Cannot load dbfload.py

I was trying to open dbfload from the directory, but the following error appears:

python dbfload.py
Traceback (most recent call last):
File "dbfload.py", line 261, in
d1 = DbfLoader('data/geoda/nat.dbf')
File "dbfload.py", line 65, in init
if (dbfFileName): self.loadDbfFileName(dbfFileName)
File "dbfload.py", line 70, in loadDbfFileName
dbfs = open(dbfFileName, 'rb')
FileNotFoundError: [Errno 2] No such file or directory: 'data/geoda/nat.dbf'

Hi, there are several questions you might help me answer to figure out what really happens.
First, to start GUI, you need to
python main_menu.py
Second, can you check if the path of nat.dbf is correct?
Can you run a pwd to make sure you are on the right relative path?

Hi, I started the GUI and it opened correctly. My mistake was opening the dbfload.py file first. If I am understanding correctly, the GUI uses the dbfload.py to run correctly?
