I'm using astropy's units and EartLocation to set my observatory location. Hardcoded for now.
However, when I run the code in VScode pylint is bugging me with errors whereas the code runs fine when I run it in PyCharm and IDLE.
Code:
obsy_location = EarthLocation(lat=52.91044*units.deg, lon=5.242664*units.deg, height=0*units.m)
Pylint is slapping me with 3 errors in that one line of code:
E1101:Module 'astropy.units' has no 'deg' member; maybe 'dex'?
E1101:Module 'astropy.units' has no 'm' member; maybe 'g'?
E1101:Module 'astropy.units' has no 'hour' member
Mind you, I am quite the beginner but since neither PyCharm nor IDLE seem to have any problems running this line I wonder what VScode's pylint is doing here. Can someone enlighten me?
I run VScode with the most recent Anaconda interpreter.
Tools like pylint or PyCharm do static code analysis. They often do a good job for most Python code, but they fail in cases where the dynamic nature of Python is used.
In this case, astropy.units executes Python code on import to generate unit objects like deg (representing the unit "degree") or m (representing the unit "meter"). In this sense, it's expected and normal that you see "astropy.units has no member deg" warnings, because the static analysis tool doesn't execute the import, and thus those things don't exist in their analysis. I see the same warnings from PyCharm (which has it's own static analysis, doesn't execute PyLint in the background like in your case).
Now it is always possible to configure static analysis tools to ignore warnings of certain classes. Looking at https://stackoverflow.com/a/39500741/498873 , I'd expect this VS Code config setting to do the trick (but didn't try):
"python.linting.pylintArgs": [
"--extension-pkg-whitelist=astropy.units"
]
Late to the party, but this showed up when I was trying to solve the problem. Adding this to my settings works for me to turn off that pylint warning:
"python.linting.pylintArgs": [
"--ignored-classes=astropy.units"
]

I am a bit fresh to Julia (and stack overflow), so it might be a dummy question. I am using VS code in ubuntu 18.04.
Every time I start Julia REPL from VS code (Ctrl+shift+P, then "Julia: Start REPL"), the Julia REPL starts with a strange command "source /home/$user_name/bin/activate" and then an error (of course source is not defined in Julia) :
ERROR: UndefVarError: source not defined
Stacktrace:
[1] top-level scope
# REPL[1]:1
This problem was shown a couple of weeks ago but it does not affect my code at least for now. I have tried to search the problem but haven't found any similar questions. Any hints on what's going on? Many thanks!
Edit:
I think I might have used Conda somewhere.
Do "which Julia", I got:
/home/$user_name/julia-1.7.2/bin//julia
There is no "/home/$user_name/.julia/config/startup.jl" file, all the directories under "/home/$user_name/.julia/" are as follow:
artifacts compiled dev logs prefs scratchspaces
clones conda environments packages registries
Then I found a "startup.jl" file under "$JULIA_INSTALL_FOLDER\etc\julia\startup.jl", with following content (seems like not helping on my problem).
# This file should contain site-specific commands to be executed on Julia startup;
# Users may store their own personal commands in `~/.julia/config/startup.jl`.
Solved by following #SundarR's suggestion.
The problem was caused by the VSCode-Python extension installed.
Please see the comment above for the details and thanks again!
This is a long post, sorry.
I have been trying to start a project, using Rust, but ran into a problem: it just does not work correctly on Linux in VSCode/Atom.
Wasted 3 days, searching online, trying different tutorials/videos - nothing worked + most of the material is from 2017. I have tried Matrix chat, but no one knew what to do. Git too has no solution as people keep suggesting very random things, like "change this variable in toml file to something else, and back again"
Git: https://github.com/rust-lang/rls-vscode/issues/513
I installed (and re-installed rust many times in the last 3 days), and it works just fine from the terminal, but not in the Editor.
Two Issues:
Editors don't see any crates, so you can't run your code from the editor.
Autocomplete does not work (only works on std, not on extra crates you add).
What I did (out of many other things):
install Rust (on Manjaro and Debian computers): curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
Tried stable, beta, nightly (for racer)
Just did a clean install again:
stable installed - rustc 1.40.0 (73528e339 2019-12-16)
Rust is installed now. Great!
