tensorboard报错：TensorBoard could not bind to port 6006, it was already in use

问题

训练深度学习时，打开TensorBoard发生报错：TensorBoard could not bind to port 6006, it was already in use ERROR: TensorBoard could not bind to port 6006, it was already in use

tensorboard --logdir='/home/ubuntu/xxx/logs' --port='6006'

报错信息如下：

E1108 13:48:08.055952 139724834817856 program.py:298] TensorBoard could not bind to port 6006, it was already in use
ERROR: TensorBoard could not bind to port 6006, it was already in use

解决方法

关闭之前的端口进程，具体操作如下：
输入：

lsof -i:6006

输出：
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
tensorboa 3094950 ubuntu xx xxxxx xxxxxxxxxx xxxx xxxxxxxxxxxxx (LISTEN)
输入：

kill -9 3094950

再次输入，即可正常使用：

tensorboard --logdir='/home/ubuntu/xxx/logs' --port='6006'
