| How to build an ensemble by combining features extracted from gap layer of 3 pretrained deep learning models Posted: 05 Jul 2022 01:48 AM PDT I trained mobilenetv2, InceptionV3 and Xception pre-trained models with dataset. I saved them with .h5 format. Now i want to build an ensemble in this way. First to extract features from gap layer of all above 3 models, second concatenate these features and third give it to sigmoid layer for classification. I trained and saved models model1.save('models/model1.h5')# mobilenetv2 model2.save('models/model2.h5')# InceptionV3 model3.save('models/model3.h5')# Xception
Iam not able to get idea to code to build an ensemble as per above specifications in python. Pls help me |
| Do I have to use and 'extend' eslint-plugin-react in eslintrc.js config while using and extending 'eslint-config-airbnb' already Posted: 05 Jul 2022 01:48 AM PDT I updated my Eslint rules using airbnb in my React typescript project. My project doesn't use 'create-reac-app'. So I have to extend airbnb since I am also using and extending airbnb-typescript. eslint-plugin-react and eslint-plugin-react-hooks are peer dependencies of eslint-config-airbnb. So do I need to extend plugin:react/recommended'?
I have this in the extend property inside eslintrc.js: extends: [ 'airbnb', 'airbnb-typescript', 'airbnb/hooks', // "plugin:@typescript-eslint/recommended", // "plugin:@typescript-eslint/recommended-requiring-type-checking", // "plugin:eslint-comments/recommended", 'plugin:react/recommended', 'plugin:jest/recommended', 'plugin:prettier/recommended', ],
To get the best out of Eslint and React, do I have to extend 'plugin:react/recommended', or something else or can I remove it since I am using airbnb and airbnb-typescript? |
| Laravel Eloquent giving different result from MySQL / MariaDB query when using "WHERE CONCAT" Posted: 05 Jul 2022 01:48 AM PDT I have a laravel eloquent query that is giving me a different result from the same query that I try at MariaDB Eloquent: $invoice = PurchaseInvoice::select("purchase_invoices.*", "purchase_contracts.contract_no", "partners.name as partner_name") ->join("purchase_contracts","purchase_contracts.id","purchase_invoices.purchase_contract_id") ->join("partners","partners.id","purchase_contracts.partner_id") ->join("commodity_po","purchase_contracts.id","commodity_po.purchase_contract_id") ->where("purchase_invoices.invoice_no", 'LIKE', '%'.$request->q.'%') ->orWhere("purchase_invoices.po_additional_no", 'LIKE', '%'.$request->q.'%') ->orWhere("purchase_contracts.contract_no", 'LIKE', '%'.$request->q.'%') ->orWhereRaw("(CONCAT(`contract_no`, `po_additional_no`) LIKE '%?%')", [$request->q])->get()
and it will generate query like this : select `purchase_invoices`.*, `purchase_contracts`.`contract_no`, `partners`.`name` as `partner_name` from `purchase_invoices` inner join `purchase_contracts` on `purchase_contracts`.`id` = `purchase_invoices`.`purchase_contract_id` inner join `partners` on `partners`.`id` = `purchase_contracts`.`partner_id` inner join `commodity_po` on `purchase_contracts`.`id` = `commodity_po`.`purchase_contract_id` where (purchase_invoices.invoice_no LIKE '%SLP0622/6A-%' or purchase_invoices.po_additional_no LIKE '%SLP0622/6A-%' or purchase_contracts.contract_no LIKE '%SLP0622/6A-%' or (CONCAT(`contract_no`, `po_additional_no`) LIKE '%SLP0622/6A-%')) and `purchase_invoices`.`deleted_at` is null;
when I run the query on laravel, it give me empty result 
but when I run the generated query on MySQL it give me 1 result 
Does anyone know why this can happened? is this because there is a slash '/' on the query? |
| In ggplot, why does one have to separately set axis.text.x and axis.text.y to element_blank() instead of just axis.text? Posted: 05 Jul 2022 01:48 AM PDT This code produces this plot: ggplot(mtcars, aes(x = cyl, y = mpg))+ geom_line()+ theme(axis.text = element_blank())
Where it seems that axis.text argument doesn't work. In order to make it work, one needs to do this: ggplot(mtcars, aes(x = cyl, y = mpg))+ geom_line()+ theme(axis.text.x = element_blank(), axis.text.y = element_blank())

