| Can't reference my Entity Model for Sql-to-Linq query Posted: 15 Apr 2021 08:58 AM PDT I've made an entity model in a folder called "Entity" that contains my only entitymodel. project.Entity.ListModel.edmx Within my main program.cs, I'm trying to call upon it to navigate some of the tables: var query = ListModel.TableName.Where(x => x.name..
But it keeps saying ListModel does not exist in current context. I've even tried the full path like: project.Entity.ListModel.TableName.Where..... But no luck. This seems like a simple fix, though I'm not well aquainted with Entity Frameworks or Linq for that matter. Any guidence would be welcome. Thanks  |
| python scale irregular multidimensional dataframe Posted: 15 Apr 2021 08:58 AM PDT I have a dataframe like the one in the example below: import pandas as pd data = {'a1': [40, 0, 40, 100, 80], 'a2': [[0, 2], [4, 5], [10, 2], [3, 8], [0, 0]], 'a3': [[10, 2], [10, 0, 4], [1, 0, 1, 1], [-10, 6], [0, 2]], 'a4': [-1, -0.08, 0.4, 1, 0.2], } df = pd.DataFrame(data) print(df) a1 a2 a3 a4 0 40 [0, 2] [10, 2] -1.00 1 0 [4, 5] [10, 0, 4] -0.08 2 40 [10, 2] [1, 0, 1, 1] 0.40 3 100 [3, 8] [-10, 6] 1.00 4 80 [0, 0] [0, 2] 0.20
and I would like to scale it to [0, 1] and also save the scalers, so that I can apply them on another dataset.
With dataframes without nested lists, I've been using MinMaxScaler this way: from sklearn.preprocessing import MinMaxScaler df1 = df[['a1', 'a4']] scaler = MinMaxScaler() scaler.fit(df1) scaled_df = scaler.transform(df1) dump(scaler, open('scaler.pkl', 'wb')) scaler = load(open('scaler.pkl', 'rb')) scaled_df2 = scaler.transform(df2)
but this is not working on the whole original df with nested lists. I can think about some "hacky" approaches such as for each column, concatenate its rows in one array, calculate the scalar, store it in an array of scalars and apply it to the second dataframe, but I was wondering if there is a better, cleaner approach to do this. Any ideas?  |
| How to stop horizontal stretching of a Image using Xamarin Posted: 15 Apr 2021 08:58 AM PDT I have a horizontal <ScrollView/>. When I put <Image/> in every <StackLayout/>. When you press the load button, each frame is stretched. If you press the button 5 times, the frame stretches 5 times. <ScrollView BackgroundColor="Transparent" Orientation="Horizontal" HorizontalOptions="FillAndExpand"> <StackLayout HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand"> <Grid BackgroundColor="Transparent"> <Grid.RowDefinitions> <RowDefinition Height="*" /> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="*" /> <ColumnDefinition Width="*" /> <ColumnDefinition Width="*" /> <ColumnDefinition Width="*" /> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions> <Frame Grid.Column="0" BorderColor="White" Margin="10,0,5,0" CornerRadius="10" BackgroundColor="Transparent"> <RelativeLayout> <Image x:Name="ImageDescriptionForecastTest" Aspect="AspectFill" RelativeLayout.HeightConstraint="{ConstraintExpression Type=RelativeToParent, Property=Height, Factor=1}" RelativeLayout.WidthConstraint="{ConstraintExpression Type=RelativeToParent, Property=Width, Factor=1}"/> <StackLayout> ..... ..... </StackLayout> </RelativeLayout> </Frame>
When I remove this line of the code: <Image x:Name="ImageDescriptionForecastTest" Aspect="AspectFill" RelativeLayout.HeightConstraint="{ConstraintExpression Type=RelativeToParent, Property=Height, Factor=1}" RelativeLayout.WidthConstraint="{ConstraintExpression Type=RelativeToParent, Property=Width, Factor=1}"/>
