Docker Hub 镜像加速器

国内从 Docker Hub 拉取镜像有时会遇到困难，此时可以配置镜像加速器。Docker 官方和国内很多云服务商都提供了国内加速器服务。

Ubuntu 16.04+、Debian 8+、CentOS 7+

创建或修改 /etc/docker/daemon.json：

terminal hint tools

	import socket
	from threading import Thread

	def echo(conn, addr):
	with conn:
	print('#4. Connected by', a/ddr)
	print('processing data')
	while True:
	data = conn.recv(1024)
	if not data: break

	def evaluate(test_loader, model, criterion, n_iter=-1, verbose=False, device='cuda'):
	"""
	Standard evaluation loop.
	"""

	n_iter = len(test_loader) if n_iter == -1 else n_iter
	modulo = 0 if verbose else -1
	batch_time = AverageMeter('Time', ':6.3f')
	losses = AverageMeter('Loss', ':.4e')
	top1 = AverageMeter('Acc@1', ':6.2f')
