+# MyScale
+
+This page covers how to use MyScale vector database within LangChain.
+It is broken into two parts: installation and setup, and then references to specific MyScale wrappers.
+
+With MyScale, you can manage both structured and unstructured (vectorized) data, and perform joint queries and analytics on both types of data using SQL. Plus, MyScale's cloud-native OLAP architecture, built on top of ClickHouse, enables lightning-fast data processing even on massive datasets.
+
+## Introduction
+
+[Overview to MyScale and High performance vector search](https://docs.myscale.com/en/overview/)
+
+You can now register on our SaaS and [start a cluster now!](https://docs.myscale.com/en/quickstart/)
+
+If you are also interested in how we managed to integrate SQL and vector, please refer to [this document](https://docs.myscale.com/en/vector-reference/) for further syntax reference.
+
+We also deliver with live demo on huggingface! Please checkout our [huggingface space](https://huggingface.co/myscale)! They search millions of vector within a blink!
+
+## Installation and Setup
+- Install the Python SDK with `pip install clickhouse-connect`
+
+### Setting up envrionments
+
+There are two ways to set up parameters for myscale index.
+
+1. Environment Variables
+
+    Before you run the app, please set the environment variable with `export`:
+    `export MYSCALE_URL='<your-endpoints-url>' MYSCALE_PORT=<your-endpoints-port> MYSCALE_USERNAME=<your-username> MYSCALE_PASSWORD=<your-password> ...`
+
+    You can easily find your account, password and other info on our SaaS. For details please refer to [this document](https://docs.myscale.com/en/cluster-management/)
+    Every attributes under `MyScaleSettings` can be set with prefix `MYSCALE_` and is case insensitive.
+
+2. Create `MyScaleSettings` object with parameters
+
+
+    ```python
+    from langchain.vectorstores import MyScale, MyScaleSettings
+    config = MyScaleSetting(host="<your-backend-url>", port=8443, ...)
+    index = MyScale(embedding_function, config)
+    index.add_documents(...)
+    ```
+  
+## Wrappers
+supported functions:
+- `add_texts`
+- `add_documents`
+- `from_texts`
+- `from_documents`
+- `similarity_search`

+whether for semantic search or similar example retrieval.
+
+To import this vectorstore:

+# Prediction Guard
+
+This page covers how to use the Prediction Guard ecosystem within LangChain.
+It is broken into two parts: installation and setup, and then references to specific Prediction Guard wrappers.
+
+## Installation and Setup
+- Install the Python SDK with `pip install predictionguard`
+- Get an Prediction Guard access token (as described [here](https://docs.predictionguard.com/)) and set it as an environment variable (`PREDICTIONGUARD_TOKEN`)
+
+## LLM Wrapper
+
+There exists a Prediction Guard LLM wrapper, which you can access with 
+```python
+from langchain.llms import PredictionGuard
+```
+
+You can provide the name of your Prediction Guard "proxy" as an argument when initializing the LLM:
+```python
+pgllm = PredictionGuard(name="your-text-gen-proxy")
+```
+
+Alternatively, you can use Prediction Guard's default proxy for SOTA LLMs:
+```python
+pgllm = PredictionGuard(name="default-text-gen")
+```
+
+You can also provide your access token directly as an argument:
+```python
+pgllm = PredictionGuard(name="default-text-gen", token="<your access token>")
+```
+
+## Example usage
+
+Basic usage of the LLM wrapper:
+```python
+from langchain.llms import PredictionGuard
+
+pgllm = PredictionGuard(name="default-text-gen")
+pgllm("Tell me a joke")
+```
+
+Basic LLM Chaining with the Prediction Guard wrapper:
+```python
+from langchain import PromptTemplate, LLMChain
+from langchain.llms import PredictionGuard
+
+template = """Question: {question}
+
+Answer: Let's think step by step."""
+prompt = PromptTemplate(template=template, input_variables=["question"])
+llm_chain = LLMChain(prompt=prompt, llm=PredictionGuard(name="default-text-gen"), verbose=True)
+
+question = "What NFL team won the Super Bowl in the year Justin Beiber was born?"
+
+llm_chain.predict(question=question)
+```

