No such file or directory

Question

I can’t run my python file due to error saying

File "Application.py", line 32, in __init__
self.json_file = open("Modelsmodel_new.json", "r")
FileNotFoundError: [Errno 2] No such file or directory: 'Models\model_new.json'

This is my program code

class Application:

def __init__(self):

    self.hs = Hunspell('en_US')
    self.vs = cv2.VideoCapture(0)
    self.current_image = None
    self.current_image2 = None
    self.json_file = open("Modelsmodel_new.json", "r")
    self.model_json = self.json_file.read()
    self.json_file.close()

    self.loaded_model = model_from_json(self.model_json)
    self.loaded_model.load_weights("Modelsmodel_new.h5")

I’m using Ubuntu 22.04 LTS, and this is my
path folder

Answer 1

You need to make sure you’re running your script in the directory you intend to. You can check this by running os.getcwd() or Path.cwd() to see where the interpreter currently is.

Secondly, since you’re on Ubuntu, you’re going to have to change the backslash to a forwardslash, so that your path will be:

open("Models/model_new.json")

Answer 2

In Linux, your directories are separated by a forward slash. So your path would be: Models/model_new.json.

To make your python-scripts work on different operating systems, you can use the os-module:

import os

path = os.path.join("Models", "model_new.json")
self.json_file = open(path, "r")

If you’re interested, where the second slash comes from: This happens, because is used as a special character in strings to represent e.g. newline n or a tab t among others. I don’t think, that there is one for m, so python still sees it as just a backslash, but to play it save python does escape the backslash using another one \. This is then the safe representation of a backslash in a string.

You can view this, when printing the repr of your string:

print(repr("Modelsmodel_new.json"))
>>> 'Models\model_new.json'
