SWu commented on issue #4519: [Relay] VM executor doesn't work with higher order gradient function URL: https://github.com/apache/incubator-tvm/issues/4519#issuecomment-566206902 ParialEvaluate + DeadCodeElimination segfaults for me I actually have a lot of trouble running gradient functions (even first_order) through the VM, it seems some pass doesn't play nicely with gradient function and DeadCodeElimination always triggers a segfault somewhere in 0.6.0 release. I didn't have this problem before all of the compile optimization passes were added, but I also haven't been able to find a minimal reproducible example. All I know is that DeadCodeElimination at some point during CalcDep probably tries to visit some invalid reference variable. It's only with generated gradient functions that I run into this, regular feed forwards seems to be fine.
