The system cannot find the file specified (Python 3) - python

I'm trying read texts from an image using pytesseract but it throws this error no matter what I try.
Code:
import os
import subprocess
import pytesseract
from PIL import Image
subprocess.call('dir', shell=True)
print(os.path.isfile("test.jpg")) #True
im = Image.open("test.jpg")
text = pytesseract.image_to_string(im)
OUTPUT:
Traceback (most recent call last):
File "F:/Programming/PYTHON/captcha/test/main.py", line 10, in <module>
text = pytesseract.image_to_string(im)
File "F:\Program Files (64bit)\Python\lib\site-packages\pytesseract\pytesseract.py", line 193, in image_to_string

startupinfo)
FileNotFoundError: [WinError 2] The system cannot find the file specified
Process finished with exit code 1
what's wrong? I know that file is there. I checked it using os.path.isfile and subprocess call
Other things that I tried:
-added full image file path using string literal 'r'
-tried different images and file types

PermissionError: [Errno 13] when using tkinter for an image

Hello I am trying to make a python script that takes an image file from a computer and turn it into text. At the moment, I have the following code
from tkinter import Tk
from tkinter.filedialog import askopenfilename
import pytesseract
Tk().withdraw()
filename = askopenfilename()
print(filename)
pytesseract.pytesseract.tesseract_cmd = filename
print(pytesseract.image_to_string(filename))
However this gives me the error
Traceback (most recent call last):
File "main.py", line 11, in <module>

What am I doing wrong?
this: pytesseract.pytesseract.tesseract_cmd = filename is absolutely wrong.
tesseract_cmd should have your tesseract engine executable path.
you need to find where you installed tesseract.
pytesseract.pytesseract.tesseract_cmd = <path_to_tesseract_engine>
# example
# pytesseract.pytesseract.tesseract_cmd = "/some_folder1/some_folder2/...
# /<where_you_installed_tesseract_cmd>/tesseract.<whatever_is_the_extension_for_executables_on_mac>"
you get permission error because you set the tesseract_cmd to link the path to your image and when you actually use pytesseract.image_to_string(<your_image>) ofcourse it raises permission denied because the image is used by the tesseract_cmd process.
after you set your engine.
this is gonna be fine
print(pytesseract.image_to_string(filename))

I'm using pytesseract in Python for pdf. But I'm getting permission error in windows 10.

AttributeError using python module py3270

As a part of some automation I am trying to connect to mainframe using python, where I can access the mainframe files and create a
report. Just like using mainframe files as DB for python program.
To login to mainframe - we need to provide host details(xyz.host.com)
followed with region details(h123p) and then with our credentials.
I found that we can do this using python package py3270 and tried doing it but getting the error.
from py3270 import Emulator
# or not (uses s3270)
em = Emulator()
em.connect('xyx.example.com')
em.fill_field(3, 1, 'xxxx',5)
em.send_enter()
em.fill_field(2, 1, 'xxxxxxx', 7)
em.send_enter()
em.fill_field(8, 20, 'xxxxxxxx', 8)
em.send_enter()
# if your host unlocks the keyboard before truly being ready you can use:
em.wait_for_field()
# maybe look for a status message
if not em.string_found(1, 2, 'login succesful'):
abort()
# do something useful
# disconnect from host and kill subprocess
em.terminate()
The error:
File "C:/Users/vganr/PycharmProjects/test/mainframe.py", line 6, in

Based on the error messages you're seeing, I suspect you're having a problem with missing/not found x3270/s3270 libraries.

The above suggests that the library is trying to start Ws3270, the windows version of x3270, and is unable to do so.
Make sure the the required libraries are in your path and visible from python.

Psychopy gives the ffmpeg error and does not play the videos

I want to create an experiment with Psychopy in which I will present randomly video that participant will have to evaluate.
I have created a routine with my MovieStim and my Rating response and a Loop with my conditions file (in which are my video files videoname.wmv).
All my videos are in the same folder as my experiment.
I have specified the MovieStim with a variable refering to my Loop's column ($Stimulus).
But when I run the experiment I have this message.

It seems to be something wrong with the ffmpeg executable but I don't understand what.
Do you have any idea ?
Thank you very much fo advance !
Have a nice day.

Getting OSError: [Errno 2] No such file or directory

I try to use osm-bundler:

File permissions are set correctly.
It looks like you did only install osm-bundler.zip and not osm-budler-full.zip. The line with the self.executable tries to execute sift, which is expected at /home/ubuntu/osm-bundler/software/sift-lowe/sift. This is most probably not installed (I tried it myself with osm-bundler.zip and this was missing).
