Bad result in Aachen v1.1

[Adolfhill]

Hello, Thanks for your impressive work. When I try to test in aachen v1.1, I get a bad result. It is far away from the result in the paper.

I use the script with a little modification in order to adapt my system. ` #!/bin/bash dataset=./dataset image_dir=$dataset/images/images_upright outputs=./output query_pair=pairs/aachen_v1.1/pairs-query-netvlad50.txt gt_pose_fn=assets/Aachen-v1.1_hloc_superpoint_n4096_r1600+superglue_netvlad50.txt save_root=./output

If I fill the image with /dev/random, command touch or mkdir will error

Did you run mkfs.simplefs before mounting the image file?

[HotMercury]

Yes, following is my detail actions

$ dd if=/dev/random of=test.img bs=1M count=32
$ ./mkfs.simplefs test.img
$ mkdir test
$ sudo mount -t simplefs -o loop test.img test
$ cd test
[test] $ touch test.txt

the error message comes up, but if I replace /dev/random with /dev/zero, it will work correctly.
