Using the release/2.8 branch, the system is Ubuntu 22.04,
the GPU is AMD Radeon RX 9070 XT,
and it was compiled with ROCM 7.0.0 (tagged as rocm-libraries 7.0.0) for miopen.

Hi @WsqRichards, what steps did you follow to build ROCm and specifically MIOpen from source? For reference, the recommended build system is TheRock which you can use to build from source or pull in the prebuilt torch 2.8 wheels available here https://rocm.nightlies.amd.com/v2-staging/gfx120X-all/torch/.

I compiled PyTorch's release/2.8 branch using the source code. My system is Ubuntu 22.04 and the GPU I used is RX9070. I compiled the repositories llvm_project (https://github.com/ROCm/llvm-project), rocm-systems (https://github.com/ROCm/rocm-systems), and rocm-libraries (https://github.com/ROCm/rocm-libraries). According to the README file, I compiled these three repositories (version 7.0.0 of ROCm). After the three repositories were compiled, I compiled the source code of PyTorch's release/2.8 branch successfully. After the compilation, I wrote a test program and encountered the error as shown above.

Another question: Does ROCM 7.0.0 support the specific release version of PyTorch (I need to compile the source code)?

[harkgill-amd]

It looks like there's a mismatch between the CK and MIOpen libraries that you're using. rocm-all-libs-build/rocm-install/lib/libMIOpen.so.1 expects symbols from your CK library but those don't exist due to the mismatch. Could you share the MIOpen/build/CMakeCache.txt from your build or any relevant build logs, would want to make sure CK is being properly found and linked during the MIOpen build. Having an older CK or an existing installation in /opt/rocm/lib/ can also lead to these types of linking errors so make sure to remove those before building MIOpen.

Does ROCM 7.0.0 support the specific release version of PyTorch (I need to compile the source code)?

ROCm 7.0.0 does support Pytorch 2.8.0 and works fine when using the standard ROCm repo packages. For reference, these are the CK and MIOpen packages pulled in through the standard install,

OK, I will provide the relevant CMake files for compiling miopen.
There is a question: In the rocm-libraries repository (with the tag as rocm-7.0.0 version), which version of the CK library should be used for compiling miopen through source code (the CK library in the rocm-libraries repository seems not to have been migrated yet)?
I am using this version of the CK library: https://github.com/ROCm/composable_kernel/tree/rocm-7.0.0)? After the source code compilation is successful, is the compilation of miopen correct?

This would be https://github.com/ROCm/pytorch/tree/release/2.8 up to commit 64359f5.

I was able to build ROCm from source using TheRock + the release/2.8 branch with no issues. If you need to build from source, are you able to give TheRock a try? Building rocm-systems and rocm-libraries from source individually isn't a workflow that we recommend as TheRock was created specifically to ensure developers don't run into the dependency issues between libraries like MIOpen and CK.
