define and use functions f1 and f2 with parameters

You can pass parameters to the functions in tf.cond() using lambda and the code is as bellow. x = tf.placeholder(tf.float32) y = tf.placeholder(tf.float32) z = tf.placeholder(tf.float32) def fn1(a, b): return tf.mul(a, b) def fn2(a, b): return tf.add(a, b) pred = tf.placeholder(tf....

Defining separate behaviours in different platforms

Different platforms can have separate implementations of the same method. This example also illustrates how build tags and file suffixes can be used together. File main.go: package main import "fmt" func main() { fmt.Println("Hello World from Conditional Compilation Doc!&...

`Could not deduce (Fractional Int) ...`

The error message in the title is a common beginner mistake. Let's see how it arises and how to fix it. Suppose we need to compute the average value of a list of numbers; the following declaration would seem to do it, but it wouldn't compile: averageOfList ll = sum ll / length ll The problem is...

Dual-purpose modules (refinements or global patches)

It's a good practice to scope patches using Refinements, but sometimes it's nice to load it globally (for example in development, or testing). Say for example you want to start a console, require your library, and then have the patched methods available in the global scope. You couldn't do this wit...

Dynamic refinements

Refinements have special limitations. refine can only be used in a module scope, but can be programmed using send :refine. using is more limited. It can only be called in a class/module definition. Still, it can accept a variable pointing to a module, and can be invoked in a loop. An example show...
