I am trying to import the scikit and dlib library in my editor. However, it shows module not found. Also, when I try to download the module, it shows that it already exist. I can easily open juptyer notebook via command line.
Even when it asks for password for root permission, it shows:
File "/lib/security/howdy/compare.py", line 17, in <module>
import dlib
ModuleNotFoundError: No module named 'dlib'
Unknown error: 1
However, when I try to install dlib, it shows that it is already installed in the anaconda directory.

I'm trying to get pyttsx3 to work in pycharm. I did a "pip3 install pyttsx3". "pip3 list" shows it to be available. I get the following when I try to run the module in pycharm:
from pywiktionary import WiktionaryParserFactory
ModuleNotFoundError: No module named 'pywiktionary'
It does the same thing for pyttsx3. Installs under pip, but get the same "ModuleNotFoundError: No module named 'pyttsx3'.
It's like they exist at one place for pip and another place for pycharm. I even uninstalled/installed pycharm. What defines where the python modules are put in the system?
I have successfully finished the first problem I had with pip.main being moved, but I installed pyfirmata which I am using for my Arduino UNO, but even though I used pip and successfully installed it, there was still an error that said "package pyfirmata not found". I don't understand this. This is my code:
#install pyfirmata
import pip
from pip._internal import main as pipmain
pipmain(['install', 'pyfirmata'])
#import pyfirmata
from pyfirmata import Arduino, util
import time
board = Arduino('') #put port into "('')"
if you are getting error no module named pyfirmata and it is sucessfully installed than again type pip install pyfirmata you see requirment satisfy and location of site packages open location search pyfimata and locate pyfirmata file to your project directory
now it possible pyfirmata need more module so also locate them with in the directory
So I've installed scons via Anaconda's conda install scons under Windows 10 (Python 3.6) and could not execute it via the command line so I've added C:\Users\D\Anaconda3\envs\py36\Scripts\ to my Path (even tough C:\Users\Dominik\Anaconda3 was already in there).
Now I can execute it in the Powershell, but I get an error, because it is unable find engine files:
scons
SCons import failed. Unable to find engine files in:

Traceback (most recent call last):
File "C:\Users\D\Anaconda3\envs\py36\Scripts\scons.py", line 192, in <module>
import SCons.Script
ImportError: No module named 'SCons'
Does someone know how to further investigate/fix this problem?
I found it thanks to nekomatic.
If you use the anaconda prompt (with the correct environment activated or in my case the correct shortcut leading to anaconda prompt in that environment), scons runs just fine.
See this link explaining how anaconda uses the path on windows and whats the advantage of using the anaconda prompt (mainly it dynamically manages PATH correctly for that session only with full knowledge of conda environments).
I used to install python (2.7.6) packages using sudo pip install [...] until I recently decided that this was a bad idea and I should use: pip install --user [...] instead.
Since I am using Mac OS X (10.10.3), my python modules had been installed into /Library/Python/2.7/site-packages. Now, with the --user option enabled, they are being installed into: /Users/USER/Library/Python/2.7/lib/python/site-packages
I have since moved all packages (including pip/setuptools) into this destination, adjusted my $PYTHONPATH and changed the file ownership to my local user. I expected that I would now be able to call pip install --user [..] and everything should go smoothly.
Unfortunately, this is not the case. For any pip install (or pip install --upgrade) command I receive the same error (below). The same is true when using a virtualenv - the same error shows up and I have no clue why.
However, everything does work "fine", when I use sudo pip install --user, which is why I assume that it is somehow related to a file-permission error I can not see. (It's not exactly fine, as the newly installed package will be in the right location, but all files are owned by root.)
Any idea what I am doing wrong or how to debug this?

I also checked the location of pkg_resources and deleted pkg_resources.pyc, which is located in /usr/local/lib/python2.7/site-packages for some reason, but it didn't change anything. (My local user also has full access rights in this location.)
[UPDATE:]
For some reason I was able to install virtualenv without root (pip install --user virtualenv), but all other packages I tried still fail. Also, if I switch to a new virtual environment, I still receive the same error. I am now thinking this is related to my $PYTHONPATH variable, which appears to not be updated for my virtualenv, but I haven't found the real solution, yet.
Alright, so I found the actual problem and solution. My $PYTHONPATH contained an invalid directory. I setup my $PYTHONPATH a long time ago and wrote it into a .bashrc (or more accurately .bash_profile) script.
pip was probably looking through all directories in $PYTHONPATH, although I don't know what it is doing in each of them that causes the above error, but removing the invalid directory fixed my problems.
I also now highly recommend to just use virtualenv instead of a static setup.
I am using Python 2.7 through Anaconda 2.7.8 and need Kapteyn 2.2 to perform Non-linear Least Squares fitting easily (it is probably an alternative to Scipy.optimize.leastsq() for dummies like me!).
After copy-pasting this from a previous post here on Stack Overflow:
conda install -c https://conda.binstar.org/dhirschfeld pyodbc
and then running on my cmd (as I did not have pyodbc installed I think, because of which maybe the command prompt on my Windows 7 64-bit system was not responding well to python setup.py install inside the Anaconda directory where I unzipped the Kapteyn .zip file downloaded from University of Groningen website.
But, after the installing pyodbc properly and running python setup.py install, the cmd gave me an error saying error: command 'C:\Users\windows 7\Anaconda\Scripts\gcc.bat' failed with exit status 1. Later, when I tried to import kmpfit module (needed for Non-linear least square fitting with Kapteyn), here is the problem:
import kapteyn
help(kapteyn)

As you can see, there is no module named kmpfit (or even wcs) here. But according to http://www.astro.rug.nl/software/kapteyn/intro.html, these two should be there.
Kindly help. I have never imported any module before.
Thanks in advance...:-)
I just managed to get this working (on Mac OSX, so you may have to adjust this). My steps were:
$ conda install pyodbc (didn't need to go through binstar)
Download & unarchive the kapteyn package, then navigate to its directory
$ python setup.py install, which used my OS's C compiler and Anaconda's python, and installed kapteyn to my anaconda distro's site-packages, as it should.
Check that kmpfit.so is in the kapteyn folder in site-packages, showing that kmpfit installed correctly.
>> from kapteyn import kmpfit failed, ImportError: cannot import name kmpfit. I did some digging and discovered that it was still importing kapteyn from the folder that I downloaded, not from site-packages.
Delete the downloaded kapteyn folder, then try again. It worked!