When I press the button, nothing stretches and everything works normally. In the very logic of the button I check weather condition and change the backgrounds: if (descriptionForecast1 == "clear sky") { ImageDescriptionForecastTest.Source = "Images/ClearSky.jpg"; } else if (descriptionForecast1 == "few clouds") { ImageDescriptionForecastTest.Source = "Images/FewClouds.jpg"; } else if (descriptionForecast1 == "scattered clouds") { ImageDescriptionForecastTest.Source = "Images/Scattering.jpg"; } else if (descriptionForecast1 == "broken clouds") { ImageDescriptionForecastTest.Source = "Images/BrokenClouds.jpg"; } else if (descriptionForecast1 == "light rain") { ImageDescriptionForecastTest.Source = "Images/LightRain.jpg"; } else if (descriptionForecast1 == "rain") { ImageDescriptionForecastTest.Source = "Images/Rain.jpg"; } else if (descriptionForecast1 == "thunderstorm") { ImageDescriptionForecastTest.Source = "Images/Thunderstorm.jpg"; } else if (descriptionForecast1 == "snow") { ImageDescriptionForecastTest.Source = "Images/Snow.jpg"; } else if (descriptionForecast1 == "mist") { ImageDescriptionForecastTest.Source = "Images/Mist.jpg"; } else if (descriptionForecast1 == "overcast clouds") { ImageDescriptionForecastTest.Source = "Images/OverCastClouds.jpg"; } else if (descriptionForecast1 == "moderate rain") { ImageDescriptionForecastTest.Source = "Images/ModerateRain.jpg"; }
What should I change in this code so that the frames are not stretched ? <Image x:Name="ImageDescriptionForecastTest" Aspect="AspectFill" RelativeLayout.HeightConstraint="{ConstraintExpression Type=RelativeToParent, Property=Height, Factor=1}" RelativeLayout.WidthConstraint="{ConstraintExpression Type=RelativeToParent, Property=Width, Factor=1}"/>
I will attach a screenshot from simulator:   |

When I run it locally, it works fine, as it creates a DB file on the first run, which then allows it to obtain your current xp and level, even if I stop the bot for a while. However, I host my bots by uploading the files to GitHub, and then using Heroku. When I run it like that, no file is created in my github repository, and when the bot gets turned off and on again, the levels reset, as it hasn't got any database. How can I make it so it backs up to a Database file when using GitHub and Heroku, like it does when I host it locally? Thanks!  |
| Cannot get torch.jit.script to work correctly with pytorch RNN Posted: 15 Apr 2021 08:57 AM PDT Ok, I need to script pytorch LSTM as when I do tracing it gets different answers with different inputs. But when I do: script_module=torch.jit.script(torch.nn.modules.rnn.LSTM(768, 256, num_layers=2, batch_first=True, bidirectional=True))
the resulting script_module prints as: RecursiveScriptModule(original_name=LSTM), but unlike other recursivescriptmodules (for example, as produced here: https://pytorch.org/tutorials/beginner/Intro_to_TorchScript_tutorial.html, and successfully replicated by me) it has no .code or .graph attribute, and it cannot be called. So what am I doing wrong? It obviously "thinks" it has produced a correct script.  |
| get parent or previous element based on child or sibling class Posted: 15 Apr 2021 08:57 AM PDT Imagine I have three different types of product HTML and I want to select the product-block element for only those that have a child or sibling with an input element that has a class mySelector. - Type A has the element with 'mySelector' within.
- Type B doesn't have an element 'mySelector' within or below it, so we don't want to select it.
- Type C has the element 'mySelector' right after it.
