"ModuleNotFoundError: No module named 'spacy'" even though I installed it via pip [duplicate]

I am trying to import pyodbc module on a windows computer. It works in the terminal, but not the IDLE. The error message in IDLE is:
Traceback (most recent call last):
File "FilePath/Filename.py", line 3, in <module>
import pyodbc
ImportError: No module named pyodbc

This typically occurs when multiple versions of python are installed with different paths. You can check to see if you have multiple installations by opening up the IDLE terminal and using
import sys
sys.version
sys.path
These commands will print the system PATH and version of the current instance of python. Use this in both IDLE and the command line terminal to see where each differ. Once you know which version is the one you want then just remove the other. You could also remove all python instances and then reinstall a clean python environment but then you would have to re-install all of your modules using pip or easy_install

Open python in cmd (type python and press enter)
Import the module in cmd (type import modulename)
Type modulename.__file__
You will get the path where the module is stored
Copy the corresponding folder
In IDLE, import sys and typing sys.executable to get the paths where it looks for modules to import
Paste your module's folder in the path where IDLE looks for modules.
This method worked for me.

You can pip show after install package and know about location where package installed.
After that check in IDLE sys.path and if directory with package not in sys.path try to add it.
import sys
sys.path.append("/home/dm/.local/lib/python3.6/site-packages")
# or another folder that `pip show` about package.

this happen because of multiple python installed (32bit version, 64bit version) or 3v and 2.7v so to solve this problem you have to invoke the idle for that specific version like this
cd to the dir of the version that the import work fine in cmd in that folder type this command below
pythonw.exe Lib\idlelib\idle.pyw
this command will invoke idle for that version
and the import will work fine

Me too had the same issue while trying to import a module which was successfully imported on terminal and not able to install on IDLE.
How I fixed?
Assuming you know how to execute commands on terminal as well as inside of python interpreter
Open your Terminal & execute the below commands :
:~$ python3
Python 3.6.9 (default, Jan 26 2021, 15:33:00)
[GCC 8.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>
>>>
>>> import sys
>>> sys.version
'3.6.9 (default, Jan 26 2021, 15:33:00) \n[GCC 8.4.0]'
>>> sys.path
['', '/usr/lib/python36.zip', '/usr/lib/python3.6',
'/usr/lib/python3.6/lib-dynload', '/usr/local/lib/python3.6/dist-
packages', '/usr/lib/python3/dist-packages']
>>>
Now import your module inside of your python3 interpreter.
>>> import nester
>>>
>>> nester.__file__
'/usr/local/lib/python3.6/dist-packages/nester.py'
>>>
Open your IDLE and run the below commands and compare them
Python 3.9.1 (tags/v3.9.1:1e5d33e, Dec 7 2020, 17:08:21) [MSC v.1927

>>> import sys
>>> sys.version

>>> sys.path
['','C:\Users\username\AppData\Local\Programs\Python\Python39\Lib\idlelib', 'C:\Users\username\AppData\Local\Programs\Python\Python39\python39.zip', 'C:\Users\username\AppData\Local\Programs\Python\Python39\DLLs', 'C:\Users\username\AppData\Local\Programs\Python\Python39\lib', 'C:\Users\username\AppData\Local\Programs\Python\Python39', 'C:\Users\username\AppData\Local\Programs\Python\Python39\lib\site-packages']
>>> sys.executable
'C:\Users\username\AppData\Local\Programs\Python\Python39\pythonw.exe'
Now if you compare both outputs from Terminal & IDLE,
Terminal Module location is different from IDLE
I was using Ubuntu 18 terminal on windows machine
So I just copied my file to 'C' directory and ensured its file privileges. That's it.
:~$ cp -p /usr/local/lib/python3.6/dist-packages/nester.py /mnt/c/Users/username/AppData/Local/Programs/Python/Python39/Lib/
It worked!!

I Found the solution. It works for me
The problem is your installation directory does not match with the python version directory.
solution is >>>
type %localappdata% in your search bar then go to this folder.
here select the program folder. then select Programs , Python , Python version , Scripts
copy the location of the Scripts folder
open command prompt and type cd //yourpath (in my case cd C:\Users\3C HOUSE\AppData\Local\Programs\Python\Python37\Scripts)
if you wanna install numpy , now run pip install numpy

When you put your python scripts that have import pandas in the same folder as the site packages like pandas for example and use the same version of python that is used on CMD, it should help run your scripts in IDLE.