I also heard that at first it was seized by U.S. customs if it ever tried to enter this country, therefore being a fan of films considered \"controversial\" I really had to see this for myself.<br /><br />The plot is centered around a young Swedish drama student named Lena who wants to learn everything she can about life. In particular she wants to focus her attentions to making some sort of documentary on what the average Swede thought about certain political issues such as the Vietnam War and race issues in the United States. In between asking politicians and ordinary denizens of Stockholm about their opinions on politics, she has sex with her drama teacher, classmates, and married men.<br /><br />What kills me about I AM CURIOUS-YELLOW is that 40 years ago, this was considered pornographic. Really, the sex and nudity scenes are few and far between, even then it\\'s not shot like some cheaply made porno. While my countrymen mind find it shocking, in reality sex and nudity are a major staple in Swedish cinema. Even Ingmar Bergman, arguably their answer to good old boy John Ford, had sex scenes in his films.<br /><br />I do commend the filmmakers for the fact that any sex shown in the film is shown for artistic purposes rather than just to shock people and make money to be shown in pornographic theaters in America.

I\\'ve seen R-rated films with male nudity. Granted, they only offer some fleeting views, but where are the R-rated films with gaping vulvas and flapping labia? Nowhere, because they don\\'t exist. The same goes for those crappy cable shows: schlongs swinging in the breeze but not a clitoris in sight. And those pretentious indie movies like The Brown Bunny, in which we\\'re treated to the site of Vincent Gallo\\'s throbbing johnson, but not a trace of pink visible on Chloe Sevigny. Before crying (or implying) \"double-standard\" in matters of nudity, the mentally obtuse should take into account one unavoidably obvious anatomical difference between men and women: there are no genitals on display when actresses appears nude, and the same cannot be said for a man. In fact, you generally won\\'t see female genitals in an American film in anything short of porn or explicit erotica.

In all, I believe that Lucille Ball is one of those inimitable people who simply cannot be portrayed by anyone other than themselves.

To think about a legend like Lucille Ball being portrayed the way she was in the movie is horrendous. I cannot believe out of all the actresses in the world who could play a much better Lucy, the producers decided to get Rachel York. She might be a good actress in other roles but to play the role of Lucille Ball is tough. It is pretty hard to find someone who could resemble Lucille Ball, but they could at least find someone a bit similar in looks and talent. If you noticed York\\'s portrayal of Lucy in episodes of I Love Lucy like the chocolate factory or vitavetavegamin, nothing is similar in any way-her expression, voice, or movement.<br /><br />To top it all off, Danny Pino playing Desi Arnaz is horrible. Pino does not qualify to play as Ricky. He\\'s small and skinny, his accent is unreal, and once again, his acting is unbelievable. Although Fred and Ethel were not similar either, they were not as bad as the characters of Lucy and Ricky.<br /><br />Overall, extremely horrible casting and the story is badly told. If people want to understand the real life situation of Lucille Ball, I suggest watching A&E Biography of Lucy and Desi, read the book from Lucille Ball herself, or PBS\\' American Masters: Finding Lucy. If you want to see a docudrama, \"Before the Laughter\" would be a better choice. The casting of Lucille Ball and Desi Arnaz in \"Before the Laughter\" is much better compared to this.

Ben Gazzara sports his usual cat\\'s-got-canary grin in a futile attempt to elevate the meager plot, which requires him to pursue Audrey Hepburn with all the interest of a narcoleptic at an insomnia clinic. In the meantime, the budding couple\\'s respective children (nepotism alert: Bogdanovich\\'s daughters) spew cute and pick up some fairly disturbing pointers on \\'love\\' while observing their parents.

