QUESTION
I'm new to Python and I want to understand how I can remove values from my dataset that are 0.00000 In context, I am working on the dataset https://www.kaggle.com/ksuchris2000/oklahoma-earthquakes-and-saltwater-injection-wells
The file InjectionWells.csv has some values in their coordinates (LAT and LONG) which I need to remove but I don't know exactly how. This is so I can make a scatterplot with X longitude and Y latitude
I tried the following but didn't work. Can you please guide me?
...ANSWER
Answered 2021-May-21 at 00:47You can create a Boolean series by comparing a column of a dataframe to a single value. Then you can use that series to index the dataframe, so that only those rows that meet the condition are selected:
QUESTION
I am creating a short RPG game for my AP CSP project and for some reason when I call the method Element in line 310-313, it just ends the rest of the code in Main (which is all the remaining code in the program). The user is required to press x to continue the game but it skips all of that and auto-fills the user-inputs correctly. Put it short, once you select your element in the code, the program finishes the game by itself, which is not supposed to happen since the user needs to have its input to continue the dialogue.
Aforementioned, the intended output of this code is to complete the dialogue with the user input and user information only. Please help as this is due soon!

I have a leaflet map with some interactivity on it, and i just want to add a fixed logo on the top left corner of the map.
Here is my code: https://codepen.io/paul-k/pen/OJWYaxw

I don't know how to pin a logo which doesn't move on the top left corner of the map!
Thanks for helping :)

QUESTION
I am trying to fetch the data from Earthquake API.
I am using retrofit. The data is in XML
format. I am getting the data fine in XML. I am converting it in JSON using a XML-JSON Converter Library. And the library works just fine when i tried it with a simple xml string such as
Hello
.
And the library really converts it in JSON.
But while converting the data fetched from the api, it gives me this error:

QUESTION
I'm attempting to implment a Map
on a SwiftUI view from a view model. Every example I find online hard codes a coordinate. In my case, I'm initializing a view model with a Codable
struct and I have no idea what the coordinate is going to be.
I do not encounter compiler issues when I build the project, but canvas crashes. I've tried closing Xcode, cleaning derived data, etc., but that doesn't seem to resolve it.
Any suggestions re: where my mistake is are greatly appreciated.

QUESTION
Apple has shown us how to perform heavy write operation using background thread (by using newBackgroundContext
) in their official earth quake example - https://github.com/yccheok/earthquakes-WWDC20
But, what about heavy read operation? (millions of rows for stress test purpose)
We would also like our app UI to be responsiveness, when we are launching the app for first time, and the app is reading a large amount of data from CoreData.
The following is the code snippet which is using NSFetchedResultController
.
ANSWER
Answered 2021-Mar-29 at 14:14I think it is possible that your problem is the assignment of the fetchedResultsControllerDelegate
by the new controller. This seems to be inferable from where you encounter the multithreading violation.
From the code you provided, it is not clear what kind of object the delegate is, but presumably it manages the UI and thus is on the main thread. You can see who this can potentially lead to a threading problem.
Thanks for posting a link to this question from my answer here https://stackoverflow.com/a/14710475/427083. I still think that it should work for you if you assign the FRC as the datasource
of you table once it is finished, and then reloadData
.
On a side note: while I find this problem interesting and challenging from an engineering point of view, I doubt that it is good architecture to deal with millions of records directly on a mobile device.

...ANSWER
Answered 2021-Mar-27 at 11:55The exception is thrown because you are calling your API from the main thread. The problem in your code is your are calling your API twice. Once in doInBackground
and then again in updateUi
.
Remove the call to QueryUtils.fetchEarthquakeData(url)
from updateUi
, it should look like this.
