You need to declare the pins like this:

pinMode(seg1, OUTPUT);
pinMode(seg2, OUTPUT);
pinMode(seg4, OUTPUT);
pinMode(seg5, OUTPUT);
pinMode(seg6, OUTPUT);
pinMode(seg7, OUTPUT);
pinMode(seg9, OUTPUT);
pinMode(seg10, OUTPUT);

  digitalWrite(seg1, HIGH);
  digitalWrite(seg2, HIGH);
  digitalWrite(seg4, HIGH);
  digitalWrite(seg5, HIGH);
  digitalWrite(seg6, HIGH);
  digitalWrite(seg7, HIGH);
  digitalWrite(seg9, HIGH);
  digitalWrite(seg10, HIGH);

There is absolutely no need to enable any pullup, the pins just need to be declared like outputs.
