Database uploaded but not able to work on that

Respected;
Hope you are fine and doing well. Actually, when I created a database in CSV file then I can do the things that I want in Neo4j. But when uploading a dataset in Neo4j related to the video violence dataset(available: GitHub - airtlab/A-Dataset-for-Automatic-Violence-Detection-in-Videos). then there is the problem while accessing in Neo4j.
