Error when running ./build-scalehls.sh

[Fiwo735]

Following the steps mentioned in the README, I cloned the repo, cd into it, and tried to build it using ./build-scalehls.sh. I got the following error when trying with Ninja installed:

Synchronizing submodule url for 'polygeist'
>>> Unified MLIR, Clang, and ScaleHLS build...
ninja: error: loading 'build.ninja': No such file or directory

I then disabled Ninja to try to run with make and I got a similar error:

Synchronizing submodule url for 'polygeist'
>>> Unified MLIR, Clang, and ScaleHLS build...
makeL *** No targets specified and no makefile found. Stop.

I use Conda to manage my environment and I have the following library versions:

• Python: 3.6.7
• CMake: 3.23.2
• Ninja: 1.11.0
• Clang: 3.4.2
• LLD: 14.0.4

It is likely some silly error on my side, but given I run into issues on the literal first step of the guide, I am a bit lost on what to try or change, so I would be very happy to get some help here, thanks!

Hi @Fiwo735, I'm not sure what is happening here. Could you try to manually create the build folder and config cmake following the commands in the script?

[hanchenye]

You should be able to start from here:

Hi @hanchenye, thank you very much for your quick response! Below is the output when trying to manually build:

Seeing that the error comes from unknown arguments to clang++, or more precisely /usr/bin/clang++ (which is likely outdated), I realized that my Conda environment hasn't installed a new version for clang++ and only for clang. That might be a rare case, but it might be useful to update the README with clang++/clangxx as a prerequisite, to prevent people using Conda from having a similar issue.

After adding clangxx as a requirement for my environment and cleaning the build/ directory, I was able to run ./build-scalehls.sh. After around 30 minutes of compilation, the end of the logs printed to terminal from building the project can be seen below:

I was able to sucessfully run the HLS C/C++ example polybench/gemm, however, when trying the Pytorch Model pytorch/resnet18 one, I got the following output:

    from torch_mlir.dialects.torch.importer.jit_ir import ClassAnnotator, ModuleBuilder
ModuleNotFoundError: No module named 'torch_mlir'

Am I missing some more dependencies or was the build process not actually fully successul?

[hanchenye]

Hey, great to know that the script is working!

On many testing machines, including my own one, the gettimeofday.c test case is failing but apparently on your machine it passes. You can follow #51 and run build-scalehls.sh again to finish the process.

For the PyTorch models, torch-mlir is more like an upstream tool instead of a part of scalehls, so torch-mlir is not a submodule and not built by build-scalehls.sh. I'd suggest to use the hash in https://github.com/hanchenye/scalehls#compiling-pytorch-model to build torch-mlir first to have the samples in pytorch/resnet18 working.

Hi,

I would like to follow up with this question, when I use the hash in github link to build torch-mlir and I always got the error saying "fatal error: 'ATen/native/quantized/cpu/packed_params.h' file not found"
I am using Ubuntu 22.04, python 3.8.0.
Could you please help?
Thanks
