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 File "/home/haoliu/.conda/envs/py36/lib/python3.6/site-packages/seamseg/models/init.py", line 1, in from .resnet import * File "/home/haoliu/.conda/envs/py36/lib/python3.6/site-packages/seamseg/models/resnet.py", line 6, in from inplace_abn import ABN File "/home/haoliu/.conda/envs/py36/lib/python3.6/site-packages/inplace_abn/init.py", line 2, in from .abn import ABN, InPlaceABN, InPlaceABNSync File "/home/haoliu/.conda/envs/py36/lib/python3.6/site-packages/inplace_abn/abn.py", line 6, in from .functions import * File "/home/haoliu/.conda/envs/py36/lib/python3.6/site-packages/inplace_abn/functions.py", line 5, in from . import _backend ImportError: /home/haoliu/.conda/envs/py36/lib/python3.6/site-packages/inplace_abn/_backend.cpython-36m-x86_64-linux-gnu.so: undefined symbol: _ZN6caffe26detail37_typeMetaDataInstance_preallocated_32E

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
