Please provide more details about your environment and what you are trying to do. Unfortunately that error message alone is not nearly enough to understand what is going on.

Hello, I met the same error while I was trying to run the inference with the provided pre-trained model (res50).

Traceback (most recent call last):
File "test_panoptic.py", line 16, in
import seamseg.models as models

It seems like when we import _backend which is a cpython compiled file. There is some function definition missing.

This is what I did :
git clone and python setup.py install

python -m torch.distributed.launch --nproc_per_node=1 test_panoptic.py --meta ../model/metadata.bin --log_dir ../log/ ../model/config.ini ../model/seamseg_r50_vistas.tar /imgs/ ../output/

The requirements are met.

I have:
python 3.6
PyTorch 1.1.0
CUDA 10.1
Ubuntu 18.04 with GCC 7.5

Thanks, if you could help
