I'm working on a script that will plot data onto a map using the Basemap library. I'm trying to import Shapely as well for use in this same script. I'm working with Anaconda2 for Python2.7 in a Windows 7 environment. I used conda install to download the tar.bz2 file from the Conda Packages site (using Windows command line) and it looked like it all installed correctly.
When I open Pycharm and look at my accessible site-packages, I can see this package. However, when I try to use it within my script, I get an error saying that the package does not exist. I ran the script through the debugger to see if it would shed any more light, but I got the same error. Here's a screenshot of my available site packages when I go to Settings-->Project Interpreter from within Pycharm.
Screenshot of PyCharm site packages available
Is there something special I need to do in order to access this package from within a fresh Python file? I was trying to say "import shapely" or "import osx-64-shapely", but both give me the same "package does not exist" error message. I've been able to successfully use other third-party libraries within Python, so I'm not quite sure what the error is here....
I'm new to SO - if you need more details or there's some piece of info I didn't include, please let me know. Thank you for your help!
EDIT: I am NOT asking what the difference is between conda and pip, or how to use pip within PyCharm. I have used both successfully before to install third-party libraries. What I am asking is what might cause a third-party library that appears to have installed successfully from the command line become inaccessible from within PyCharm when I attempt to import it.
I'm not familiar with Shapely but I was astonished to see the name osx-64-shapely as a site-package for your python installation which is in windows 7. Are you sure you downloaded the right file? :)

As part of a web scraping class I've been instructed to download a few modules from the command terminal (requests, bs4, lxml). These have seemingly been successfully downloaded to my computer, yet my Jupyter Notebook AND PyCharm virtual environment cannot find them.
I am a beginner so I'm sure there are some big things I'm missing, any help would be appreciated.
How did you install Jupyter?
Wich package manager are you using? (eg. what did you type to install the packages?)
Wich modules can it find and which not?
Usually you want to make sure your modules are available in the environment you are using. ( Enviornments are like "versions" of python. You could run multiple versions like 3.7 and 3.9 on your Computer but also also different builds from one python version.)
Pycharm builds its own environment. Make sure you use the enivorment you installed your packages to in Pycharm. Pycharm allows you to modify and create new environments very easily
For PyCharm it might be useful to check out their help page.
I figure this could help: https://www.jetbrains.com/help/pycharm/configuring-python-interpreter.html#add_new_project_interpreter
The interpreter is basicly the a customized version of python. Pycharm keeps track of the modules you need for every project. So you want to create/select an interpreter which has the packages you have installed.
hope it helps
cheers
This is a very vague question but I am really stuck. I have been working with python for a little bit to try and use some of their functions in opencv (cv2) and other open source libraries. But whenever I try and use pip I will always get an error about improper installation or more commonly when trying to import the installed package idle throws an error that a line of code in the library that is causing an exception. This does not just happen to one library but nearly all of them (I have tried stuff like opencv, tensorflow, urllib). I have tried reinstalling different versions of python (multiple times) and reinstalling it but none of that seems to work. I don't know what to do but really want to be able to use these tools. I use windows 10 and use the default "User" user on admin.
Any help on possible options would be most appreciated!
This was happening to me as well.
In my case I wanted to work with Anaconda and Spyder. I was following some books and tutorials saying how to install stuff with the pip and so on, but it didn't work. What solved it was to install PyCharm and use those same pip functions directly on the PyCharm console (not the windows cmd). Then everything worked automatically and I have whatever library I installed from PyCharm available at Spyder without doing anything else.
Summary:
Get Pycharm -> link
use the same pip install directly in the PyCharm console
A-Hopefully it will work
If it doesn't: Can you elaborate on which IDE are you using? Most likely there is someone here who can help you.
I'm trying to install OpenCV into my python environment (Windows), and I'm almost all of the way there, but still having some issues with autocomplete and Pycharm itself importing the library. I've been through countless other related threads, but it seems like most of them are either outdated, for prebuilt versions, or unanswered.
I'm using Anaconda and have several environments, and unfortunately installing it through pip install opencv-contrib-python doesn't include everything I need. So, I've built it from source, and the library itself seem to be working fine. The build process installed some things into ./Anaconda3/envs/cv/Lib/site-packages/cv2/: __init__.py, some config py files, and .../cv2/python-3.8/cv2.cp38-win_amd64.pyd. I'm not sure if it did anything else.
But here's where I'm at:
In a separate environment, a pip install opencv-contrib-python both runs and has autocomplete working
In this environment, OpenCV actually runs just fine, but the autocomplete doesn't work and Pycharm complains about everything, eg: Cannot find reference 'imread' in '__init__.py'
Invalidate Caches / Restart doesn't help
Removing and re-adding the environment doesn't help
Deleting the user preferences folder for Pycharm doesn't help
Rebuilding/Installing OpenCV doesn't help
File->Settings->Project->Project Interpreter is set correctly
Run->Edit Configuration->Python Interpreter is set correctly
So my question is: how does Pycharm get or generate that autocomplete information? It looks like the pyd file is just a dll in disguise, and looking through the other environment's site-packages/cv2 folder, I don't see anything interesting. I've read that __init__.py has something to do with it, but again the pip version doesn't contain anything (except there's a from .cv2 import *, but I'm not sure how that factors in). The .whl file you can download is a zip that only contains the same as what 'pip install' gets.
