What I have already tried with no luck:

change Python version from 3.6 to 3.8 (https://github.com/microsoft/LightGBM/pull/3393#issuecomment-691691309)
change Boost version from 1.74 to 1.70 and 1.67
remove std::move from https://github.com/microsoft/LightGBM/pull/3443#discussion_r507728708

How to reproduce: simply change gcc to clang here
https://github.com/microsoft/LightGBM/blob/7e2f353df4ee6b7a17a653122ab5a549f8e8d0f7/.vsts-ci.yml#L22

It seems we have several CUDA bugs to fix.
Maybe we can summarize them into one issue, for easily tracking?

It is not CUDA bug, but bug with our original OpenCL GPU version.

I want to add that the gpu_source job is working with Clang 7.0.0 on Ubuntu 20.04 on Travis (https://travis-ci.org/github/microsoft/LightGBM/jobs/753978660#L7). So maybe the issue is limited to a subset of clang versions and not all of clang.

Allowing tests to fail and running our CI script further, we can see that all examples work OK but example Notebook fails with LightGBMError: No OpenCL device found error.
