Hi @vrevenge0,

This is caused by transformers ≥ 4.42 introducing a module that requires torch._C._distributed_c10d, which is not included in Windows ROCm PyTorch builds.

it's still in the broken range (4.42–4.55.x).

Option 1 — Upgrade (recommended)

pip install "transformers>=4.56.0"

Option 2 — Downgrade

pip install transformers==4.41.2
Verify with:

python -c "from diffusers.models.autoencoders.vae import DecoderOutput; print('OK')"

Let us know if either works!
