I am using PyCharm to work on a project. The project is opened and configured with an interpreter, and can run successfully. The remote interpreter paths are mapped properly. This seems to be the correct configuration, but PyCharm is highlighting my valid code with "unresolved reference" errors, even for built-in Python functions. Why don't these seem to be detected, even though the code runs? Is there any way to get PyCharm to recognize these correctly?
This specific instance of the problem is with a remote interpreter, but the problem appears on local interpreters as well.
File | Invalidate Caches... and restarting PyCharm helps.
Dmitry's response didn't work for me.
I got mine working by going to Project Interpreters, Selecting the "Paths" tab, and hitting the refresh button in that submenu. It auto-populated with something called "python-skeletons".
edit: screenshot using PyCharm 3.4.1 (it's quite well hidden)
There are many solutions to this, some more convenient than others, and they don't always work.
Here's all you can try, going from 'quick' to 'annoying':
Do File -> Invalidate Caches / Restart and restart PyCharm.
You could also do this after any of the below methods, just to be sure.
First, check which interpreter you're running: Run -> Edit Configurations -> Configuration -> Python Interpreter.
Refresh the paths of your interpreter:
File -> Settings
Project: [name] -> Project Interpreter -> 'Project Interpreter': Gear icon -> More...
Click the 'Show paths' button (bottom one)
Click the 'Refresh' button (bottom one)
Remove the interpreter and add it again:
File -> Settings
Project: [name] -> Project Interpreter -> 'Project Interpreter': Gear icon -> More...
Click the 'Remove' button
Click the 'Add' button and re-add your interpeter
Delete your project preferences
Delete your project's .idea folder
Close and re-open PyCharm
Open your project from scratch
Delete your PyCharm user preferences (but back them up first).
~/.PyCharm50 on Mac
%homepath%/.PyCharm50 on Windows
Switch to another interpreter, then back again to the one you want.
Create a new virtual environment, and switch to that environments' interpreter.
Create a new virtual environment in a new location -- outside of your project folder -- and switch to that environment's interpreter.
Switch to another interpreter altogether; don't switch back.
If you are using Docker, take note:
Make sure you are using pip3 not pip, especially with remote docker and docker-compose interpreters.
Avoid influencing PYTHONPATH. More info here: https://intellij-support.jetbrains.com/hc/en-us/community/posts/115000058690-Module-not-found-in-PyCharm-but-externally-in-Python .
If the above did not work for you, but you did find another trick, then please leave a comment.
In my case it was the directories structure.
My project looks like this:
+---dir_A
+---dir_B
+app
|
\-run.py
So right click on dir_b > "mark directory as" > "project root"
You have to mark your root directory as:
SOURCE ROOT (red),
and your applications:
EXCLUDED ROOT (blue).
Then the unresolved reference will disappear. If you use PyChram pro it do this for you automatically.
I find myself removing and re-adding the remote interpreter to fix this problem when Invalidating Caches or Refreshing Paths does not work.
I use vagrant and every once and awhile if I add a new VM to my multi-vm setup, the forwarded port changes and this seems to confuse PyCharm when it tries to use the wrong port for SSH. Changing the port doesn't seem to help the broken references.
If none of the other solutions work for you, try (backing up) and deleting your ~/.PyCharm40 folder, then reopening PyCharm. This will kill all your preferences as well.
On Mac you want to delete ~/Library/Caches/Pycharm40 and ~/Library/Preferences/PyCharm40.
And on Windows: C:\Users\$USER.PyCharm40.
Tested with PyCharm 4.0.6 (OSX 10.10.3)
following this steps:
Click PyCharm menu.
Select Project Interpreter.
Select Gear icon.
Select More button.
Select Project Interpreter you are in.
Select Directory Tree button.
Select Reload list of paths.
Problem solved!
Sorry to bump this question, however I have an important update to make.
You may also want to revert your project interpreter to to Python 2.7.6 if you're using any other version than that This worked for me on my Ubuntu installation of PyCharm 4.04 professional after none of the other recommendations solved my problem.
