Segmentation fault (core dumped) #5

Hi Xinyi, Thanks for your great work! I met segmentation fault when I am trying to train D3D model. The DCN is installed as follows: Installed /scratch/users/rji19/.conda/envs/pytorch1.2.0/lib/python3.7/site-packages/D3D-1.0-py3.7-linux-x86_64.egg Processing dependencies for D3D==1.0 Finished processing dependencies for D3D==1.0

I think DCN has no problem but when I'm training the process cannot pass this function output = DCN.deform_conv_forward(). So I think there is must something wrong in DCN that I don't know. Could you provide some cues about this problem ? Thank you

I have the same question. Have you solved it?

I think maybe cuda version. My cuda10.0 is failed

I don't know. I tried different cuda versions.

Same problem here.

Have you tried to reduce im2col_step? batch_size must be dividable by im2col_step.

deform_conv_cuda.cu checks if the input tensor is contiguous stored in memory. Did you tried to call tensor.contiguous() before calling the DCN module?

rongleiji commented 3 years ago

Yes, it is necessary
