"Hello, I have recently read your paper 'CoHOG: A Light-Weight, Compute-Efficient, and Training-Free Visual Place Recognition Technique for Changing Environments' and am very interested in it. I would like to run the open-source code you provided on GitHub. However, in the main.py file, I found these two lines of code for importing packages:

from Hog_feature.Hog_feature.hog import initialize from Hog_feature.Hog_feature.hog import extract

I am unable to locate the files at the path Hog_feature.Hog_feature.hog. Could you please advise how to resolve this issue?"

Hey, thanks for your interest. Yes, it's already in the repo. See here.

I found these files in this zip, where hog is a .so file, do I need to import this so file first before I import the package? image image

No, just extract the Zip folder in the directory. The paths will work as is, you don't need to change anything, just need to extract the Zip folder.

A .so is a Python library file, you can import it like a typical Python module.

MubarizZaffar commented 1 month ago

Looks like a Cython compilation error. Perhaps you are running the Python 2 version with Python 3? There is also a separate Python3 compiled version available.

Even if you don't want to use the Cython compiled libraries, the source code is also available for the library in this repo.

Thank you very much for your reply again. At first I did use python3.10 to run python2, but I immediately found the problem and used python3.10 to run python3, but the problem still occurs.
