Does anyone know what is the reason for this?

Hey @zhongdonglin! Yes, it seems like you are missing the lhwloc libraries.

Check that you have all the dependecies:
sudo apt install mesa-opencl-icd ocl-icd-opencl-dev gcc git bzr jq pkg-config curl clang build-essential hwloc libhwloc-dev wget -y && sudo apt upgrade -y

Also, it seems like it seems like you have CUDA export FFI_USE_CUDA=1? If so, make sure that you have set it up correctly: https://lotus.filecoin.io/tutorials/lotus-miner/cuda/.

I´m converting this into a discussion, and we can troubleshoot there instead 😄

I am reinstalling the graphics card driver and recompiling.

[zhongdonglin]

This problem still occurs

Oh, my god. I downloaded the wrong golang package, I downloaded 386 instead of amd64.Sorry.

[rjan90]

Aha, no worries! Glad that you figured it out 😄
