Assertion Failed Exception !

[HanyHossny]

I tried to run this code multiple times, but I always get the exception below and none of the fixes mentioned online worked with it. Would you take a look into it and tell how to fix this ??

===================================
%run ./index.py --dataset "./dataset" --save "./results"
Start Processing

Hello you have to add * .extension in the dataset

"%run ./index.py -- dataset "./dataset/*.jpg" --save "./results"
