TVMError: Check failed: bf != nullptr: Target llvm is not enabled

ShishoSama · February 1, 2020, 4:38pm

Hello everyone, Hope you are having a great time. I am trying to get the first example running (I’m refering to the tutorials section and the relay_quick_start.html#sphx-glr-tutorials-relay-quick-start-py) using intel_graphics. I have built the TVM with OpencCL support and everything went smoothly without a hitch! However, upon running this snippet :

    opt_level = 3
    target = tvm.target.intel_graphics()
    with relay.build_config(opt_level=opt_level):
        graph, lib, params = relay.build_module.build(
            mod, target, params=params)

I’m faced with these errors :

I’m on windows 10. and have built TVM with “Visual Studio 16 2019” . Any help is greatly appreciated .

Hi @ShishoSama

Please following SOP as below to configure the LLVM properly

https://docs.tvm.ai/install/from_source.html

Hope helps,

Hi thank you very much.
last night I tried installing it using Visual Studio 16 2019 without a hitch and everything went smoothly. but since it seems, tvm needs llvm to work properly, I decided to build tvm with LLVM ON.
I followed the instrcutions at the link you kindly provided and built llvm from source and then tried building tvm using Ninja. However this is where it fails. Upon using the ninja to build it fails with these errors (building with vs2019 also fails as well):

I got this error because of GCC in my Path! I built llvm from source, and added the bin directory to the path, however, I couldnt find any clang related files! so I downloaded the prebuilt LLVM, and added it to my PATH. The problem here is solved but a new one is generated which can be seen [here]: TVM wont compile using llvm on windows
