Assertion Error in 'prepare_data.py'

[Rishika-Rathore]

Used this code as specified but got an assertion error.
I have also kept the files in the directory as specified.
I ran the command python prepare_data.py --data_path ~/Dota/dataset/ --num_process 32

The output that I got after running the script:
