📚 The doc issue

Hi,

I found some objects annotated in the MMScan_VG.json or MMScan_Caption_object.json that don't exist in embodiedscan_infos_train.pkl or embodiedscan_infos_val.pkl.

For instance, there is an object with object_id=39 in scannet/scene0195_00 listed in MMScan_Caption_object.json. However, I cannot find this object in embodiedscan_infos_train.pkl. Is this normal, or did I miss something?

Looking forward to your response, and thanks in advance.

Suggest a potential alternative/fix

Thank you for pointing out this issue!

In the VG/Caption annotation files, there are a very small number of cases where certain objects cannot be found in the embodiedScan PKL files. For these instances, please prioritize the PKL annotations and simply skip the samples with missing objects—this will not affect the use of the dataset. (We have also implemented a filtering mechanism in MMScan's data loading tools to handle this issue.)

The reason for this problem is that we manually removed a very small number of controversial object annotations. We will also upload the filtered annotation files later.
