Hello All,

I was going through the training yesterday and got all the way to the end of Working with CDF: Contextualize and the system got stuck trying to create the interactive PID. Fast forward to this morning and I re-did creating the interactive engineering diagram and it worked.

I then moved on to the next course Working with CDF: Consume and while I was trying to find my timeseries I noticed that my Kyle1995-IFSDB data catalog no longer had any time series associated with it (see below). I then tried to do the data transform for the timeseries data and it tells me that it has updated 12 timeseries but I still cannot find those timeseries in my data catalog anywhere(see below).

I should also note that I did do the optional contextualization exercise of linking the timeseries to assets. I then also ran the contextualization using the entity matchers.

What can I do to get my timeseries data back so that I can continue on with the training?

 

 

The only was able to get the timeseries to show in my data catalog again was to delete the FirstnameBirthyear-Timeseries Data Transformation and re-do it.

 

I also found a bug in the Contextualize > Match resources to assets > Quick Match page where it doesn’t show the entities that have been found (see below in red) despite there being results (see below in cyan).

 

This issue also seems to result in not being able to create additional fields when configuring the model, I guess due to the fact that the system doesn’t seem to think that anything was found in the timeseries step (see below in red).

That being said it still appears to run based on what is actually in the system and not what the GUI is showing.

Calculate Delta T :

Click + Add Note, go to Source, and select both of the time series. 

The above lines should be : 

Click + Add Node, go to Source, and select both of the time series.

Please correct the training material.

 

Thanks

Hi @DE KOCK Kyle ! Thanks for your feedback! When I try to take a look at the data, I find your data sets as archived. Did you do this after you tried the matching? Some of the search fields filter away archived data sets. 


I see that you have the assets, time series and events data. Your time series data is also contextualized to the relating assets. Did you manage with the Match resources? Or is this contextualization from using transformations?

Hi @Sofie Haug,

I archived all of my data as I was able to complete the course and do the test after I deleted and recreated my timeseries as mentioned at the beginning of my post. Once that was complete I was able to perform the contextualization with Quick Match but as I show in my post there were some problems with the GUI not showing the entities that match the search parameters of the quick match (this was while my data was not archived). Interestingly enough this was only the case with the 12 timeseries and not the 36 assets.

Another thing I should also mention is that, I was unable to find any data in the graphs after I recreated the Timeseries transformation regardless of the time range (I know the course mentions November 2020 - 2021). This was also while my data was not archived.

Hi again @DE KOCK Kyle 

 

Thank for your reply! 
Good to hear that you finished! I will give the feedback to the teams responsible for the tools you mention!

Thank you!

I’m having issue following the “Contextualize using entity matcher” lesson within the “Working With CDF: Contextualize”. My datasets aren’t appearing.

I tried to restart and refresh.

I’ve closed and reopened.

For some reason, I can find my dataset in any of the tools I’ve used (Explore, Transform, Create, etc.) EXCEPT entity matching…

Can someone help?

Hi again @Mahmoud Shihab, 

I am not able to see your transformations nor your datasets. Can you please check from your end if you can see them, and provide a screenshot if possible?

Thank you!

Hi Madina,

I’m a little embarrassed to say this, but I ended up using the SQL entity matching for the course in order to continue to the assessment. But as I was wrapping up the course, I got to the clean up stage, and forgot that I had posted this issue. 

My apologies.

I can try it once more and provide a screenshot of the issue I am receiving.

Should just take a moment

Hi Madina,

I think there might have been something with the first Data Set, because this one can be found.

I’m not sure what the initial issue was, but I guess a tip to anyone is if your dataset isn’t found the first time, try recreating it. That’s what worked for me.

Thanks again for your assistance Madina.

Hello,

 

I am facing a issue with Entity Matcher module, I have my datasets created but not able to search them in the screenshot below. I was able to see one of them, I refreshed to see another but then both of them disappeared .

Hi Deepali,

I had the same issue as well! I’m not sure why, but it just eventually worked when I recreated my datasets again from scratch. At the time, I ended up deleting everything and rebuilding it all from scratch, but it eventually worked for me.

I know it’s not the best answer, but try rebuilding/creating new datasets…

Hopefully Madina might be able to tackle the issue when she can.

Note: Don’t delete the ones you’ve made now so Madina can see why it’s not working as expecgted

Hi Rahul,

 

Thanks for the response.  I am able to access the data files in manage data catalog with no issue.  I am logged in to the cdf-fundamentals project as well.  My data sets are named Bernard1977 as seen below:

When navigating to the charts section, I am having issues.  Please see screenshots below. 

First it shows as if its trying to load like this:

 

And I ultimately receive this after trying to reload;

Any help will be greatly appreciated.  This is the final module prior to certification.

Thanks

Hi @Deepali Gupta, @Mahmoud Shihab,

This is not a bug. Unless you have a related resource type(timeseries, sequence, files, events) tagged to a data set it wont be displayed in this particular screen. If you are tying to select a file then the particular file should have the data set mapped.

I hope that helps.

Jude

Hi Bbauri,

Thanks for providing the console snap short of browser.
I have investigate deeply and found out all is working fine with the fusion. In the console , you have problem with failed to load resource:net::ERR_CERT_AUTHORITY_INVALID, which is related to your network connection and SSL certificate.

I recommend you to check your network connection and SSL certificate in your browser.

Good morning everyone, 

 

I am not sure if this it the right place to ask this, but I am currently unable to download the “CHANGE_NAME.pdf” file in the “Working With CDF: Contextualize” section of “Cognite Data Fusion Fundamentals” course. Has anybody experience the same issue before? I am getting an “access denied” error :(

 

Please let me know if can get any help here! :)