Much simpler action:
File > Settings > Project > Project Interpreter
Select "No interpreter" in the "Project interpreter" list
Apply > Set your python interpreter again > Click Apply
Profit - Pycharm is updating skeletons and everything is fine.
If you want to ignore only some "unresolved reference" errors, you can also tell it PyCharm explicitly by placing this in front of your class/method/function:
# noinspection PyUnresolvedReferences
You might try closing Pycharm, deleting the .idea folder from your project, then starting Pycharm again and recreating the project. This worked for me whereas invalidating cache did not.
I finally got this working after none of the proposed solutions worked for me. I was playing with a django rest framework project and was using a virtualenv I had setup with it. I was able to get Pycharm fixed by marking the root folder as the sources root, but then django's server would throw resolve exceptions. So one would work when the other wouldn't and vice versa.
Ultimately I just had to mark the subfolder as the sources root in pycharm. So my structure was like this
-playground
-env
-playground
That second playground folder is the one I had to mark as the sources root for everything to work as expected. That didn't present any issues for my scenario so it was a workable solution.
Just thought I'd share in case someone else can use it.
It could also be a python version issue. I had to pick the right one to make it work.
None of the answers solved my problem.
What did it for me was switching environments and going back to the same environment. File->Settings->Project interpreter
I am using conda environments.
Mine got resolved by checking inherit global site-packages in PyCharm
File -> Settings -> Project Interpreter -> Add Local Interpreter -> Inherit global site-packages
I closed all the other projects and run my required project in isolation in Pycharm. I created a separate virtualenv from pycharm and added all the required modules in it by using pip. I added this virtual environment in project's interpreter. This solved my problem.
Geeze what a nightmare, my amalgamation of different StackOVerflow answers:
Switch to local interpreter /usr/bin/pythonX.X and apply
View paths like above answer
Find skeletons path. Mine was (/home/tim/Desktop/pycharm-community-2016.2.3/helpers/python-skeletons)
Switch back to virt interpreter and add the skeletons path manually if it didn't automatically show up.
None of the above solutions worked for me!
If you are using virtual environment for your project make sure to apply the python.exe file that is inside your virtual environment directory as interpreter for the project (Alt + Ctrl + Shift + S)
this solved the issue for me.
In my case the inspection error shows up due to a very specific case of python code.
A min function that contains two numpy functions and two list accesses makes my code inspection give this kind of errors.
Removing the 'd=0' line in the following example gives an unresolved reference error as expected, but readding doesn't make the error go away for the code inspector. I can still execute the code without problems afterwards.
import numpy as np
def strange(S, T, U, V):
d = 0
print min(np.abs(S[d]), np.abs(T[d]), U[d], V[d])
Clearing caches and reloading list of paths doesn't work. Only altering the code with one of the following example patches does work:
Another ordering of the 'min' parameters: schematically S U T V but not S T U V or T S U V
Using a method instead of the function: S[d].abs() instead of np.abs(S[d])
Using the built-in abs() function
Adding a number to a parameter of choice: U[d] + 0.
My problem is that Flask-WTF is not resolved by PyCharm. I have tried to re-install and then install or Invalidate Cache and Restart PyCharm, but it's still not working.
Then I came up with this solution and it works perfectly for me.
Open Project Interpreter by Ctrl+Alt+S (Windows) and then click Install (+) a new packgage.
Type the package which is not resolved by PyCharm and then click Install Package. Then click OK.
Now, you'll see your library has been resolved.
In PyCharm 2020.1.4 (Community Edition) on Windows 10 10.0. Under Settings in PyCharm: File > Settings > Project Structure
I made two changes in Project Structure:
main folder marked as source and
odoo folder with all applications I excluded
Screenshot shows what I did.
After that I restarted PyCharm: File > Invalidate Caches / Restart...
