Cognite Academy is excited to share with you the new Data Scientist Basics learning path!

When your data is contextualized in Cognite Data Fusion, it’s time to start building your solutions. This new learning path on Cognite Academy, our e-learning portal, teaches you how to access the data with the APIs and SDKs that Cognite provides, and how to use Cognite and third party tools to analyze and visualize your data. The learning path is aimed at data scientists. However, solution architects, data engineers, and domain engineers with some coding knowledge can also find it useful and relevant.
 

By the end of the learning path, you will be able to:

  • Access the data using Cognite Python SDK. 

  • Build solutions to industrial use cases on Cognite Charts. 

  • Use Cognite Functions to deploy and schedule your Python function.

  • Connect Grafana and Power BI to a CDF project.

Upon successful completion, you’ll earn a certificate and gain the Data Scientist badge here on Cognite Hub.

Register for the learning path.

    Here is the error log:

    • The function terminated unexpectedly. Please contact Cognite support if the problem persists.
    • _point.py", line 455, in run_handle
    • result = handle(*function_argument_values)
    • File "/home/site/wwwroot/function/handler.py", line 41, in handle
    • df = client.datapoints.retrieve_dataframe(
    • AttributeError: 'CogniteClient' object has no attribute 'datapoints'
    • 2023-04-27 10:43 Function ended

    @Asan Arifov it seems that you use the latest version of cognite-sdk, and there you can retrieve datapoints like that: 

    >>> from cognite.client import CogniteClient

    >>> client = CogniteClient()

    >>> dps = client.time_series.data.retrieve(id=42, start="2w-ago")

     

    To resolve the issue you can either update the code or use the 5th version of SDK.

      Hi @roman.chesnokov, thanks..

      So Cognite SDK versions are not backward compatible? Is it possible to specify what SDK version server have to use in cognite function requirements.txt?

      @Asan Arifov the major versions don't guarantee backward compatibility. Recently SDK was updated to version 6. But of course you can specify the version in requirements.
