vite throws file not found error when bootstrap5 added to sveltekit app.html

I added bootstrap5 via style and script tags in app.html
bs5 works fine but vite throws error that files are not found.
any advice?
Error message
Error: Not found: /vendors/bootstrap-5.0.2/bootstrap.min.css.map
Error: Not found: /vendors/bootstrap-5.0.2/bootstrap.bundle.min.js.map
files located:
/static/vendors/bootstrap-5.0.2/bootstrap.min.scss
/static/vendors/bootstrap-5.0.2/bootstrap.bundle.min.js
I would not recommend adding anything to the app.html, instead import from a root +layout.svelte, installing bootstrap from NPM.
The errors refer to .map files that specify what parts of a minified JS file refer to which lines in a source file. You probably did not copy the files over, so they cannot be found. The files are reference from the .min.js files.
But as noted, one should not import scripts like that.
When installing from NPM you need the packages:
bootstrap
#popperjs/core
It is possible to import just the code for specific components and compile the CSS from source (see docs). To import all code and styles you just need:
<script>
import 'bootstrap';
import 'bootstrap/dist/css/bootstrap.css';
</script>
It is preferred to only import what is actually needed to reduce the resulting bundle size.

Cannot find reference 'ximgproc' in '__init__.py

i want to use cv2.ximgproc module.
this is add-on module at Opencv
but there is a problem to load module.
I tried pip install opencv-contrib-python but it doesn't work.
to be precise its already installed but can't not find cv2.ximgproc module.
import cv2
...
cv2.ximgproc.thinning( ... )
that's my import section.
So, I tried paste source file from OpenCV github
but there is only C++ source..
( sometimes .py file exist. but that is not file I need. )
It is just PyCharm Error.
PyCharm represents 'Can't find'.
but I Run my code, and its works well..

ModuleNotFoundError: No module named 'autokeras.image_supervised'

Installed AutoKeras and pre-reqs in 3.6 Python environment using Anaconda.
Trying to test AutoKeras in Jupyter, but keep getting this error:
ModuleNotFoundError: No module named 'autokeras.image_supervised'
from autokeras.image.image_supervised import load_image_dataset
works for me (seems they changed files' structure of project)
I'm using autokeras-0.3.5
from autokeras import ImageClassifier
if this problem is arised then there might be a chance that u might have not installed autokeras library in the enironment.... I got the same error in Colab notebook try this code
!pip install autokeras
This might solve your problem.....

import errors after installing vtk

I used brew to install vtk. When I try to import vtk in Python, I get ImportError: No module named vtkIOImagePython
I'm assuming something is maybe wrong with my paths, but I can't figure it out.
Thanks!

Dart pub get command is not working properly when i try to pull my dependencies

I have my project in github. I already created it like a library (Dart). Now I am trying to use my library in one of my project.
After i add all the necessary comments to get it from my git source, pub get is giving the following error,
Warning: Package <library_name> does not have a "lib" directory so you will not be able to import any libraries from it.
Got dependencies!
Any clue???
Thanks,
Tham
When importing libraries, the files you import come from the lib folder.
Eg:
import 'package:danny/danny.dart';
will import the file lib/danny.dart from the danny package.
If the package doesn't have a lib folder; this means you can't possibly import it. If you're importing directly from a Git repo; you need to ensure the lib folder is a top-level folder.
