Hello!I tried to setup a simple cogex extractor, but get an error that is not letting me proceed following the course. Please help.SyntaxWarning: invalid escape sequence '\e' """csv_extractor_2/__main__.py:13: error: Argument "run_handle" to "Extractor" hasincompatible type"Callable[[CogniteClient, AbstractStateStore, Config, Event], None]"; expected"Callable[[CogniteClient, AbstractStateStore, Config, CancellationToken], None] | None" [arg-type] run_handle=run_extractor, ^~~~~~~~~~~~~Found 1 error in 1 file (checked 4 source files) 

I'm experiencing significant delays while using the menu bar on Cognite Notebooks. Specifically, when I try to reopen menus like "File," "Edit," and "View," they take an unusually long time to respond. Additionally, I have a folder named "Notebooks" with several subfolders, and it takes a long time for all the subfolders to display when I try to access them.Has anyone else encountered similar issues? Is there any way to solve these problems?Thanks!

Display events in Cognite Charts which does not have End time.Presently Events does not have End time will not display in Cognite Charts if user try to customize Timeseries for specific duration.Not showing the failures linked to the asset in Charts CDF view, not consistent with the linked failures in Data Explorer. Login to CDF UI Navigate to Data Explorer screen. Click on the Charts tab in menu bar Click on New Chart button.

Hi All.I want to deploy multiple PI Extractors on a VM with different configurations and the possibility to start and stop them separately. How can I achieve that? Or do I need to have multiple VMs? Thanks a lot in advance!

How can you with the opc-ua extractor read from the server only some specific tags with some parameter in the YML configuration file?So far with this extractor all tags are sent to CDF.

On behalf of Celanese, I’d like to understand if adding more than one Security Category to a single file or timeseries is supported by the CDF platform and APIs. Also, can it be confirmed that if a certain file is under two categories, only users that are capable of seeing both categories will be able to see it? Thanks!

Is there a way to query metadata of TimeSeries from a particular dataset in CDF Transformations?Something like this, but this query isn’t workingselect  cast(`externalId` as STRING) as externalId,  cast(`dataSetId` as STRING) as eidfrom  `_cdf`.`timeseries`where dataSetId == <data_set_id>;

HiFor a use case I am working on I need to retrieve information about the raw tables in our environment. What I need to do is that i need to retrieve the name of each of the  columns and the datatypes of the columns for every single raw table we have in our environment. I have looked through the python SDK docs, but have not been able to find out how to do this. I noticed that it is possible to do a preview of a transformation through the SDK and get a schema out this way, however this feels a bit too “hacky” and is also very time consuming and inefficient. Does anyone have any idea of how I can get what I need?ThanksSebastian

Here are some issues we are facing with TimeSeriesUploadQueue after migrating to lastest version :Unable to upload rows, though it says it has been uploaded in latest versionIt says uploader uploaded x datapoints even though it doesnt (checked in ui and through api) , and uploaded rows is None even though there are datapoints to upload. Same code works fine in version 6.This is our post upload function: Wrong date range is uploaded in version 7.  (happens on a random basis)The target timeseries didnt exist before we run the extractor. The date range we were trying to upload in the first batch is October 25

Hi all,I'm trying to increment my view version.To do this, I'm also incrementing my data model version as well.My original is```type Test @view(space: "test_space", version: "1_0"){    name: String!,    description: String,}```and I try to go to```type Test @view(space: "test_space", version: "1_1"){    name: String!,    description: String,    test_write: String}```I've also tried ```type Test @view(space: "test_space", version: "1_2"){    name: String!,    description: String,    test_write: String,    required_test_write: String!}```I get this error: {  "title": "Error: could not update data model",  "message": "An error has occured.

