1）PaddleHub和PaddlePaddle版本：PaddleHub1.6.1，PaddlePaddle1.7.1 2）系统环境：ubuntu18.04, python3.7.3

出现方式：初次配置，先后pip安装了PaddlePaddle和PaddleHub。然后，命令行输入 hub，报出以下错误。hub 其他命令依旧。

Traceback (most recent call last): File "${ANACONDA_HOME}/bin/hub", line 6, in from paddlehub.commands.hub import main File "${ANACONDA_HOME}/lib/python3.7/site-packages/paddlehub/commands/init.py", line 26, in from . import config File "${ANACONDA_HOME}/lib/python3.7/site-packages/paddlehub/commands/config.py", line 30, in HubServer() File "${ANACONDA_HOME}/lib/python3.7/site-packages/paddlehub/common/decorator_utils.py", line 24, in synced_func return func(*args, **kwargs) File "${ANACONDA_HOME}/lib/python3.7/site-packages/paddlehub/common/decorator_utils.py", line 35, in _get_instance _instance[cls] = cls(*args, **kwargs) File "${ANACONDA_HOME}/lib/python3.7/site-packages/paddlehub/common/hub_server.py", line 59, in init lock.flock(fp_lock, lock.LOCK_EX) File "${ANACONDA_HOME}/lib/python3.7/site-packages/paddlehub/common/lock.py", line 38, in flock self.lock.flock(fp, cmd) OSError: [Errno 9] Bad file descriptor
