How to access model weights in Tkinter exe file?

Question

I have generated an Tkinter GUI and generated one exe file that copied model weights.

the weights folder is in the same folder of the myTKcode.py file.

I generate my model as and load weights as below:

import tensorflow as tf
model = MyModel()
model.load_weights("weights/MyModelWeights")

Now if I use pyinstaller to generate an exe file as below:

pyinstaller --onefile --add-data weights;weights myTKcode.py

Based on the size of the myTKcode.exe file I can say that weights have been added in the myTKcode.exe. But when I run the myTKcode.exe file, it does not find the weights folder. But if I copy paste the weights folder in the dist folder where myTKcode.exe is, it works.

my question is how access the weights stored in the myTKcode.exe?

Always use absolute paths instead of relative paths. You may need a environment variable or a command line argument sur specify you “working” directory. — Laurent LAPORTE, May 02 '21 at 21:05
I know that this is a terrible idea but theoretically can't you base 64 encode the weights and hard code them in your program? After that you can just expand them in a temp folder at runtime? — TheLizzard, May 02 '21 at 21:09

Similar questions have been asked previously and found the solution here.

In brief, for each folder/file an absolute path has to be added to standalone exe file.

as I have a single folder named weights; I simply add the following code to my code:

def resource_path(relative_path):
    """ Get absolute path to resource, works for dev and for PyInstaller """
    base_path = getattr(sys, '_MEIPASS', os.path.dirname(os.path.abspath(__file__)))
    return os.path.join(base_path, relative_path)

then I loaded weights as below;

import tensorflow as tf
model = MyModel()
#model.load_weights("weights/MyModelWeights")
weightDir = resource_path("weights") # resource_path get the correct path for weights directory.
model.load_weights(weightDir+"/MyModelWeights")

and then simply run pyinstaller as below:

pyinstaller --onefile --add-data weights;weights myTKcode.py
