with no file ".npy"

[zr19980402]

They say CANNOT load .npy file.

[zr19980402]

I have found the wrong: when running the code, there is no track.

[zr19980402]

After some attempts, the issue became a new. I cannot run the HLOC features.

Can you post a minimal example to reproduce this error?

[zr19980402]

First, I use the open dataset "books" as the input.
other settings are shown in figure 1.

and I print the "output1" "output2" "output3"
figure2-figure3

some details!
1.system: VMware Workstation Ubuntu20.04
2.Hloc version: Hierarchical-Localization-pairs_from_sequence ( This version only add the pairs from sequence)
3. I have use the Recommended Hloc version as the same setting. the error is shown on the Last comment.

From the error message in figure 2, it seems that the D2Net feature extractor is not installed correctly in hloc. I did a quick fix to make the codebase compatible with the new hloc interface. I pushed it to the branch new_hloc. Can you install the current version of hloc according to its install.md and try the codebase on this new branch?

[zr19980402]

OK。I will try it at next day

[zr19980402]

Thanks！ I have not seen this news,
sorry.

[zr19980402]

Make it! Thanks for your general answer！
Best wishes!

And there may be a little misktake. In your /extract_match_features.py line 16-18~

assert feature_type in [
'sift_default', 'sift_sparse', 'superpoint', 'r2d2', 'd2net', 'disk'
# 'sift_default', 'sift_strict', 'superpoint', 'r2d2', 'd2net', 'disk'
]

Indeed it is a typo. Thanks for pointing it out!
