The lack of QuantXXX wrappers (tico/quantization/wrapq) for submodules of Qwen3-VL causes PTQQuantizer: no quantization wrapper for XXX exceptions in tico.quantization.prepare.
This Confluence page contains a script for checking which submodules of Qwen3-VL have QuantXXX wrappers in tico/quantization/wrapq and which don't.
