What are the values of the variables, imgdtsTrain and imgdtsValidation ?

在 MATLAB Online 中打开

[imgdtsTrain,imgdtsValidation] = splitEachLabel(imgdts,...
    trainingNumFiles,'randomize') % 'imgdts' is my image data source

You've defined a variable named trainingOptions. That line of code is being interpreted as an attempt to index into that variable rather than an attempt to call the trainingOptions function. Rename or remove the variable then run that code again.

still showing the same error :(

Show us the full error message (everything displayed in red text.)

Are you certain it is this call to trainingOptions that's throwing the error?

Did you rename or remove the variable from the workspace but not modify the code that precedes this line (which recreates that variable when you run it again?)