Unresolved references error was removed
Invalidating the cache as suggested by other answers did not work for me. What I found to be the problem in my case was that PyCharm was marking init.py files of Python packages as text and thus not including them in the analysis which means python resolving was not working correctly.
The solution for me was to:
Open PyCharm settings
Navigate to Editor -> File Types
Find Python and add __init__.py to the list of python files
or Find Text and delete __init__.py from the list of text files
To add yet another one: None of the solutions involving the Python Interpreter tab helped, however, I noticed I had to set Project Dependencies: In the project that had unresolved reference errors, none of the dependencies were checked. Once I checked them, the relevant errors disappeared. I don't know why some are checked to begin with and others are not.
If you are using vagrant the error can be caused by wrong python interpreter.
In our vagrant we are using pyenv so I had to change Python Interpreter path path from /usr/bin/python to /home/vagrant/.pyenv/versions/vagrant/bin/python
I have a project where one file in src/ imports another file in the same directory. To get PyCharm to recognize I had to to go to File > Settings > Project > Project Structure > select src folder and click "Mark as: Sources"
From https://www.jetbrains.com/help/pycharm/configuring-folders-within-a-content-root.html
Source roots contain the actual source files and resources. PyCharm uses the source roots as the starting point for resolving imports
I had to go to File->Invalidate Caches/Restart, reboot Ubuntu 18.04 LTS, then open Pycharm and File-> Invalidate Caches/Restart again before it cleared up.
For me it helped:
update your main directory "mark Directory as" -> "source root"
#kelorek works for me, but before, in interpereter paths I had to add some path.
lets say
from geometry_msgs.msg import Twist
is underline as error, then in remote machine in python run:
help("geometry_msgs")
at the end there will be path lets say :
/opt/ros/foxy/lib/python3.8/site-packages/geometry_msgs/__init__.py
so to Your intepreter pycharm path add
/opt/ros/foxy/lib/python3.8/site-packages
Hope it will help You and it helps me :)
I had the same symptoms. In my instance the problem source was that I had set
idea.max.intellisense.filesize=50 in the custom properties.
I could resolve it by setting it to 100.
Help->Edit Custom Properties
I've installed Python 3.5.1 as default in Win7(x64) for all my projects in Python.
I use PyCharm 5.0.5 community edition for develop Python scripts and its default settings has "Default Project Interpreter" as "3.5.1 (C:\Python35\python.exe)"
At my work we are migrating from MS Office 2007/2010 to LibreOffice-5. I wrote some macros in VBA, despite of I'm not a VB enthusiastic. Basic lacks good data structures, such as lists (I love list comprehensions), dictionaries, sets and tuples. So, I want to rewrite the VBA macros in LibreOffice-5 Python script macros.
LibreOffice-5 installation has its own embebed Python at "C:\Program Files (x86)\LibreOffice 5\program", version 3.3.5. Scripts of Python in LibreOffice-5 installation is at :
Libre Office Macros; "C:\Program Files (x86)\LibreOffice 5\share\Scripts\python"
My Macros; "C:\Users\trimax\AppData\Roaming\LibreOffice\4\user\Scripts\python"
The question is simple:
I need configure PyCharm settings to develop the python scripts of LibreOffice macros with the embebed python version. I don't know if I need to set a virtual environment or if I can just to set the Project Interpreter.
By the way, are there any method to insert macros in the document, to share it with the document, as the VBA Project Modules?
From the PyCharm documentation, it sounds like you could use a virtual environment to target LibreOffice (likely Python 3) and OpenOffice (likely Python 2) in two different projects. Otherwise it looks like a local interpreter is enough.
To test PyCharm, I did the following:
Download PyCharm and create a new project.
It asks which interpreter to use. Click on the gear icon and specify Add Local. Browse to C:\Program Files (x86)\LibreOffice 5\program\python.exe.
Create a new python file.
