I’m trying to get pytorch to use my AMD RX vega 56 on Ubuntu 20.04, and to do that I have to compile it with ROCm. My actions are as follows:
git clone https://github.com/ROCmSoftwarePlatform/pytorch.git
cd pytorch/
git submodule init
git submodule update
git submodule sync
git submodule update --init --recursive
tools/amd_build/build_amd.py 
USE_ROCM=1 MAX_JOBS=16 python setup.py install --user

I also followed this tutorial 7 on my first attempt to get this to work, so the respective packages should be already installed.
The build_amd.py command printed as its last line “Successfully preprocessed all matching files.”, so it seems to have run correctly. However, in the output of setup.py I found the following lines:

Can't exec "/opt/rocm-4.0.0/llvm/bin/clang++": No such file or directory at /opt/rocm-4.0.0/hip/bin/hipconfig line 141.

-- Could NOT find HIP: Found unsuitable version "0.0.0", but required is at least "1.0" (found /opt/rocm-4.0.0/hip)
HIP VERSION: 0.0.0

and later
--   USE_ROCM              : OFF

I’m assuming I’ve forgotten to install some HIP-related library, but I can’t figure out which one. I will attach the full compiler log at the end of this post. Let me know if I need to post more information, and of course, your help is greatly appreciated!
