imvoxelnet for mono_det_demo

[yujimori1967github]

I am interested in One-Stage Monocular 3D Object Detection, and I am watching it with great interest.
I was able to get "FCOS3D: Fully Convolutional One-Stage Monocular 3D Object Detection" working by running mono_det_demo.py.

Similarly, we believe that ImVoxelNet can detect indoor images. Please tell me how to make it work like the demo.

I wrote the code like below, but an error occurred.
