Question

我正在public class OddsOrEvens { public static Scanner sc = new Scanner(System.in); public static void main(String[] args){ System.out.println("Let’s play a game called \"Odds and Evens\""); System.out.println("Whats your name ? "); String name = sc.nextLine(); System.out.println("Hi "+ name +", which do you choose? (O)dds or (E)vens?"); String selection = sc.nextLine(); System.out.println("selection: " + selection); while (selection.compareToIgnoreCase("O") >0 || selection.compareToIgnoreCase("E") >0){ System.out.println("Please enter the correct choice. Select 'O' for odds or 'E' for evens"); selection = sc.next(); } if(selection.equalsIgnoreCase("O")){ System.out.println(name + " has picked Odds! The computer will be evens."); }else if (selection.equalsIgnoreCase("E")){ System.out.println(name + " has picked Evens! The computer will be Odds."); } }上试用Tensorflow示例，但是当我尝试使用Variables进行打印时出现错误

tf.Session

我很确定我没有在其他任何地方定义并在Spyder上删除了所有变量

ValueError: Variable my_int_variable already exists, disallowed. Did 
you mean to set reuse=True or reuse=tf.AUTO_REUSE in VarScope? Originally defined at:

在使用变量之前，不要初始化变量。试试这个：

class Goal(models.Model):
    # values that I am storing in my SQLlite DB
    title = models.CharField(max_length=1000)
    body = models.TextField()
    created_data = models.DateTimeField(auto_now_add=True, auto_now=False)
    updated_data = models.DateTimeField(auto_now_add=False, auto_now=True)
    user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
    # user = models.OneToOneField(User, on_delete=models.CASCADE)

    def __str__(self):
        return self.title

    # Where I am trying to authenticate the user
    def get_queryset(self, *args, **kwargs):
        return Goal.objects.all().filter(owner=self.request.user)

它在我的机器上产生零初始化数组。此外，最好在打印函数中评估变量。
