r/learnpython on Reddit: Why is python (and vscode's terminal) unbelievably slower than doing so directly from cm? This is not a problem on mac for some reason too

July 4, 2024 -

More particularly, python is only excruciatingly slow when ran in vscode's terminal for some reason, also vscode's terminal boots up very slowly too, but when python code is ran with
python main.py

it only takes a fraction of a second to finish the code. Also worth mentioning is that on mac, vscode terminal is completely normal and quick

For context: hello world takes around 5 seconds on my machine to execute, but takes a fraction of a second when ran directly from cmd, not vscode

Why is this happening? Is it possible to optimise vscode for faster python running time?

This sounds like a VSCode issue for (whatever non Mac computer you’re using) if the terminal itself takes a while to load. It’s not a python issue. So you should go to the VSCode communities and seek help there. FWIW it shouldn’t be like this, I use VSCode on macOS and windows with no issues. It’s something in your windows terminal startup and/or VSCode that’s causing this.

Some of it might be all the additional tools vscode runs for example the debugging server, profiling, any runtime extensions, parsing launch.json and applying it etc. There is a lot stuff (overhead) going on when you click the little play button or press F5 vs running python directly. Even if you aren’t using the extra tooling VSCode still may have to run through a long preflight check to see if it SHOULD be doing something for you.

r/vscode - Python extension slow to load

December 2, 2020 -

Recently updated my laptop, and after installing VS Code and Python on the new machine, I've noticed that the Python extension takes forever to load any time VS Code is (re)started. I haven't timed it exactly, but probably at least a minute or more, just to load an extension on a 'gaming' laptop with oodles (technical term!) of RAM, disk space, and processor power to spare.

Nothing particularly exotic as far as extensions loaded - Python (obviously), Pylance, Jupyter, Remote - WSL, Vim, Visual Studio Intellicode and vs-code icons. Even with everything disabled but Python, Pylance and Jupyter, it doesn't change - and the extension very obviously holding things up is the Python one.

Nothing too exotic about the Python install... vanilla 3.8.6, from python.org, using virtualenvs for development. Even with the base install, and nothing much beyond pylint, black and virtualenvwrapper-win installed via pip... this seems really, really, really odd.

Any ideas?

Turns out vs-code icons is slow as heck on startup, you can see for yourself using CTRl+Shift+P: Developer: Startup performance. But the Python extension definitely gives me trouble too.

r/vscode on Reddit: Running python code takes forever

October 4, 2024 -

I was just doing my stuff in vsc and at some point running my python scripts started taking whole 3 seconds for no reason, it was always instant to run, but now there is that delay that shouldn't be a thing. I'm not using any antiviruses or extensions, I can't see why did that problem occur out of nowhere, anyone has any ideas?

If your code runs from terminal instantly, but not from shortcuts (i.e. the "Run" button): Try downgrading the VS Code Python extension to 14.1. 16.0 seems to be slow.

FIX: I fixed it! turns out i didn't completely remove vscode from my pc, so i deleted the config and cache folders and reinstalled vscode and it works perfectly now! still curious as to what the hell caused it...

at the bottom left of vscode it keeps saying "Python extension loading" and it never finishes, i tried reinstalling all the extensions, updating vscode, rebooting the system, and disabling the other extensions one by one, but to no avail.

it was working fine before, any help would be appreciated!

EDIT: im using linux (kubuntu 20.04) and i can't do anything python related (run scripts, formatters not working...etc)

I too ran into this today. None of the log files under '~/.config/Code/' give any indication as to what was going on with the extension. I eventually hit the "Do I really have to un/reinstall?!" I'm using Pop!_OS: From Pop_Shop I went to uninstall it, and was met with an error message that vscode didn't exist to uninstall. (weird). Nonetheless, after it failed it gave me the option to install vscode again. *click* Install. Nothing happened other than the option to install toggled back to uninstall. Now VS code is working, and I didn't have to re-add all my extensions. I did get an update for vscode just the other day -- could be related.

Improving load times and performance of Python Extension for VS Code with WebPack | by Don Thilaka Jayamanne | Medium

December 3, 2018 - Since the September/October release of VS Code, a number of issues were filed on our GitHub repo with complaints about the Python extension slowing down VS Code, more specifically users would file issues with the following information: ... Within a few days we realized we had a problem on our hands. To understand how one extension would slow down VS Code, one needs to realize the fact that all extensions in VS Code are loaded into the same process.

Please update the python extension to the latest version

or install the pre-release version directly. ( may be more useful to you )

this will basically solve your problem.

If the error continues, follow these steps:

Uninstall Python extension (if you have pylance uninstall it first). Uninstall any other extension that is failing.

Close all instances of VS Code.

Go to, %USERPROFILE%/.vscode/extensions (on windows) or ~/.vscode/extensions on Linux/Mac.

Delete any folder with the name starting with ms-python.python*

Start VS Code, and install Python extension (also pylance if you uninstalled it in step 1).

I was having this issue and tried the above answer and it still didn't work. It turns out I hadn't installed python on my system yet. I didn't realize because I normally use it remotely.

From the VSCode documentation:

Quick start

Step 1. Install a supported version of Python on your system (note: that the system install of Python on macOS is not supported).

Step 2. Install the Python extension for Visual Studio Code.

Step 3. Open or create a Python file and start coding!

r/vscode on Reddit: Issues Loading Python Extension

September 2, 2020 -

I'm starting to mess around with python again in my free time and I'm having issues with the python extension. I only have 3 extensions installed. C#, PowerShell, & Python. All from Microsoft. I've uninstalled/reinstalled VS Code. I'm running 3.8.5 python.

When I try to add python (control + shift + p) it spins at loading the extension and comes back with reload, wait, or cancel. If you hit wait afew times, it will eventually load the python extension. The machine is an i7 4xxx, 32 gb of ram, ssd, ect.... I'm seeing no CPU, RAM, or Disk spikes during this time.

Has anyone seen anything like this before? Is there anything in the event viewer log that would help?

*** EDIT ***
I also tried it with the other extensions disabled.

You can look into the OUTPUT panel, and choose these channels in the right drop-down list to get some helpful information: 'Python', 'Python Language Server', 'Extensions', 'Log(Shared)', 'Log(Extension Host)'. And click Help -- > Toggle Developer Tools --> Console Panel to get more information.

r/vscode on Reddit: VSCode running super slow suddenly

January 20, 2020 -

So Basically ive had Vscode installed for a long time but recently it started running really slow.

here are some of the problems ive been having:

Every time i open a file it takes like over 10 seconds for it to open in vscode.
When i launch vscode, it shows up invisible then after 30 seconds i see the actual app.
When i look at extensions the details for them take 30 seconds to load in.

ive tried:

completley uninstalling and reinstalling vscode.
deleting all extensions.
restarting pc.
nothing is working.

extensions installed:

VSCode Discord RPC
Visual Studio IntelliCode
Python
Material Icon Theme
Material Theme
Java Extension Pack which includes:

Language Support for Java by red hat
Debbugger for Java
Java test runner
Maven for java
Java dependecy viewer

If you go to Help > Toggle Developer Tools, do you see any extension errors? I've had quite a few issues with the python extension that prevented extensions from being listed, among other things that sound similar to your experience.

I know that if I uninstall vscode from my Linux (Fedora) machine some folders are not removed, the one containing my settings for example, so when I reinstall it will use those exisiting settings. Maybe try renaming that folder and let vscode create it from scratch again, see if there is any difference.