Product block type A <div class="A B C"> <a href="#"></a> <input type="hidden" class="mySelector"> </div>
Product block type B <div class="MM NN OO"> <a href="#"></a> </div>
Product block type C <div class="X Y Z"> <a href="#"></a> </div> <input type="hidden" class="mySelector">
The goal is to select product block types A and C, which have no child or sibling with mySelector. I imagine a filter could work, but I only can select one type of product-block with a filter like this: jQuery('.mySelector') .filter(function () { if (jQuery(this).prev().hasClass('wc-block-grid__products')) { return jQuery(this).prev(); } })
Another approach is using jQuery('.mySelector').parent(). But then I would not be able to select type C where mySelector is a sibling.  |

| Passing files from a rocker container to a latex container within a gitlab-ci job Posted: 15 Apr 2021 08:57 AM PDT I would like to use Gitlab CI to compile a Latex article as explained in this answer on tex.stackexchange (a similar pdf generation example is show in the gitlab documentation for artifacts). My Latex article contains figures made with the R statistical language. R and Latex are two large installation with a lot of dependencies so I decided to use two separate containers for the build, one for R stuff and one for the Latex stuff. Here is the content of my .gitlab-ci.yml: knit_rnw_to_tex: image: rocker/verse:4.0.0 script: - Rscript -e "knitr::knit('article.Rnw')" artifacts: paths: - figure/ compile_pdf: image: aergus/latex script: - ls figure - latexmk -pdf -bibtex -use-make article.tex artifacts: paths: - article.pdf
The knit_rnw_to_tex job executed in the R "rocker" container is successful and I can download the figure artifacts from the gitlab "jobs" page. The issue in the second job compile_pdf is that ls figure shows me an empty folder and the Latex article compilation fails because of missing figures. How can I pass the artifacts from one job to the other? Should I use cache as explained in docs.gitlab.com / caching?  |

| Chrome is Changing the Session Cookie when Calling cart/edit in Opencart 3.0.3.6 Posted: 15 Apr 2021 08:58 AM PDT I'm running Opencart 3.0.3.6 as an intranet supply ordering site on a 2019 server running iis 10 and php 7.3.13. I'm having one hiccup I cannot wrap my head around. The site works fine in every place except when users try to adjust item quantity in their carts. From what I can see, when opencart calls /cart/edit, sometimes chrome will change the session cookie value of OCSESSID, dropping that users session and logging them out. Sometimes the user can make 3-4 changes, sometimes the user needs to log back in a dozen times before they can make a successful change without being logged out. The site works fine with Firefox (staff use chromebooks, otherwise I'd just make them use firefox for the time being). EDIT: I've found samesite settings in Google Admin that allow me to use legacy cookie settings for specific sites. This practically solves my issue, but I would be interested to know the right way to set Opencart to use secure samesite settings that Chrome doesn't hate. I've found some solutions involving "samesite" settings, but nothing has quite worked out for me yet. I've tried applying someone's vqmod: <?xml version="1.0"?> -<modification> <id>Framework and catalog session samesite cookie</id> <vqmver>2.5.0</vqmver> <version>1.0</version> <author>J.J. van de Merwe</author> -<file error="log" name="system/framework.php"> -<operation> -<search position="replace"> -<![CDATA[ setcookie($config->get('session_name'), $session->getId(), ini_get('session.cookie_lifetime'), ini_get('session.cookie_path'), ini_get('session.cookie_domain')); ]]> </search> -<add action="after"> -<![CDATA[ // ### Modified code: your-filename.xml ### setcookie( $config->get('session_name'), $session->getId(), [ 'expires' => ini_get('session.cookie_lifetime'), 'path' => ini_get('session.cookie_path'), 'domain' => ini_get('session.cookie_domain'), 'secure' => true, 'httponly' => true, 'samesite' => 'None' ] ); // ### (End) Modified code ### ]]> </add> </operation> </file> -<file error="log" name="catalog/controller/startup/session.php"> -<operation> -<search position="replace"> -<![CDATA[ setcookie($this->config->get('session_name'), $this->session->getId(), ini_get('session.cookie_lifetime'), ini_get('session.cookie_path'), ini_get('session.cookie_domain')); ]]> </search> -<add action="after"> -<![CDATA[ // ### Modified code: your-filename.xml ### setcookie( $this->config->get('session_name'), $this->session->getId(), [ 'expires' => ini_get('session.cookie_lifetime'), 'path' => ini_get('session.cookie_path'), 'domain' => ini_get('session.cookie_domain'), 'secure' => true, 'httponly' => true, 'samesite' => 'None' ] ); // ### (End) Modified code ### ]]> </add> </operation> </file> </modification>
