ROS development on MacOSX using docker

We need to use docker-machine to handle USB ports inside the docker.

Docker Machine (0.16.1)

• Install docker-machine: https://docs.docker.com/machine/install-machine/
• Docker version: 18.09.2, build 6247962
• Install virtualbox >= 6.0

import torch
import torch.nn as nn
import torch.optim as optim
import torch.nn.functional as F

Some notes on launching distributed computations with PyTorch

• Inside a docker container
• Using NCCL and TCP or Shared file-system
• PyTorch version: 1.0.1.post2
• 2 Nodes / 3 GPUs

Docker container

We need to run the container with --network=host option

How to remotely debug C++ program from VSCode

Good references:

• https://medium.com/@spe_/debugging-c-c-programs-remotely-using-visual-studio-code-and-gdbserver-559d3434fb78
• https://github.com/dmrauch/vscode-cpp-remote-debug/

The setup:

• Local: MacOSX
• Remote: Ubuntu 16.04 in Docker
