ModuleNotFoundError: No module named. Problem with finding module

I'm struggling with using one of the python scripts I've written. I know there have been a couple similar questions to this one already, however I have tried pretty much everything I could find, and nothing works...
When I try to run a test program I get met with
ModuleNotFoundError: No module named 'v6-average-py'
I'll explain better throughout this post.
My file structure is this:
mean_package
|-README.md
|-setup.py
|-algorithm_pkg
|-__init__.py
Setup.py:
from os import path
from codecs import open
from setuptools import setup, find_packages
setup(
name='v6-average-py',
version="1.0.0",
description='v6 average',
long_description="description",
long_description_content_type='text/markdown',
url='https://github.com/IKNL/v6-average-py',
packages=find_packages(),
python_requires='>=3.6',
install_requires=[
'vantage6-client',
]
)
init.py is just two defined methods.
Then I run
pip install -e .
Which gives a bunch of requirement statisfied and
Running setup.py develop for v6-average-py
Successfully installed v6-average-py-1.0.0
And finally when it try to run a program I called testscript.py it fails at the first part with
client = ClientMockProtocol(
datasets=[".\\MOCK_DATA.csv", ".\\MOCK_DATA1.csv"],
module="v6-average-py"
)
It fails at
module="v6-average-py"
because the module can't be found I assume.
From what I have seen from similar questions it's either a problem with using different python versions, which I don't think is the issue here (running everything using pyenv, python 3.7.9 so it's all being run/installed with that).
I have also tried solutions where the problem has been find_packages() or the init.py file with no luck.
Maybe it's being put somewhere it can't be found?
Any input would be greatly appreciated

How to create setup.py with library file as stand alone

I have a problem, i develop an application with python and i use some libraries like flask, sqlalchemy, etc...
The problem is that i have a define version of each library, and I want to deploy this python application in another computer without internet,
can I create a package or use setup.py and include the other package with path ?
I've already try this code, but the library aren't imported they said that :
ModuleNotFoundError: No module named 'cx_Oracle'
My code is:
from distutils.core import setup
setup(
# Application name:
name="MyApplication",
# Version number (initial):
version="0.1.0",
# Packages
packages=["App","App/service"],
include_package_data=True,
install_requires=[
"flask","cx_Oracle","pandas","sqlalchemy"
],
)

install_requires is a setuptools setup.py keyword that should be used to specify what a project minimally needs to run correctly.
It won’t install those libraries.
Maybe you should try pyinstaller (https://www.pyinstaller.org) to make ready runnable file to run on the other computer.

Importing matplotlib.pyplot and BeautifulSoup with cxFreeze

I am attempting to compile an executable for my python script using cxFreeze. Out of the many libraries which I need to import for my script, two seem to fail with cxFreeze. In particular, consider the following test.py script:
print('matplotlib.pyplot')
import matplotlib.pyplot
compiling this with cxFreeze and running gives the following output:
separately, the following test.py script:
print('BeautifulSoup from bs4')
from bs4 import BeautifulSoup
after being compiled with cxFreeze, produces the following output:
My setup.py file for cxFreeze looks as follows:
import sys
from cx_Freeze import setup, Executable
setup(
name = "myname",
version = "1.0",
description = "some description",
executables = [Executable("test.py", base = None)]
)
I am running Python 3.3 x86, and am using a 32 bit version of cxFreeze (most recent) on Windows 7.
I am having trouble chasing down this issue. For one, the directory "C:\Python\32-bit..." doesn't exist on my computer, so I am unclear as to why cxFreeze is trying to look there. Does anyone have any idea how to approach this, or perhaps has already dealt with this issue?

After some digging around, I was able to resolve the issue. For those who may be encountering the same issue, this is what solved it for me:
For the issue with matplotlib: I simply needed to explicitly specify to cxFreeze to include matplotlib.backends.backend_tkagg. My setup file ended up looking like this:
import sys
from cx_Freeze import setup, Executable
packages = ['matplotlib.backends.backend_tkagg']
setup(
name = "myname",
version = "1.0",
description = "some description",
options = {'build_exe': {'packages':packages}},
executables = [Executable("test.py", base = None)]
)
As for the BeautifulSoup issue: There are a couple of posts around the web that have dealt with this issue: cx_freeze sre_constants.error nothing to repeat, https://bitbucket.org/anthony_tuininga/cx_freeze/issue/59/sre_constantserror-nothing-to-repeat.
The relevant conclusion: something is wrong with the 4.3.2 build of cxFreeze that causes this issue. I simply used cxFreeze 4.3.1 to build my app and the problem was solved. It may also be possible to rebuild 4.3.2 locally and have the issue be resolved, but I did not attempt this solution.

