Fix runtime error when Qwen2-VL model is prompted with prompt with more
than one image. The runtime error was:
File "text-generation-inference/server/text_generation_server/models/custom_modeling/qwen2_vl.py", line 459, in get_position_ids
text_pos_ids = torch.arange(text_length, device=d)
RuntimeError: upper bound and larger bound inconsistent with step sign
The error was caused by text_length variable going to negative value
when multiple images caused multiple loops in the get_position_ids
function's main loop.
The error is a simple logic mistake where next_image_pos is initialized
as relative offset from current_pos, but was used like it was absolute
position from zero.
* feat: support multidimensional position ids on batch to enable cuda graphs on qwen2-vl
* fix: only check model type if config exists
* fix: adjust sharding and lm head logic
* fix qwen2 failure in intel cpu