Then add this code:
import uno
from com.sun.star.awt import Point
p = Point(2,3)
print(p.X)
points = uno.Any("[]com.sun.star.awt.Point", (p,))
print(repr(points))
It underlined the com import statement, although it's not actually an error. PyCharm did recognize the other statements such as uno.Any.
To run, go to Run -> Run. It ran successfully and printed results as expected.
Instead of an IDE, I typically just use a text editor. From what I have seen, a lot of the IDE tools (syntax highlighting, auto completion, debugging) do not work very well with UNO anyway. It is better with Java, but that is a different topic.
By the way, are there any method to insert macros in the document, to share it with the document [...]?
To embed Python code into a document, unzip the .odt file and follow the instructions here.
To embed Python code into a documents, I recommend using the APSO extension. You can download the LibreOffice extension here. It creates a new menu item: Tools...Macros...Organize Python Scripts. From there you can embed or export files.
Ok, so I'm looking to switch to PyCharm from PyScripter for OS independent development. I also wanted to mention that I'm using Perforce for version control.
So what I currently do is double click a .py for editing in Perforce, and PyScripter opens up and I edit to my hearts desire. I can click on an imported function, and it'll open up the corresponding .py file and bring me right to the function. Awesome.
So I have yet to be able to achieve that on PyCharm. I'm using the community version which should be just fine for what I want, which is just an editor with some python checking & built in console.
When I set the default .py program to use in Perforce to PyCharm, I click on the .py and PyCharm fires up. Good so far. But my problem arises when I try to "ctrl + click" a function or method. I get the "Cannot find declaration to go to." I import the associated class & file.
(Just an example, not actual code). So in Transportation.py I have "import Cars", which is a .py. I do Cars.NumberOfDoors() and I get the above error. My folder structure is:
Scripts (folder)
Population.py (General support script)
Citybudget.py (General support script)
MassTransit (folder)
Transportation.py
Cars.py
So question boils down to, is how do I properly setup the root to be the Scripts folder when I click on a file from Perforce? How do I set it up that it recognizes where it's at in the folder structure? So if I'm in the MassTransit it'll set the root as Scripts folder, and same for if I'm accessing the general support scripts like Population.py?
Go to
File --> Open
in Pycharm and select your Scripts(folder) and open it. Then the Pycharm will treat it as a project and you will be able to ctrl + click a function.
Does auto-completion for the Panda3d library working with PyCharm? It seems PyCharm cannot automatically create the Python skeletons for this library. I would also be happy if I could at least manually define those stubs in PyCharm.
Any ideas how to tell PyCharm what Python modules and classes are there in a "binary" library?
For me it worked just selecting in Settings > Project Interpreter the panda python interpreter (python.exe, not ppython.exe.).
If you wanna use ppython.exe you have to rename to something starting with "python" like pythonpanda.exe, since Pycharm only considers an interpreter something that starts with "python". Anyway, ppython and python are supposed to be the same.
EDIT
Another thing that can make it work, is using another python interpreter (the standard, virtualenv, whatever) and placing a path file in a folder within the PYTHONPATH.
In other words:
Create a text file named panda3d.pth
Write two lines
path\to\pandafolder
path\to\pandafolder\bin
Save it in the site-packages of your python interpreter
Configure Pycharm to use this interpreter
I am trying to use sublime to write code, I want to know how to configure sublime so it can do auto-complete as eclipse does?
I have installed PyQt4, and it's ok if I use eclipse,
if I write the following code:
from PyQt4. After I input the dot, a list of possible matches will show in a drop-down list?
how can I do this with sublimerope?
I am using mac. Which configuration needs changed?
The solution here
http://messymind.net/2012/07/why-you-should-use-sublime-text-2/
worked for me:
Go to your new .ropeproject folder in your project and edit the config.py. Find the section that looks like this:
?
#You can extend python path for looking up modules
#prefs.add('python_path', '~/python/')
Here you can add the sources to your site-packages and your current open project, e.g.:
?
prefs.add('python_path', '/path/to/site-packages')
prefs.add('python_path', '/path/to/your/project')
