Having trouble running this same code

I am getting alot of error while running the same code. It is giving tha NaN error in longitude,latitude in df_main and the pkl file is also giving error. I am aware that this project is 2 years old but can you help me lil bit in figuring out the error and resolving this?

The issue mentions NaN errors in longitude/latitude columns in df_main and errors with a pkl file. First, locate the data processing scripts (likely in Jupyter notebooks or Python files) that load sensor data and create df_main. Check for missing data handling and serialization/deserialization logic. Running the existing code to reproduce the errors is the first step, but the project is 2 years old and dependencies may have broken.
