Autoscheduler error after multiple iterations

Troubleshooting
#1

I was trying the autoschedule example for arm and encountered the following error after searching for multiple iterations:

RuntimeError: Compilation error:
/tmp/tmpg0b9kf8c/net/devc.o: file not recognized: file format not recognized
collect2: error: ld returned 1 exit status

I found somebody posted this error before, but it was due to wrong compilation flag. Obviously it is not the case here because this autoscheduler has run several iterations without problem.

I was doing experiment at tvm master branch, commit 75d9b78054ca005f95dbbd02dea1395a8c28eac5

#2

Can you provide a minimal reproducible script? And what platform you were tuning?

#3

@comaniac I was following this guide and did not modify any line of code: Auto-scheduling a Neural Network for ARM CPU — tvm 0.8.dev0 documentation
