Python: Can't find file even though file referenced exists

I'm getting this error when trying to run a Python script. Is it saying that it can't find subprocess.py? Because I found it in the location it's listing there, so I doubt that's the issue. What file can't it find?
Traceback (most recent call last):

You may need to put the full path in the run(...) command, to the open file, and the path to the .mp4 file as well.
Most likely, open does not exist on your system and you have to use the name of the video player software instead.

Make sure the user you're running the script as has read permission for the file.

You may also try with subprocess.Popen(args, shell=True). The use of shell=True may be useful.
Also, use a path defined as path = os.path.join(filepath, filename) and then before passing the path to Popen, assert if os.path.exists(path)==True.
But note that there are some downsides to using shell=True:

I am using a python package from Gray Arrow's Dejavu. I have installed all the required dependencies and other packages necessary to run my code. When running the following code:
import warnings
import json
warnings.filterwarnings("ignore")
from dejavu import Dejavu
from dejavu.recognize import FileRecognizer
with open('dejavu.cnf') as f:
config = json.load(f)
djv = Dejavu(config)
djv.fingerprint_file('mp3/Sean-Fournier--Falling-For-You.mp3')
song = djv.recognize(FileRecognizer, 'mp3/Sean-Fournier--Falling-For-
You.mp3')
print("from file recognized: {}\n".format(song))
I receive the following errors:

I have done complete re-installations of python 3.7 and all of the packages and dependencies to attempt correction of this problem.
I do not understand what file cannot be found and have done research in hopes to find an answer to this issue. I truly appreciate any help and knowledge that can be shared with me on this topic.

Try and place "Sean-Fournier--Falling-For-You.mp3" file in the exact directory you have your script, I don't think the folder reference to the mp3 folder is being handled correctly :)
djv.fingerprint_file('mp3/Sean-Fournier--Falling-For-You.mp3')
song = djv.recognize(FileRecognizer, 'mp3/Sean-Fournier--Falling-For-
You.mp3')

Simple HTML to PDF python library error

I'm using this pydf to convert HTML to a PDF on our server. This is an example that comes right from their docs that illustrates the problem:
import pydf
pdf = pydf.generate_pdf('<h1>this is html</h1>')
with open('test_doc.pdf', 'wb') as f:
f.write(pdf)
When I go to run this file, I get the same error everytime:
(pdf) <computer>:<folder> <user>$ python pdf.py
Traceback (most recent call last):
File "pdf.py", line 3, in <module>
pdf = pydf.generate_pdf('<h1>this is html</h1>')

errread, errwrite)

raise child_exception
I'm running this in a virtualenv and my pip freeze is only the following:
python-pdf==0.30
Any idea what could be going wrong here?

As you are using macOS, you need to download a wkhtmltopdf binary by your own:
pydf comes bundled with a wkhtmltopdf binary which will only work on Linux amd64 architectures. If you're on another OS or architecture your milage may vary, it is likely that you'll need to supply your own wkhtmltopdf binary and point pydf towards it by setting the WKHTMLTOPDF_PATH variable.

FileNotFoundError on python

img = printscreen_pil
img = img.filter(ImageFilter.MedianFilter())
enhancer = ImageEnhance.Contrast(img)
img = enhancer.enhance(2)
img = img.convert('1')
img.save('temp.jpg')
text = pytesseract.image_to_string(Image.open('temp.jpg'))
I want to read the image in order to convert it to text but i get the error system cannot find the file specified. I think it has to do with the working directory of the python. I'm sorry if this is a stupid question but I hope you can help me.
this is the complete error mssg.

The tesseract package does not seem to be installed on your system, or it is not found on your path. pytesseract runs the tesseract binary as a sub process in order to perform the OCR.
Use the package manager on your OS to install it, or refer the the installation documentation. You are using Windows so check this out.
Also I don't think that it is necessary to write the enhanced image to file first, just pass it directly to pytesseract.image_to_string:
text = pytesseract.image_to_string(img)

Error in opening image file in PIL

I am trying to execute the following code

print i
im = Image.open(i.strip())
text = image_to_string(im)

I get the following error

Can someone please explain what I am doing wrong here.
Renamed the image file.Shifted the python file and the images to a new folder. Shifted the folder to E drive
Now the code is as follows:
from pytesser import *
import Image
import os
i=os.path.join("E:\\","ocr","a.jpg")
print i
im = Image.open(i.strip())
text = image_to_string(im)
print text
Now the error is as follows:

You need to install Tesseract first. Just installing pytesseract is not enough. Then edit the tesseract_cmd variable in pytesseract.py to point the the tessseract binary. For example, in my installation I set it to
tesseract_cmd = 'C:\\Program Files (x86)\\Tesseract-OCR\\tesseract.exe'

The exception is pretty clear: the file either doesn't exist, or you lack sufficient permissions to access it. If neither is the case, please provide evidence (e.g. relevant dir commands with output, run as the same user).

your image path maybe?
i="C:\\Documents and Settings\\Administrator\\Desktop\\attachments\\R1PNDTCB.jpg"
try this:
import os
os.path.join("C:\\", "Documents and Settings", "Administrator")
you should get a string similar to the one in the previous line

Try this first:
os.path.expanduser('~/Desktop/attachments/R1PNDTCB.jpg')
It could be that the space in the 'Documents and Settings' is causing this problem.
EDIT:
Use os.path.join so it uses the correct directory separator.

Just add these two lines in your code
import OS
os.chdir('C:\Python27\Lib\site-packages\pytesser')
before
from pytesser import *

If you are using pytesseract, you have to make sure that you have installed Tesseract-OCR in your system. After that you have to insert the path of the tesseract in your code, as below
from PIL import Image
import pytesseract
pytesseract.pytesseract.tesseract_cmd = 'C:/Program Files (x86)/Tesseract
OCR/tesseract'
You can download the Tesseract-OCR form https://github.com/UB-Mannheim/tesseract/wiki
