I have tried to find the solution on internet, but i am unable to get any solution. Plese help to resolve the problem! What is causing it?
I am trying to execute the following bash command in python using the subprocess python package but its throwing me an error.
the bashCommand variable in the following code stores the bash command i'm trying to execute
def desc_calc():
bashCommand = "java -Xms2G -Xmx2G -Djava.awt.headless=true -jar ./PaDEL-Descriptor/PaDEL-Descriptor.jar -removesalt -standardizenitro -fingerprints -descriptortypes ./PaDEL-Descriptor/PubchemFingerprinter.xml -dir ./ -file descriptors_output.csv"
process = subprocess.Popen(bashCommand.split(), stdout=subprocess.PIPE)
output, error = process.communicate()
upon running the code, i get the following error:

I am trying to open a shortcut for Notepad called Notepad.lnk.
Because I want to learn how to open applications so I can use the pygui library to manipulate them.
Got FileNotFoundError
I got this error:
Traceback (most recent call last):
File "C:\Users\{my_name}\PycharmProjects\texture-gen\main.py", line 185, in <module>
subprocess.run(['start', shortcut_path], check=True)
File "C:\Users\{my_name}\AppData\Local\Programs\Python\Python39\lib\subprocess.py", line 505, in run

hp, ht, pid, tid = _winapi.CreateProcess(executable, args,
FileNotFoundError: [WinError 2] The system cannot find the file specified
Code
This is my python code:
if __name__ == '__main__':
import os
import subprocess
cwd = os.getcwd()
shortcut_path = os.path.join(cwd, 'Notepad.lnk')
if not os.path.exists(shortcut_path):
print('Error: "Notepad.lnk" shortcut not found')
subprocess.run(['start', shortcut_path], check=True)
Debugging
I have checked the name of the shortcut is Notepad.lnk and is in the current working directory.
Why is this not working?
I know this has been answered but nothing works, I run my code
import pytesseract
import cv2
pytesseract.pytesseract.tesseract_cmd = r"C:\\Users\\aidan\\AppData\\Local\\Tesseract-OCR"
image = cv2.imread(r'C:\Users\aidan\OneDrive\Desktop\download.jpg')
cv2.cvtColor(image,cv2.COLOR_BGR2RGB)
print(pytesseract.image_to_string(image))
cv2.imshow('Result',image)
cv2.waitKey()
and I always get this error
[ WARN:0#0.043] global D:\a\opencv-python\opencv-python\opencv\modules\imgcodecs\src\loadsave.cpp (239) cv::findDecoder imread_('download.jpg'): can't open/read file: check file path/integrity

how can I fix this?
You have dropped the executable in the cmd-variable:
pytesseract.pytesseract.tesseract_cmd = r"C:\Users\aidan\AppData\Local\Tesseract-OCR\tesseract.exe"
I tried invoking bootsect.exe with subprocess.Popen, subprocess.run, subprocess.call, or even os.system but I keep getting the error below...
File "<stdin>", line 1, in <module>

FileNotFoundError: [WinError 2] The system cannot find the file specified
For instance, I get this error if use the code below...
import subprocess
subprocess.Popen('bootsect')
I can run diskpart or cmd using Popen but not bootsect for some reason. Any thoughts?