for some reason this resolves my issue on my local test server, but accessing the server from a remote machine causes Chrome to continuously drop the cookie altogether. I'm just totally lost on why the problem is so intermittent, and I'm not sure where to go from here.  |
| How to get element from HTML (Angular) Posted: 15 Apr 2021 08:58 AM PDT I have a little problem, I want to create a form using Angular : here is my HTML : <form [formGroup]="requeteForm" (ngSubmit)="ajouter()" *ngIf=" tables!= null"> <div class="form-group" *ngFor="let col of colonne; let i=index"> <label for="{{col}}">{{col}}</label> <input type="text" class="form-control" id="{{col}}" formControlName="{{col}}"> </div> </form>
As you can see the formControlName take a variable, the problem is how can I get the variable to init the formGroup ? For exemple : this.requeteForm = this.formBuilder.group( { {{col}}: ['', Validators.required], //It's just an exemple about what I want to do } );
Hope you can help me ^^ Thank you  |
| Microsoft Access Progress Bar Aggregation Posted: 15 Apr 2021 08:57 AM PDT I am after some advice relating to progress bars in ms access. I currently have a database which has a code to run a number of queries. There is a status bar which displays the progress of each query in the bottom right corner of the screen- Is there a way of feeding this info into a form? I want to display 2 progress bars in effect: 1st bar to display the status bar progress 2nd bar to display the overall progress of the code Can this be done? I did a bit of research and the closest thing that I can see is to customise the status bar itself: https://docs.microsoft.com/en-us/office/vba/access/concepts/miscellaneous/use-the-status-bar-progress-meter thanks  |

| Is there a way to limit the number of features in IML package Shapley values? Posted: 15 Apr 2021 08:57 AM PDT I have an automl model created with the H2O package. Currently, H2O only calculates Shapley values on tree-based models. I've used the IML package to calculate the values on the AML model. However, because I have a large number of features, the plot is too jumbled to read. I'm looking for a way to select/show only the top X number of features. I can't find anything in the IML CRAN PDF nor in other documentation I've found by Googling. #initiate h2o h2o.init() h2o.no_progress() #create automl model (data cleaning and train/test split not shown) set.seed(1911) num_models <- 10 aml <- h2o.automl(y = label, x = features, training_frame = train.hex, nfolds = 5, balance_classes = TRUE, leaderboard_frame = test.hex, sort_metric = 'AUCPR', max_models = num_models, verbosity = 'info', exclude_algos = "DeepLearning", #exclude for reproducibility seed = 27) # 1. create a data frame with just the features features_eval <- as.data.frame(test) %>% dplyr::select(-target) # 2. Create a vector with the actual responses response <- as.numeric(as.vector(test$target)) # 3. Create custom predict function that returns the predicted values as a # vector (probability of purchasing in our example) pred <- function(model, newdata) { results <- as.data.frame(h2o.predict(model, as.h2o(newdata))) return(results[[3L]]) } # example of prediction output pred(aml, features_eval) %>% head() #create predictor needed predictor.aml <- Predictor$new( model = aml, data = features_eval, y = response, predict.fun = pred, class = "classification" ) high <- predict(aml, test.hex) %>% .[,3] %>% as.vector() %>% which.max() high_prob_ob <- features_eval[high, ] shapley <- Shapley$new(predictor.aml, x.interest = high_prob_ob, sample.size = 200) plot(shapley, sort = TRUE)
Any suggestions/help appreciated. Thank you, Brian  |

Hey everyone, I'm building a Diet App, the food gets created in FoodCreate.js by typing a food and pressing the checkmark Icon, and this will create the food and display it in the FoodList.js, keep it in mind that the first Screen to be displayed is FoodList.js. When I run the code I get the following error: undefined is not an object (this.props.navigation.getParam)  |
| Flutter null safety conditional widget Posted: 15 Apr 2021 08:57 AM PDT Before Flutter introduced the null-safety feature, I was able to conditionally add Widgets within a list like so: actions: <Widget>[ canCancel ? CupertinoDialogAction( child: Text(cancelActionText), onPressed: () { Navigator.pop(context); }, ) : null, ].where(notNull).toList()
notNull being a homemade filter that filters off the null objects...
