Evaluation FID score is lower than paper

[gkalstn000]

I checked the previous issues that some people have trouble with evaluating code.
So I resized the gt image and real image to 256x256 in two ways, bilinear and bicubic.
I got an FID score of 14.101 but in your paper is 10.573.
Did you change the pre-trained parameters?
I didn't change any options in your code. I just download the pre-trained parameters and run the code.
please help me...
