Python - can't find file used in the imported file

Question

I loaded a file in a.py using panda:

candidates = pd.read_csv("../train_v1.csv")
model = ........

In b.py, I firstly import the a.py as:

import a as trained_model

Then, I called the model constructed in a.py. The system can't find the file that I loaded in a.py, and gave:

FileNotFoundError: [Errno 2] No such file or directory: '../train_v1.csv'

How should I get this to work?

Answer 1

Try to use the aboslute path. Example your project directory is C:\Test\project\ your file is in the directory C\Test\data\ and called train_v1.csv

then do not use the relative path ../data/train_v1.csv
use C:\Test\data\train_v1.csv
