I have started using VS Code for work instead of Anaconda and there are some weird observations which I am not able to figure out.
If I try to execute some code in a cell in the interactive window, many-a-times, only output remains available and the input code automatically gets hidden. For eg. I type the following and execute:-
And this is what I see at the window:-
Similarly, there are some variables which I have already defined but they don't show up in the Jupyer:Variables tab. For eg. there is a variable _link_name_to_index which is not visible in the tab as shown below:-
However, when I execute the same in the window, I can see the values of the dictionary as expected:-
Maybe it is just a matter of some settings, but I still couldn't find out which one. Also, I know I have put a lot of images, because it is not a code doubt as such, rather more of a tool doubt. I have taken only one particular example here, but I face this issue often. I am using VS Code version 1.75.0 in Ubuntu 20.04, using Python 3.9.12 in a virtual environment, if it helps.
This is a bug in the latest Version of VSCode (1.75). It is tracked in this issue. For now, the only option seems to be downgrading to v1.74.x

I have been working with Dash and Plotly for Python for quite a while now. Everything was working (in fact, it still does). The problem is I opened VS Code this morning and I have a bunch of highlighted errors on all my .py files. They all show an error like this:
Argument of type "list[dict[str, Any]]" cannot be assigned to parameter "options" of type "_UNDEFINED" in function "init"
"list[dict[str, Any]]" is incompatible with "_UNDEFINED"
This was not here when I last worked on this project (about two days ago). I can still run the web app and it works as expected, but it is really hard to keep working when I have all this highlighted text for apparently no reason.

Does anyone know why this could have happened overnight, and how to fix it?
It looks like you have inadvertently switched type checking on.
In VSC, hover over the curly braces next to 'Python' that appears in the footer at the bottom of the application window to toggle it on and off.
Seems like that you haven't choosen the Python interpreter in your IDE. Select it from the setting of your IDE.
I am using Python 3.8. I have a file test.py. If I change any code in it then it shows output as it’s previous code. I think it recalls the previous memory. How to get rid of it ? I think I have to clear all memory before every Run. I restarted the computer but couldn’t solve this problem.
If you use Spyder IDE, you may choose "Preferences" in "Tools" columns, then click on the "Remove all variables before execution" in "Run".
So originally i thought it only affected changes to my plots but no changes to my code are applied even after saving the *.py file.
After updating to Spyder 3.2.8 the problem still persists.
I found a workaround by restarting the kernel and then rerunning the code so i don't have to close and reopen spyder every time at least.
The problem with this solution is that all my variables are deleted ofc. I found a solution to my problem here
Spyder IDE reload code with run selection ('F9')
and here IPython 3.2.1 documentation.
But when i enter the the first command in ipthyon it tells me it's already activated and after that neither %autoreload nor %autoreload 2 seem to have an effect.
As an example for my problem you can basically take the code example at the IPython 3.2.1 documentation link. For me it wouldn't update from 42 to 43 but still stay at 42.
Another thing is it seems to adopt the first changes i do. I start Spyder run my code everything is fine. I then change something in a *.py file like changing the name of an axis label in a plot. If i run the whole code again or just the changed function with the IPython console it works and integrates the change accordingly. But after that no changes are updated anymore.
I have been using Pycharm for years and have never had any problem. However, after my most recent PyCharm update I can no longer configure the interpreter.
Also each time I create a new project it creates a vent directory under my project. When I go to File/Default Settings/Project Interpreter, I am provided with new options.
In this window it allows you to configure a virtual environment, the conda environment, and the system interpreter. I am assuming that I should configure the system interpreter. From there I point PyCharm to the interpreter on my Mac at /usr/local/Cellar/python3/3.6.3/bin/python3 and hit OK.
It then takes me back to the main window where it shows the path in the project interpreter. At this point I hit apply and get a message:
Cannot Save Settings please use a different SDK name
It doesn't matter which interpreter I choose, I get the same message. Has anyone else come up with the same problem and how do I fix this?
Interestingly my old projects still work correctly.
I had the same problem while setting up the virtual environment for my project and no matter if I create a new virtual environment or select an existing one, I get the warning:
"Cannot Save Settings please use a different SDK name"
Finally I found the solution:
Click on the project interpreter dropdown and select show all.... There you might be having multiple virtual environments with same name. Now here is the conflict you need to fix manually by renaming them so every item has the unique name.
I ran into this issue when trying to get docker up and running with Pycharm 2018.1 and using the container's Interpreter. I would get the error below.
"Cannot Save Settings please use a different SDK name"
The issue I had was due to having multiple python interpreters of the same name.
Under Pycharm || Preferences || Project Interpreter
Click "show all" within the Project Interpreter dropdown and then delete any / all interpreters that you don't need.
How fix this in Windows 10:
close Pycharm .
delete this file: C:\Users\<username>\.PyCharmCE2018.3\config\options\jdk.table.xml
open Pycahrm again and load all python interceptors again.
Jon; I too noticed the difference in the latest version of PyCharm. It seems that it now has an affinity for the latest tool 'venv'. When you create an interpreter - that is what you get.
You can still create a virtualenv manually and point it there instead. I haven't looked into pointing it to a base python-bin because (frankly) you shouldn't generally do it.
My advice (and my proposed answer) is to embrace the change and let it create a 'venv' for you. From there, do all of your installs by "alt-F12". That will open a console with your virtual environment activate -- so your PIP installs into the virtual environment.
Once I began using virtual environments, I never looked back. It has made life much easier in the python world. Pycharm seems to know this as well and is trying to really encourage you to do the right thing.

