问题 I need to clear console screen in Scala I've tried standard ANSI Clear screen which was suggested as "Terminal control/Clear the screen" by rosettacode.org here object Cls extends App {print("\033[2J")} I got following error: Error:(8, 14) octal escape literals are unsupported: use \u001b instead println("\033[2J") 回答1: I found solution for my question and I'll share it here for others, apparently from Scala 2.10 Octal litherals are deprecated see here. In question above "\033[2J" didn't work

问题 I have this program: object B{ def apply[T](c:T)={} } object C{ type T def apply(c:T)={} } object A extends App{ val d=B{println(1);2} val e=C{println(1);2} } the line val e = C{println(1);2} told me error:Type mismatch,expected C.T,actual:2 so why can't I write type T def apply(c:T) it seems the same as apply[T](c:T) and what's the type of T when I write val d=B{println(1);2} I can write many lines here! because T means generic,so it can be Int,String,user defined class Apple,Orange... and

问题 I am trying to get tensorflow for java to work on Scala. I am use the tensorflow java library without any wrapper for Scala. At sbt I have: If I run the HelloWord found here, it WORKS fine, with the Scala adaptations: import org.tensorflow.Graph import org.tensorflow.Session import org.tensorflow.Tensor import org.tensorflow.TensorFlow val g = new Graph() val value = "Hello from " + TensorFlow.version() val t = Tensor.create(value.getBytes("UTF-8")) // The Java API doesn't yet include
