Error with Detectron2 when using run_net.py

[dsg637]

Hello,
Thanks for sharing the code. For running the model using run_net.py I face the following error that seemingly related to Detectron2:

Exception has occurred: ImportError /home/user/miniconda3/envs/pytorch/lib/python3.9/site-packages/detectron2/_C.cpython-39-x86_64-linux-gnu.so: undefined symbol: _ZNK2at6Tensor7reshapeEN3c108ArrayRefIlEE File "/home/user/vtn/slowfast/models/head_helper.py", line 8, in <module> from detectron2.layers import ROIAlign File "/home/user/vtn/slowfast/models/video_model_builder.py", line 14, in <module> from . import head_helper, resnet_helper, stem_helper, vtn_helper File "/home/user/vtn/slowfast/models/__init__.py", line 6, in <module> from .video_model_builder import ResNet, SlowFast # noqa File "/home/user/vtn/slowfast/utils/misc.py", line 21, in <module> from slowfast.models.batchnorm_helper import SubBatchNorm3d File "/home/user/vtn/run_net.py", line 5, in <module> from slowfast.utils.misc import launch_job

I'm wondering because I have installed all the required packages and the versions of the installed packages are as follows:

Hi @dsg637,
Most packages have been upgraded since we published this code, so there might be backward compatibility issues installing the latest versions. Specifically, the Detectron2 and fvcore versions we used back then were:

detectron2 @ git+https://github.com/facebookresearch/detectron2.git@c25b53d07c0b8ce3544fd7e2dbf0b3d5bf257b08
fvcore @ git+https://github.com/facebookresearch/fvcore@acbf982ac666fbc78428b8f5c668f03754ff4ff1

I hope this will solve the issue you are facing.
