Error: No module named 'pymem.process'; 'pymem' is not a package - python

I am trying to learn how to use pymem in Python.
I have tried to make two different programs according to two tutorials I have seen but I always get the same error when I try to run the code.
I have this:
from pymem import Pymem
pm = pymem("ac_client.exe")
health = pm.read_int(0x007B43F4)
print ("Health: ", health)
But when I try to run the code I get the following error:
Traceback (most recent call last):
File "c:\Users\N\Desktop\PYTHON\pymem\pymem2.py", line 1, in <module>
from pymem import Pymem
File "c:\Users\N\Desktop\PYTHON\pymem\pymem.py", line 4, in <module>
from pymem.process import *
ModuleNotFoundError: No module named 'pymem.process'; 'pymem' is not a package
I have pymem installed in it's latest version from Visual Studio Code. And in the videos I've seen (one is from a few months ago) they have the same code as me.

You have a file named pymem.py that's mentioned in the exception message (specifically c:\Users\N\Desktop\PYTHON\pymem\pymem.py). This locally written pymem module is shadowing the pymem package you've installed elsewhere (python\python310\lib\site-packages according to one of your comments, though that path is not complete).
You need to rename your pymem.py file to something else if you want to be able to use the package.

I think you don't have it installed, try going into cmd, Terminal or whatever and type pip install pymem.
pip should install the package for you and you should be good.

I cannot import libraries into python despite repeatedly installing them

I am struggling to install and import python libraries into my programs. originally I was using pydev but I kept getting messages like:
Traceback (most recent call last): File "C:\Users\satur\eclipse-workspace\DMD experimental\Main.py", line 11, in <module> from matplotlib import pyplot as plot ModuleNotFoundError: No module named 'matplotlib'
I installed matplotlib using py -m pip install matplotlib which produced a few messages like this.
WARNING: The script f2py.exe is installed in 'C:\Users\satur\AppData\Local\Programs\Python\Python310\Scripts' which is not on PATH. Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location. WARNING: The scripts fonttools.exe, pyftmerge.exe, pyftsubset.exe and ttx.exe are installed in 'C:\Users\satur\AppData \Local\Programs\Python\Python310\Scripts' which is not on PATH.
I was unsure what this meant so I tried running my program again and got the module not found error again.
being unable to resolve the issue I moved over to spyder because it came with many of the libraries I wanted thus avoiding the issue. however, as soon as I tried to import and install libraries not included with spyder I encountered the module not found error and a similar warning about the path. I added the paths mentioned in the warning to the PATH in spyder now when I run my code get this error message:
runfile('C:/Users/satur/.spyder-py3/proper orthogonal decomposition/dynamic mode decomposition experimental driver.py', wdir='C:/Users/satur/.spyder-py3/proper orthogonal decomposition')

I did some looking around and found this
https://github.com/spyder-ide/spyder/wiki/Working-with-packages-and-environments-in-Spyder#installing-packages-into-the-same-environment-as-spyder
I followed what instructions I understood
import sys; sys.executable
Out[50]: 'C:\\Users\\satur\\AppData\\Local\\Programs\\Spyder\\Python\\python.exe'
which is different from what I get when I run it in command prompt or in the pydev terminal both of which give me
C:\Users\satur\AppData\Local\Microsoft\WindowsApps\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0\python.exe
when i go to C:\Users\satur\AppData\Local\Microsoft\WindowsApps\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0\ I see: 3 versions of idel, 3 versions of pip, and 6 versions of python.
I am deeply confused. I want to install and import libraries into my python programs. I want to be able to run my programs in either (or for that matter any) ide. I seem to be hitting the very similar issues in both. every tutorial I have found online describes the steps to take to do this but not what they are or why I am doing them none of them seem to work and the more times I try to install things the more confused I get.
could someone please explain: how to install and import libraries into a python program. what python is doing when I install things and try to import them. and why both IDEs have similar but different errors.

