The error is in above line. You forgot to close the brackets there. Change this: print(clf.predict(x_test[1:10]) to print(clf.predict(x_test[1:10])) And even after that you will get error in the line: clf.f1_score(…) The above line is wrong, it should be: f1_score(y_test, clf.predict(x_test)) solved Scikit-learn Custom Scoring Function 1
I recommend considering Mediator Pattern or an interface which will be implemented by your receiving activity classes; solved send data from one activity to multiple activity
Have you tried to add an INSERT before INTO LOSSES_FORFEED: INSERT INTO LOSSES_FORFEED That should work – at least for an MS SQl Server Database. But also the amount of arguments don’t match: the table LOSSES_FORFEED has 5 columns but in the select statement you’re providing 6 arguments. 2 solved This is someone else’s code. … Read more
The problem is here: if(0 == maps&(1<<k)){ The equality operator == has higher precedence than the bitwise-AND operator &. So the above evaluates to this: if ((0 == maps) & (1 << k )) { You need to add parenthesis to get the desired behavior: if (0 == (maps & (1 << k))) { You’ll … Read more
If you’re trying to print the output in a browser, you’ll have to attach the other essential parts of the rails flow: routes and views. The rails getting started doc walks through this pretty well. http://guides.rubyonrails.org/getting_started.html 1 solved Rails Read and Print integers on web
You need a doubly-linked list. This list uses a node class, in this case you can call it train. Each node has a name, as well as next and previous node. The list class will store the nodes. The example below is a simple version where all the members are public. You can improve it … Read more
You mix 2 things: defining 4 sets and reading them from input (as I understood from your “using scanf“). (Reading them from input makes no problem as new read values overwrite old.) Defining 4 sets in advance may be simply done by arrays: float as[4], bs[4], cs[4]; // as[0], bs[0], cs[0] is the 1st set, … Read more
Use set to change the value of variables and %var% for using them: set variable=4 echo Variable is equal to %variable%. pause Output: Variable is equal to 4. Press a key to continue . . . If you mean you want to know if a variable is defined, just use if defined <variable>: if defined … Read more
There is no best way, it depends on situation. Ideally, there is no need to exit at all, it will just return. int a() { return 2; } If there is a real need to exit, use return, there are no penalties for doing so. void insertElementIntoStructure(Element e, Structure s) { if (s.contains(e)) { return; … Read more
Try this code, but before you do adjust the two constants at the top to match the facts on your worksheet. The worksheet with the data must be active when the code is executed. Sub TransposeData() Const FirstDataRow As Long = 2 ‘ presuming row 1 has headers Const YearColumn As String = “A” ‘ … Read more
The reason for the observed behavior is the fact, that the factor levels are handled as string. Because of that, the sort is done in an alphabetical order. This results in “100” being before “99” in an ascending order. The workaround was a bit tricky, I have used the stringr package for easier manipulation of … Read more

Just for the record, what I was looking for was User Notifications. Here is a complete example. User Notifications func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool { UNUserNotificationCenter.current().requestAuthorization(options:[.badge, .alert, .sound]) { (granted, error) in if granted{ print(“User gave permissions for local notifications”) }else{ print(“User did NOT give permissions for local notifications”) } … Read more
This cannot work as void does not contain any member next. You must use your node structure struct tmpList * to access any members. Functions dealing with list manipulation should use the prope node type in the signature to get some type safety. If you really want to use void * in the signature, you … Read more
First of all if you want that something would happen you need to write that in the function. You already wrote variables, but you did nothing with them, so nothing could happen.
