LLVM error when import torch_tvm after building pytorch and torch_tvm from source

[DreamChaserMXF]

Environments: Ubuntu16.04 LTS, Python 3.6.9, LLVM 8.0, GCC 5.4, Pytorch Nightly version (build from source), torch_tvm master branch.

Successfully import tvm, but encounter error when import torch_tvm:

Bottom of the screen is '__init__.py' of package torch_tvm.

Anyone has any advice?

Does this clash with import tvm?

Does this clash with import tvm?

No, it doesn't. import tvm can be executed without any error and warning. It seems like tvm was successfully compiled, but torch_tvm was somehow corrupted.

@bwasti Anything on top of your head?

Same issue here on Ubuntu 18.04.

I also have this issue on ~~18.04~~16.04 with LLVM 9.0.0. It appears to be related to this issue: https://github.com/ziglang/zig/issues/67, which also appears elsewhere in different forms.
