Hi,

Got this error when running rosrun loop_hloc loop_hloc_node ./src/ov_hloc/config/master_config.yaml:

Any ideas?

Thanks for trying to run my code!

It appears that the error is occurring during the loading of the SuperPoint model. Have you properly converted the model? Please ensure that the correctly converted model file exists in the path specified by this macro definition.

https://github.com/Li-Jesse-Jiaze/ov_hloc/blob/e4663253b3803ff1f9f2055b3b5e481bcf2eb425/loop_hloc/src/hloc/hloc.h#L12-L15

The default path here is the one in my computer. Sorry I didn't use a better way to read the relative path, you may need to change it.

If you are still encountering errors, please provide additional information so that I can offer further assistance.
