Model size issue

I am trying to train the person detector model for sparkfun edge board using the github documentation ( I am currently at section “Converting into a C source file” where I generate the file.
In the generated file I see the size of the model as 300536 as indicated by the following line in the c file:
unsigned int vww_96_grayscale_quantized_tflite_len = 300536;

However, when I check the original file available at tensorflow/lite/micro/tools/make/downloads/person_model_grayscale/,
I see the model size as 236072, because of the following line:
const int g_person_detect_model_data_len = 236072;

Can anyone please let me know why this difference might be arising?

PS: I am using tensorflow version 1.15
