Formatting: output for compare_samples diagonal is not zero

The output for the compare_samples command is not zero when showing the diagonal of the All vs All comparison in all pipelines.

Bad formatting example with mobilefacenet pipeline:

All vs All comparison
------------------  -----------------------
./me.jpg            ./not_me.jpg
-0.0                -0.9227539984332366
-0.922753991574597  -3.5416114485542494e-14
------------------  -----------------------

However it is correct with resnet50-msceleb-arcface-2021 pipeline:

All vs All comparison
-----------------  -----------------
./me.jpg           ./not_me.jpg
-0.0               -1.03846231201703
-1.03846231201703  -0.0
-----------------  -----------------

So far I have only tested a few pipelines

• Bad formatting: facenet_sanderberg, arcface-insightface, mobilefacenet
• Correct formatting: resnet50-msceleb-arcface-2021, resnet50-msceleb-arcface20210521
