error-handling

问题 What are the big differences between raise Assertionerror and assert to build in a "fault". What are the effects on the code ? and is one or the other more pythonic in a way ? The reason for my question is because I am learning to program right now we have exercise where for example when x != "ok" (x be a certain number) we need to get an AssertionError "false". I looked this up online and then they say to set the following code: if x != 0: raise AssertionError ("false") but my teachers also

问题 I created a DataGenerator with Sequence class. import tensorflow.keras as keras from skimage.io import imread from skimage.transform import resize import numpy as np import math from tensorflow.keras.utils import Sequence Here, `x_set` is list of path to the images and `y_set` are the associated classes. class DataGenerator(Sequence): def __init__(self, x_set, y_set, batch_size): self.x, self.y = x_set, y_set self.batch_size = batch_size def __len__(self): return math.ceil(len(self.x) / self

问题 I have two simple wrappers that handle requests in my single page application. One wraps fetch and throws an error if a response is not ok (not in the 200-300 range): const fetchy = (...args) => fetch(...args).then(response => { if (response.ok) { return response } throw new Error(response.statusText) }) export default fetchy And one wraps fetchy and is used for GET requests: const get = endpoint => { const headers = new Headers({ Authorization: `Bearer ${TOKEN}` }) const init = { method:

问题 I have an Azure data factory v2 pipeline containing an until activity. Inside the until is a copy activity - if this fails, the error is logged, exactly as in this post, and I want the loop to continue. Azure Data Factory Pipeline 'On Failure' Although the inner copy activity’s error is handled, the until activity is deemed to have failed because an inner activity has failed. Is there any way to configure the until activity to continue when an inner activity fails? 回答1: Solution Put the error

问题 When a Uncaught Exception is thrown in some website or web application, an error appears in the Develper tools in each browser In Electron for instance, if an uncaught exception, the developer can set a listener and do whatever I want with the error message: process.on('uncaughtException', function (error) { // Handle the error } So, I wonder if there is an easy way to do the same in JavaScript. This could be useful in order to record and store common errors when the users are working, or in

问题 I can't understand why I cannot do more than one request without refreshing page. Any request is working fine, but If I need to execute another request (don't mind if it's the same or not)... I can't! I need to refresh the page to do a new request, otherwise, I'll get error 403. All the code is working, just, any request is finishing with refreshing the page. I don't like that because I consider it's not professional. What do I need to change in codeigniter to allow more than one request

问题 I'm working with a third-party library that provides tree-based data structures that I have to use "as is". The API returns Result<T, Error> . I have to make some sequential calls and convert the error to my application's internal error. use std::error::Error; use std::fmt; pub struct Tree { branches: Vec<Tree>, } impl Tree { pub fn new(branches: Vec<Tree>) -> Self { Tree { branches } } pub fn get_branch(&self, id: usize) -> Result<&Tree, TreeError> { self.branches.get(id).ok_or(TreeError {

问题 I'm enthusiastic about Deno so I'm giving it a try. Found a tutorial on building a REST API here. So, when I'm trying to run it, I get this InvalidData error: error: Uncaught InvalidData: data did not match any variant of untagged enum ArgsEnum at unwrapResponse ($deno$/ops/dispatch_json.ts:43:11) at Object.sendAsync ($deno$/ops/dispatch_json.ts:98:10) at async Object.connect ($deno$/net.ts:216:11) at async Connection.startup (https://deno.land/x/postgres/connection.ts:138:17) at async Client

问题 GameObject enemy = Instantiate(spawnObject,spawnPosition,spawnObject.transform.rotation) as GameObject; enemy.transform.parent = transform; The above code generates the expected result when I test my game in game mode, however I'm gettting this error message: "Setting the parent of a transform which resides in a prefab is disabled to prevent data corruption." Yes, the spawnObject variable contains a prefab, however creating a new GameObject should have fixed the problem, I assume? 回答1: Check