| How to distribute an iOS app to a client organisation's employees? Posted: 05 Jul 2022 01:47 AM PDT We are a contracting company and we develop software that we provide use to clients via subscription service. We've just built an app on iOS for the first time and are trying to figure out how to distribute it to our client's employees. Unfortunately our client has some roadblocks and will not be getting Apple Business Manager. The client would also like to use their MDM software Citrix to manage the app. No clue how to incorporate this. So from my understanding, the only other way to distribute it is to sign the app with their ad-hoc profile and then provide a download link? Is this correct or is there a better way to do it? I've looked at Enterprise distribution but it looks as if this method assumes the organisation distributing the app has full proprietary ownership of the application which is not the case here (we own it). Is there a way around this? I'm learning the ropes here so not really sure what the best approach is. Would appreciate any further insight given the context I've provided. Cheers! |

| String formatting vs String Interpolation Posted: 05 Jul 2022 01:48 AM PDT Please help me understand the difference between the two concepts of String Formatting and String Interpolation. From Stackoverflow tag info for string-interpolation: String interpolation is the replacement of defined character sequences in a string by given values. This representation may be considered more intuitive for formatting and defining content than the composition of multiple strings and values using concatenation operators. String interpolation is typically implemented as a language feature in many programming languages including PHP, Haxe, Perl, Ruby, Python, C# (as of 6.0) and others. From Stackoverflow tag info for string-formatting: Commonly refers to a number of methods to display an arbitrary number of varied data types into a string. To me, they appear to be similar, but I hope there's some difference. Also, kindly clarify whether these are some technology-specific concepts, or, technology-agnostic concepts. (I was reading about these concepts in the context of Python. But quick google and bing searches brought up related articles in other programming languages such as Java, C#, etc.) |

| Where and how should I initialize service which is used for sending requests like HttpClient? Posted: 05 Jul 2022 01:48 AM PDT I am using Google Vision API and its C# library. I want to understand where should I initialize ImageAnnotatorClient and how should I register GoogleVisionApiService. ImageAnnotatorClient is used for sending images to the Google Vision API, like this _imageAnnotatorClient.DetectSafeSearchAsync(image). First way - register service as Singleton and initialize ImageAnnotatorClient in the constructor public class GoogleVisionApiService : IGoogleVisionApiService { private readonly IGoogleCredentialFactory _googleCredentialFactory; private readonly ImageAnnotatorClient _imageAnnotatorClient; public GoogleVisionApiService(IGoogleCredentialFactory googleCredentialFactory) { _googleCredentialFactory = googleCredentialFactory; _imageAnnotatorClient = InitializeClient(); } private ImageAnnotatorClient InitializeClient() { var googleCredential = _googleCredentialFactory.GetGoogleCredentialAsync().Result; var credential = googleCredential.UnderlyingCredential as ServiceAccountCredential; var imageAnnotatorClientBuilder = new ImageAnnotatorClientBuilder { Credential = credential }; var imageAnnotatorClient = imageAnnotatorClientBuilder.Build(); return imageAnnotatorClient; } public async Task<SafeSearchAnnotation> GetSafeSearchAnnotationAsync(string imageBase64) { var image = Image.FromBytes(Convert.FromBase64String(requestImage)); var labels = await _imageAnnotatorClient.DetectSafeSearchAsync(image); return labels; } }
Second way is to register service as Transient and initialize client every time service is called public class GoogleVisionApiService : IGoogleVisionApiService { private readonly IGoogleCredentialFactory _googleCredentialFactory; public GoogleVisionApiService(IGoogleCredentialFactory googleCredentialFactory) { _googleCredentialFactory = googleCredentialFactory; } public async Task<SafeSearchAnnotation> GetSafeSearchAnnotationAsync(string imageBase64) { var googleCredential = await _googleCredentialFactory.GetGoogleCredentialAsync(); var credential = googleCredential.UnderlyingCredential as ServiceAccountCredential; var imageAnnotatorClientBuilder = new ImageAnnotatorClientBuilder { Credential = credential }; var imageAnnotatorClient = await imageAnnotatorClientBuilder.BuildAsync(); var image = Image.FromBytes(Convert.FromBase64String(requestImage)); var labels = await _imageAnnotatorClient.DetectSafeSearchAsync(image); return labels; } }

