import numpy
is not working. This started because I couldn't get PyQt5 to work on my home computer. In the Spyder IDE, I can import modules and get everything working fine, but in VS Code, I can't import basic modules. I'm on Windows 10 with Python 3.7. I've Googled a lot and have tried these:
Uninstall Anaconda and VS Code, and reinstall both
In VS Code, press Ctrl+Shift+P, Select Interpreter, and select Python 3.7.1 64-bit ('base':conda), ~\Anaconda3\python.exe
I saw on another similar question that python3.dll may be missing from one of my Anaconda directories, but it is indeed there.
Add environment variable to PATH by going to System Properties > Advanced tab > Environment Variables... > under System Path, Edit, New > C:\Users\myname\Anaconda3\Scripts
Once I did #4 above, the new error message in VS Code when importing numpy is DLL load failed: The specified module could not be found. And in the terminal, I see: The term 'conda' is not recognized as the name of the cmdlet, ...
One thing I notice is in a Python prompt (not Anaconda) I type:
import sys
print(sys.version)
The output is 3.7.2, while in VS Code, the Select Interpreter (see above #2) says Python 3.7.1. Not sure if this is important.
Any help? Everything works on my work computer fine, but it's just my home computer that is being difficult.
What ended up working for me is downgrading my Python installation from 3.7.1 to 3.6.4 with:
conda install python=3.6.4
Hope this helps someone out there.
On another question for the same problem, there was a suggestion that worked for me.
Put this on the variable path.

I'm having trouble right now with PyAutoGUI. I have installed it in:
C:\msys64\mingw64\lib\python3.9\site-packages
but VS Code doesn't seem to recognize it.
I get this message:
Import "pyautogui" could not be resolved from source
I've already tried reinstalling everything, set paths and verify installations.
Use Ctrl+Shift+P --> Python:Select Interpreter to select the correct interpreter.
If there are multiple python versions on your machine, you need to use the one that has the pyautogui package installed.
You can check the current interpreter path with the following code.
import sys
print(sys.executable)
I am running IPython Notebook on Enthought's Canopy 64 bit distribution, Ubuntu 14.04.
I've tried install libtiff, but when I import it in IPython Notebook, the kernel always dies at the import statement. What could possibly be causing this? Canopy is my default Python distribution, my paths all seem like they're set up appropriately, although I'm convinced that something in my Python setup is borked.
Any advice is appreciated.
EDIT: I'll be more specific. Output of sys.path:
['',

As for how to install Python packages, I assume I go to ~/Enthought/Canopy_64bit/User/lib/python2.7/site-packages and run pip, setup.py, or a shell script, per the specific package's instructions. Is that correct? The article that I linked has the following line: "To install a package which is not available in the Canopy / EPD repository, follow standard Python installation procedures from the OS command line.", which seems to imply that I install per package instructions.
In .bashrc, I have the following:
VIRTUAL_ENV_DISABLE_PROMPT=1 source /home/joe/Enthought/Canopy_64bit/User/bin/activate
export PYTHONHOME=/home/joe/Enthought/Canopy_64bit/User/bin
export PATH=/home/joe/Enthought/Canopy_64bit/User/bin
export PYTHONPATH=/home/joe/Enthought/Canopy_64bit/User/bin
From what I understand of the linked articles, this means I'm setting Canopy User as my default Python distribution. I'm sure I'm doing something a bit over my head here, but I can't understand what else I need to do to fix this issue.
Worse yet, now I'm getting an "ImportError: No module named site" with these .bashrc settings, when trying to start IPython notebook or python from the command line. I can run only from the Canopy GUI.
Closing this. I made it harder than necessary.
It turns out, the PYTHONHOME and PYTHONPATH .bashrc variables were causing some conflicts. Commenting them out seems to have resolved the issue.
Installing outside packages does, indeed, happen from the home (~) directory.
I would like to use arcpy into Anaconda's Spyder. I have a full ArcGIS license, so this is not an issue. I am able to semi-import the module by way of copying the the arcpy folder out of C:\Program Files (x86)\ArcGIS\Desktop10.1\arcpy and into C:\Anaconda\Lib\site-packages, but the import is never completed because I get an error of "ImportError: No module named arcgisscripting". Is there any way for arcpy to work in Spyder?
This is what you need to do:
Open the Python window in ArcGIS, as described here
In there run these two commands:
import sys
sys.executable
Copy the output of the last command
Open Spyder and go to
Tools > Preferences > Python interpreter
Select the option
Use the following Python interpreter
and paste there the result of step 3.
Finally go to Consoles > Open an IPython console. This will open a new console that will be running the same Python version that comes with ArcGIS but inside Spyder. So you could run there whatever command you can run in ArcGIS Python Window.
