[TVM Discuss] [Questions] Relay Gradients

[Thomas V via TVM Discuss]

Hello,

I have been toying around with the gradient relay transformation and wondered 
if I am doing something wrong to get a rather elaborate gradient:
![linear|690x247](upload://wgrWF1xcKY67TwFabk6Rn5MAC4c.png) 

gets transformed into:

![grad_linear|469x500](upload://mTnPXYdgholApZHbIaN6W1mjIcQ.png)

I must admit that that is a bit more than I had hoped for...

Now I realize that symbolic differentiation is bound to create very complex 
graphs, but I can't help but wonder whether I did something wrong. (And there 
might be optimization passes disconnecting some of it.)

I am grateful for any hint you might have.

Best regards

Thomas
