# What does this PR do?

Throw an error if `getattribute_from_module` can't find anything - to avoid `RecursionError: maximum recursion depth exceeded while calling a Python object`.


**New error:**

```bash
ValueError: Could not find MarkupLMForMaskedLM neither <module 'transformers.models.markuplm' from '/home/yih_dar_huggingface_co/transformers-ydshieh/src/transformers/models/markuplm/__init__.py'> in nor in <module 'transformers' from 'src/transformers/__init__.py'>!
```
