WinError 5:Access denied PyTesseract

I know this question has already been answered on this site, however, none of the solutions I looke up the internet seemed to work. Here's what I tried:
Giving all permissions to my python file
Changing PATH variable to point to my tesseract folder
Running IDLE as administrator and then executing the file from there
This error is quite bothering me now and I can't advance any further because of it.
Here's my code if that's going to help:
import pytesseract
import sys
import argparse
try:
import Image
except ImportError:
from PIL import Image
from subprocess import check_output
pytesseract.pytesseract.tesseract_cmd = 'C:\Program Files\Tesseract-OCR'
c=pytesseract.image_to_string(Image.open('img.png'))
print(c)
Traceback:

PermissionError: [WinError 5] Accès refusé

I encountered same problem, and I fixed it as 0xc0de said, change the below line:
pytesseract.pytesseract.tesseract_cmd=r"C:\MyApps\Tesseract-ocr\"
to:
pytesseract.pytesseract.tesseract_cmd="C:\\MyApps\\Tesseract-ocr\\tesseract.exe"

I suspect a few things, not sure about any though.
First and the most obvious, the path to Tesseract is not complete. It should be something like:
tesseract_cmd = 'C:\\Program Files (x86)\\Tesseract-OCR\\tesseract'
I believe your path points to a directory/folder and not an executable, though only you can confirm that. Let me know if this is incorrect, I see something else too that doesn't seem right at first, but needs more investigation.

Use this to read the tesseract path and also make sure that you have installed the Tesseract- OCR
pytesseract.pytesseract.tesseract_cmd = r'C:\\\Program Files (x86)\\\Tesseract-OCR\\\tesseract.exe'
using always double \\ instead of a single "\"

You need to install tesseract separately. I am providing the link from where you should install
https://github.com/UB-Mannheim/tesseract/wiki
tesseract-ocr-w32-setup-v5.0.0-alpha.20201127.exe (32 bit) and
tesseract-ocr-w64-setup-v5.0.0-alpha.20201127.exe (64 bit) resp.
choose here according to your system config. most of us have 64 bit. so choose that.
Install the file very carefully. I Would suggest doing it in a separate drive other than c.
take the path where you have install the tesseract.exe file. and paste it at pytesseract.pytesseract.tesseract_cmd
look the code...
import cv2
import pytesseract
pytesseract.pytesseract.tesseract_cmd = r'E:/OCR/tesseract_install/tesseract.exe'
img = cv2.imread('E:/OCR/example1.png')
# to see the image below codes are there
cv2.imshow('sampleimage',img)
#enter any key to destroy the image window opened due to previous line code
cv2.waitKey(0)
cv2.destroyAllWindows()
#convert image to text using tesseract
text = pytesseract.image_to_string(img)
print(text)

I had this issues pretty consistent, and I fix it without any access change.
The trick is:
1: You need to install tesseract and remember where is path to tesseract.exe file.
2: Then install pytesseract on exect environment you going to use it using pip install pytesseract
3: Do not add any Path to your System Env variables, it will mess up with everything.
4: CLEARLY define path to image file, or even better if image will be in closest/the same directory where is your python code.
from PIL import Image
import pytesseract
pytesseract.pytesseract.tesseract_cmd=r'C:/Users/your_name/AppData/Local/Programs/Tesseract-OCR/tesseract'
#this path to image
path = r'C:\Users\irina_max\Documents\Python_Scripts\Invoice 1.jpg'
image= Image.open(path)
image

Install the tesseract exe in a directory inside your project. I did the above and it worked fine, without giving Win 5 error.

The system cannot find the file specified with ffmpeg

In the process of using the ffmpeg module to edit video files i used the subprocess module
The code is as follows:
#trim bit
import subprocess
import os
seconds = "4"
mypath=os.path.abspath('trial.mp4')
subprocess.call(['ffmpeg', '-i',mypath, '-ss', seconds, 'trimmed.mp4'])
Error message:
Traceback (most recent call last):

WindowsError: [Error 2] The system cannot find the file specified
After looking up similar problems i understood that the module is unable to pick the video file because it needs its path, so i took the absolute path. But in spite of that the error still shows up.
The module where this code was saved and the video file trial.mp4 are in the same folder.

