Here in VSCode whenever I write the following line from . import dispatcher pylint always gives error statement saying Attempted relative import beyond top-level package.
But when I run the module using this command: python -m src.train the program runs without flashing any error. Here is the screenshot from the VSCode editor:
Does someone know who to solve this thing in VSCode?
Just add an empty __init__.py file of the folder that contains your dispatcher.py file, then all the .py files under the folder, as whole, should be recognized as a package. And the lint error should dismiss.

I've imported a module called "github.com/lib/pq". before I ran my code, I inserted this in the terminal % go get github.com/lib/pq. Then when i tried to run my code, I'm getting an error message in the terminal
'no required module provides package github.com/lib/pq: go.mod file not found in current directory or any parent directory; see 'go help modules'
Running go mod tidy will sync your go.mod and go.sum file with the imports in your code, this will add missing dependencies and remove unnecessary ones. Should solve your issue.
I am having trouble installing a module I created in Julia. I am running the Julia plugin under Visual Studio Code. If I run the file below with Ctrl+F5 I get a message
ERROR: LoadError: ArgumentError: Package Utils not found in current path:
- Run `import Pkg; Pkg.add("Utils")` to install the Utils package.
This is the file:
module demo
using Utils
greet() = print("Hello World!")
end # module
If I follow the advice on the error message I get another error message:
ERROR: LoadError: The following package names could not be resolved:
* Utils (not found in project, manifest or registry)
I also tried inserting this line:
import Pkg; Pkg.add(path="C:/Dropbox/Code/Julia/demo/src/Utils.jl")
and got this message (although the path definitely exists):
ERROR: LoadError: Path `C:/Dropbox/Code/Julia/demo/src/Utils.jl` does not exist.
The files demo.jl and Utils.jl are in C:\Dropbox\Code\Julia\demo\src\ and the demo project has been activated as can be seen in the REPL. The OS is Windows 10 Pro.
Any help will be greatly appreciated. Lots of time wasted trying to make this work.
Module and packages are not the same things. In short, packages are modules plus a set of metadata that make it easy for the package to be found and interact well with other packages. See here for a tutorial to write Julia packages:
https://syl1.gitbook.io/julia-language-a-concise-tutorial/language-core/11-developing-julia-packages
In your case, if you want to load a local module, just type include("fileWhereThereIsTheModule.jl") followed by a using Main.MyModule or using .MyModule. Note the dot... without it, Julia would indeed look for a package and to let it find your Demo or Util module you would have to either change an environmental variable or place your module file in certain predefined folders. Using include followed by the "absolute or relative position" of the module you don't have to do either.
I'm trying to get started with what should be a very simple Solidity contract but VSCode is giving me a hard time.
I'm using Juan Blancos solidity plugin but VSCode cannot find openzepplin imports
import "#openzeppelin/contracts/token/ERC20/ERC20.sol";
The error is:
Source "#openzeppelin/contracts/token/ERC20/ERC20.sol" not found: File import callback not supported
Even though vscode shows red squigglies I can compile successfully via hardhat compile.
If I change the path to
import "../node_modules/#openzeppelin/contracts/token/ERC20/ERC20.sol";
VScode stops complaining but then I cannot compile via hardhard, with the error being:
Source "node_modules/#openzeppelin/contracts/security/Pausable.sol" not found: File outside of allowed directories.
My VSCode settings for Solidity extension for both User and Workspace are:
"solidity.packageDefaultDependenciesContractsDirectory": "contracts",
"solidity.packageDefaultDependenciesDirectory": "node_modules"
Which corresponds to my project structure
root
|_ contracts
|_ MyToken.sol
|_ node_modules
|_ #openzepplin
I followed the instructions here and have done extensive researching but unfortunately can't get it to working.
Source "#openzeppelin/contracts/token/ERC20/ERC20.sol" not found: File import callback not supported
I had same issue. I had multiple folders added in the unnamed workspace. After removing all other folders and keeping only one project folder resolved issue for me.
Linting issues
If you see something along the lines of:
ParserError: Source "OpenZeppelin/openzeppelin-contracts#3.4.0/contracts/access/Ownable.sol" not found: File not found.
import "#openzeppelin/contracts/access/Ownable.sol";
In your vscode, these and be safely ignored. However you can also add to your settings to ignore these.
Create a .vscode folder at the root of your project.
Create a file called settings.json
Add the following code:
{
"solidity.remappings": [
"#chainlink/=/Users/patrick/.brownie/packages/smartcontractkit/chainlink-brownie-contracts#0.2.2",
"#openzeppelin/=/Users/patrick/.brownie/packages/OpenZeppelin/openzeppelin-contracts#4.3.2"
]
}
Or whatever version your #chainlink and #openzeppelin contracts need. For example:
For more information see here
Use single quotes instead of doubles.
Instead of:
import "#openzeppelin/contracts/token/ERC20/ERC20.sol";
use this:
import '#openzeppelin/contracts/token/ERC20/ERC20.sol';
I am trying to import a module in my python script and I can't make it work.
So I have my python script: /home/user/pythonscript/oneDir/onescript.py
And I would like to use a script that is a directory higher in hierarchy:
/home/user/pythonscript/common.py
So I did the following at the top of my onescript.py:
import sys
sys.path.insert(1,'/home/user/pythonscript')
import common
In my common.py file, I have a function onecConnect, and when I try to run onescript.py, which uses onecConnect function, I get the following error: nameError: name 'onecConnect' is not defined
Anyone can see what I do wrong or forgot to do?
Thanks
Make sure there are __init__.py in all directories, go to /home/user/pythonscript and run Python code from there. So:
python oneDir/onescript.py
In onescript.py you can do:
from common import onecConnect
The rules are:
Always run a Python script from the highest possible directory (not the deepest into the project).
Always have full import lines, no relative imports.
This keeps the problems away.
I'm trying to import an existing project into Eclipse. I did the following steps:
- I downloaded the source from a repository.
- I ran ./autogen.sh
- I ran ./configure
- I selected Makefile Project with Existing Code from Eclipse File menu
The class files are now grouped by type (.h and .cpp) and I can reach .cpp from .h by pressing ctrl+Tab and vice versa.
When I press Build, the building starts and works fine. If I put syntax errors inside a file the make returns an error.
However Eclipse's intellisense reports many error like "Function snprintf could not be resolved", and "Symbol 'NULL' could not be resolved".
How can I hide/resolve these errors? Was my import procedure incomplete?
You should add /usr/include to the path (see http://help.eclipse.org/juno/topic/org.eclipse.cdt.doc.user/tasks/cdt_t_proj_paths.htm) or tune the Discovery options (http://help.eclipse.org/juno/topic/org.eclipse.cdt.doc.user/reference/cdt_u_newproj_discovery_options.htm?cp=11_4_6_8_2_2)
