PyCharm's autocomplete isn't working for installed libraries. I have the following code:
from boto.emr.connection import EmrConnection
conn = EmrConnection(aws_keys.access_key_id, aws_keys.secret_key)
I want the editor to tell me what methods I have available to me when I press Ctrl+Space.
The boto library is installed in my environment, but it doesn't seem to be detected by PyCharm. How can I set this up correctly?
You've installed the 3rd-party library into a virtualenv, but PyCharm doesn't know about that by default. If nothing is specified, it will choose the system Python install as the interpreter. You need to go into the project settings and configure the interpreter to point at the virtualenv. PyCharm will then index the interpreter and allow you to autocomplete.
The virtualenv may be auto-detected in the dropdown menu on the left. If it is not, click the gear to the right, click "Add local", and select /path/to/virtualenv/bin/python (or \Path\to\virtualenv\Scripts\python.exe on Windows).
The above answer didn't work for me, because I wasn't able to find any project related setting in my setting,and the python Interpreter was empty.
The solution was to delete .idea file, from project root, close Pychram then go to project directory and open it with Pycharm:
$pycharm-professional or $pycharm-professional .
when it lunch a pop up window on the bottom right will appear and as you the following
select configure python interpreter then a new window must appear:
chose to use Pipenv as your interpreter or any other solution that is for your case.
Now the Project setting should appear again in Pycharm setting, and the recommendation must be already working.
In PyCharm, I've added the Python environment /usr/bin/python. However,
from gnuradio import gr
fails as an undefined reference. However, it works fine in the Python interpreter from the command line.
GNURadio works fine with python outside of Pycharm. Everything is installed and configured how I want it.
Gnuradio is located at /usr/local/lib/python2.7/site-packages/gnuradio
Also:
PYTHONPATH=/usr/local/lib/python2.7/site-packages:/usr/local/lib/python2.7/site-packages/gnuradio
Adding a Path
Go into File → Settings → Project Settings → Project Interpreter.
Then press configure interpreter, and navigate to the "Paths" tab.
Press the + button in the Paths area. You can put the path to the module you'd like it to recognize.
But I don't know the path..
Open the python interpreter where you can import the module.
>> import gnuradio
>> gnuradio.__file__
"path/to/gnuradio"
Most commonly you'll have a folder structure like this:
foobarbaz/
gnuradio/
__init__.py
other_file.py
You want to add foobarbaz to the path here.
You should never need to modify the path directly, either through environment variables or sys.path. Whether you use the os (ex. apt-get), or pip in a virtualenv, packages will be installed to a location already on the path.
In your example, GNU Radio is installed to the system Python 2's standard site-packages location, which is already in the path. Pointing PyCharm at the correct interpreter is enough; if it isn't there is something else wrong that isn't apparent. It may be that /usr/bin/python does not point to the same interpreter that GNU Radio was installed in; try pointing specifically at the python2.7 binary. Or, PyCharm used to be somewhat bad at detecting packages; File > Invalidate Caches > Invalidate and Restart would tell it to rescan.
This answer will cover how you should set up a project environment, install packages in different scenarios, and configure PyCharm. I refer multiple times to the Python Packaging User Guide, written by the same group that maintains the official Python packaging tools.
The correct way to develop a Python application is with a virtualenv. Packages and version are installed without affecting the system or other projects. PyCharm has a built-in interface to create a virtualenv and install packages. Or you can create it from the command line and then point PyCharm at it.
$ cd MyProject
$ python2 -m virtualenv env
$ . env/bin/activate
$ pip install -U pip setuptools # get the latest versions
$ pip install flask # install other packages
In your PyCharm project, go to File > Settings > Project > Project Interpreter. If you used virtualenvwrapper or PyCharm to create the env, then it should show up in the menu. If not, click the gear, choose Add Local, and locate the Python binary in the env. PyCharm will display all the packages in the selected env.
In some cases, such as with GNU Radio, there is no package to install with pip, the package was installed system-wide when you install the rest of GNU Radio (ex. apt-get install gnuradio). In this case, you should still use a virtualenv, but you'll need to make it aware of this system package.
$ python2 -m virtualenv --system-site-packages env
Unfortunately it looks a little messy, because all system packages will now appear in your env, but they are just links, you can still safely install or upgrade packages without affecting the system.
In some cases, you will have multiple local packages you're developing, and will want one project to use the other package. In this case you might think you have to add the local package to the other project's path, but this is not the case. You should install your package in development mode. All this requires is adding a setup.py file to your package, which will be required anyway to properly distribute and deploy the package later.
Minimal setup.py for your first project:
from setuptools import setup, find_packages
setup(
name='mypackage',
version='0.1',
packages=find_packages(),
)
Then install it in your second project's env:
$ pip install -e /path/to/first/project
For me, it was just a matter of marking the directory as a source root.
Add path in PyCharm 2017
File -> Settings (or Ctrl+Alt+S) -> Project -> Project Interpreter
Show all
Select bottom icon on the right side
Click on the plus button to add new path to your module
My version is PyCharm Professional edition 3.4, and the Adding a Path part is different.
You can go to "Preferences" --> "Project Interpreter". Choose the tool button at the right top corner.
Then choose "More..." --> "Show path for the selected interpreter" --> "Add". Then you can add a path.
DON'T change the interpreter path.