Where does the autocomplete information get stored? Maybe there's some way to copy it from one environment to another? It would get me almost all the way there, which at this point would be good enough I think. Maybe I need to rebuild it with another flag I missed?
Got it finally! Figures that would happen just after posting the question...
Turns out .../envs/cv/site-packages/cv2/python-3.8/cv2.cp38-win_amd64.pyd needed to be copied to .../envs/cv/DLLs/. Then PyCharm did it's magic and is now all good.
Alternatively add the directory containing the .pyd file to the interpreter paths.
I had exactly this problem with OpenCV 4.2.0 compiled from sources, installed in my Conda environment and PyCharm 2020.1.
I solved this way:
Select project interpreter
Click on the settings button next to it and then clicking on the Show paths for selected interpreter
adding the directory containing the cv2 library (in my case in the Conda Python library path - e.g. miniconda3/lib/python3.7/site-packages/cv2/python-3.7). In general check the site-packages/cv2/python-X.X directory)
I am using PyCharm to develop a python project, which uses an external library called win10toast. I have installed win10toast using PyCharm. However, when I tried to run the .py file using cmd (i.e Externally running the python file), an error shows up:
ModuleNotFoundError: No module named 'win10toast'.
I have python 3.6.4. I installed win10toast using PyCharm.
from win10toast import ToastNotifier
I expect the program to run without any error, but currently I am getting the ModuleNotFound error.
Python can be tricky to run properly because it is sensitive to where you installed your dependencies (such as external libraries and packages). If you installed Python to one directory, but accidentally installed the external library to another directory, when you run your .py program, it will be unable to call from the external library because it doesn't exist in the same library that Python is running from.
Lookup where you installed Python on your computer and then find where you installed the external library. Once your find where you installed the external library, move its entire package content to the same directory where Python is installed. Or better yet, reinstall the external library with pip into the same directory as Python.
If you're on Mac, Python and its related dependencies are usually stored somewhere in /User/bin. If you're on Windows, it will be stored somewhere in your C:// directory (possibly somewhere in C:\Users\username\Local\AppData). If you're on Linux, it will be stored somewhere in /usr/bin. Whatever you do, don't move Python from wherever it is because sometimes that can mess up your system for certain operating systems like Mac, which comes with its own version of Python (Python 2.7 I believe, which is outdated anyway).
Lastly, you may have two different versions of Python on your computer, which is common; Python 2.7 and Python 3+. If you wrote your program in one version, but ran it from the other, the external library can only be called from whichever Python version you installed it to. Try running your .py program with python3 instead of python (or vice versa) and see what happens. If it works with one python version over the other, that tells you that the external library is installed in the other version's directory.
That should solve your issue.
I would suggest that you not use PyCharm to install packages, at least not
if the result deviates in the slightest from doing a "pip install" at the command line. I see no reason to involve PyCharm in configuring Python installations. It's just asking for trouble.
I admit that I'm not familiar with the practice I'm suggesting you avoid. I've been using PyCharm since pretty much the week it came out (was an avid user of the IntelliJ Python plugin before that), and have never once considered doing anything but installing Python modules at the command line. That way, I'm sure right where those modules are going (into which base Python install or venv). Also, I know I'm doing all that I can to minimize the differences that I might see between running code in PyCharm and running it at the command line. I'm making my suggestion based solely on this practice having never gone wrong for me.
I have multiple base Python versions installed, and dozens of venvs defined on top of those. PyCharm is great at allowing me to indicate which of these I want to apply to any project or Run/Debug configuration, and utilizing them seamlessly. But agin, I administer these environments at the command line exclusively.
I still experience issues in switching between the command line and PyCharm in terms of one module referencing others in a single source tree. My company has come up with a simple solution to this that insures that all of our Python scripts still run when moving away from PyCharm and its logic for maintaining the Python Path within a project. I've explained the mechanism before on S.O. I'd be happy to find that if anyone is interested.
The library win10toast installed in the directory: YOUR_PYCHARM_WORKSPACE\PycharmProjects\YOUR_PROJECT_NAME\venv\Lib\site-packages
but when you are running your program using cmd, pycharm interpreter uses site-packages directory that you installed python at there. for Ex: C:\Python27\Lib\site-packages
So, you can install the win10toast library to this windows directory using pip.
I installed OpenERP 6.1 on windows using the AllInOne package. I did NOT install Python separately. Apparently OpenERP folders already contain the required python executables.
Now when I try to install certain addons, I usually come across requirements to install certain python modules. E.g. to install Jasper_Server, I need to install http2, pypdf and python-dime.
As there is no separate Python installation, there is no C:\Python or anything like that. Where and how do I install these python packages so that I am able to install the addon?
Thanks
Please check this link, may be helpful for you.
http://www.zbeanztech.com/blog/openerp-source-eclipse-under-windows
if you install the python package separately, then you have to add the bin path of the installed package to the system environment variable.
Good question..
Openerp on windows uses a dll for python (python26.dll in /Server/server of the openerp folder in program files). It looks like all the extra libraries are in the same folder, so you should be able to download the extra libraries to that folder and restart the service. (I usually stop the service and run it manually from the command line - its easier to see if there are any errors etc while debugging)
Let us know if you get it working!
