我在Instagram上发布的不是方形照片 https://instagram.com/p/7M7aBoNTcM/

通过Instagram api使用https _ // api.instagram.com/v1/media/1061415553965831926_2141618404?access_token=Token尝试获取所有照片,并为该图像提供下一个standard_resolution网址:https://scontent.cdninstagram.com/hphotos- xfa1 // // t51.2885-15 // s640x640 // sh0.08 E35 // 11821940_708988202567623_81870409_n.jpg

没有用于裁剪的参数,但是我在图像的顶部和底部得到了带有白线的图像.

为什么在Instagram的网站上发送我的图像(矩形),但api返回带有白线的正方形？

如何在没有白线的情况下发布不是方形图片？

我是Python和Linux的新手,我需要帮助,我尝试使用matplotlib以下列方式显示一个简单的图:

from matplotlib import pyplot as plt

plt.plot([5,6,7,8], [7,3,8,3])
plt.show()

但是,当我运行时python3 test.py,我得到以下输出:

/usr/local/lib/python3.4/dist-packages/matplotlib/backends/backend_gtk3agg.py:18: UserWarning: The Gtk3Agg backend is known to not work on Python 3.x with pycairo. Try installing cairocffi.
