Bad results using EfficientNet B0

[virilo]

I'm trying to reproduce this script: https://www.kaggle.com/meaninglesslives/efficientnet-gradcam-comparison-to-other-models

To make it work with current EfficientNet version, I'm using the layer model._blocks[-1]._project_conv. I also tried this solution, having the same results

But the results doesn't seem too good, compared to the results of the original script.

You can compare it with the original script results, showing what one can expect from GradCAM
