undefined symbol: THPVariableClass

Hello,

I want to run the code. So, at first I built the MultiScaleDeformableAttention Module and it is installed successfully.

But when I run the track.py, I get the following error:

How can I solve the problem?

[timmeinhardt]

What are your torch, torchvision, CUDA and CUDNN versions? I assume there is a version mismatch.

[isaryo]

Hi. I'm having the same problem. torch = 1.8.0 torchvision = 0.9.0 python3.7.8, CUDA11.2, cudnn=8.1.1 The GPU used is RTX6000. Is it incompatible?

[timmeinhardt]

Please follow the INSTALL instructions step by step and install the correct versions. This repository does not support torch=1.8.0.

Hi. I'm having the same problem. torch = 1.8.0 torchvision = 0.9.0 python3.7.8, CUDA11.2, cudnn=8.1.1 The GPU used is RTX6000. Is it incompatible?

hi~I have the same problem too.Have you solved it? torch=1.5.0 torchvision=0.6.0 cuda=10.2 cudnn=7.6.5 I think the version is correct，but the problem happened.

[timmeinhardt]

This is most likely a version mismatch. For example, CUDNN 7.6.7 does not support CUDA 10.0. At least according to this support matrix.

Hi, I also have the similar problem. When I finish Install acoording to the instruction, I excute train commond: python src/train.py with \     mot17 \     deformable \     multi_frame \     tracking \     output_dir=models/mot17_deformable_multi_frame Then I got the error: File "/data/ldap_shared/home/s_zyd/trackformer-main/src/trackformer/models/ops/functions/ms_deform_ attn_func.py", line 11, in <module> import MultiScaleDeformableAttention as MSDA ImportError: /ldap_shared/home/s_zyd/.pyenv/versions/anaconda3-2019.07/envs/trackformer-breast/lib/py thon3.7/site-packages/MultiScaleDeformableAttention-1.0-py3.7-linux-x86_64.egg/MultiScaleDeformableAt tention.cpython-37m-x86_64-linux-gnu.so: undefined symbol: _ZN3c104cuda20getCurrentCUDAStreamEa My environment: python=3.7.3 torch=1.5.0 torchvision=0.6.0 cuda=10.2 nvidia-cudnn=8.2.0.51 GPU: NVIDIA GeForce RTX 3090

@timmeinhardt @tiancola @mhnasseri Can you help me to solve it?
