WARNING:root:Corpus not found for cycle

[jiangjingzhi2003]

Hi, I am new to fuzzbench. When I was running experiment, I keep getting this warning : WARNING:root:Corpus not found for cycle:1. Is that an issue for my experiment? And how should I resolve that?

I don't have this warning for cycle 0: INFO:root:Setting up coverage binaries INFO:root:Starting measure worker loop for 104 workers INFO:root:Starting one measure worker loop INFO:root:Retrieved 2 unmeasured snapshots from measure manager INFO:root:Starting one measure worker loop INFO:root:Measurer worker: Got request aflplusplus harfbuzz_hb-shape-fuzzer_17863b 17 0 from request queue INFO:root:Retrieved 0 measured snapshots from response queue INFO:root:Measuring cycle: 0.

Extras: {'fuzzer': 'aflplusplus', 'benchmark': 'libxml2_reader', 'trial_id': '18', 'cycle': '0'}

But then I keep getting this warning for rest of cycles

Here is part of logs has warning: INFO:root:Retrieved 0 measured snapshots from response queue INFO:root:Measuring cycle: 1.