| PrimeFaces 11 fileupload Posted: 05 Jul 2022 01:48 AM PDT I am just trying to run simple fileupload with primefaces 11. My body is: <h:body> <h:form enctype="multipart/form-data"> <p:fileUpload value="#{fileUploadBean.uploadedFile}" mode="simple" skinSimple="true"/> <p:commandButton value="Submit" ajax="false" action="#{fileUploadBean.upload}" styleClass="p-mt-3 ui-button-outlined p-d-block"/> </h:form> </h:body>
My bean is @Component public class FileUploadBean { private UploadedFile uploadedFile; private UploadedFiles files; public void upload() { String fileName = uploadedFile.getFileName(); String contentType = uploadedFile.getContentType(); byte[] contents = uploadedFile.getContent(); // Or getInputStream() } public void uploadMultiple() { System.err.println("uploadMultiple"); if (files != null) { for (UploadedFile f : files.getFiles()) { FacesMessage message = new FacesMessage("Successful", f.getFileName() + " is uploaded."); FacesContext.getCurrentInstance().addMessage(null, message); } } } public void handleFileUpload(FileUploadEvent event) { UploadedFile uploadedFile = event.getFile(); System.err.println(uploadedFile.getFileName()); FacesMessage message = new FacesMessage("Successful", event.getFile().getFileName() + " is uploaded."); FacesContext.getCurrentInstance().addMessage(null, message); } public UploadedFile getUploadedFile() { return uploadedFile; } public void setUploadedFile(UploadedFile uploadedFile) { this.uploadedFile = uploadedFile; } public UploadedFiles getFiles() { return files; } public void setFiles(UploadedFiles files) { this.files = files; } }
I added this ones to web.xml <context-param> <param-name>primefaces.UPLOADER</param-name> <param-value>auto</param-value> </context-param> <filter> <filter-name>PrimeFaces FileUpload Filter</filter-name> <filter-class>org.primefaces.webapp.filter.FileUploadFilter</filter-class> </filter> <filter-mapping> <filter-name>PrimeFaces FileUpload Filter</filter-name> <servlet-name>Faces Servlet</servlet-name> </filter-mapping> <servlet> <servlet-name>Faces Servlet</servlet-name> <servlet-class>javax.faces.webapp.FacesServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <!-- Map these files with JSF --> <servlet-mapping> <servlet-name>Faces Servlet</servlet-name> <url-pattern>/faces/*</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>Faces Servlet</servlet-name> <url-pattern>*.jsf</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>Faces Servlet</servlet-name> <url-pattern>*.faces</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>Faces Servlet</servlet-name> <url-pattern>*.xhtml</url-pattern> </servlet-mapping>
The problem is "upload" function is not triggering. If I delete the enctype="multipart/form-data" part "upload" function is triggering but uploadedFile field is getting null. Also I tried all examples in primefaces demo page and nothing is working. Is anyone has any idea ? I couldn`t find any answer that uses primefaces 11. Thanks |

| IIS rewrite still active eventhough it is disabled Posted: 05 Jul 2022 01:47 AM PDT I have this iis site for which I have added some rewrite rules. The rewrite rule itself is simple If I access the site www.a.com rewrite/redirect to www.b.com and redirect subpages to corresponding subpages on www.b.com So have via IIS manager setup some rewrite rules. <rewrite> <rules> <clear /> <rule name="Redirect to https" stopProcessing="true"> <match l=".*" /> <conditions> <add input="{HTTPS}" pattern="off" ignoreCase="true" /> </conditions> <action type="Redirect" l="https://{HTTP_HOST}{REQUEST_I}" redirectType="Permanent" appendQueryString="false" /> </rule> <rule name="https://shop.a.com/5e/ -> https://www.b.com/products/5/" enabled="true" patternSyntax="ExactMatch" stopProcessing="true"> <match l="https://shop.a.com/5e/" /> <action type="Redirect" l="https://www.b.com/products/5/" logRewrittenl="false" /> </rule> <rule name="https://shop.a.com/5e/ -> https://www.b.com/products/5/" enabled="true" patternSyntax="ExactMatch" stopProcessing="true"> <match l="https://shop.a.com/5e/" /> <action type="Redirect" l="https://www.b.com/products/5/" logRewrittenl="false" /> </rule> <rule name="https://shop.a.com/10e/ -> https://www.b.com/products/10/" enabled="false" patternSyntax="ExactMatch" stopProcessing="true"> <match l="https://shop.a.com/10e/" /> <action type="Redirect" l="https://www.b.com/products/10/" logRewrittenl="true" /> </rule> <rule name="https://shop.a.com/16e/ -> https://www.b.com/products/16/" enabled="false" patternSyntax="ExactMatch" stopProcessing="true"> <match l="https://shop.a.com/16e/" /> <action type="Redirect" l="https://www.b.com/products/16/" logRewrittenl="true" /> </rule> <rule name="https://shop.a.com/3e/ -> https://www.b.com/products/3/" enabled="false" patternSyntax="ExactMatch" stopProcessing="true"> <match l="https://shop.a.com/3e/" /> <action type="Redirect" l="https://www.b.com/products/3/" logRewrittenl="true" /> </rule> </rules> </rewrite>
