[AutoTVM] Failed to run autotvm example on GEMM

[Airtnp]

I was trying to use code from https://zhuanlan.zhihu.com/p/75203171 (it's a Chinese post, but it's essential the same as Writing tunable template and Using auto-tuner) with modified size 4096^3. However, in my AWS instance, it keeps reporting tons of similar error like this

I tried with code in Writing tunable template and Using auto-tuner and it also reports errors like

What's wrong with the code? Thank you for your help!