Script works in Anaconda Prompt but not via Command Line

I am unable to run a python script in the command line, and this script works great in Jupyter Notebook and via Anaconda Prompt. This appears to be an issue importing the ssl module during initialization of another module I am importing (mygeotab).
I have googled the error and done as much as I can to diagnose the most common cause which appears to be PATH issues.
I have already diagnosed the PATH to a point, and have added the location of the /lib/ and python.exe to the environment variables. Also, during testing I began my script with the below to protect myself from path issues and printed the path before and after the 'append', which did not have an impact on the problem.
import sys
print(sys.path)
sys.path.append('C:\\Users\\xxxxxx\\Python Scripts')
sys.path.append('C:\\Anaconda3\\python37.zip')
sys.path.append('C:\\Anaconda3\\DLLs')
sys.path.append('C:\\Anaconda3\\lib')
sys.path.append('C:\\Anaconda3')
sys.path.append('C:\\Anaconda3\\lib\\site-packages')
sys.path.append('C:\\Anaconda3\\lib\\site-packages\\win32')
sys.path.append('C:\\Anaconda3\\lib\\site-packages\\win32\\lib')
sys.path.append('C:\\Anaconda3\\lib\\site-packages\\Pythonwin')
sys.path.append('C:\\Anaconda3\\lib\\site-packages\\IPython\\extensions')
sys.path.append('C:\\Users\\xxxxxx\\.ipython')
sys.path.append('C:\\Anaconda3\\Lib')
sys.path.append('C:\\Anaconda3\\Lib\\site-packages')
print(sys.path)
import mygeotab
import pandas as pd
import pyodbc as py
from mygeotab.ext import feed
import sqlalchemy
from time import sleep
However, when I attempt to run the script via the standard command line, I get the below error:
Traceback (most recent call last):
File "PYTHON_GEOTAB_TRIP_FEED.py", line 33, in <module>
import mygeotab
File "C:\Anaconda3\lib\site-packages\mygeotab\__init__.py", line 9, in <module>
from .api import Credentials
File "C:\Anaconda3\lib\site-packages\mygeotab\api.py", line 14, in <module>
import ssl
File "C:\Anaconda3\lib\ssl.py", line 98, in <module>
import _ssl # if we can't import it, let the error propagate
ImportError: DLL load failed: The specified module could not be found.
The mygeotab module and ssl.py are both in the locations designated in the Traceback. '_ssl' is the only reference I can not seem to diagnose. Again, this works fine in both Notebook and Anaconda Prompt.
Any ideas?
Windows Server 2008 R2
Anaconda 2019.07 x64
Python 3.7.3 x64
This was solved for me by installing a separate instance of Python 3.7, moving the PATH references and other pointers. I installed pip, mygeotab, and the other packages into the native Python 3.7 instance. It just appears you can't use the one baked into anaconda the way I thought. Thanks for the help everyone.

Python module sqlite3 cannot be found, but is listed [duplicate]

I would like to have an interface between Python and sqlite. Both are installed on the machine. I had an old version of Python (2.4.3). So, pysqlite was not included by default. First, I tried to solve this problem by installing pysqlite but I did not succeed in this direction. My second attempt to solve the problem was to install a new version of Python. I do not have the root permissions on the machine. So, I installed it locally. The new version of Python is (2.6.2). As far as I know this version should contain pysqlite by default (and now it is called "sqlite3", not "pysqlite2", as before).
However, if I type:
from sqlite3 import *
I get:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/verrtex/opt/lib/python2.6/sqlite3/__init__.py", line 24, in <module>
from dbapi2 import *
File "/home/verrtex/opt/lib/python2.6/sqlite3/dbapi2.py", line 27, in <module>
from _sqlite3 import *
ImportError: No module named _sqlite3
It has to be noted, that the above error message is different from those which I get if I type "from blablabla import *":
Traceback (most recent call last):
File "", line 1, in
ImportError: No module named blablabla
So, python see something related with pysqlite but still has some problems. Can anybody help me, pleas, with that issue?
P.S.
I use CentOS release 5.3 (Final).
On Windows, _sqlite3.pyd resides in C:\Python26\DLLs. On *nix, it should be under a path similar to /usr/lib/python2.6/lib-dynload/_sqlite3.so. Chances are that either you are missing that shared library or your PYTHONPATH is set up incorrectly.
Since you said you did not install as a superuser, it's probably a malformed path; you can manually have Python search a path for _sqlite3.so by doing
import sys
sys.path.append("/path/to/my/libs")
but the preferred approach would probably be to change PYTHONPATH in your .bashrc or other login file.
You have a "slite3.py" (actually its equivalent for a package, sqlite3/__init__.py, so import sqlite3 per se is fine, BUT that module in turns tries to import _sqlite3 and fails, so it's not finding _sqlite3.so. It should be in python2.6/lib-dynload under your local Python root, AND ld should be instructed that it has permission to load dynamic libraries from that directory as well (typically by setting appropriate environment variables e.g. in your .bashrc). Do you have that lib-dynload directory? What's in it? What environment variables do you have which contain the string LD (uppercase), i.e. env|grep LD at your shell prompt?

Importerror with Python Buffer Library

I downloaded this library: https://github.com/bufferapp/buffer-python
Ran the setup.py install, and then tried to run some code using the newly installed library.
What happens though is I get this error:
Traceback (most recent call last):
File "twitter-quote-bot.py", line 14, in <module>
from buffpy.managers.profiles import Profiles
ImportError: No module named managers.profiles
The only way I've found to fix it is to move my program (twitter-quote-bot) into the downloaded folder from Buffer and run it there.
Did I do something wrong in the installation? It seems like I should be able to do these imports globally.
Thanks in advance!
