Purpose

Merging of #48413 introduced two independent runtime errors in the Multi-Modal Models (Extended Generation 3) test group (CI 11817).:

  1. NameError: name 'List' is not defined
  2. AttributeError: 'MiniCPMV' object has no attribute 'all_tied_weights_keys'

This PR aims to resolve the first one. The other bug will be fixed in another PR.

The root cause was that a remote HF python file resampler.py defined a function with a returning value of a List without importing that class into the module.

Test Plan

pytest -v -s "models/multimodal/generation/test_common.py::test_single_image_models[minicpmv_25-test_case100]"
pytest -v -s "models/multimodal/generation/test_common.py::test_single_image_models[minicpmv_25-test_case101]"
pytest -v -s "models/multimodal/generation/test_common.py::test_single_image_models[minicpmv_25-test_case102]"

Test Result

Before:

FAILED models/multimodal/generation/test_common.py::test_single_image_models[minicpmv_25-test_case100] - NameError: name 'List' is not defined
FAILED models/multimodal/generation/test_common.py::test_single_image_models[minicpmv_25-test_case101] - NameError: name 'List' is not defined
FAILED models/multimodal/generation/test_common.py::test_single_image_models[minicpmv_25-test_case102] - NameError: name 'List' is not defined

After:
Passed

@tc-mb are you going to fix it soon on HF Hub? If not we will need to patch or disable the tests to keep CI green

There is a PR already on HR side: https://huggingface.co/openbmb/MiniCPM-Llama3-V-2_5/discussions/79/files

…s for MiniCPM-V 2.5 remote code

openbmb/MiniCPM-Llama3-V-2_5's remote resampler.py annotates with List
without importing it, relying on the alias leaking from
'from torch.nn.functional import *'. Recent torch uses builtin generics and
no longer re-exports it, so loading the model in the HF runner raises
NameError.
