label

问题 So I have a Label where when a button is pressed, it changes the name of the text to display another label below the existing label. It pretty much just prints the same label with a different text on the row below. When the Delete Text button is pressed, it will delete the new label that has been created but how do I delete the label before the new label? I can also only remove the label via destroy and not forget. I tried changing the text of the variable back to what it says on the window

问题 I am trying to run a regression problem on python using XGBOOST: import xgboost global clf clf = XGBRegressor(n_estimators = 500, learning_rate = 0.05, max_depth=6, n_jobs=4, alpha = 0.1) clf.fit(X_train, y_train, early_stopping_rounds = 5, eval_set = validation, verbose=False) predicted_test_tr = np.round(clf.predict(X_test)) But it raises the following error, after a few iterations: XGBoostError: b'[10:56:23] src/objective/regression_obj.cc:43: Check failed: info.labels_.size() != 0U (0 vs.

问题 Hi I am trying to add some text to a progress bar in bootstrap. The way I want it to look is the follow: Java: x-x-x-x-x-x-x-x-x- C++ : x-x-x-x-x-x-x-x-x- where x-x-x-x-x-x-x-x-x- is the progress bar. I have written some code but I can't seem to get the text inline with the progress bar. Any help would be useful. I am using just bootstrap. <div class="panel panel-default" style="height:500px;overflow:scroll"> <div class ="panel panel-primary"> <div class="panel-heading"> <h4>Programming

问题 I've got a set of labels in a flowbox, the problem is that I would like for these labels to be 96px wide at most. I've set label.set_ellipsize(True), but since the flowbox gives them as much room as they like they don't get ellipsized, even though I've set their size request to 96px wide. I've tried every function I could find that seemed even tangentially related on all the widgets involved, but nothing seems to work. the only workaround I did find was using set_min_children_per_line() but

问题 What I'd like it's to remove those labels on the right side, the ones on gray boxes on the side. I'll give an example: p <- ggplot(mtcars, aes(mpg, wt, col=factor(cyl))) + geom_point() p + facet_grid(cyl ~ .) Thanks in advance! Juan 回答1: The following would do that: p <- ggplot(mtcars, aes(mpg, wt, col=factor(cyl))) + geom_point() p <- p + facet_grid(cyl ~ .) p <- p +theme(strip.text.y = element_blank()) Without rectangles p <- ggplot(mtcars, aes(mpg, wt, col=factor(cyl))) + geom_point() p <-

问题 I'm trying to analyse a java code and see what it does, but in the "break label" line it gives the "Undefined label" error. from my understanding java unlike c# allows breaking into a scope outside of the current scope. isn't that right? if (conditions) { // some code if (conditions) { break label; } // some code } for (;;) { if (conditions) { // some code } // some code break; label: // some code } 回答1: In your example, you are trying to use break label; as though it were similar to the goto

问题 I want to place a label inside a frame in tkinter, but I can't figure out how to actually get it inside. import tkinter from tkinter import * W=tkinter.Tk() W.geometry("800x850+0+0") W.configure(background="lightblue") FRAME=Frame(W, width=100, height =50).place(x=700,y=0) LABEL=Label(FRAME, text="test").pack() When I run this, it doesn't place the Label inside the frame, but just places it normally on the window. What am I doing wrong? 回答1: In the line FRAME=Frame(W, width=100, height =50)