Check the path of your code, and that of the module. Copying the module to the path where code is worked for me.
'sys.executable' will give the path where code is stored.

For windows, open command prompt and enter pip show pyodbc to get the path of package and copy the path.
then open idle and run these lines
import sys
sys.path
Match the path from command prompt and the paths mentioned in the list provided by running above lines in IDLE. If the path is not mentioned then run these lines in idle
sys.path.append("Enter the copied path of package here")
After executing these lines, check again by importing the package that if it works for you.

Find Python Installation Directory (Specifically, Python\PythonVERSION) from python [duplicate]

Python is on my machine, I just don't know where, if I type python in terminal it will open Python 2.6.4, this isn't in it's default directory, there surely is a way of finding it's install location from here?

sys has some useful stuff:
$ python
Python 2.6.6 (r266:84297, Aug 24 2010, 18:13:38) [MSC v.1500 64 bit (AMD64)] on win32

>>> import sys
>>> sys.executable
'c:\\Python26\\python.exe'
>>> sys.exec_prefix
'c:\\Python26'
>>>
>>> print '\n'.join(sys.path)
c:\Python26\lib\site-packages\setuptools-0.6c11-py2.6.egg
c:\Python26\lib\site-packages\nose-1.0.0-py2.6.egg

c:\Python26\lib\site-packages\wx-2.8-msw-unicode

In unix (mac os X included) terminal you can do
which python
and it will tell you.

Platform independent solution in one line is
Python 2:
python -c "import sys; print sys.executable"
Python 3:
python -c "import sys; print(sys.executable)"

For Windows CMD run: where python
For Windows PowerShell run: Get-Command python

Have a look at sys.path:
>>> import sys
>>> print(sys.path)

On UNIX-like systems, you should be able to type which python, which will print out the path to python. The equivalent in Windows Command Prompt is where python, and Get-Command python in Windows Powershell.
Another (cross-platform) method is to type this into IDLE or REPL (type python into your terminal):
import re
re.__file__
Or in one line from your terminal:
python -c "import re; print(re.__file__)"
This will print the path to the re module, consequently showing you where the python command points to. You can put any other module that you know is installed, and the path will point to that module, also giving you the path to python.

To find all the installations of Python on Windows run this at the command prompt:
dir site.py /s
Make sure you are in the root drive. You will see something like this.

If you are using wiindows OS (I am using windows 10 ) just type
where python
in command prompt ( cmd )
It will show you the directory where you have installed .

For Windows Users:
If the python command is not in your $PATH environment var.
Open PowerShell and run these commands to find the folder
cd \
ls *ython* -Recurse -Directory
That should tell you where python is installed

First search for PYTHON IDLE from search bar
Open the IDLE and use below commands.
import sys
print(sys.path)
It will give you the path where the python.exe is installed. For eg:
C:\Users\\...\python.exe
Add the same path to system environment variable.

On windows search python,then right click and click on "Open file location".That's how I did

Run below command
where python

Unable to import pyperclip in my python IDLE, but able to import from command prompt

This is my first question on stackoverflow and I'm new to Python.
I want to import pyperclip module.
So I went to cmd, ran as administrator, moved to the path using - cd \Program Files\Python37\Scripts and downloaded pip via pip3 install pyperclip command and it is successfully downloaded.
Now from IDLE I'm not able to import it
Following is the output from IDLE, it has not got that pyperclip module to import
Python 3.8.2 (tags/v3.8.2:7b3ab59, Feb 25 2020, 22:45:29) [MSC v.1916 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license()" for more information.
>>> import pyperclip
Traceback (most recent call last):
File "<pyshell#0>", line 1, in <module>
import pyperclip
ModuleNotFoundError: No module named 'pyperclip'
>>>
After this I did some research I found that, there could be possibility that it must have installed in some other directory. so from the research I found pyperclip folder and pyperclip-1.8.0-py3.6.egg-info folder in one of sub directory, which I copied and pasted in C:\Program Files\Python36 directory.
With above thing also I unable to import pyperclip from IDLE.
I went to command prompt, typed python and able to import it
Following is output
C:\Users\Administrator>python