prior to this I had a rewrite that rewrote shop.a.com to www.b.com This one should not be active anymore, but for somereason is this still active, and all the other rules listed here does not seem to work. When I access shop.a.com/5e I enter www.b.com. The network tab in chrome states that the url is being redirected to www.b.com, but have no idea where this redirect is listed if not in the web.config? the url mentioned here are only examples and not the actual sites being managed. Any idea on why this redirect is doing this? |
| Export a folder of SQL queries into CSV in SSIS Posted: 05 Jul 2022 01:48 AM PDT I am a newbie to SSIS and currently struggling with executing SQL task saving the result in a result set and exporting each table to a respective CSV using a data flow task. There are 15 .sql files stored in a folder which I am creating a variable called FolderPath pointing towards them. Then I create a for each container that reads from a folder and create a variable in the variable mapping which is called SQLfile. Inside the for-each container I have an execute SQL task which I changed its file connection variable and edited the expression to FolderPath + SQLfile. Executing this loop works, when the result set value is set to none. Now I am trying to connect the tables created from this loop in a data flow task. I have no idea how to do this but I am guessing it has something to do with the result set. When I change the result set to full result set my loop breaks. I am assuming you cant have a result set inside a loop. Now I am completely lost as I don't know how to save the result of those 15 tables and how to declare them as source in the data flow task. |
| How to plot geodesic curves on a surface embedded in 3D? Posted: 05 Jul 2022 01:47 AM PDT I have in mind this video, or this simulation, and I would like to reproduce the geodesic lines on some sort of surface in 3D, given by a function f(x,y), from some starting point. The midpoint method seems computationally and code intense, and so I'd like to ask if there is a way to generate an approximate geodesic curve based on the normal vector to the surface at different points. Each point has a tangent vector space associated with it, and therefore, it seems like knowing the normal vector does not determine a specific direction to move forward the curve. I have tried working with Geogebra, but I realize that it may be necessary to shift to other software platforms, such as Python (or Poser?), Matlab, or others. Is this idea possible, and can I get some ideas as to how to implement it?
In case it provides some ideas as to how to answer the question, there previously was an answer (now unfortunatley erased) suggesting the midpoint method for a terrain with the functional form z = F(x,y), starting with the straight line between the endpoints, splitting in short segments [I presume the straight line on the XY plane (?)], and lifting [I presume the nodes between segments on the XY plane (?)] on the surface. Next it suggested finding "a midpoint" [I guess a midpoint of the segments joining each consecutive pairs of projected points on the surface (?)], and projecting "it" [I guess each one of these midpoints close, but not quite on the surface(?)] orthogonally on the surface (in the direction of the normal), using the equation Z + t = F(X + t Fx, Y + t Fy) [I guess this is a dot product meant to be zero... 
(?)], where (X,Y,Z) are the coordinates of the midpoint, Fx, Fy the partial derivatives of F, and t the unknown [that is my main issue understanding this... What am I supposed to do with this t once I find it? Add it to each coordinate of (X,Y,Z) as in (X+t, Y+t, Z+t)? And then?]. This is a non-linear equation in t, solved via Newton's iterations.
As an update / bookmark, Alvise Vianello has kindly posted a Python computer simulation of geodesic lines inspired on this page on GitHub. Thank you very much! |

| Find and replace entire MySQL database Posted: 05 Jul 2022 01:48 AM PDT I would like to do a find and replace inside an entire database not just a table. How can I alter the script below to work? update [table_name] set [field_name] = replace([field_name],'[string_to_find]','[string_to_replace]');
Do I just use an asterix? update * set [field_name] = replace([field_name],'[string_to_find]','[string_to_replace]');
