llvm error

[kailiu9]

I have build tvm with CUDA and LLVM support(LLVM_CONFIG = /mypath/llvm-config). when I use nnvm.compiler.build(..., target="llvm", ...), there is no problem. But if I use target="cuda" then report error：attribute after last parameter! i32 (%0*, i8*, i32*, i8*, i8*) @fuse_sqrt_elemwise_add_compute_ LLVM ERROR: Broken function found, compilation aborted!
When I build tvm only with CUDA, there is no error.
Anyone can help me? Thank you!

Code: I use the example of Get Started with NNVM.

Are you saying that you have this error when running nnvm/tutorials/get_started.py ? If not please provide a script gist to reproduce the error.

You might want to try the llvm nightly version here http://apt.llvm.org/ Note that TVM requires LLVM version >=4.0

I had same issue before. My solution is reinstalled system, then build llvm only (instead of ld tools, etc), then it works well. I guess the problem is around llvm/system tools.

To tqchen: Yes, I use nnvm/tutorials/get_started.py, then have this error. And I used the llvm 5.0.

Thank you @antinucleon , In addition to reinstalled system, are there some other solutions? Because, there are others using this machine.

I don’t know, but seems the problem is around llvm tools.

closing this due to inactivities. Possibly an llvm rebuilt from source might help

Please see if #582 helps to resolve the issue
