Say I have the following: test_labels=np.array([0,1,1,3,2]) and preds=np.array([0,2,3,3,2]) -- the output should then be output_fractions_correct=np.array([1.0, 0.0, 0.5, 0.5]), i.e., a summery of the accuracy of each class. How can I compute the number(fraction) of correctly classified example for a class and do this for each class? I would like to give you an example of what I have tried but trust me that wouldn't help. Thanks.

I think I can get it to work with for loops but there must be some wizard way with Numpy.

To elaborate: The accuracy of a class(the value of the array elements) is given by the number of indicies for which test_labels[i]=preds[i] divided by the number of occurences of class i in preds. This is for example why class 3 has an accuracy of 2/1=0.5. I am aware that in reality one would consider occurences in test_labels but that doesn't matter here :)

I'm trying to import into my database a csv file using Table Data Import Wizard tool, to a table that just has one attribute (it's id VARCHAR(10)), the import is failing showing me this error: error I've checked the csv file in order to find any wierd characters or newline characters but everything is fine. Im using version 8.0.25 and the logs are showing this:

I am trying to migrate or Copy one database from one server to another server. Here is what I have tried so far:

1. I used the SQL Server wizard to Migrate (Under the tasks) and it works fine except that I did not see an option to move the PKs and FKs with that . (Please let me know If I could do it)
2. I tried to generate the Script with PKs and FKs but the file size is around 10GB. Because the file is too large I use "sqlcmd -S -i C:\.sql " in CMD but it does not show the process.

So my question is, What is the best way to migrate or copy the database to another server with the Keys?

I am trying to show a model dialog in my application. For that as a first step I imported Material Dialog into my component.ts file

I'm trying to make a pop-up menu that has a couple different filters (buttons, selects, and text fields). I'm using the Material UI Menu component, but have run into an issue when trying to use the text fields. Because the Menu component is acting like a , when I type something in the text fields, it tries to select different MenuItems instead of staying focused on the text box.

So using the example found in the sandbox below, users wouldn't be able to type anything in the "search for a different food" textbox if it started with an "A", "B", or "C". If you wanted to type in "apricots", the menu would change focus from the textbox to the "Apples" MenuItem.

I don't see any props for this in the Menu API, so I'm curious to know if there is any work arounds, or even a different component that is more suited for this.

Thanks!

What is the best approach to add a web api as a project to the default ASP.NET Blazor solution? When using visual studio 2019 you no longer get the server and web projects when you select Blazor server on create new solution/project.

I found a way be browsing serveral blogs but it was mentioned that microsoft might dis-continue this.

Looking for the best way.
The reason I need to add an API to an ASP.NET Blazor Side project is to so the SyncFusion DataGrid can bind to it. See: https://blazor.syncfusion.com/documentation/datagrid/data-binding/#entity-framework

Here is what I am thinking of trying:

Use "options.EnableEndpointRouting" approach.

• Step 1: Create an API folder
• Step 2: Right Click/Add New/ Controller/Web API Step
• Modify Startup.cs with:

using Microsoft.AspNetCore.Mvc;

services.AddMvc(options => options.EnableEndpointRouting = false).SetCompatibilityVersion(CompatibilityVersion.Version_3_0);

app.UseMvcWithDefaultRoute();

Is this considered a future safe or supported way to do it?

Server Side Blazor Created By VS 2019 Wizard:

Solution generated looks like:

I have an array of objects as part of a data response that I am grouping together using lodash's groupBy via each object's groupName key.

Some of the items that come back have a groupName value of null, undefined or an empty string and lodash creates separate groups for each of those values.

I combine all of the falsey groups into a single group name "Uncategorized" and attempt to remove the original falsey groups to only return "Uncategorized" and all other truthy groups.

The problem I'm running into is that I'm trying to use the rest operator to remove the original falsy objects with undefined, null, and empty string keys by assigning them to a variable like let groupKeysToRemove = ['undefined', 'null', ''] and then trying to remove them like let { [groupKeysToRemove]: removed, ...groups } = initialGroups; but it returns the same Object with nothing removed. I'm not sure if my syntax is wrong or what but I am stumped.