Note: It is possible that this doesn't work if the Python that comes with ArcGIS doesn't have the ipykernel package.
To address this, browse to the python27\Lib\site-packages folder, mine was located under "C:\Python27\ArcGIS10.1\Lib\site-packages", and find the file Desktop10.1.pth.
On my system, the problem was resolved by simply copying the Desktop10.1.pth file into "C:\AppData\Local\Continuum\Anaconda\Lib\site-packages".
If you are running Anaconda 64 bit, you will get a different error when you try to import arcpy because ArcGIS runs 32 bit. Therefore, you have to make sure that you have the Anaconda 32 bit installed rather than 64 bit so things match up with ArcGIS. Once the file is copied and you have Anaconda 32 bit, import arcpy should work.
The only thing worked for me is: I just copied the arcpy folder from 'C:\Program Flies(x86)\ArcGIS\Desktop10.3' and pasted that into my '~Anaconda3\Lib\site-packages'. Now I can import arcpy into spyder of Anaconda3.
I get "Undefined variable from import" error in Eclipse 3.7.2 PyDev 2.7.1 on Linux Mint Maya (Cinnamon) whenever I import a module from numpy. The problem only arises when importing numpy; other modules work just fine.
Info: numpy is compiled against the Intel MKL libraries. Python 2.7.3 [GCC 4.6.3]
example:
import numpy as np
a = np.array([1, 2])
Error message in PyDev editor:
"Undefined variable from import: array"
I get similar errors for other numpy submodules.
The code runs properly either within Eclipse or in a terminal. The problem is only present in the Eclipse-PyDev editor.
The LD_LIBRARY_PATH has to contain paths to the MKL libraries. Even if LD_LIBRARY_PATH is set properly, it has to be explicitly specifed in Eclipse under Window > Preferences > Interpreter - Python, under the "Environment" tab on the right hand side. Add a new variable called "LD_LIBRARY_PATH" and paste the content of $LD_LIBRARY_PATH.
Once it is done, errors will only disappear from your code if a line is added to the code which uses a numpy object so that imports are checked again.
I managed to fix it by updating the Phyton interpreter in Eclipse. Just click on Apply button after successfully installed Numpy module.
Are MKL libraries and numpy the same thing? #user1898039's answer didn't make sense to me (I'm not sure what path I should use for that property.
I found another way to fix this issue - I checked the python command line to see if numpy was installed there by calling:
>>> import from numpy *
It was not. So, despite the fact that numpy was showing up in PyDev under the "Forced Builtins" tab in the Python Interpreter properties, it wasn't available to python from the command line and I imagine this caused the issue inside PyDev.
So, I fixed the problem by going to the numpy site and installing the newest version for windows. Technically I went to some other site that had a AMD64 version of the installer for windows, buy you know, same same. After that I tried to get the PYTHONPATH variable to recalculate all the libraries (this may have been unnecessary), but errors were still showing in the file on all the calls to array(). I did an autocomplete on the numpy package to get the list of functions, selected array() from that list, and all of the sudden all the errors cleared and everything is fine now.
I was able to resolve this by adding the following path to PYTHONPATH (Pydev => Python Interpreters => select an Interpreter => Libraries):
/usr/local/anaconda/lib/python2.7/lib/lib-dynload
installed packages (among others):
conda==3.10.1
numpy==1.9.2
scipy==0.15.1
I occasionally see these errors for pandas objects, after re-starting Eclipse, even though I of course have 'import pandas as pd' at the top of my file.
I've discovered a simple workaround: I simply delete the import statement, save the file, paste it back in and re-save. The errors go away!
I'm on this version of Eclipse:
Eclipse for PHP Developers
Version: Mars.2 Release (4.5.2)
Build id: 20160218-0600
I'm working off the latest Mac OS trying to set up my programming environment. Right now what I want to do is to get Pygame working with Pydev so I can do my Python programming from Eclipse. What I've done so far is installed Python 2.6 from python.org and then installed pygame 1.9 from the site.
What happens is that when I try running Python from the command line, I am able to import pygame without a hitch, but when I try to do the same thing from Eclipse, it doesn't work.
I think it might be because Pydev doesn't know where to find Python, in which case I would like some help on how to make sure it's pointing to the right one.
Thanks!
I work with Eclipse on Windows, but I believe that the Mac version eclipse should be the same.
In Eclipse,
click Windows > Preferences,
expand PyDev from left side,
find Interpreter - Python,
switch to Libraries tab,
click New Folder on the right hand,
navigate to your pygame path, and
click Apply and OK.