Installed Rust (rls) rust-lang.rust extension in VSCode (and rust in Atom)
Created a new project: cargo new test_proj and added new rand = "0.6" to [dependencies] and used cargo build. It did build rand
Added "rust-client.enableMultiProjectSetup": true to the settings file to avoid a warning: A Cargo.toml file must be at the root of the workspace in order to support all features. Alternatively set rust-client.enableMultiProjectSetup=true in settings. by Rust (rls)
I also install 'code runner' extension that I use with Python, C++, and Java, to run the code from within the editor.
So now I have just the main func and it runs just fine from the editor:
Now I add rand and it seems to work, and does SOME auto-completion...
But now it stops working:
OK, I will finish the code and try running it, And now we can't run it anymore as the crate is missing:
OK, let's try Ctrl + Shift + B and try cargo build:
For some odd reason, it is looking in /media/Work/Work/rust_code and not in /media/Work/Work/rust_code/test_proj/
One last thing: let's try running in the terminal:
So it does work just fine.
Sorry for the long post, but I have wasted 3 days now and it still can't get it up and running. Did anyone manage to set this up at all?
It has to be Atom or VSCode as I have all of the other languages/projects setup there + VSCode is listed on the official Rust website, so I presume it should work.
Basically, out of two editors (VSCode and Atom), that have Debugging capabilities, unlike Intellij Rust, both don't work for me and I just can't code in Rust as tools are literally broken/not mature enough for productive work. Please let me know if I am wrong and it is just a case of one little flag, that everyone forgets to mention, is missing in some config.
Short Version
Assuming I understand the issue correctly. Then the various build issues boil down to different ways you're trying to build the project, and attempting to do so in different directories.
TL;DR: The directory you have open in VSCode is the rust_code directory. Close it and instead open rust_code/test_proj. Now the Rust: cargo build (or Rust: cargo run) should work.
Long Version
Editors don't see any crates, so you can't run your code from the editor.
The Rust: cargo build task isn't working, because the directory you have open isn't a "Rust project" (Cargo package), it's a directory containing another directory, which is a Rust project.
Looking at your screenshot shows this, look at how the top line says rust_code/test_proj:
When you execute the task, Cargo is complaining that rust_code/Cargo.toml doesn't exist, which is true since it's located in rust_code/test_proj/Cargo.toml
If you look at the output of this screenshot, you can see that is the case:
Here you're executing cargo run manually. But the important difference is that you're inside the rust_code/test_proj directory.
Lastly simply executing rustc main.rs is failing since you aren't passing the arguments needed. So rustc doesn't know anything about your dependencies.
Try executing cargo build -v then you can see all the arguments that Cargo is passing to rustc.
Autocomplete does not work (only works on std, not on extra crates you add).
Try and open a directory that contains a Cargo.toml, then code completion should work for dependencies. If I don't, then I get the following notification, and code completion only works for the standard library as you said. That being said, RLS is weird sometimes.
If I had to guess, then I think RLS compiles the code, and at some stage extracts the needed information. Thus if the code doesn't compile, then code completion could be affected. But this is 100% an educated guess.
Alternatively, I have heard praise about using IntelliJ + the Rust plugin, but I haven't used it myself yet.
I have figured out one part: problems with running your code from within the VSCode. I had to modify default code-runner command for rust:
Original command:
"rust": "cd $dir && rustc $fileName && $dir$fileNameWithoutExt",
Changed to:
"rust": "if [ $(basename $dir) = 'examples' ]; then cargo run --example $fileNameWithoutExt; else cargo run; fi",
And now it works, and I can run my code quickly.
Part 2: Autocomplete still is very very bad, unfortunately. I am using RLS. there is this thing racer. Is it a better choice?
Alternatively, I have heard praise about using IntelliJ + the Rust
plugin, but I haven't used it myself yet.
As I mentioned in my previous post, IntelliJ, free edition does not have a debugger from what I can see. I need it.
I am wondering how people get a good autocomplete from Rust?
So I have anaconda installed and make a separate environment for all my projects. Normally I just use PYDEV to create a new interpreter pointing to the anaconda enviornment and load the project in eclipse and all is good. After doing the last one though 95% of the time I go to debug I keep getting the error
An internal error occurred during: "Debug Source Lookup".
java.lang.IllegalArgumentException
The other 5% it kind of works as I can follow one script or a function before it starts breaking.
I've tried reloading the project, interpreter and conda enviornment to no luck. All my past projects which use to work are also now giving the same error.
The funny thing is when I'm in the debug perspective though it does seem to be working (I can see the Variables and use the interactive console to test stuff), but anytime I try to step into, over ect I get the error (even though it does seem to be working). So for the image above I can go through the code fine until it tries to jump to the other file which throws the error, but if I step into it I can manually open that file and walk through the function (just each step throws the error) and still interact with the code which is in the position through the console.
