I'm trying to select some columns from a dataset in Microsoft Azure ML Studio. My dataset column is a decimal at first. enter image description here After I pass the data through a "Select Column in Dataset" asset, the same column becomes a string, instead of remaining decimal. enter image description here

Any idea why this is happening?

Not able to find exact reason for why decimal datatype is changing to string data type after Select Columns.

As per this answer by akashperfect to similar type of question, Check if there are any NULL values. There couldn't be NULL values in your column. First clear the missing data and perform edit metadata step.

  • I was able to do the trick with 1. CLEAN MISSING DATA (on only columns I wanted then REMOVE ENTIRE ROW if missing) 2. EDIT MEDATADA (for my columns). – Andrei Iovan Jan 06 '22 at 13:46
