ImageIO ValueError in exe made by pyinstaller

I made an exe to read images including gifs using pyinstaller. However, the exe can't read gif and the below error occurs. I have installed the latest version of imageio and the program works in interpreter. Could you advise? Thanks in advance.
The line raising error:
cv_gif = imageio.mimread(pic_path)
Error:
Traceback (most recent call last):
File "Image Viewer.py", line 3085, in <module>
File "Image Viewer.py", line 522, in go
File "Image Viewer.py", line 1264, in ShowANI
File "imageio\core\functions.py", line 247, in mimread
File "imageio\core\imopen.py", line 277, in imopen
ValueError: Could not find a backend to open `C:\Users\simon\Practice\testdir3\alpaca.gif`` with iomode `rI`.
Based on the extension, the following plugins might add capable backends:
pillow: pip install imageio[pillow]
GIF-PIL: pip install imageio[pillow]

I have exactly the same problem.
This might have something to do with the new feature of imageio introduced in version 2.11.0: Choose plugin based on extension and plugin lazy-import. Revert back to 2.10.5 solves the problem.

Just manually copied the folder \Lib\site-packages\imageio and replaced the imagoio folder of the exe, then it works.

Py to exe pyinstaller import errors

Im trying to convert a single file python script/project into an exe using pyinstaller
Even thought pyinstaller converts the script the .exe will run and throw this
Traceback (most recent call last):
File "main.py", line 4, in <module>
File "PyInstaller\loader\pyimod03_importers.py", line 540, in exec_module
File "pynput\__init__.py", line 40, in <module>

File "pynput\keyboard\__init__.py", line 31, in <module>
File "pynput\_util\__init__.py", line 76, in backend
ImportError
[16676] Failed to execute script main
I'm stumped , through my trial and erroring i figured that when i replace pynput with a module like random the convertion works fine , but i need it to work with pynput
please help , thanks in advance!

Authors made some changes which i feel broke the reference.
so instead of package it is referring file.
- backend = backend(__package__)
+ backend = backend(__name__)
pls try to downgrade your package and check that your app still works.
pip install pynput==1.6.8
then your command like following would work.
pyinstaller --onefile build_pkg_for.py

PyDub OSError: [WinError 6] The handle is invalid

I'm having a similar issue on Python 3.8.7, and I can't find the solution.
In my project, I'm using pydub.AudioSegment to get audio from a file and then exporting that audio in a different format. My code works perfectly when I'm running the python file directly. However, when I convert it to an executable with pyinstaller, run the program and get to the point of importing the audio with pydub, it gives me the following error:
Traceback (most recent call last):
File "main.py", line 269, in <module>
File "main.py", line 213, in convertfile
File "main.py", line 133, in cloud_upload

File "subprocess.py", line 804, in __init__
File "subprocess.py", line 1142, in _get_handles
OSError: [WinError 6] The handle is invalid
pydub call in my program looks like this:
sound = AudioSegment.from_file(filepath)
sound.export(new_filepath, format="ogg",codec='libopus')
I've tried to add stdin=subprocess.DEVNULL and stdin=subprocess.PIPE in utils.py on line 274, but that didn't work either. Maybe I added them incorrectly, though, so suggestions like that are also highly appreciated.

I've managed to solve the problem only by removing --onefile option from pyinstaller and dropping ffmpeg.exe and ffprobe.exe into the resulted folder with the main.exe file.
That's not a good solution to the problem as I'd still prefer to use --onefile; but it works.
I'm still open to suggestions on how to make it work with --onefile or just generally why this is hapenning.

Chances are is that PyInstaller cannot recognize the imported plugin. Although if you are trying to make a app, I suggest using a shortcut instead, it is better due to the fact that you can customize the icon for the shortcut. It is what many apps mainly use.

Can't run python script converted to exe

I have created a python program that sends data to google spreadsheets using the following external libaries:
json
gspread
oauth2client
The program works as expected, however when I tried to convert it to an executable, I would get the following error every time I rune the .exe file:
Traceback (most recent call last):
File "C:\Python27\lib\site-packages\cx_Freeze\initscripts\Console.py", line 27, in <module>
exec(code, m.__dict__)

File "C:\Python27\lib\site-packages\oauth2client\client.py", line 1581, in _RequireCryptoOrDie
raise CryptoUnavailableError('No crypto library available')
oauth2client.client.CryptoUnavailableError: No crypto library available
Would any of you guys know what the problem could be, and what steps I could take to solve it?
Thanks in advance
Edit: I tried to use both cx_freeze and py2exe. I got similar errors in both
Below is the setup.py I used in cx_freeze:
from cx_Freeze import setup, Executable
setup(name = "Demo" ,
version = "1.0" ,
description = "A python Demo" ,
executables = [Executable("Demo.py")])

I have been getting above error. Could some one please tell me how would i fix it?

The problem seems to be related to this github issue, essentially the skimage.io._plugins submodule is making life hard for Pyinstaller.
To make sure everything you need is packaged you should have a hook file that contains
from PyInstaller.utils.hooks import collect_data_files, collect_submodules
datas = collect_data_files("skimage.io._plugins")
hiddenimports = collect_submodules('skimage.io._plugins')
(or if you already have a hook file with these, extend the current datas and hiddenimports).