Change the project structure instead:
File -> Settings -> Project -> Project structure -> Add content root
In PyCharm 2020.1 CE and Professional, you can add a path to your project's Python interpreter by doing the following:
1) Click the interpreter in the bottom right corner of the project and select 'Interpreter Settings'
2) Click the settings button to the right of the interpreter name and select 'Show All':
3) Make sure your project's interpreter is selected and click the fifth button in the bottom toolbar, 'show paths for the selected interpreter':
4) Click the '+' button in the bottom toolbar and add a path to the folder containing your module:
For PyCharm Community Edition 2016.3.2 it is:
"Project Interpreter" -> Top right settings icon -> "More".
Then on the right side there should be a packages icon. When hovering over it it should say "Show paths for selected interpreter". Click it.
Then click the "Add" button or press "alt+insert" to add a new path.
As quick n dirty fix, this worked for me:
Adding this 2 lines before the problematic import:
import sys
sys.path.append('C:\\Python27\\Lib\site-packages')
On Project Explorer, you can right click on the folder where the module is contained and set as 'Source'.
It will be parsed in the Index for code completion as well as other items.
I'm new to PyCharm (using 2018.3.4 CE) and Python so I rotely tried to follow each of the above suggestions to access the PIL (Pillow) package which I knew was in system-site-packages. None worked. I was about to give up for the night when I happened to notice the venv/pyvenv.cfg file under my project in the Project Explorer window. I found the line "include-system-site-packages = false" in that file and so I changed it to "true". Problem solved.
In my PyCharm 2019.3, select the project, then File ---> Settings, then Project: YourProjectName, in 'Project Interpreter', click the interpreter or settings, ---> Show all... ---> Select the current interpreter ---> Show paths for the selected interpreter ---> then click 'Add' to add your library, in my case, it is a wheel package
For me there is also another issue. If you try to add a folder that in the past had a .idea folder, but your current project has it's own .idea folder your pycharm might get confused for some reason -- even if you have the right python/conda env. For me deleting the .idea folder of the other project fixed the confusion that it could find the obviously correctly installed pkgs. Then it was it was able to find them in the pycharm editor GUI snf stopped underlyinging them in red.
Download anaconda

once done installing anaconda...
Go into Settings -> Project Settings -> Project Interpreter.
Then navigate to the "Paths" tab and search for /anaconda/bin/python
click apply
Python newbie here. I am on windows. I installed anaconda a while back for my own user account (not for all users on windows). It installed into c:\users...\local..anaconda and all is good. I might have recently updated anaconda and installed VS 2017.
Now I seem to have 4 python environments.
I tried uninstalling from add-remove programs but some how the environments did not go away.
My questions:
1. Where does Visual Studio get the list of environment names?
2. How do I delete these environments? I just want to keep one and delete all the others
I deleted the unwanted registry keys from (what solved the problem for me):
HKEY_CURRENT_USER\Software\Python\PythonCore\
The source mentions also the following keys, but they did not exist in my computer:
HKEY_LOCAL_MACHINE\Software\Python\PythonCore\
HKEY_LOCAL_MACHINE\Software\Wow6432Node\Python\PythonCore\
Source: https://github.com/Microsoft/PTVS/issues/18
I found my answer to this question here : https://learn.microsoft.com/en-us/visualstudio/python/managing-python-environments-in-visual-studio?view=vs-2019#fix-or-delete-invalid-environments
First click this button
You will then see this kind of screen
Then click the dropdown menu where it shows - packages. Then click the overview tab.
Click the delete/remove the enviroment.
Your enviroment should now be removed.
This is the link to read
I'll quote you what I think is relevant for your case, but if it's not, just read it all and find what you need
Any global environment can be added as a project environment by
right-clicking Python Environments and selecting Add/Remove Python
Environments.... From the displayed list you can select or deselect
those environments that are available in your project.+
And...
Once a virtual environment is added to your project, it appears in the
Python Environments window, you can activate it like any other
environment, and you can manage its packages. Right-clicking it and
selecting Remove either removes the reference to the environment, or
deletes the environment and all its files on disk (but not the base
interpreter).
to Question 1:
Visual Studio searches the registry to detect global installed python environments by following PEP 514 as described in Install Python interpreters.
to Question 2:
Open the Visual Studio Installer again and change the current installation by selecting only the python interpreters you need (you will find they in the Components tab).

This is the same question as this else but for Python.
The thing is that I've built my own installer package of Python interpreter (I've added modules and extras) and once installed I can't find the way to set the location of my custom Python installation dir in PyCharm IDE, I can't find any option to manually specify the location of python interpreter.
While I don't know if exist that option I'm thinking in other alternative, If maybe the PyCharm IDE takes the original Python path from a registry value then it should be sufficient for set the location, but I don't know if pycharm uses a config file or a reg key to get the python location and where is this value to modify it, I need help.
PS: I'm having the same problem for RubyMine IDE.
For PyCharm, in the IDE go to File -> Settings. In the Project Settings navigation panel, select Project Interpreter and then Python Interpreters, then in the right panel, click on the green plus (+) icon on the top right and select local. Navigate to the python executable you would like to specify as your interpreter.
You can also try this:
click on File
select Settings from the menu
in new Settings window click on Project and then Python interpreter
click on gear icon on the right, then on Add... option
in the Add python interpreter window select System interpreter from the list on the left
pick Python, click apply and you are done
I was having similar problems with PyCharm.
Having installed both Python 2.7 and 3.5 I was only able to find the the "python.exe" file for python 2.7.
I tried reinstalling Python 3.5 and attempting to change the installation path to C:// but it lead to several errors. This is the work around I found for getting 3.5 on PyCharm as an interpreter.
Copy the python 3.5 directory in windows explorer.
Paste it into PyCharms choose local interpreter area.
