I got this error when I use LoadData module, can anyone help me with why this error occurs?
this is my csv file:
load2.csv (542 Bytes)

Hi tahi,
I’m currently encountering the same error trying to build an illumination pipeline with the LoadData module.

Have you managed to work that out ?
Thanks for attaching that csv file. I’ve replicated your issue and I believe this is coming from the first column of your spreadsheet, which has no column name. If you delete that column, I no longer get the error. If you’re using pandas to create this file, usually this happens because you haven’t turned off the option to save out the row index or row number when saving the csv.
