`torch._C._distributed_c10d` how to solve if e.g. on Termux

### Bug

`docling -v` etc. problem resulting in: `No module named 'torch._C._distributed_c10d'; 'torch._C' is not a package` at see below.

### Solution and cause:
Solved via https://github.com/pytorch/pytorch/issues/152285#issuecomment-3289016639 that is `pip install transformers -U ` if e.g. on Termux, where `apt install python-torch` is missing that DISTRIBUTED compilation flag.

### Ref, full error if not above (downgrade or upgrade of `transformers`)

```
