fork的仓库如何和父父仓库同步
应该是第二次问这个问题了：
git remote -v
git remote remove upstream
git remote add upstream [email protected]:Image-Py/image.git
git remote add upstream [email protected]:Image-Py/imagepy.git
git remote add upstream https://github.com/Image-Py/imagepy.git
git fetch upstream
git merge upstream/master
git push
