Julia Package Flux

General Usage
1

using Flux

f(x) = 3x + 2

df(x) = gradient(f,x)[1]

df(2)

when I am running this code, I am getting an error - LoadError: UndefVarError: gradient not defined.

However, if I change gradient by Flux.gradient, it works fine.
Can anybody tell me why this is happening?

Unexported functions need to be qualified with the package name.

gradient should be exported by default when you use Flux. You may be on a very old version, so check your packages with ] st at the REPL.