Any ideas how to fix?
Well, it may be something specific to this use-case (for instance, if the code for some object is evaluated and the source code is not really available for the debugger this is actually expected).
Can you provide the full stacktrace from the error log? (see: http://www.pydev.org/faq.html#HowdoIReportaBUG for details on how to get it)
Why do I have the same suggestions while typing expression?
Example:
I had exactly the same problem. After a week or so, it get really annoying.
basically, as the comments hint to, there are probably multiple linting or intelisense tools. In my case (for python) i had the pylance extension added.
When i disabled this, the problem went away, but features were missing. So i added it back...
For some reason (i dont know why), this fixed the problem !!!
I can only hypothesise that in some way the extension was corrupted. Nevertheless, it worked.
EDIT:
I can also confirm that unchecking this setting appears to work:
Jupyter: Pylance Handles Notebooks
My current system is Windows 11, with python 3.10.
Final edit (8 Dec 2022):
This is resolved here:
Please could you install VS Code 1.74 and the latest Jupyter, PyLance and Python extension and confirm this still exists.
Visual Studio Code provides an API so third-party extensions and built-in modules can contribute suggestions for auto-completion pop-ups. The system is currently designed so suggestions are merely appended—there's no duplicate detection or removal (perhaps because extensions can also take care of sorting suggestions and such algorithm would get on the way). That means that if you have more than one extension or module for a given language you can easily get duplicate entries.
Having several extensions for PHP is not necessarily a bad idea since they can address different needs (for instance, PHP DocBlocker just creates annotations, it doesn't provide auto-completion suggestions) but you have at least two extensions (PHP Intelephense and PHP Intellisense) that do exactly the same things. That's likely to hurt performance (all your workspace files will be scanned several times) and just adds noise.
I suggest you read the extension descriptions carefully to learn what they do exactly and then figure out which ones you need. Remember that extensions can be enabled/disabled in a per-workspace basis.
The following is just my own totally subjective opinion. Among the PHP extensions that provide code intelligence only two of them seem mature enough:
PHP Intelephense
PHP Intellisense
I've tried both. PHP Intelephense works best for me than PHP Intellisense so that's the one I've kept. I've also disabled php.suggest.basic following the installation instructions because basic suggestions didn't add any value to me (they were blind string matching):
Turn off the php.suggest.basic setting for best results.
... as well as taming builtin Emmet support, which was providing really dumb suggestions:
"emmet.showExpandedAbbreviation": "inMarkupAndStylesheetFilesOnly"
YMMV.
TLDR; Installing pre-release version of Jupyter solves (v2022.11...)
Ok, so after some more extensive experimentation I think I found what's causing this in my case. After looking at the processes I noticed that there were two Pylance processes running, and consistently this would only be a problem if I was working in a session with a jupyter notebook open or one that had been opened.

Pylance basically spins up a service for the workspace, and then spins up a separate service for the notebook.
Output from "Python Language Server" logs:
Disabling Jupyter removes the duplication, and after installing an earlier version of the extension (v2022.4) this appears to have fully resolved the issue. I'm going to go ahead and log the extension bug once I have something reproducible.
As of 11/30/22, Jupyter Extension Pre-Release version v2022.11.1003281132 is the latest version fixes this issue. Click the gear icon next to the extension and you should see "install another version..." Then you can select version v2022.11.1003281132.
I've been looking in to using Py.Test to automate unit testing in some code I've been working on. I've discovered the following behavior: when a test that I've built has an error (that would otherwise cause the interpreter to barf), the testing framework seems to silently ignore the test altogether.
I'm worried that, as I implement more tests, I'll mistake "this test had an error and didn't run" for "this test passed". Ideally, I'd like to hit a button in Eclipse and have a unit test fail if it has a syntax error in it. Other than "Why don't you write code without syntax errors in it?", is there another solution I'm missing?
Alternatively, is there a way to make Py.Test tell you what test files were found, and which ones were run?
Setup is PyDev 2.7.1 and Eclipse 4.2, with Python 2.7.3 and PyTest 2.3.4.
I think the issue has to do with one of the command line options I set in Preferenced -> PyDev -> PyUnit. I had been running with -n 4, which splits the tests up over processors. This seems to have suppressed the syntax errors. The same option also made debugging not work (i.e., breakpoints were skipped) which seems pretty obvious in hindsight.
