DAX queries have a simple syntax comprised of just one required keyword, EVALUATE, and several optional keywords: ORDER BY, START AT, DEFINE, MEASURE, VAR, TABLE, and COLUMN. Each keyword defines a statement used for the duration of the query. Any time < or > are used in the text below it means that those values need to be replaced by table, columns or other things. + +Some DAX functions return a table instead of a scalar, and must be wrapped in a function that evaluates the table and returns a scalar; unless the table is a single column, single row table, then it is treated as a scalar value. Most DAX functions require one or more arguments, which can include tables, columns, expressions, and values. However, some functions, such as PI, do not require any arguments, but always require parentheses to indicate the null argument. For example, you must always type PI(), not PI. You can also nest functions within other functions. + +Some commonly used functions are: +EVALUATE - At the most basic level, a DAX query is an EVALUATE statement containing a table expression. At least one EVALUATE statement is required, however, a query can contain any number of EVALUATE statements. +EVALUATE
ORDER BY ASC or DESC - The optional ORDER BY keyword defines one or more expressions used to sort query results. Any expression that can be evaluated for each row of the result is valid. +EVALUATE
ORDER BY ASC or DESC START AT or - The optional START AT keyword is used inside an ORDER BY clause. It defines the value at which the query results begin. +DEFINE MEASURE | VAR; EVALUATE
- The optional DEFINE keyword introduces one or more calculated entity definitions that exist only for the duration of the query. Definitions precede the EVALUATE statement and are valid for all EVALUATE statements in the query. Definitions can be variables, measures, tables1, and columns1. Definitions can reference other definitions that appear before or after the current definition. At least one definition is required if the DEFINE keyword is included in a query. +MEASURE
[] = - Introduces a measure definition in a DEFINE statement of a DAX query. +VAR = - Stores the result of an expression as a named variable, which can then be passed as an argument to other measure expressions. Once resultant values have been calculated for a variable expression, those values do not change, even if the variable is referenced in another expression. + +FILTER(
,) - Returns a table that represents a subset of another table or expression, where is a Boolean expression that is to be evaluated for each row of the table. For example, [Amount] > 0 or [Region] = "France" +ROW(, ) - Returns a table with a single row containing values that result from the expressions given to each column. +DISTINCT() - Returns a one-column table that contains the distinct values from the specified column. In other words, duplicate values are removed and only unique values are returned. This function cannot be used to Return values into a cell or column on a worksheet; rather, you nest the DISTINCT function within a formula, to get a list of distinct values that can be passed to another function and then counted, summed, or used for other operations. +DISTINCT(
) - Returns a table by removing duplicate rows from another table or expression. + +Aggregation functions, names with a A in it, handle booleans and empty strings in appropriate ways, while the same function without A only uses the numeric values in a column. Functions names with an X in it can include a expression as an argument, this will be evaluated for each row in the table and the result will be used in the regular function calculation, these are the functions: +COUNT(), COUNTA(), COUNTX(

(#3135) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Hi there！ I'm excited to open this PR to add support for using a fully Postgres syntax compatible database 'AnalyticDB' as a vector. As AnalyticDB has been proved can be used with AutoGPT, ChatGPT-Retrieve-Plugin, and LLama-Index, I think it is also good for you. AnalyticDB is a distributed Alibaba Cloud-Native vector database. It works better when data comes to large scale. The PR includes: - [x] A new memory: AnalyticDBVector - [x] A suite of integration tests verifies the AnalyticDB integration I have read your [contributing guidelines](https://github.com/hwchase17/langchain/blob/72b7d76d79b0e187426787616d96257b64292119/.github/CONTRIBUTING.md).

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.

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.

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.

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.

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.

Ritter dons glasses so as to hammer home his character\\'s status as a sort of doppleganger of the bespectacled Bogdanovich; the scenes with the breezy Ms. Stratten are sweet, but have an embarrassing, look-guys-I\\'m-dating-the-prom-queen feel to them. 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.

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.

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. 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.

This is a curio for people who want to see Dorothy Stratten, who was murdered right after filming.

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.

The `limit` was being used both as an overall page limit *and* as a per request pagination limit. This, in combination with the fact that atlassian seem to use a server-side hard limit of 100 when page content is expanded, meant it wasn't possible to download >100 pages. Now `limit` is used *only* as a per-request pagination limit and `max_pages` is introduced as the way to limit the total number of pages returned by the paginator. - Document metadata now includes `source` (the source url), making it compatible with `RetrievalQAWithSourcesChain`. - It is now possible to include inline and footer comments. - It is now possible to pass `verify_ssl=False` and other parameters to the confluence object for use cases that require it. --- langchain/document_loaders/confluence.py | 94 ++++++++++++++----- .../document_loaders/test_confluence.py | 17 +++- 2 files changed, 87 insertions(+), 24 deletions(-) diff --git a/langchain/document_loaders/confluence.py b/langchain/document_loaders/confluence.py index 56598e64a88..3ae97f937e0 100644 --- a/langchain/document_loaders/confluence.py +++ b/langchain/document_loaders/confluence.py @@ -60,6 +60,8 @@ class ConfluenceLoader(BaseLoader): :type min_retry_seconds: Optional[int], optional :param max_retry_seconds: defaults to 10 :type max_retry_seconds: Optional[int], optional + :param confluence_kwargs: additional kwargs to initialize confluence with + :type confluence_kwargs: dict, optional :raises ValueError: Errors while validating input :raises ImportError: Required dependencies not installed.

With this addition, users can authenticate to Weaviate and make requests to private Weaviate servers when using these methods. ## Motivation Currently, LangChain's VectorStore methods do not provide a way to authenticate to Weaviate. This limits the functionality of the library and makes it more difficult for users to take advantage of Weaviate's features. This PR addresses this issue by adding support for providing a Weaviate API Key as extra parameter used in the `from_texts` method. ## Contributing Guidelines I have read the [contributing guidelines](https://github.com/hwchase17/langchain/blob/72b7d76d79b0e187426787616d96257b64292119/.github/CONTRIBUTING.md) and the PR code passes the following tests: - [x] make format - [x] make lint - [x] make coverage - [x] make test --- langchain/vectorstores/weaviate.py | 42 +++++++++++++++++++++++------- 1 file changed, 32 insertions(+), 10 deletions(-) diff --git a/langchain/vectorstores/weaviate.py b/langchain/vectorstores/weaviate.py index dd5e79cac77..0ad33b1a525 100644 --- a/langchain/vectorstores/weaviate.py +++ b/langchain/vectorstores/weaviate.py @@ -25,6 +25,35 @@ def _default_schema(index_name: str) -> Dict: } +def _create_weaviate_client(**kwargs: Any) -> Any: + client = kwargs.get("client") + + if client is not None: + return client + + weaviate_url = get_from_dict_or_env(kwargs, "weaviate_url", "WEAVIATE_URL") + weaviate_api_key = get_from_dict_or_env( + kwargs, "weaviate_api_key", "WEAVIATE_API_KEY", None + ) + + try: + import weaviate + except ImportError: + raise ValueError( + "Could not import weaviate python package.

This is obviously less than ideal. (Yeah, I don't understand why "expose" is the syntax that does not expose the ports to the host...) Tested by running langchain-server and trying out debugging on a host that already has postgresql bound to the port 5432.

(#3563) Often an LLM will output a requests tool input argument surrounded by single quotes. This triggers an exception in the requests library.

This is because those models return an iterator. So, I've updated the Replicate `_call` code to join together the output. The other advantage of this fix is that if you requested multiple outputs you would get them all – previously I was just returning output[0]. I also adjusted the demo docs to use dolly, because we're featuring that model right now and it's always hot, so people won't have to wait for the model to boot up.
