How to train a CNN for two or three inputs

Morning Everyone,

Iam actually facing one issue for the training of the CNN model with two inputs for image classification. When i load the model i get this error message.

Error using trainNetwork

Invalid training data. For a network with 2 inputs and 1 output, the datastore read function must return a cell array with 3 columns, but

it returns a cell array with 2 columns.

Hi @JOEL PATERNE KOUAME

For a network with multiple inputs, MATLAB expects the training data to be organized in a specific way. The first two columns should contain the data for the two inputs, and the third column should contain the corresponding output (label).

You can refer to this MATLAB answer for more clarity.

Hope this helps!
