错误：pandas 0.23.4 has requirement python-dateutil=2.5.0, but you'll have python-dateutil 1.5
问题描述
1、Ubuntu16.04下 安装pycaffe，执行下面语句
for req in $(cat requirements.txt); do sudo pip install $req; done
2、出错，如下所示：
pandas 0.23.4 has requirement python-dateutil>=2.5.0, but you'll have python-dateutil 1.5 which is incompatible.
matplotlib 2.2.3 has requirement python-dateutil>=2.1, but you'll have python-dateutil 1.5 which is incompatible.
jupyter-client 5.2.4 has requirement python-dateutil>=2.1, but you'll have python-dateutil 1.5 which is incompatible.
解决方法：
3、执行python-dateutil更新：
sudo pip install --upgrade python-dateutil
已经是最新版本
再次执行下面的安装语句，发现还是未解决上面的问题。
for req in $(cat requirements.txt); do sudo pip install $req; done
4、 最终解决方案：
进入caffe下的python目录，执行下面语句：
ls
sudo gedit requirements.txt打开requirements.txt，修改python-dateutil项
将
python-dateutil>=1.4,<2
改为
python-dateutil
再次执行安装命令，成功！
成功解决！
