The file location format is not correct. In windows you can’t do it like it.
1st solution will be, save the model relative to the code directory. then don’t need to give full path like c:.
2nd
Try path like this C:/Users/myName/My Documents. “/” instead of “”.
3rd
Compose a path like raw string
model_loc = r"C:\Users\myName\My Documents"
I feel first method is easier and simple.
