ImportError (undefined symbol)

[SiddharthRaoA]

Hey, I'm getting the following error when I try to run the test code. Is this a version error or a bug in the code itself? If it is a version error, could you let me know what versions of pytorch and torchvision should I use?

I tried with multiple versions but got the same error every time. I have tried torch 0.4 + torchvision 0.2.1 (the one given in the CornerNet repo) and torch 1.1 + torchvision 0.2.1 (the one given in this repo), but both seem to give the same error.

Please let me know what changes I should make to be able to run the code. Thanks in advance!

Hi it seems like the version problem. I would suggest you to check pytorch version. If you would like to use the latest pytorch please see my last reply for the issue.

Best, Junyu

Hi Junyu,

May I know what did you reply to him? I have the same issue with trying multiple combination but still failed.

Hi, I am getting the same error. I followed your readme (+ https://github.com/soap117/DeepRule/issues/3). I even tried installing it on a blank linux docker image but still getting this error. (Pytorch in version 1.1.0). Has anyone managed to solve this problem?

I'm getting a similar error. undefined symbol: _ZTIN3c1021AutogradMetaInterfaceE

was this ever resolved?

Hi

I am also getting the same error as below while training and also while running the command (python manage.py runserver 8800), Please suggest a solution for this ASAP

File "/content/drive/MyDrive/DeepRule/models/py_utils/_cpools/top_pool.py", line 6, in bootstrap imp.load_dynamic(name,file) File "/usr/lib/python3.8/imp.py", line 342, in load_dynamic return _load(spec)

ImportError: /content/drive/MyDrive/DeepRule/models/py_utils/_cpools/top_pool.cpython-36m-x86_64-linux-gnu.so: undefined symbol: _ZTIN3c1021AutogradMetaInterfaceE

[soap117]

compile the corner net package as the guideline.

[soap117]

Do not use the uploaded complied files, and download the latest codes.

Hi, I am also facing the same problem "ImportError: /chart_extraction/DeepRule/models/py_utils/_cpools/top_pool.cpython-36m-x86_64-linux-gnu.so: undefined symbol: _ZTIN3c1021AutogradMetaInterfaceE" during evaluation (test_pipe_type_cloud.py). I followed the Readme file compiling the Corner Pooling Layers as well as NMS. has anyone solved this error yet?
