Import Error: Chamfer 3D undefined symbol

[matthiasjaeger95]

When testing the pretrained model with the pcn dataset, the following error code occurred:

INFO - 2022-08-04 11:52:32,038 - test_pcn - Length of test dataset:0 Traceback (most recent call last): File "test_pcn.py", line 108, in <module> test() File "test_pcn.py", line 34, in test model_module = importlib.import_module('.%s' % args.model_name, 'models') File "/home/matthias/anaconda3/envs/AttN/lib/python3.8/importlib/__init__.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 1014, in _gcd_import File "<frozen importlib._bootstrap>", line 991, in _find_and_load File "<frozen importlib._bootstrap>", line 975, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 671, in _load_unlocked File "<frozen importlib._bootstrap_external>", line 843, in exec_module File "<frozen importlib._bootstrap>", line 219, in _call_with_frames_removed File "/home/matthias/Netzwerke/PointAttN/models/PointAttN.py", line 8, in <module> from utils.model_utils import * File "/home/matthias/Netzwerke/PointAttN/utils/model_utils.py", line 13, in <module> from utils.ChamferDistancePytorch.chamfer3D import dist_chamfer_3D File "/home/matthias/Netzwerke/PointAttN/utils/ChamferDistancePytorch/chamfer3D/dist_chamfer_3D.py", line 20, in <module> import chamfer_3D ImportError: /home/matthias/anaconda3/envs/AttN/lib/python3.8/site-packages/chamfer_3D-0.0.0-py3.8-linux-x86_64.egg/chamfer_3D.cpython-38-x86_64-linux-gnu.so: undefined symbol: _ZNK3c106IValue23reportToTensorTypeErrorEv
I'm using torch 1.8.2, cue 11.4 and tensorflow 2.8.2.

Any ideas what the error could be?

Thanks in advance.

Hi! It seems you have not compile the 3rd-party modules [ChamferDistancePytorch]successfully. Please compile Pytorch 3rd-party modules ChamferDistancePytorch before test the project. A simple way is provied in README.md.

[matthiasjaeger95]

Hello, thank you for the fast answer! When I compile ChamferDistancePytorch again I get the following message in the end. I have assumed that this is correct.

Installed /home/matthias/anaconda3/envs/AttN/lib/python3.8/site-packages/chamfer_3D-0.0.0-py3.8-linux-x86_64.egg Processing dependencies for chamfer-3D==0.0.0 Finished processing dependencies for chamfer-3D==0.0.0

Yes，It seems you have compile the modules successfully. If you still can't complete the test, we are sorry that we have not meet the same problem. However, we find a similar situation in the official project. We hope it will be helpful to you.
