I am trying to change the contents of a destination file with the help of some source file. When the work is done, I am making sure that I have closed all the files in code (ofcourse, I have made sure that it is not opened in any editor too.)
def write_to_file(self, _source_path, _destination_path):
f_source = open(_source_path, 'r')
f_destination = open(_destination_path, 'r')
f_temp = open(self.temp_path, 'w+')
while source_line or destination_line:...
f_temp.close()
f_destination.close()
f_source.close()
shutil.move(self.temp_path, _destination_path)
return
I am getting below error:

When working with

you have 2 options, be a hero and try to hunt down the process that is holding that file hostage or just restart your computer.
I usually go with the latter, restart

Premise
I'm trying to convert some PDF to images via pdf2image and poppler, to then run some computervision tasks on.
The conversion itsself works fine.
However, the conversion creates some artifacts for each page in the pdf as it is being converted, which I would like to be deleted at the end of the function. To facilitate this, I am using tempfile.TemporaryDirectory(). The function looks as follow:
with tempfile.TemporaryDirectory() as path:
images_from_path: [Image] = convert_from_path(
os.path.join(path_superfolder, "calibration_target.pdf"),
size=(2480, 3508),
output_folder=path, poppler_path=r'E:\poppler-22.04.0\Library\bin')
if len(images_from_path) >= page:
images_from_path[page - 1].save(os.path.join(path_superfolder, "result.jpg"))
Problem
The trouble is, that the program always crashes with the following errors, after transforming the PDF and writing the required image to a file.

When stepping through the cleanup routine, everything seems fine, the path is correct and it starts deleting files, until at some point the internal path variable gets jumbled up and the routine crashes, because obviously a file is not a directory. To me it seems like a race condition is causing problems here.
What I have already tried
Rewriting the function to not use with and instead explicitly call the routine with tmp_dir.cleanup()
Just creating the directory without populating it with the conversion artifacts. The cleanup works in this case.
The documentation for tempfile mentions Permission errors occuring when files are open. The files are however only used in this function and if this is what is causing the error, I am unsure where the files are still opened or which function is causing this. My suspicion of course would be the conversion function.
While experimenting some more and writing this question, I found a working solution:
with tempfile.TemporaryDirectory() as path:
images_from_path: [Image] = convert_from_path(
os.path.join(path_superfolder, f"calibration_target_{exam_type}.pdf"),
size=(2480, 3508),
output_folder=path, poppler_path=r'E:\poppler-22.04.0\Library\bin')
if len(images_from_path) >= page:
images_from_path[page - 1].save(os.path.join(path_superfolder, "result.jpg"))
images_from_path = []
It seems that somehow, the routine had trouble cleaning up, because the converted images, are actually the artifacts created by pdf2image and were still being held by my data structure. Resetting the data structure, before implicitly initiating the cleanup fixed the issue.
If there is a better way of tackling this issue, please do not hesitate to inform me.
I have been using python OCR code to extract text from the image but i am getting some error. I think error is with subprocess library, however it is built in library. So i couldn't figure out the error exactly. can anyone please help me in resolving this error. My code and error are as below.
OCR code
import os
import tempfile
import subprocess
def ocr(path):
temp = tempfile.NamedTemporaryFile(delete=False)
process = subprocess.Popen(['tesseract', path, temp.name], stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
process.communicate()
with open(temp.name + '.txt', 'r') as handle:
contents = handle.read()
os.remove(temp.name + '.txt')
os.remove(temp.name)
return contents
str = ocr("C:\\Users\\hp\\Desktop\\MS Thesis\\opencv-text-detection\\opencv-text-detection\\images\\sign.jpg")
print(str)
by executing th above code I got following error

FileNotFoundError: [WinError 2] The system cannot find the file specified
I have been using Python 3.7.1 with anaconda on window 7
Look like there is an error because it cannot found the file
if the file is in the same directory I will recommend you use:
import os
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
os.path.join(BASE_DIR, 'file_dir')
I want to use this script to convert a mp3 file to a wav file.
import pydub
from pydub import AudioSegment

sound = AudioSegment.from_mp3("筷子兄弟 - 小苹果.mp3")
sound.export("筷子兄弟 - 小苹果.wav", format="wav")
But the problem is my access is denied.

How can I possibly fix the problem?
I tried out multiple solutions, which helped me, as follows:
Rebooting the computer and/or IDE,
Updating Python, IDE, computer,
pip install pydirectory (Command/Anaconda prompt, run as administrator)
Applying read permissions to the file,
Specifying the path to the file, and adding 'r' before the path, to indicate you want to 'read' the audio file, example at the bottom.
I hope this helps you or at least someone else running into this error.
Best of luck.
Source
Example, run in the same folder as the audio file:
from pydub import AudioSegment
import os
os.chmod('audio2.mp3', 777) #You might not need this
sound = AudioSegment.from_mp3(r"D:/audio.mp3")
#Put the 'r' in front of the filepath, to 'read' the audio file.
sound.export("audio.wav", format="wav")

I have looked at other questions with "broken pipe error": here,here, and here. But none of them are helpful to me.
Any indication on how to solve would be very helpful.
PyNomo uses a TeX installation to typeset text. Maybe this is missing resulting in a broken pipe. You need to be able to run a file hello.tex with the content Hello, world!\bye on a command line tex hello.tex. It should result in a file hello.dvi. If not you need to install a TeX distribution like TeXLive.

The file's name and the path are correct... I don't know what to do
Thank you
I think you should double check the path you provided.
You can access the file's parent folder using terminal, and the use command pwd to get the real path. Then compare it with the one in your code.
And I noticed you use "/users/". Is that correct? On my Mac OSX, it is /Users/. The path is case sensitive.
If this is a Linux or other Unix system you have the letter-case wrong in your open(); it should be Users not users. File and directory names are case-significant in Unix.
