I train a model and save the state_dict after training and evaluating it upto a particular accuracy measure. When I reload the  state_dict onto a model and re-evaluate the evaluation changes drastically sometimes for better accuracy and sometimes to lower accuracy. I have even removed dropout and tried just to be thorough. It still happens.
The f1score and accuracies on the 5th epoch of First run and 0th epoch of second run should be same. What am I missing here?