Type "help", "copyright", "credits" or "license" for more information.
>>> import pyperclip
>>>
So I'm not able to import from IDLE, but able to do in command prompt.
1 more problem I found as I'm new to python,
IDLE is showing python 3.8.2 and on command prompt it is showing 3.6. I have downloaded only 1 python and I have only 1 python installed. why there is this version difference 3.6 and 3.8.2
UPDATE:
With following command on IDLE, I able to import pyperclip. But it is only for current opened IDLE. After closing IDLE and reopening it, I have do these commands again. How to fix it for all time
>>> import sys
>>> sys.path.insert(1, 'C:/Program Files/Python36')
>>> import pyperclip
~~~~~~~~~~
SOLVED:

In your case, IDLE is using one Python interpreter (Python 3.8.2), while in the command-line you run another one (Python 3.6.0), with pyperclip installed. You'd be better off to do ONE of the following steps:
1) use multiple virtual environments to solve this problem easily (recommended). Read this article for more information.
2) install the required module on both Python interpreters, by running pip install pyperclip either (depending on the Python version) from C:\PythonXX\Scripts or C:\Program files\PythonXX\Scripts
3) you may also use single Python interpreter on your machine: remove one of the interpreters and then "Repair" another one (to fix the filetypes associations). To do this, open the installer from Windows uninstall manager and follow the steps it will give you.

I found 1 more python IDLE installed in directory
C:\Users\Administrator\AppData\Local\Programs\Python\Python38-32
I copied pyperclip folder and pyperclip-1.8.0-py3.6.egg-info folder from C:\Program Files\Python36. And it solved my problem thank you guys

I had the same issue but realized this later...what I figured out was that pip was installing the module into the site-packages folder in the AppData\Roaming location instead of the AppData\Local folder. Once I moved the module's folders into the right spot it worked!
If you also run into this issue, maybe just do a quick check that pip is installing where you want it to. Now to figure out how to change the default install path...

Importing a Python module works from command line, but not from PyCharm

My default Python binary is set to the one with the Anaconda distribution of Python. This is found at /home/karnivaurus/anaconda/bin/python, and I have made this the default by adding to my .bashrc file the following: export PATH=/home/karnivaurus/anaconda/bin:$PATH.
I also have a Python package called caffe, which is located at /home/karnivaurus/caffe/distribute/python, and I have added this to the package search path by adding to my .bashrc file the following: export PYTHONPATH=${PYTHONPATH}:/home/karnivaurus/caffe/distribute/python.
Now, I have a simple Python file, called test.py, with the following contents:
import caffe
print "Done."
If I run this by entering python test.py into the terminal, it runs fine, printing out "Done.". The problem I am having is when I run this in the PyCharm IDE. In PyCharm, I have set the interpreter to be /home/karnivaurus/anaconda/bin/python. But when I open test.py in PyCharm, and run the file in the IDE, I get the following error:
ImportError: No module named caffe
So my question is: Why can PyCharm not find the caffe module when it runs the Python script, but it can be found when I run the script from the terminal?

There are a few things that can cause this. To debug, please modify your test.py like so:
# Is it the same python interpreter?
import sys
print(sys.executable)
# Is it the same working directory?
import os
print(os.getcwd())
# Are there any discrepancies in sys.path?
# this is the list python searches, sequentially, for import locations
# some environment variables can fcuk with this list
print(sys.path)
import caffe
print "Done."
Try again in both situations to find the discrepancy in the runtime environment.
edit: there was a discrepancy in sys.path caused by PYTHONPATH environment variable. This was set in the shell via .bashrc file, but not set in PyCharm's runtime environment configuration.

For an additional option, you can use pycharm by terminal. And export the corresponding environment paths beforehand. This works for me. And I think it's better than make some changes in the code. You gonna need run the code by terminal after your debugging.
For example, in terminal type:
$ export LD_LIBRARY_PATH=~/build_master_release/lib:/usr/local/cudnn/v5/lib64:~/anaconda2/lib:$LD_LIBRARY_PATH
$ export PYTHONPATH=~/build_master_release/python:$PYTHONPATH
Then run pycharm by charm (pycharm can be soft linked by charm bash):
$ charm

Well this may be a redundant answer, however I think it's important to explicitly called out what causes this error.
It happened to me many times and I got it fixed by making sure that IDE ( pycharm or vscode or any other) is set to same working directory where the code resided.
for example : I have two files train.py and config.py in mlproject/src directory. I'm trying to run import config in train.py
**When run in /mlproject/ directory, I get error when try to import config **

Python: No module named contextlib?