The WindowsError you see does not refer to the video file but to the ffmpeg executable itself. The call to subprocess.call has no idea that trimmed.mp4 is a filename you are passing. Windows knows that the first parameter ought to be an executable file and reports back to the interpreter that it can't find it.
Double-check that ffmpeg can be executed in the environment your interpreter is running in. You may either add it to your PATH or specify the full path to ffmpeg.exe.

None of the above answers worked for me.
I got it working, by opening Anaconda Navigator > CMD prompt.
conda install ffmpeg

This answer is directed at Windows users of the ffmpeg-python library since this question is the first search result for a stricter instance of the same issue.
Adding on to user2722968's answer because neither of the existing answers solved the problem for me.
As of this post, ffmpeg-python uses subprocess.Popen to run ffmpeg. Per this issue, subprocess does not look in Path when resolving names, so even if FFmpeg is installed and in your Path and you can run it from CMD/PowerShell, ffmpeg-python may not be able to use it.
My solution was to copy ffmpeg.exe into the Python environment where python.exe is. This workaround seems far from ideal but it seems to have solved the problem for me.

Most of the answers didn't work. Here is what worked for me using conda env:
pip uninstall ffmpeg-python
conda install ffmpeg
pip install ffmpeg-python
Just the conda installation gives library not found error. Didn't try uninstalling conda library either but this works.

I had the same issue!
And I FOUND A SOLUTION.
I realised, viewing all these answers that I need to install ffmpeg. I tried 'pip install ffmpeg' but that didn't work. What worked was copying the ffmpeg.exe file to the folder that python.exe is in.
Thats what someone up here mentioned. Thank you!
To download the ffmpeg.exe file, download the zip file from https://github.com/GyanD/codexffmpeg/releases/tag/2022-06-06-git-73302aa193

First Uninstall all pip libraries
pip uninstall ffmpeg
pip uninstall ffmpeg-python
Then install using conda
conda install ffmpeg

If you are going to use 'ffmpeg.exe' or its linux binary, you need this
conda install ffmpeg
Then you will call it via subprocess or os.system() in your code.
And make sure you will run a different thread to run ffmpeg code otherwise there will be a huge bottleneck in your main thread.
class SaveAll():
def init(self):
super(SaveAll, self).__init__()
def save(self):
try:
command = "ffmpeg -i {} -c copy -preset ultrafast {}"format(...)
os.system(command)
except ffmpeg.Error as e:
print (e.stout, file=sys.stderr)
print (e.stderr, file=sys.stderr)
def run(self):
self.thread= threading.Thread(target=self.save)
self.thread.start()
self.thread.join(1)
...
saver = SaveAll()
saver.start()

raise NeedDownloadError('Need ffmpeg exe. ' NeedDownloadError: Need ffmpeg exe)

I'm trying to execute a call to an unofficial Instagram API python library, after several errors for dependencies needed I fixed, I'm stuck at this one.

raise NeedDownloadError('Need ffmpeg exe. '
NeedDownloadError: Need ffmpeg exe. You can download it by calling:
imageio.plugins.ffmpeg.download()

Those final two lines in the error messages provide a valuable clue, and I installed moviepy only today so I remember a remedy.
NeedDownloadError: Need ffmpeg exe. You can download it by calling:
imageio.plugins.ffmpeg.download()
First (sudo) pip install imageio, if necessary.
Now: import imageio and then imageio.plugins.ffmpeg.download().

If you are using Ubuntu just try:
sudo apt-get install ffmpeg
Else if you are using Windows just try to change ffmpeg.py 82th line from auto=False to auto=True
It will automatically download ffmpeg to the correct path once. Then import imageio and write down imageio.plugins.ffmpeg.download()
Will work.

This package relies on the ffmpeg executable to be in the PATH.
So just download it, install it somewhere, and add installation directory to PATH. make sure it can be accessed by typing:
ffmpeg
from the command line.

For anyone using a mac do this.
pip install imageio (if not already installed).
Then create a .py file (python script).
In this file write this:
import imageio
imageio.plugins.ffmpeg.download()
Run this script in the terminal (i.e "python (insert .py filename here)" )
It installs FFmpeg in a directory that should be automatically added to your path. If not, add it to your path.
Then type
ffmpeg
to make sure it's installed in your path.

At Windows, I'd fix this that way:
Manual download ffmpg from github
In the Lib\site-packages\imageio\plugins\ffmpeg.py file, change
exe = get_remote_file('ffmpeg/' + FNAME_PER_PLATFORM[plat], auto=False)
to
exe = "PATH_WITH_FFMPG\\ffmpeg.win32.exe"

on mac,
this is the best way to install ffmpeg.
Open terminal and type.
$ brew install ffmpeg
you will be seeing it get installed.