Turn to your Python project in eclipse,
right click on it,
choose PyDev - Interpreter/Grammar,
choose Python as Project type,
choose 3.0 or your correspond Python version from Grammar,
at last make sure the Interpreter you are using is the same as the one you just configured.
Build your project from eclipse, and it should work.
In Eclipse, Window->Preferences, expand Pydev and choose Interpreter - Python. Then specify your python path. Try first by clicking "Auto Config" to auto-locate your python installation. Then click Apply and Ok.
Make sure this much works by creating a new Python project (without worrying about Pygame yet).
I tested these instructions from Eclipse Helios on Windows. Hope it works for you.
http://www.vogella.de/articles/Python/article.html
If autoconfig is not finding 2.6 you can add it manually at Preferences/PyDev/Interpreter - Python. There you have to press New and set the path for your Python executable.
For Python2.6 the path is: /System/Library/Frameworks/Python.framework/Versions/2.6/bin/Python2.6
For Python2.7 (and higher), the path is different:
/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7
Those paths work on OS X 10.6.8, might change for other versions.
Do what the people says, and if that does not work, make sure that you have downloaded the development package.
On menu Window > Preferences > PyDev > Interpreters > Python Interpreters
If your python interpreter config have a pygame and don't work, try to put on force bultins the new keyword "pygame"
Python part
Install Python 3.5.2 32 bits (From python.org)
Download the right pyGame library for 3.5.x 32 bits (It will be pygame-1.9.2b1-cp35-cp35m-win32.whl)
Open the system console and go to the folder where the library was download.
Write in the console: pip install pygame-1.9.2b1-cp35-cp35m-win32.whl
This should install the pygame library.
Note: If the pip version is not the last one, upgrade it. (In this step you should know how, just pay attention.)
Eclipse Part
Open Eclipse
Go to Help>Install new software.
Look for the botton "Add" in the right top corner.
In Location put http://pydev.org/updates. Put a cute name, too. Then click OK.
Check pyDev checkbox. Go next, Finish. Accept licenses. In simple words: Install it.
Go to Window>Preferences>pyDev>Interpreters>Phyton interpreter.
In the Python interpreters part, click Quick Auto-Config.
Note: If you want to do this manually, you should know the path where you installed Python and search for python.exe
Some libraries should manifest in the libraries tab. Click apply.
In the libraries tab, click New Folder.
Search for PyGame installation path (In my case, C:\Python\Python35-32\include\pygame but it's always on Python installation path plus include\pygame, ok?)
Click Accept.
Go to Forced Builtins tab. Click New... and add 'pygame'.
Apply again ! (You should know that I do this only for safety. You can apply just one time.
Click OK.
Test
File> New> Proyect...> PyDev> PyDev Proyect.
Click Next
Complete the Proyect Name. On Grammar Version combobox, select 3.0 - 3.5 and in interpreter choose python.
Note: "Quick Auto-Config" named "python" to the interpreter. If you did this part manually, you should know the exact name because you named it.
Try simple code
import pygame
print(pygame.ver) # This should print the pygame version.
pygame.init() # This does nothing by now, just checking code.
I wasted forever trying to get this to work as well..
I eventually found these steps (you don't need them all just part of my struggles shared).
in Python Shell:
import sys
print (sys.path)
Noticed NO PYGAME in path.
Eventually I GAVE UP on the .exe binaries and was told to use .WHL files and Python PIP to install. but was told NOT VALID wheel file. (frustrating).
what EVENTUALLY WORKED was to (in windows, but similar should work in other OS's).
run Command Prompt as Administrator (just to be sure) Maybe same in other OS's. you'd have to try.
from C:> i Changed Dir to my Python.exe (or the python program itself).
from my python directory in command prompt I typed the following (Like I would a Linux apt-get install command):
**
python.exe -m pip install pygame
**
Shortly after, there were hash marks ##### indicating a download was taking place (Linux type progress bar in shell).
in ECLIPSE without ever changing the Libraries folder to include PyGame folders I was able to run a sample Python PYGAME Script sample (I got a white screen but haven't gone further yet). I was just HAPPY to not have to see the trace back error message :)
now I am finished typing this to you I will be going to test it out further.
Just thought this would help someone :0)
I met such problem in Python 3.6 using LiClipse (which should be similar as Eclipse). It's solved by import pygame as
import pygame
from pygame.locals import *
Then add the pygame folder to Window>Preferences>PyDev>Interpreters>PyDev>Libraries, type in 'pygame' in the Forced BuiltIns tab at the same page, also right click the project, change Properties>PyDev-PYTHONPATH>Source from {proj_dir_name}/ to {proj_dir_name}/src
Maybe some above steps are not necessary. Anyway doing all aboves solves the problem in my case.
