Hi DeepLearning.AI Team,

I completed the Week 4 Saliency Maps assignment, followed all lab instructions, and generated the required images with the correct filenames and prefix. I zipped the files as images.zip and submitted them.

The grader reports an average SSIM of 0.88, which meets the minimum requirement, but my submission is still marked as failing.

Could you please help me understand why my submission might not be passing?

Thank you!  
Tahzeeb Ul Hassan

Apparently that’s a typo, and it should say 'Greater than 0.88 …"
