Where is the "Write Weights" ans "Read Weights" operators?

yasinkayayasinkaya Member Posts: 10 Contributor II
How do I write to the file the features (weights output) I get in the feature selection operator.
Older versions of the RM had "write weights" and "read weights" operators for this purpose. But now, in the newest version they are depreciated.

    Hi,
    we recommend to use Weights to Data first and then use the normal Write-CSV or Write-Excel if you need it readable. Otherwise you can use Store to write it into the repository.

    Thank you Mr. @mschmitz.

    Then how do I do the opposite of that?

    I can't get true features saved to CSV file when I try to filter data using "read csv" and "data to weights". (Edit: Corrected this sentence, I didn't get an error message)

    How to perform the function "read weights".

    Hello @yasinkaya

    Looks like your process flow is fine. Can you inform the error details?

    There is no error. Sorry. But it don't give expected output from the weights port. I'll add a picture. 

  • yasinkayayasinkaya Member Posts: 10 Contributor II
    It is not select features using saved features to CSV file. 
    Why Write Weights and Read Weights deprecated?

    If there is no operator with the same convenience instead, why did these operators removed?
