second grad error #165
Comments
Related to #155, any fixes on this? |
I will try to make a temporary solution in the weekend. In long term this part will be replaced by MXNet's NDArray subsystem which we are working on now. |
We should still fix this. It is a quite important feature.

@jermainewang I found the reason now. Look at here: link. The function pushed into gradient record is unwrapped version. Which means that tape cannot record operations there. I think this change is due to performance concern. Should we fix it or wait autograd runtime? (By the way, does autograd runtime support higher order derivatives? |
@lryta Do we have any follow-up on this? |