Can't create pdf using python PDFKIT Error : " No wkhtmltopdf executable found:"

I tried installing pdfkit Python API in my windows 8 machine. I'm getting issues related to path.
Traceback (most recent call last):

IOError: No wkhtmltopdf executable found: ""
If this file exists please check that this process can read it. Otherwise please install wkhtmltopdf - https://github.com/JazzCore/python-pdfkit/wiki/Installing-wkhtmltopdf
Is anybody installed Python PDFKIt in windows machine? How to resolve this error.
My sample code :
import pdfkit
import os
config = pdfkit.configuration(wkhtmltopdf='C:\\Python27\\wkhtmltopdf\bin\\wkhtmltopdf.exe')
pdfkit.from_url('http://google.com', 'out.pdf')

The following should work without needing to modify the windows environment variables:
import pdfkit
path_wkhtmltopdf = r'C:\Program Files (x86)\wkhtmltopdf\bin\wkhtmltopdf.exe'
config = pdfkit.configuration(wkhtmltopdf=path_wkhtmltopdf)
pdfkit.from_url("http://google.com", "out.pdf", configuration=config)
Assuming the path is correct of course (e.g. in my case it is r'C:\Program Files (x86)\wkhtmltopdf\bin\wkhtmltopdf.exe').

Please install wkhtmltopdf using,
sudo apt install -y wkhtmltopdf
for windows machine install it from below link, http://wkhtmltopdf.org/downloads.html
and you need to add wkhtmltopdf path into environment variables

IOError: 'No wkhtmltopdf executable found'
Make sure that you have wkhtmltopdf in your $PATH or set via custom configuration. where wkhtmltopdf in Windows or which wkhtmltopdf on Linux should return actual path to binary.
Adding this configuration line worked for me:
config = pdfkit.configuration(wkhtmltopdf="C:\\Program Files\\wkhtmltopdf\\bin\\wkhtmltopdf.exe")
pdfkit.from_string(html, 'MyPDF.pdf', configuration=config)
From github
Seems you need to pass configuration=config as argument.

I am learning python today, and I met the same problem, lately I set the windows enviroment variables and everything is OK.
I add the install path of wkhtml to the path, for example:"D:\developAssistTools\wkhtmltopdf\bin;" is my install path of wkhtml, and I add it to the path, everything is OK.
import pdfkit
pdfkit.from_url("http://google.com", "out.pdf")
finally, I find a out.pdf.

import pdfkit
path_wkthmltopdf = b'C:\Program Files\wkhtmltopdf\\bin\wkhtmltopdf.exe'
config = pdfkit.configuration(wkhtmltopdf=path_wkthmltopdf)
pdfkit.from_url("http://google.com", "rajul-url.pdf", configuration=config)
pdfkit.from_file("output.xml","rajul-pdf.pdf", configuration=config)
The Above Code block is working perfectly fine for me. Please note that file which needs to be converted is in the same directory where the pdf file is creating.

Ran into the same problem on a Mac. For some reason-- it worked after unistalling the pip installation and reinstall wkhtmltopdf using brew
pip uninstall wthtmltopdf
and use brew
brew install Caskroom/cask/wkhtmltopdf

You need set:
pdfkit.from_url('http://google.com', 'out.pdf',configuration=config)

Found the decode on a windows platform needed to be a binary string, try:
path_wkthmltopdf = b'C:\Program Files\wkhtmltopdf\\bin\wkhtmltopdf.exe'
config = pdfkit.configuration(wkhtmltopdf=path_wkthmltopdf)
pdfkit.from_url(url=urlpath, output_path=pdffilepath,configuration=config)

def urltopdf(url,pdffile):
import pdfkit
'''
input
- url : target url
- pdffile : target pdf file name
'''
path_wkthmltopdf = 'D:\\Program Files (x86)\\wkhtmltopdf\\bin\\wkhtmltopdf.exe'
config = pdfkit.configuration(wkhtmltopdf=path_wkthmltopdf)
#pdfkit.from_url(url=urlpath, output_path=pdffilepath,configuration=config)
pdfkit.from_url(url,pdffile,configuration=config)
urltopdf('http://www.google.com','pdf/google.pdf')
very good solution!
thanks everyone!

