I made a table for neural network regression,
regNet = trainNetwork(trData,'Percent',layers,options), and gor the following error
Error using trainNetwork (line 165)
Invalid training data table for regression. Predictors must be in the first column of the table, as a cell array of image paths or images.
The Table, .txt file, I made has two variables, a string and a double, The first two rows looks like this. I thought they look exactly as in the tutorial .
