Summary
qwen3_5_moe) deployments.preprocessor_config.jsonexists in the HF repo before starting inference.Why
Qwen3.6 models fail deterministically in SGLang when the repo does not include the processor metadata required by Transformers. Checking this before deployment avoids wasting GPU time and prevents repeatedly retrying a model that cannot start.
HF/network probe errors remain retryable: inconclusive checks return no classification and the scheduler continues through the normal deploy/retry path.
