Why i am getting less performance than yours?

[AliSaeed86]

Hi,
I run the code published in this repo, but i didn't get the same performance as mentioned in Performance.txt file.
i just copied and pasted the code and corrected some typos like putting ( ) for print function and just made it run.
i used Colab Pro in the implementation and the results of DRIVE dataset is as follow:

Area under the ROC curve: 0.9745132983506472
Area under Precision-Recall curve: 0.9005084432534444
Global Accuracy: 0.9542264313839384
Specificity: 0.9833227875108509
Sensitivity: 0.7547351419287491
Precision: 0.8684320607463418
Jaccard similarity score: 0.6772917155378523
F1 score (F-measure): 0.807601574924213 

Also, i tried to load the test_best_weights.h5 to see the prediction's of your trained model (without retraining from scratch), but i also get the below error while reading test_architecture.json file, so i couldn't even load your trained model and evaluated.

ValueError: ('Unrecognized keyword arguments:', dict_keys(['input_dtype']))

Please, what should i do to get the same performance as yours ?
Any help is appreciated.
Thanks
