Python 中打开文件错误：没有这样的文件或目录

Question

I'm a newbie for writing here. So please please be bear with me.

I'm running this code to open my file and I put this in right directory 'data'. But my python sent me error message continuely.

I wrote this,

#file = unidecode.unidecode(open('./data/input.txt').read())
#file = unidecode.unidecode(open('./data/linux.txt').read())

file = unidecode.unidecode(open('./data/hh1.txt').read())
file_len = len(file)
print('file_len =', file_len)

and poped up this

---------------------------------------------------------------------------
FileNotFoundError                         Traceback (most recent call last)
<ipython-input-36-aa7f0f650918> in <module>()
  4 #file = unidecode.unidecode(open('./data/linux.txt').read())
  5 
  ----> 6 file = unidecode.unidecode(open('./data/hh1.txt').read())
  7 file_len = len(file)
  8 print('file_len =', file_len)

 FileNotFoundError: [Errno 2] No such file or directory: './data/hh1.txt

code image directory

It's part of RNN(Recurrent Neural Network) code and it's part of processing text data to learn knitting pattern.

It's very simple error but I can't find a good way out.... So thank you for your patient to read this and I hope someone could help me out

Answer 1

You're trying to open a file that is inside data folder in your relative path.

open('./data/hh1.txt').read()

If your script is in

/home/user/test.py

This one tries to open:

/home/user/data/hh1.txt

And if you use

open('./hh1.txt').read()

This one tries to open

/home/user/hh1.txt

That is in the same directory of your script.

You can use:

import os
print(os.listdir())

And it will show you all files in the current directory.

If you're using a relative path, check the path from your current directory to the destination file.

Answer 2

It's likely that the path that you have entered is being interpreted differently than expected. This depends on a variety of this such as where the Python file you are executing is and whether it is part of a bigger project.

A good way to debug this is to expand the path you are trying to use into its absolute path. You can do this using the following code:

import os
print(os.path.abspath("./data/hh1.txt"))

This will output something like "/home/user/project/data/hh1.txt" .

You can check the output of this and verify that your files are in the right location or if your path is possibly incorrect.