This may be a known issue of PyCharm and using the method of the accepted answer may not resolve it. Please see https://youtrack.jetbrains.com/issue/PY-27251.
You can close Pycharm and remove jdk.table.xml file from ~/Library/Preferences/.PyCharm2018.1/options directory (Mac version), then start PyCharm again.
Warning: By doing this, all your existing setup of python interpreters will be erased and you need to re-setup them again.
I had same error:
I deleted all invalid project interpreters ( they are red)
then I did https://stackoverflow.com/a/60583928/3842788
You cannot have 2 or more virtual environments with same name. Even if you have projects with same name stored at 2 different places, please give unique name to its venv. This will solve your problem.
To check all the virtual environments:
Go to File >> Settings >> Project: your_project_name >> Project Interpreter
And rename the venv name.
Go to Project > Project Interpreter > Select the dropdown menu > "Show All".
For me, there were several Python environments, two of which were red with an tag. Remove the envs that are red / have an tag, select the remaining valid one, and re-apply settings.
In my case, I moved my project to a different location and PyCharm started complaining about Cannot Save Settings please use a different SDK name. At the top of the main editor, it asks me to Configure Project Interpreter. I clicked it, and then ...
My solution
Remove all existing interpreters that are marked as invalid in the preference.
Select the interpreter in the moved venv subfolder in my project.
Without doing both, I kept getting the same "SDK name" error. It seemed that the project thinks that it already has an interpreter called "python.exe", if you don't actively remove all "invalid" ones.
I solved this issue by cleaning the Pycharm memory cache
Response times in a PyCharm Python Console are unbearably slow when the console is configured to use IPython. This wasn't the case in a previous installation. When the Python Console is not configured to use IPython, and uses IDLE, it performs normally.
The poor response time seems to be linked to the REPL response function, as depicted in the image below. When the REPL response dialog completes, a background process continues to run for several minutes.
Since this was not a problem in a previous installation, the issue must be a result of a configuration change. However, the only thing I changed was to utilize a Conda env instead of a virtualenv.
Any ideas?
This issue was reported to JetBrains. The issue was duplicated and identified as a bug. The status of the issue can be viewed at:
https://youtrack.jetbrains.com/issue/PY-24880
Here is how to apply the "answer" found in the JetBrains bug filed by #vlmercado https://youtrack.jetbrains.com/issue/PY-24880:
Disable auto popup completions (in Editor->General->Code Completions)
Posting my comment as an answer, I have tried it now for a few days and had 0 REPL hangups.
Ubuntu but should work on every machine.
Go to: File----> Settings---->Editor---->General---->Code Completion
Uncheck Rank completion suggestions based on Machine Learning
That's it. Happy Coding.
Today I had the same problem in Pycharm2019.3 with Python3.8. It may have been caused by using miniconda instead of the full anaconda installation, because after installing the ipython package (with -conda install ipython) the long REPL waiting times have dissappeared.
I am not sure if it is solved by jetbrains, for me, it just randomly starts even after 1-2 hrs of coding,
I have tried every options found in Jet brains as well as Stack Overflow like checking and unchecking of 1,2 in combination as shown in image. Have experienced same with the code completion option as well,
These options might help:
Settings: File > Settings > Build, Execution, Deployment > Console
Ipython Setting option:
Run with Console option:
