I recently ran pip install pyodbc. Which says it installed pyodbc successfully on the cmd.
However when I do import pyodbc in IDLE I receive an error saying 'No module named pyodbc'.
It seems only two files have been installed when I ran pip install pyodbc.
The two files:
pyodbc-4.0.26.dist-info
pyodbc.cp36-win32.pyd
VERSION of Python:
Python 3.6.3
Complete Error Message:
Error Message
How do I resolve this issue? Any help would be much appreciated, I'm new to python and this is quite frustrating.
The files that installed are fine. *.pyd is compiled library (see https://docs.python.org/3/faq/windows.html#is-a-pyd-file-the-same-as-a-dll).
Issues that may cause this:
IDLE running main python installation and you installed the package in virtual environment
You have several installations of python e.g. python 3.x alongside python 2.x
I think first of all try to run all the steps from the same cmd:
PS C:\Windows\system32> pip install pyodbc

This should work...
And then try to understand if you have several virtualenvs or python instalations.
You can check which python IDLE run, by right click on it's shortcut and "open file location" for example

Due to external dependencies I need to run python 3.6.x (I know it is EOL) on Windows.
However, any external library causes the interpreter to just silently quit.
As an example I have installed numpy in the following way
py -m pip install numpy
And then running Python through PowerShell:
PS C:\Users\USER> py
Python 3.6.8 (tags/v3.6.8:3c6b436a57, Dec 24 2018, 00:16:47) [MSC v.1916 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
PS C:\Users\USER>
As soon as I run import numpy the python interpreter simply silently returns.
I have tried to install every python 3.6.x available from Pythons official website, and the issue persists.
I fully removed old versions of python between each install.
I cannot find any error logs or anything.
What can be the issue here and how can I debug further?
Any internal library (that I have tried) works
I have tried with the following libraries:
Numpy
Tensorflow
Protobuf
matplotlib
scipy
pandas
nose
sympy
When I try to install my library locally and test it, it shows up as installed:
PS C:\Projects\pypi\potatoutils> pip install -e .

>>> import potatoutils
I get this error:

File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'potatoutils'
What am I doing wrong?
EDIT: pip and python have the same version (3.7) and their paths match.
And the library shows up when I use pip list.
Often this is the issue if you pip install a package with pip for python2.x
but then when you attempt to import your library for python3.x
Make sure you're running installing pip packages for the correct python version.
use pip3 using pip sometimes point to python 2.x versions, that's why maybe it can help!
Okay, so I managed to get the library up and running by starting over and following these instructions:
https://medium.com/analytics-vidhya/how-to-create-a-python-library-7d5aea80cc3f
I still don't know what went wrong the first time (maybe outdated instructions?) but it no longer matters to me.
I just started having some problems with python, and would like to fix this the proper way, as a last resort, reinstalling if I have to.
Before Python 3, I had Python 2.7 installed. I then installed Python 3.7 along side it. I don't remember, if the path environment was automatically set, or if i manually set it.
My system variables path contains :
C:\Python27\;C:\Python27\Scripts;
So I believe this was set automatically.
My user variables path however contains :
C:\Python37\;C:\Python37\Scripts;
Would the python installer use the user environment? I'm not sure, so I don't know if I set that myself.
However, the user variables path also contains :
%PYTHON_DIR%\Python37\Scripts\;%PYTHON_DIR%\Python37\;%PYTHON_DIR%\Python36\Scripts\;%PYTHON_DIR%\Python36\
Again, I don't know if I set this myself, and I have no recollection of setting this in my user variables :
PYTHON_DIR = C:\Users\pcuser\AppData\Local\Programs\Python
...but it's there, and I have two folders in that path.
I also have this in my user variables path :
PYTHON = os.path.expanduser(os.getenv('PYTHON', 'C:\\Python37\\python.exe'))
I know I created a python environment. I just have to look for it, as I don't remember where to find it right now.
Here is the problem I am having.
I also am using Python in MSYS, and get this error from Python in C:\msys64\usr\bin :
Could not find platform independent libraries <prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
Fatal Python error: initfsencoding: Unable to get the locale encoding
ModuleNotFoundError: No module named 'encodings'
Current thread 0x0000000800018040 (most recent call first):
0 [main] python 1489 cygwin_exception::open_stackdumpfile: Dumping stack t
race to python.exe.stackdump
I set PYTHONHOME to C:\msys64\usr\bin. That doesn't solve the problem.
I also removed PYTHON_DIR to see if there was a conflict there, but that didn't solve the problem.
Rather, I got another error :
Fatal Python error: initfsencoding: Unable to get the locale encoding
ModuleNotFoundError: No module named 'encodings'
Current thread 0x0000000800018040 (most recent call first):
0 [main] python 143 cygwin_exception::open_stackdumpfile: Dumping stack tr
ace to python.exe.stackdump
So it seems to me my Python environment is messed up, and I want to learn how to set it up correctly, hopefully without having to start over.
How can I get rid of these errors, and get a proper python environment?
Personally, I use miniconda.
Miniconda is the small version of anaconda which is an excellent environment manager. Miniconda does not include a gui and I feel it is nicer to work with.
To create an environment with
conda create -n my-test-env python=3.9
You can activate it using
conda activate my-test-env
You can install other packages using
conda install numpy.
However, not all python packages are available in conda. You can any pip packages by installing pip
conda install pip
pip install numpy
Setting PYTHONHOME to a value like C:\msys64\usr\bin is definitely wrong; it should be something like C:\Python37\Lib if that's where Python installed its libraries. But try simply unsetting it.
After a while of troubleshooting, I was able to discover where the problem was.
Some files in C:\msys64\usr\lib\python3.8 somehow got deleted, or python 3.8 was installed, but not properly. So I did a reinstall, and python stopped complaining about missing encodings and modules.

My python environment is good. All working nicely. :)
What I learned...
Using PYTHONHOME and PYTHONPATH is not neccesary, as was suggested by many... although equally suggessted by many.
From my experience - speaking fron a novice perspective - I would not recommend using them.
Maybe they work for others, but I got errors regardless of how I set it up - whether
C:\Python37 or
C:\Python37\lib or
C:\Users\pcUser\AppData\Local\Programs\Python\Python37 or
C:\msys64\usr\lib\python3.8;C:\msys64\usr\lib\python3.8\site-packages;C:\msys64\usr\lib\python3.8\lib-dynload;C:\msys64\usr\lib\python3.8\distutils
They all return a heap of errors on one installment or other.
So it does not work for me. However, probably works for others.
I am happy though that after probably more than 60 hours, my python environment is back in working order. :)
I have installed python 2.7 and also I have requests package installed. I am not sure of the reason, the site-packages are in a different location and my python 2.7 core files are in a different location
C:\Program Files\Python27
C:\Users\MyID\AppData\Roaming\Python\Python27\site-packages
I can see requests and the binaries in the path C:\Users\MyID\AppData\Roaming\Python\Python27\site-packages\requests. Yet when my job runs, it throws an error as shown below.
File "C:\Program Files (x86)\Jenkins\workspace\code\xxxx.py", line 36, in <module>
import requests
ImportError: No module named requests
I have only one version of python installed.

This is most probably the problem of virtual environment, virtual environment (venv) isolate your work environment in such a way that you can have different workspace for same version of python, that's why you are getting the error, I suspect that you installed request module in original python, but trying to run the script in virtual environment, hence it's giving error
Here, try these steps and tell the result
Open CMD
Write cd C:\Users\MyID\Desktop\xxx\Automation\xxxxxx\venv\Scripts , Press enter.
Write python -m pip install requests
Wait for it and tell the result, this must fix your problem
For reference on virtual environment and pip, look at this.
I want to start with I am new to the python language and am learning on my own. My issue is that I am installing the modules that I'm trying to use. The installs are successful but do not exist when I try to import them. I am using Visual Studio Code, Python 3.6, and Anaconda on Windows 10.
I am trying to use pyttsx3, SpeechRecognition and pocketsphinx.
$pip list
This gives me a very large list but does not contain either of my installed modules.
$python -m pip list
Gives me smaller output with them.

I am fine with this being something small on my part due to my lack of knowledge with this language, but I have done a full days worth of research trying to solve this myself.
Edit:
$pip --version
pip 9.0.1 from C:\Users\Keiro\Anaconda3\lib\site-packages (python 3.6)
You have two versions of pip perhaps two different installations of python as well. One with Anaconda and other one by main site.
Stick to one version and if you install in that use that environment in Visual Studio(Or VS Code)
You have installed those in anaconda which the standard installtion of Python wont recognize..
Open Python prompt from Anaconda Navigator >> Choose the environment (Select base for default) >> Open with Terminal [Or Open with Python]
>>python
>>import pyttsx3
In Visual Studio code set the same environment
Ctrl+Shift+P >> Select Python interpreter
Choose the anaconda location.
Volla. Now it should work
I had the same problem and found the answer in an old forum.
Write "pip3" instead of "pip".
So the code is:
pip3 install pyttsx3
(Source: bash: pip: command not found)