py2app ImportError with watchdog

I am attempting to use py2app to bundle a small Python app that I've made in Python 2.7 on Mac. My app uses the Watchdog library, which is imported at the top of my main file:
from watchdog.observers import Observer
from watchdog.events import FileSystemEventHandler
When running my program, these import statements work just fine, and the program works as expected. However, after running py2app, launching the bundled application generates the following error:
ImportError: No module named watchdog.observers
At first I thought it was something to do with the observers module being nested inside watchdog, but to test that, I added the line
import watchdog
to the top of my program, and then upon running the app, got the error
ImportError: No module named watchdog
so it seems that it actually can't find the watchdog package, for some reason.
I tried manually adding the watchdog package using py2app's --packages option:
$ python setup.py py2app --packages watchdog
but it had no effect.
My unbundled Python program runs just fine from the command line; other downloaded modules I've imported are giving no errors; and I have successfully bundled a simple "Hello World!" app using py2app, so I believe my setup is correct.
But I'm kind of out of ideas for how to get py2app to find the watchdog package. Any ideas or help would be greatly appreciated.
Edit: Here is the text of my setup.py, as generated by py2applet. I haven't modified it.
from setuptools import setup
APP = ['watcher.py']
DATA_FILES = []
OPTIONS = {'argv_emulation': True}
setup(
app=APP,
data_files=DATA_FILES,
options={'py2app': OPTIONS},
setup_requires=['py2app'],
)

Try manually including the desired packages in the setup.py file:
from setuptools import setup
APP = ['watcher.py']
DATA_FILES = []
PKGS = ['watchdog', /*whatever other packages you want to include*/]
OPTIONS = {
'argv_emulation': True,
'packages' : PKGS,
}
setup(
app=APP,
data_files=DATA_FILES,
options={'py2app': OPTIONS},
setup_requires=['py2app'],
)

I had installed watchdog 0.5.4, a very old version as it turns out, and got the same error. The error was fixed after upgrading it to 0.8.3:
pip install watchdog --upgrade

Your problem generally indicates that the package (in your case "watchdog", or one of its dependencies) isn't installed, or at least not in a location that py2app expects to find packages.
Do you use the same python command for running py2app as for running the script from the command-line? What is the message of the ImportError you're getting (both when importing "watchdog" and importing "watchdog.observers"?
The (way too long) output of py2app should also mention that it cannot find some packages, and which ones.

As alluded to in one of the answers py2app does not seem to search the same set of paths that are used by the python interpreter, so you need to copy the python library to one of those locations.
For example I've got the MacPorts version of Python installed and found that when I had a module installed in /Library/Python/2.7/site-packages/ py2app wasn't finding it, but it would find it when I copied it into /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages. So to copy it over run :
sudo cp /Library/Python/2.7/site-packages/thatmodule.so /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/
Then run the py2applet script again and build the app to check. If it's elsewhere you can do a search for all site-packages locations using Spotlight's command line interface:
mdfind -name site-packages

How to package Twisted program with py2exe?

I tried to package a Twisted program with py2exe, but once I run the exe file I built, I got a "No module named resource" error.
And I found the py2exe said:
The following modules appear to be missing ['FCNTL', 'OpenSSL', 'email.Generator', 'email.Iterators', 'email.Utils', 'pkg_resources', 'pywintypes', 'resource', 'win32api', 'win32con', 'win32event', 'win32file', 'win32pipe', 'win32process', 'win32security']
So how do I solve this problem?
Thanks.

I've seen this before... py2exe, for some reason, is not detecting that these modules are needed inside the ZIP archive and is leaving them out.
You can explicitly specify modules to include on the py2exe command line:
python setup.py py2exe -p win32com -i twisted.web.resource
Something like that. Read up on the options and experiment.

Had same issue with email module. I got it working by explicitly including modules in setup.py:
OLD setup.py:
setup(console = ['main.py'])
New setup.py:
setup(console = ['main.py'],
options={"py2exe":{"includes":["email.mime.multipart","email.mime.text"]}})