It\\'s a movie and we can expect that much, if that\\'s what you\\'re looking for you\\'d be better off picking up a copy of Vogue.<br /><br />Oh- and it has to be mentioned that Colleen Camp thoroughly annoys, even apart from her singing, which, while competent, is wholly unconvincing... the country and western numbers are woefully mismatched with the standards on the soundtrack. Surely this is NOT what Gershwin (who wrote the song from which the movie\\'s title is derived) had in mind; his stage musicals of the 20\\'s may have been slight, but at least they were long on charm. \"They All Laughed\" tries to coast on its good intentions, but nobody- least of all Peter Bogdanovich - has the good sense to put on the brakes.<br /><br />Due in no small part to the tragic death of Dorothy Stratten, 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.

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.

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.

+If you do not wish to specify `input_variables` manually, you can also create a `PromptTemplate` using `from_template` class method. `langchain` will automatically infer the `input_variables` based on the `template` passed.
+
+```python
+template = "Tell me a {adjective} joke about {content}."
+
+prompt_template = PromptTemplate.from_template(template)
+prompt_template.input_variables
+# -> ['adjective', 'content']
+prompt_template.format(adjective="funny", content="chickens")
+# -> Tell me a funny joke about chickens.
+```
 
 You can create custom prompt templates that format the prompt in any way you want. For more information, see [Custom Prompt Templates](examples/custom_prompt_template.ipynb).
 
 
 <!-- TODO(shreya): Add link to Jinja -->
 
-:::{note}
-Currently, the template should be formatted as a Python f-string. We also support Jinja2 templates (see [Using Jinja templates](examples/custom_prompt_template.ipynb)). In the future, we will support more templating languages such as Mako.

-## Load a prompt template from LangChainHub
-
-LangChainHub contains a collection of prompts which can be loaded directly via LangChain.
+## Template formats
 
+By default, `PromptTemplate` will treat the provided template as a Python f-string. You can specify other template format through `template_format` argument:
 
 ```python
+# Make sure jinja2 is installed before running this
+
+jinja2_template = "Tell me a {{ adjective }} joke about {{ content }}"
+prompt_template = PromptTemplate.from_template(template=jinja2_template, template_format="jinja2")
+
+prompt_template.format(adjective="funny", content="chickens")
+# -> Tell me a funny joke about chickens.
+```
+
+Currently, `PromptTemplate` only supports `jinja2` and `f-string` templating format. If there is any other templating format that you would like to use, feel free to open an issue in the [Github](https://github.com/hwchase17/langchain/issues) page. 
+
+## Validate template
+
+By default, `PromptTemplate` will validate the `template` string by checking whether the `input_variables` match the variables defined in `template`. You can disable this behavior by setting `validate_template` to `False`
+
+```python
+template = "I am learning langchain because {reason}."
+
+prompt_template = PromptTemplate(template=template, 
+                                 input_variables=["reason", "foo"]) # ValueError due to extra variables
+prompt_template = PromptTemplate(template=template, 
+                                 input_variables=["reason", "foo"], 
+                                 validate_template=False) # No error
+```
+
+
+## Serialize prompt template
+
+You can save your `PromptTemplate` into a file in your local filesystem. `langchain` will automatically infer the file format through the file extension name. Currently, `langchain` supports saving template to YAML and JSON file. 
+
+```python
+prompt_template.save("awesome_prompt.json") # Save to JSON file
+```
+
+```python
+from langchain.prompts import load_prompt
+loaded_prompt = load_prompt("awesome_prompt.json")
+
+assert prompt_template == loaded_prompt
+```
+
+`langchain` also supports loading prompt template from LangChainHub, which contains a collection of useful prompts you can use in your project. You can read more about LangChainHub and the prompts available with it [here](https://github.com/hwchase17/langchain-hub).
+
+```python
+
 from langchain.prompts import load_prompt
 
 prompt = load_prompt("lc://prompts/conversation/prompt.json")
 prompt.format(history="", input="What is 1 + 1?")
 ```