Hey everyone ! Welcome back to our data modeling adventure in CDF! In my first post, I tried to explain my understanding of the core concepts - spaces, containers, views, and the elusive knowledge graph. We learned how data models act as the foundation for unlocking the power of Cognite Data Fusion for your industrial data.This time, let's delve deeper into the world of views and containers - the essential ingredients that bring your data models to life! Beyond the Fundamentals: Unveiling Views and ContainersThink of a data model as a recipe. It doesn't contain the actual ingredients (data) itself, but it tells yo

I am facing this error in the data science course on “creating cognite functions” with cognite SDK. In previous courses I had fixed this error by replacing the “datapoints” keyword with “time_series”. However, I would like to know if I am probably not using the write packages; OR not know if the commands are deprecated and have new function names in newer versions. Kindly let me know - I am trying to finish these courses before my local boot camp next week.Thanks,Lavanya

Hello,I’m encountering an issue with accessing a dataset on Cognite Jupyter Notebooks. According to this link: Jupyter Notebook in Cognite Data Fusion | Cognite Documentation, subfolders will appear empty if I don’t have access to the dataset. However, I can see the dataset through the data model corresponding to that dataset, but I still can't see any contents inside the subfolders.Do I need anotther type of access or is it another issue? Any help would be much appreciated.Thanks!

Hey guys. I’m trying to create a function with some different constants. Do you know how can I change the name of the constants? 

Hi,I have some questions on Cognite. Would you please help?1. Files1.1 To delete Cognite files, after deleting the files do we need to delete the documents also? 1.2 After we create the files, the documents are created by Cognite automatically, but it seems there are some random delay to create the document, why?1.3 what is the concept of document in Cognite? Why is it created? Any documents on that?2. sequences2.1 To delete Cognite sequences, after deleting the sequences do we need to delete the datapoints also? 3. timeseries3.1 To delete Cognite timeseries, after deleting the timeseries do we need to delete the datapoints also?4. delete order for containers, views 4.1 to delete all FDM data in a space, the order of deletion should be edges, nodes, containers, view versions, data models, space. And the containers should be deleted first then delete the view versions, right?Thank you!Alice

I’m working on a prototype for a flexible data model to store time series data in a way that is easy to catalogue, query and filter. Using Pygen both to populate and use the model seems convenient.At its current iteration, I’ve only applied direct relations and (undocumented?) @reverseDirectRelations in the GraphQL schema. I expected to be able do something similar to client.windmill(windfarm="Hornsea 1").blades(limit=-1).sensor_positions(limit=-1).query()as found in the Pygen documentation, but it does not work (my client.windmill analouge has no methods corresponding to its relations). Do I have to use edges instead of relations to query easily and declaratively with Pygen?

This document outlines a concept that CDF has been under development for the last 2 years. As mentioned during the disclaimer above, please use this Cognite Hub group and share any feedback you have around flexible data modeling.This document is reflecting some very early thinking from the App Dev Journey team, and is a mental model that will likely change overtime with your feedback!What is a Data Model​A data model enables users to customize the shape, structure their expectation of data. It plays a crucial part in building solutions (like data science models, mobile and web apps). But it is also is the core of an ontology, knowledge graphs, or industry standard.

Dear community,We have been working with Python SDK developing functions and everything works fine, as expected.Now we have an IP development that has C# as base language. We need to call some of the Cognite Functions utilizing the .net SDK (https://github.com/cognitedata/cognite-sdk-dotnet)  but we are having troubles to call the functions trough .net.Has anyone been able to utilize Cognite Functions trough the .net SDK?Thank you all.Here is a snippet of the code: 

I am trying to create a Data Model in the UI. I can click ‘create data model’, name it, and land on the page with the editor and the pre commented pump/facility/documenation example. However I am not able to edit the graphql as anytime I try to edit in the editor I am told that I ‘cannot edit in read-only editor. Where is the toggle to disable the read-only editor?

After how much time retry of function get triggered on failing?Is there a way we can set the time to retrigger the function after function fails. It will be helpful to deal with rate limit in functions if any.

Hello, how can I delete all the time series of a dataset with python sdk?
