Why won't the program include the first input from the user in the calculation of the average?

• Batch classification of images in Tensorflow java

  What's the best way to classify batch of images using TensorFlow java API? I also want the capability to resize the image in GPU so that all the images in the batch are of same dimension.

  The only example I have found in the internet is for a single image , here https://github.com/tensorflow/tensorflow/blob/master/tensorflow/java/src/main/java/org/tensorflow/examples/LabelImage.java .

  In python , I see there is a tf.stack method which allows to create a pack of tensors to create a batch request , I couldnt find anything equivalent to this method in java api.

  I found an example of batch request which uses opencv and tensorflow https://medium.com/@alexkn15/tensorflow-and-javacv-591c1b9443a3. Is there a better way to do this using standard tensor operations in java?
• How do I change PircBot nickname before I connect to the IRC?

  I'm a beginner Java programmer and recently I tried to do an IRC connection using PircBot. By reading documentation I have found out how to connect to the IRC using host, port and password. My problem is the server I want be connected with requires nickname as well (it's like a part of authentication).

  I tried to call out the changeNick() method before connecting to the server, but it always retured the same nickname, which is "PircBot". After digging into this method, I realised it's a final method that I cannot override. I also tried adding my nickname to the hostname (nickname@hostname), but it also didn't work.

  import org.jibble.pircbot.IrcException;
  import org.jibble.pircbot.PircBot;
  
  import java.io.IOException;
  
  public class Main {
  
      public static void main(String[] args) {
          PircBot irc = new PircBot() {};
          try {
              System.out.println(irc.getName()); // Returns 'PircBot'
              irc.changeNick("myNickIWantToUse");
              System.out.println(irc.getName()); // Also returns 'PircBot'
              irc.connect("hostname", port, "password"); //Also tried irc.connect("myNickIWantToUse@hostname", port, "password");
          } catch (IOException e) {
              e.printStackTrace();
          } catch (IrcException e) {
              e.printStackTrace();
          }
      }

• Why is this constant not printing to console? its just blank

  Here is a snipet of code from a bigger app. This function (is called when a button is clicked)just evaluates which selection from a picker was chosen and assigns a string to it and also get the input a user typed in a text field

  that part works fine and it even assigns the correct string that was selected in the picker

  i test this by printing the selected string in the console - so it all works great BUT I then try to print that string after the if/else structure and it only prints a blank

  Cant figure out the subjectField prints fine as its going through the if/else - so that logic works... but I try to print after thelogic and it prints just a blank line or carriage return (I had added another print statement after the print (subjectField) and it printed fine with a blank above it.

  thought it may be a variable issue tried making globals and then decided to try this asa function which is working but why in the heck id subjectField correct when it iterates through else if but not after.

  I am sure i am missing something simple....

  @IBAction func sendButtonPressed(_ sender: UIButton) {  
      determineSelRequest(selectedReq: pickedRequest.selectedRow(inComponent: 0), selectedFlightNumber: enteredFlightNumber.text!) 
  }
  
  func determineSelRequest(selectedReq: Int, selectedFlightNumber: String) {
  
      var selectedRequest = pickedRequest.selectedRow(inComponent: 0)
      if selectedRequest == 0 {
          var subjectField = "Fltsum "
          print (subjectField)
      } else if selectedRequest == 1{
          var subjectField = "Crew "
          //print (selectedRequest)
      } else if selectedRequest == 2{
          var subjectField = "EDCT "
          //print (subjectField)
      } else if selectedRequest == 3 {
          var subjectField = "Loads "
          //print (subjectField)
      } else if selectedRequest == 4 {
          var subjectField = "Times "
          //print (subjectField)
      }
  var selectedFlightNumber : String = enteredFlightNumber.text!
  
      // print ("now we just have to send mail")
      print (selectedFlightNumber)
      print (subjectField)
      //sendEmail()
  }
  

  want the string that the else/if logic put into subjectField to stay there.... not become blank
• if statement in for loop?

  I want to know if I can add a conditional statement as part of a for in loop. For example if I have the following situation:

  nameList = [person.name for  person in Persons.query.filter_by(category='Admin').all()]
  

  I want to add another statement such that only add to nameList if person.id is not in another list called blackListedIDs
• Using Filter Formula with Multiple Criteria and Allowing Blank Criteria

  Below is a link to a file with fake data. The 2nd tab is designed to allow users to filter the larger data set by selecting criteria from the drop-down. How do I design a formula (currently located in cell B12) so that it filters the larger data set from Sheet1, but if the user leaves "Activity" blank, it returns all results? Currently, the formula is requiring a selection in every dropdown. I want it so that if someone does NOT select something in a dropdown, that it will return all results based on what criteria have been entered.

• How to download new content with wget and conditional loop?

  I'm trying to download a list of videos via WGET that once the list is downloaded, it keeps checking to see if anything has been added to it. I'm doing this because the connection to the device could be weak/slow and I want to make sure it's up to date.

      Local=$(wc -c </local/$(hostname)_list.txt)
      Remote=$(curl -sI http://server.com/$(hostname)_list.txt | awk '/Content-Length/ {sub("\r",""); print $2}')
              #we compare if the size of the file on exec is different than on the server...aka it changed.
              while [ $Local != $Remote ]
              do
                      #download all the new videos from the list
                      sudo wget -c -i http://www.server.com/promote/vids_approved/$(hostname)/$(hostname)_list.txt -P /local/VIDS;
                      sudo wget -m -nd -nH -r -l1 --no-parent -A "txt"  http://www.server.com/promote/vids_approved/$(hostname) -P /local/VIDS 
  
       Local=$(wc -c < /var/www/html/videoloop/vids/$(hostname)_list.txt)
       Remote=$(curl -sI http://www.betheexec.com/promote/vids_approved/$(hostname)/$(hostname)_list.txt | awk '/Content-Length/ {sub("\r",""); print $2}')
  
  
              done
  

  The first time it runs, it does it correctly, however if the /$(hostname)_list.txt on the server gets updated while it's downloading the other videos, it assumes there's no changes and ends.
• Creating a Do While Statement in C#

  I have a C# program that asks the user to select a number 1-10 from the drop-down list. I want the user to select something higher than 0. If they select the 0 though when they click the final button, they will get the error message.

  Currently, when I select anything, the error message comes up. Not sure what my issue is.

  

  //if the user selects 0 for feet then write an error message
      do{
           //Print the error message
           lblFeet.Text = "Please Select a Number Other Than 0.";
           //Change the color of the error message to Red
           lblFeet.BackColor = System.Drawing.Color.Red;
       } while (ddlFeet.SelectedItem.Text == "0");
  
• For loop in a greedy algorithm isn't breaking, is asking for input infinitely

  I'm creating a greedy loop that finds the smallest amount of coins to be used to give back a value for CS50's pset1, and I can't decipher why my while loop is running infinitely.

  I've tinkered with it and can't get it to escape.

      do
      {
          input = get_float("Amount paid\n");
      }
      while(change_owed <=0);
      input = round(input);
  
      // begin checking 
      while(input > 0)
      {
          if(input - .25 > 0) // quarters
          {
              num_coins++; // number of coins used, to be printed later, is incremented
              input = input - .25; // coin is subtracted from total
          }
          else if (input - .10 > 0) // dimes
          {
              num_coins++;
              input = input - .10;
          }   
          else if (input - .05 > 0) // nickels
