Undefined symbol Error

Hi

I'm trying to test the model and then use it for inference. I'm recieveing this error. I've tried mutliple version fo python with no success - pytohn 2.7, 3.5, 3.6 and 3.7

Ubuntu 16.04 Python 3.6 Cuda 10.1

python3.6 upsnet/upsnet_end2end_test.py --cfg upsnet/experiments/upsnet_resnet101_cityscapes_w_coco_16gpu.yaml --weight_path ./model/upsnet_resnet_101_cityscapes_w_coco_3000.pth

3.6.9 (default, Jul 3 2019, 15:36:16) [GCC 5.4.0 20160609] Traceback (most recent call last): File "upsnet/upsnet_end2end_test.py", line 44, in <module> from upsnet.dataset import * File "upsnet/../upsnet/dataset/__init__.py", line 1, in <module> from .cityscapes import Cityscapes File "upsnet/../upsnet/dataset/cityscapes.py", line 32, in <module> from upsnet.dataset.json_dataset import JsonDataset, extend_with_flipped_entries, filter_for_training, add_bbox_regression_targets File "upsnet/../upsnet/dataset/json_dataset.py", line 53, in <module> import upsnet.bbox.bbox_transform as box_utils File "upsnet/../upsnet/bbox/bbox_transform.py", line 15, in <module> from .bbox import bbox_overlaps as bbox_overlaps_cython ImportError: upsnet/../upsnet/bbox/bbox.so: undefined symbol: _Py_ZeroStruct

Any help would be great, thanks!

Please try to rebuild all cython modules manually and make sure the python version matches the version you wish to run inference (i.e., use python3.6 setup.py build_ext --inplace)
