"Error when checking input: expected input_1 to have shape (299, 299, 3) but got array with shape (28, 28, 1)"

I get following error when i run the code. 
"Error when checking input: expected input_1 to have shape (299, 299, 3) but got array with shape (28, 28, 1)"

I cannot change the inception_resnet_v1 code as it has a default size, what can I do to fix this problem?