Does anyone know where i can find this python module 'contextlib'?
root#overo:~# python
Python 2.6.6 (r266:84292, Mar 9 2011, 10:05:36)
[GCC 4.3.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import contextlib
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named contextlib
I did not compile python myself personally. I'm just in this mess. It's running on an ARM based CPU so maybe some things were left out to save space.
I ran find / | grep contextlib which resulted in nothing.
Can i download this module from somewhere and just plonk it in /usr/lib/python2.6? Will that work?

I got this error in a different way.
I created a pipenv virtual environment using the 32bit version of Python 3.6.5 on Windows 10. I then realized I needed the 64bit version. Uninstalled the 32bit, installed the 64bit, and then tried to go back to my existing virtual env. The previously created env was now broken in odd ways and gave me this error.
I solved this by removing the old pipenv pipenv --rm and creating a new one with the newly installed version of python.

As others have noted, that module should be in the standard library, but if it's an embedded device, it may have been dropped to save space (if true, a foolish choice IMO, since leaving out contextlib.contextmanager robs the with statement of much of its power and convenience)
If you can name the specific device or manufacturer (or ask the vendor directly), you may be able to get a better answer.
As far as fixing it goes, grabbing http://hg.python.org/cpython/file/2.6/Lib/contextlib.py and dropping it in sys.path somewhere should do the trick (running python -m site will dump the list of directories that you can use)

It has been part of the standard library since 2.5 according to the docs. It seems a bit weird that you don't have it, it works with 2.6.6 for me (Ubuntu 10.10):
blair#blair-eeepc:~$ python
Python 2.6.6 (r266:84292, Sep 15 2010, 15:52:39)
[GCC 4.4.5] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import contextlib
>>> contextlib.__file__
'/usr/lib/python2.6/contextlib.pyc'
Somebody may have a better suggestion, but if it comes to it there is a link at the top of the documentation to the source code (which is Python, so you should be able to use it directly without any compilation or anything).
Edit: Unless, as Santiago Lezica suggested, you compiled your copy of Python manually, in which case it should be a simple matter of copying the module into the correct library path.
Edit for updated question: To the best of my knowledge, just dropping the source into a directory on the Python path should work. You could do this in the system library, but, to avoid it being deleted/replaced/otherwise borked in future updates, I'd recommend putting it in a separate directory and adding that directory to the Python path. You could put it under /usr/local, or somewhere in your home directory.

With Angsrom Linux, contextlib is included in the python-misc package. You can grab it by running:
opkg install python-misc
This won't, however, get you all expected python modules, so you may also want to install python-modules:
opkg install python-modules

I found one more occasion, which produces the same error.
I had made a virtual environment with python 3.6. After a updated my python version to 3.7 I tried to activate the old virtual environment and got this error.
The solution was to delete the old environment and recreate it with the new python version.

Check sys.path to make sure your python interpreter is looking in the right directories. It should look something like this (not necessarily identical):
>>> import sys
>>> sys.path
['', '/usr/lib/python2.6', '/usr/lib/python2.6/plat-linux2', '/usr/lib/python2.6/lib-tk', '/usr/lib/python2.6/lib-old', '/usr/lib/python2.6/lib-dynload', '/usr/local/lib/python2.6/dist-packages', '/usr/lib/python2.6/dist-packages', '/usr/lib/python2.6/dist-packages/PIL', '/usr/lib/pymodules/python2.6']
EDIT: With the updated information in the question that this is an install of unknown origin on a constrained device, assuming that unnecessary modules were removed to save space makes sense. However, for the record, I'll mention another, perhaps more common scenario where modules cannot be found: when there are file permissions issues. For example:
$ python -c 'import contextlib; print(contextlib.__file__)'
/usr/lib/python2.6/contextlib.pyc
$ ls -l /usr/lib/python2.6/contextlib.py*
-rw-r--r-- 1 root root 4136 Dec 26 16:42 /usr/lib/python2.6/contextlib.py
-rw-r--r-- 1 root root 4127 Jan 1 21:45 /usr/lib/python2.6/contextlib.pyc
$ sudo chmod go-r /usr/lib/python2.6/contextlib.py*
$ python -c 'import contextlib; print(contextlib.__file__)'
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named contextlib
Especially with custom installations, import problems due to file permission issues and path problems are some of the easiest things to check and, usually, to fix.

Python 2
sudo apt-get install python-contextlib2
Python 3
sudo apt-get install python3-contextlib2

contextlib was introduced in Python 2.5, can you remove and re-install your Python 2.6.6 again? From my copy of Python 2.6.6:
