech recognition models, and multimodal models, even on your laptop. It supports a variety of models compatible with GGML, such as chatglm, baichuan, whisper, vicuna, orca, and many others. This notebook demonstrates how to use Xinference with LangChain.
Installation
Install Xinference through PyPI:
%pip install "xinference[all]"
Deploy Xinference Locally or in a Distributed Cluster.
For local deployment, run xinference.
To deploy Xinference in a cluster, first start an Xinference supervisor using the xinference-supervisor. You can also use the option -p to specify the port and -H to specify the host. The default port is 9997.
Then, start the Xinference workers using xinference-worker on each server you want to run them on.
You can consult the README file from Xinference for more information.
Wrapper
To use Xinference with LangChain, you need to first launch a model. You can use command line interface (CLI) to do so:
xinference launch -n vicuna-v1.3 -f ggmlv3 -q q4_0
Model uid: 7167b2b0-2a04-11ee-83f0-d29396a3f064
A model UID is returned for you to use. Now you can use Xinference with LangChain:
from langchain.llms import Xinference
llm = Xinference(
server_url="http://0.0.0.0:9997",
model_uid = "7167b2b0-2a04-11ee-83f0-d29396a3f064"
)
llm(
prompt="Q: where can we visit in the capital of France? A:",
generate_config={"max_tokens": 1024, "stream": True},
)
' You can visit the Eiffel Tower, Notre-Dame Cathedral, the Louvre Museum, and many other historical sites in Paris, the capital of France.'
Integrate with a LLMChain
from langchain import PromptTemplate, LLMChain
template = "Where can we visit in the capital of {country}?"
prompt = PromptTemplate(template=template, input_variables=["country"]) | https://python.langchain.com/docs/integrations/llms/xinference |
39bf59e861b9-1 | prompt = PromptTemplate(template=template, input_variables=["country"])
llm_chain = LLMChain(prompt=prompt, llm=llm)
generated = llm_chain.run(country="France")
print(generated)
A: You can visit many places in Paris, such as the Eiffel Tower, the Louvre Museum, Notre-Dame Cathedral, the Champs-Elysées, Montmartre, Sacré-Cœur, and the Palace of Versailles.
Lastly, terminate the model when you do not need to use it:
xinference terminate --model-uid "7167b2b0-2a04-11ee-83f0-d29396a3f064" | https://python.langchain.com/docs/integrations/llms/xinference |

980fdf1a8fbc-0 | Runhouse
The Runhouse allows remote compute and data across environments and users. See the Runhouse docs.
This example goes over how to use LangChain and Runhouse to interact with models hosted on your own GPU, or on-demand GPUs on AWS, GCP, AWS, or Lambda.
Note: Code uses SelfHosted name instead of the Runhouse.