When I tried all of the above methods, I was till facing Permission Error as I don't have the admin rights to my workstation.
If that's the case for you too, then make sure when you install your wkhtmltopdf.exe. The destination folder for installation is in your python site-packages folder, or add the directory to sys.path.
Normally it gets installed in Program files folder.
I changed the installation directory and this works for me:
import pdfkit
pdfkit.from_url("http://google.com", "out.pdf")

[For Ubuntu/Debian]
first run: sudo apt-get update --fix-missing
then: sudo apt-get install -y wkhtmltopdf
hope it would solve your problem.

for windows Try to use the complete path C:\Program Files\wkhtmltopdf\bin\wkhtmltopdf.exe

No need to write wkhtmltopdf path into code. Just define an environment variable for that, and it works.
import pdfkit
pdfkit.from_url('http://google.com', 'out.pdf')
For me this code is working.

Python: Installation issues with pygraphviz and graphviz

I see many questions on the difficulties of properly installing pygraphviz and graphviz on Windows for Python 2.7. But no answers that I have found is solving my problem. Here's what I did:
I first installed pygraphviz using unofficial windows binaries
with this link in my anaconda (python) folder (
C:\Users\chamar\AppData\Local\Continuum\Anaconda )
Downloaded graphviz-2.36.msi and installed it under the default
path C:\Program Files (x86)\Graphviz2.36
The command import pygraphviz in Python works. But when I want to use say this function nx.graphviz_layout I get raise ValueError("Program %s not found in path."%prog)
What may cause this problem is that pygraphviz cannot locate the path of graphviz. Now, since I installed pygraphviz using the unofficial windows binary, which file can I modify to link both the library and include for graphviz's path? You would you usually find in the setup.py of pygraphviz the library and include paths when you don't use the unofficial binaries.
UPDATE 1
I added to PATH in Regedit under SOFTWARE a folder GRAPHIZ with a new key (default) with value C:\Program Files (x86)\Graphviz2.36\bin
UPDATE 2
I was having an error in the pydot.py file regarding the difficulty of Python locating the path of Graphviz. I made the changes as follow:
def _graphviz():
if os.sys.platform == 'win32':
path = r"C:/Program Files (x86)/Graphviz2.36/bin/"
progs = __find_executables(path)
return progs
find_graphviz()
{'fdp': 'C:/Program Files (x86)/Graphviz2.36/bin/fdp.exe', 'twopi': 'C:/Program Files (x86)/Graphviz2.36/bin/twopi.exe', 'neato': 'C:/Program Files (x86)/Graphviz2.36/bin/neato.exe', 'dot': 'C:/Program Files (x86)/Graphviz2.36/bin/dot.exe', 'circo': 'C:/Program Files (x86)/Graphviz2.36/bin/circo.exe'}
That seems ok with me but when I execute say:
positions = nx.graphviz_layout(G, prog='twopi', root=0)
I get:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Users\chamar.stu\AppData\Local\Continuum\Anaconda\lib\site-packages\networkx\drawing\nx_agraph.py", line 229, in graphviz_layout

raise ValueError("Program %s not found in path."%prog)
ValueError: Program twopi not found in path.
Why?

Here are the steps I followed to get pygraphviz working for Python 3.4 (I think if you follow the analogous steps, it should work for Python 2.x). I'm just documenting it here for future visitors to the page :
Pre-requisites :
wheel (Should be present by default in newer distributions)
The correct Windows build of pygraphviz (unofficial builds). On Win7 x64, I selected "pygraphviz‑$version-cp34‑none‑win_amd64.whl".
(Note the cp34 indicating the python version.)
The Graphviz installer version 2.38 (for which the above wheel is built)
Steps:
Run the Graphviz installer
Add the Graphviz\bin folder to your user or system PATH
Check: Open a command prompt and execute twopi -V. You should be able to see the Graphviz version printed onto the console.
Now go to your Python environment (e.g. by running anaconda.bat, a prompt where you can run python)
Run pip install pygraphviz‑*$version*-cp34‑none‑win_amd64.whl
You're done :) ! Run an example script to see if everything went well.

You'll find loads of install-ready packages on this site: http://www.lfd.uci.edu/~gohlke/pythonlibs/ including the ones you tried to install. I know I'm way too late with the answer but I just became a member.

You may first install "easy_install" (look at
How to use Python's "easy_install" on Windows ... it's not so easy)
then 2 packages are required: 'python-pygraph' & 'libgv-python'.
