I have searched for the problem on the site, but could not find the case or a similar one. This one I checked also as the best matching
tihs one.
I am using the system interpreter, Python (v3.7.0), and I can access all the packages in the python IDE no import error or something like that. In fact, when I use PyCharm and try to use import statement in the script, it shows 'No module named ', and when I run the script on PyCharm or from a different source it works with no error. In other words, I have a problem only in IDE, and since PyCharm IDE shows an error that there is no module when I am scripting, I cannot use the PyCharm IDE things associated with that module such as auto-complete. Yet, when I run the script from any shell or IDE they all successfully run the codes.
I don't figure out what is wrong, but I will provided some images below.
I have been using PyCharm for the projects, lately I've probably done sth wrong, but not sure so that PyCharms throws an error in IDE while scripting. The thing is while scripting when I use import statement PyCharm does not recognize the module which is already installed.
I don't figure out what is wrong, but I will provided some images below.

Did you checked the Project Interpreter? If the interpreter you are using is different from IDLE, this might happens. Go to Preference -> Project Interpreter, and check the interpreter you are using it now. You can also check the packages that are currently being installed right away.

What I get when I try to run it
Nothing I'm trying to import is being recognized by the IDE. I do have to admit, I am a fairly novice programmer, and the process of successfully importing external modules (, the ones that don't come with python,) is very confusing to me right now. But from everything I could scrap online, it seems like for VS 2022 I first have to go to [TOOLS] > [PYTHON] > [PYTHON ENVIRONMENTS]. Then from the environments popout I select my python version (, which is 3.10 (64-bit),) update my pip if not already up to date, search for my desired package and download. The terminal said the download completed but the IDE still can't find the import.
My installed packages in my python environment
This is a problem I've been putting off for months, and in the past I downloaded the packages through the Windows command prompt instead of the IDE. I'm not sure if it's any different, I'm not sure if one is more right. The result was the same regardless, it didn't work. And after several uninstalls and reinstalls, I even tried moving the entire package folder into my project folder to see if anything would change. The import was accepted but something in the packaged errored out. Moving files like that doesn't seem like the correct way anyway, I just want to make sure I bring up everything I tried to fix this.
I suspect that solution is something super simple that I'm just overlooking or don't know. I still kind of think the package needs to be with my .py file in some way but I'm unsure. If you can save me I'd appreciate it because I've been stumped for a while now.
I know my code is super simple, but I just wanted to show the error. I get the error before it prints.
I'm using the PyCharm (Python plugin) on IntelliJ Ultimate.
Normally the IDE highlights any undefined identifiers with a red-underline, but I've noticed that on some projects this feature stops working.
Red-underlines are really useful because they allow me to use IntelliJ's auto-fixes (e.g. importing or creating a missing function/class).
Just about every other PyCharm feature I can think of seems to still be working. For example, AutoComplete works just fine.
Sometimes if I set the project's SDK to , and then set it back to the correct Python interpreter the project starts to highlight NameErrors correctly. This doesn't seem to work consistently. I'm using Conda, and I've tried setting up Conda envs as normal virtualenvs, or as "system interpreters".
I've searched the log files and cannot see anything that might indicate the plugin failed to initialize.
In most cases (except for when the system briefly decides to work), I get no red underlines but all of the other PyCharm features seem to work normally. Furthermore, this only seems to affect Python: Scala and Java code behaves exactly as you might expect it to work in IntelliJ.
Is there a way to debug this? What's going wrong? How do I fix it?
I've had this same problem with the symptons you describe. From the description the cause is that you have "Reader Mode" enabled.
Normally the IDE highlights any undefined identifiers with a red-underline, but I've noticed that on some projects this feature stops working.
The red underline/scribble for errors is suppressed for modules that are currently installed in the projects virtual environment or interpreter. (This makes sense because if for some reason you want to read code from an installed library it's usually not your concern if the library author made mistakes or if that library code for example issues warnings according to your code style settings, etc...)
Sometimes if I set the project's SDK to , and then set it back to the correct Python interpreter the project starts to highlight NameErrors correctly.
If you change the project SDK to an interpreter that does not have your modules installed the errors will be shown again. You can set the display of errors with Reader Mode enabled checking the option at File > Settings > Editor > Reader Mode > Error and warning highlighting, inspection widget. As shown in the screenshot
If you disable Reader Mode the IDE will also again issues errors as usual.
everyone. I've been using python for a while with PyCharm, however I decided to go back on VsCode because I'm used to it.
I installed the python extension, specified the interpreter and compiled a basic file. Everything seems ok, except a strange path in the terminal which is annoying.
When I compile JavaScript it specifies the path rather simple:
C:\Program Files\nodejs\node.exe tests.js
However when I compile python it is a lot bigger:
PS D:\Projects\> ${env:DEBUGPY_LAUNCHER_PORT}='12345'; & 'C:\Users\user1\AppData\Local\Programs\Python
\Python38-32\python.exe' 'c:\Users\user1\.vscode\extensions\ms-python.python-2020.4.76186\pythonFiles
\lib\python\debugpy\no_wheels\debugpy\launcher' 'd:\Projects\app.py'
My question is, is this normal and is there a way to remove it or should I get comfortable with.
Two things. One, that's not compiling your code, it's running your code under the the debugger. Python doesn't really have a compiler step in the traditional sense.
Two, there isn't anything you can do about it. It's how the debugger launches.
I just have a quick question about an error I've been getting when I try to import:
from psychopy import gui
So if I try to import this code in one program I have no problems, however, if I try to import it in another I get:
"ImportError: cannot import name gui"
Does anyone know why this might be happening? Why does it work for one problem, but not the other? Also, I feel like it wasn't doing this before, and it just started suddenly. Any advice would be greatly appreciated.
UPDATE: I think Jon's answer is the correct one. If I was right, you should get an error "no module named psychopy".
Given that you tagged this question with the psychopy tag, my guess is that it works if you run it from the psychopy app and that it doesn't work if you run it from another editor or command line.
The reason is that psychopy is currently shipped as a bundle that comes with it's own python and a lot of modules/dependencies, including psychopy. The system is not made aware of these modules via the PYTHONPATH.
You can make them available system-wide by either (1) following the steps outlined here or (2) use the conda based installation described in this post in the psychopy-dev list. The latter feature is still work in progress but will probably eventually mature to be the default install option.
I think the other answers are wrong ;-)
I think if you had a different virtual environment or installation then the error in your code would indicate "No module named psychopy"
The fact that it finds something called psychopy but no sub-module called gui is a different problem. Often this occurs if you have a folder or file called psychopy next to you current working directory (eg. next to where you launch the script). Then Python thinks that's the psychopy module but can't find gui within it.
So, do you have a folder called psychopy? Rename it psychopyStuff.
I think you are using different virtual environments for both the projects, and so the package is installed in one virtualenv, and not in the other.
To verify this is the case, do a pip freeze in both the projects and compare the results.
If there is a single environment, the output will be same, otherwise the outputs will be different amongst the two.
I use eclipse as my IDE for python. Recently I encountered a strange problem.
A file contains an import from external libraries (such as wx, matplotlib etc.) if I put it inside the src directory, it will run as expected, but in the editor, I get error marks all over the places where I use the imported libraries. The errors say things like "Undefined variable from import".
If I put it in top level of the project, the error marks disappear.
I have added a screenshot of the configuration. I have a feeling that the source of the problem is there, but do not know what to do.
In my installation I have several other libraries in the system pythonpath dialog including wx. Try setting the interpreter again in order to reload the libraries or load them manually.