Now with null-safety it's impossible because the list of Widgets strictly has to be non-null. What would be a better approach?  |
| Get last position known in foreground Android Posted: 15 Apr 2021 08:57 AM PDT After several (unsuccessful) attempts to make my applications compliant about the background access to the location, I decided to re-structure my code in order to remove the ACCESS_BACKGROUND_LOCATION permission from the manifest. My application necessarily needs to get the location of the device at certain times (specifically I need the coordinates), what I'm interested in knowing is: without using the permission mentioned above, how do I get the location of the device? is it possible to do it with a one-time call without using services etc? I thought about using this code, do you think it could be enough? LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE); Location lastKnownLocation = locationManager.getLastKnownLocation(locationProvider); mFusedLocationClient = LocationServices.getFusedLocationProviderClient(this); mFusedLocationClient.getLastLocation() .addOnSuccessListener(this, new OnSuccessListener<Location>() { @Override public void onSuccess(Location location) { if (location != null) { // Logic to handle location object } } });
or something like this: LocationManager mLocationManager = (LocationManager) context.getSystemService(LOCATION_SERVICE); List<String> providers = mLocationManager.getProviders(true); Location bestLocation = null; for (String provider : providers) { Location location = mLocationManager.getLastKnownLocation(provider); if (location == null) { continue; } if (bestLocation == null || location.getAccuracy() < bestLocation.getAccuracy()) { bestLocation = location; } }
is there a better way to do this?  |
| Flutter firestore - Check if document ID already exists Posted: 15 Apr 2021 08:58 AM PDT I want to add data into the firestore database if the document ID doesn't already exists. What I've tried so far: // varuId == the ID that is set to the document when created var firestore = Firestore.instance; if (firestore.collection("posts").document().documentID == varuId) { return AlertDialog( content: Text("Object already exist"), actions: <Widget>[ FlatButton( child: Text("OK"), onPressed: () {} ) ], ); } else { Navigator.of(context).pop(); //Adds data to the function creating the document crudObj.addData({ 'Vara': this.vara, 'Utgångsdatum': this.bastFore, }, this.varuId).catchError((e) { print(e); }); }
The goal is to check all the documents ID in the database and see in any matches with the "varuId" variable. If it matches, the document won't be created. If it doesn't match, It should create a new document  |
| Bean definition is overriden by AutoConfiguration Posted: 15 Apr 2021 08:57 AM PDT In my Spring application I have defined a bean of type AuditListener. @Component public class AuditListener { }

| Order a MySQL table by two columns Posted: 15 Apr 2021 08:58 AM PDT How do I sort a MySQL table by two columns? What I want are articles sorted by highest ratings first, then most recent date. As an example, this would be a sample output (left # is the rating, then the article title, then the article date) +================+=============================+==============+ | article_rating | article | article_time | +================+=============================+==============+ | 50 | This article rocks | Feb 4, 2009 | +----------------+-----------------------------+--------------+ | 35 | This article is pretty good | Feb 1, 2009 | +----------------+-----------------------------+--------------+ | 5 | This Article isn't so hot | Jan 25, 2009 | +================+=============================+==============+ The relevant SQL I'm using is: ORDER BY article_rating, article_time DESC
I can sort by one or the other, but not both.  |
