'NoneType' object is not callable

When I try to run the code (the command included in this GitHub repo for 3D tracking):

How can I solve this error?

Please do the following guide:

cd $CenterTrack_ROOT/src/lib/model/networks/
# git clone https://github.com/CharlesShang/DCNv2/ # clone if it is not automatically downloaded by `--recursive`.
cd DCNv2
./make.sh

Incredibly, I have cloned in a Docker image, and it restarted it. However, the solution was rebooting the computer (I guess some HW was updated, cause I installed CUDA, CUDnn and Nvidia driver in this last Docker image commit).

I have now running the demo.py, thanks!

I had the same error. I first thought I compiled DCNv2 correctly and in my case it was not. so I ran python setup.py build develop command manually inside my DCNv2 folder and it compiled DCNv2 successfully. It solved the problem and I got rid of the error. hope this helps.

In my case, https://github.com/3846chs/DCNv2.git version solved the same problem
