Prediction new data using regression after export

Hi,

Dear all;

I have trained IV curve dataset for photo voltaic system with guassian regression model with RMSE=0.002. After exporting compact Model, i am getting the following error. I also used load table command to load test data to be predicted. How can i remove this error. I will be very thankful for your kind guidance.

>> T=readtable("Test2.xlsx");

>> yfit = trainedModel.predictFcn(T)
