My Docker image for OpenPose.

The original Dockerfile is from here.

• base image to nvidia/cuda:11.1.1-cudnn8-devel-ubuntu20.04.

• install cmake via apt.

• qtbase5-dev not installed.

Only critical ones.

• Hardware

  GPU : GeForce RTX 2060 SUPER
  

  Turing architecture.

• OS

  Ubuntu 20.04.2 LTS
  

• nvidia-driver

  nvidia-driver-460
  

• Build image and wait.

  This will take some time...

  docker-compose build

• Add volumes to docker-compose.yml

• Exec

  In terminal.

  docker-compose up -d
  docker-compose exec openpose bash

  In container.
  --display 0 is needed.
  See the docs for the options.

  openpose.bin --display 0 <other options>

• or Run

  --display 0 is needed.
  See the docs for the options.

  docker-compose run --rm openpose openpose.bin --display 0 <other options>

Cuda check failed (804 vs. 0): forward compatibility was attempted on non supported HW

Occurred when running openpose.bin inside the container.
Error by mismatch of nvidia-driver and the installed CUDA version.
Update to a driver that fits the installed CUDA version.
Reinstalled nvidia-driver to 460 from 450 on my local device.

Unable to init server: Could not connect: Connection refused

Disable GUI.
Pass --display 0 option when running.

A lot of Warnings when building caffe and openpose

Occurred when building docker image.
Warnings because building for every known GPU architectures including deprecated ones.
It still works.
Docker cannot access to GPU devices when build. Tried to specify it but did not work.
