Hi Everyone,
I have recently started using Knime Analytics. I am trying to implement Time series forecasting.
While using the Linear Regression Learner, I am facing this error saying, “No column in spec compatible to Double value” due to which I am not able to open the blockset.
Can anyone help me to get through? I do not understand what it is trying to say.
The dataset I am using is all numerical data, no strings.
Thanks in advance.
Hello @piyushmodi1987,
and welcome to KNIME Community!
Although you have numerical columns in your data they are probably read as string columns in KNIME and thus you can not open configuration. How did you read your data into KNIME?
Column types can be checked if you open table output and next to column name you’ll find column type sign or from table view go to Spec tab.
Br,
Ivan
