Could you help me, I've got this error when I try building a project?

I recently upgraded all of my dependencies in package.json to the latest. I went from Angular 12.2.0 to 13.0.1 and github is now rejecting my push with the following file size error. Is there some setting I need to define in angular.json build profile that will help minimize these cache file sizes?
...ANSWER
Answered 2021-Nov-24 at 16:53Make sure your .gitignore
is in the parent folder of .angular
.
In that .gitignore
file, a simple .angular/cache/
should be enough to ignore that subfolder content.

QUESTION
I use the following method a lot to append a single row to a dataframe. One thing I really like about it is that it allows you to append a simple dict object. For example:
...ANSWER
Answered 2022-Jan-24 at 16:57Create a list with your dictionaries, if they are needed, and then create a new dataframe with df = pd.DataFrame.from_records(your_list)
. List's "append" method are very efficient and won't be ever deprecated. Dataframes on the other hand, frequently have to be recreated and all data copied over on appends, due to their design - that is why they deprecated the method
QUESTION
I am currently setting up a boilerplate with React, Typescript, styled components, webpack etc. and I am getting an error when trying to run eslint:
Error: Must use import to load ES Module
Here is a more verbose version of the error:
...ANSWER
Answered 2022-Mar-15 at 16:08I think the problem is that you are trying to use the deprecated babel-eslint parser, last updated a year ago, which looks like it doesn't support ES6 modules. Updating to the latest parser seems to work, at least for simple linting.
So, do this:
- In package.json, update the line
"babel-eslint": "^10.0.2",
to"@babel/eslint-parser": "^7.5.4",
. This works with the code above but it may be better to use the latest version, which at the time of writing is 7.16.3. - Run
npm i
from a terminal/command prompt in the folder - In .eslintrc, update the parser line
"parser": "babel-eslint",
to"parser": "@babel/eslint-parser",
- In .eslintrc, add
"requireConfigFile": false,
to the parserOptions section (underneath"ecmaVersion": 8,
) (I needed this or babel was looking for config files I don't have) - Run the command to lint a file
Then, for me with just your two configuration files, the error goes away and I get appropriate linting errors.
QUESTION
I am working on a spatial search case for spheres in which I want to find connected spheres. For this aim, I searched around each sphere for spheres that centers are in a (maximum sphere diameter) distance from the searching sphere’s center. At first, I tried to use scipy related methods to do so, but scipy method takes longer times comparing to equivalent numpy method. For scipy, I have determined the number of K-nearest spheres firstly and then find them by cKDTree.query
, which lead to more time consumption. However, it is slower than numpy method even by omitting the first step with a constant value (it is not good to omit the first step in this case). It is contrary to my expectations about scipy spatial searching speed. So, I tried to use some list-loops instead some numpy lines for speeding up using numba prange
. Numba run the code a little faster, but I believe that this code can be optimized for better performances, perhaps by vectorization, using other alternative numpy modules or using numba in another way. I have used iteration on all spheres due to prevent probable memory leaks and …, where number of spheres are high.

This code doesn't solve your problem completely. It simply finds the nearest 50 neighbors to each point in your 500000 point dataset:

Answered 2021-Aug-29 at 08:12The way your container is built doesn't add a user, so everything is done as root.

QUESTION
I have updated Cordova Android to the latest (10.1.1) and now when I build I get:
No usable Android build tools found. Highest 30.x installed version is 30.0.2; minimum version required is 30.0.3
I have the following reported when I start the build:
...ANSWER
Answered 2021-Nov-18 at 06:30Today, I could finally install version 30.0.3.
In Android Studio, I could see and install it from here...
After this, and then also having to remove the whitelist plugin (it is not required any more), I could get it to build.
Only hassle now is it outs to a .aab
and not an .apk
so side load testing now harder. But the main issue, the building is now working (on Windows PC).. Now hopefully can do the same on the Mac.

When testing components with s, for example in my answer to Recommended approach for route-based tests within routes of react-router, I often use the following pattern to get access to the current
location
for testing purposes:
ANSWER
Answered 2021-Nov-06 at 10:28React Router v6 splits apart the history into multiple pieces, for this use case the relevant parts are the navigator and the location. This change is hinted at in Use useNavigate
instead of useHistory
, and you can see it in the definition of the Navigator
type used in the Router
