C4W1 Stuck in Exercise 4 tl.parallel

I went to tl.parallel documentation, and still don’t know how to set it up. tl.parallel assumes we are passing the input and target, and we are also telling it the output from these which are input and target, but I cannot figure out if that means we need to pass tl.parallel((input, input),(target,target)) or
tl.parallel(input, input, target, target) or tl.parallel(input,target, input, target)

Any help will be appreciated.

I figured it out, I just needed to pass the encoder, and decoder
