我在将 GeoPandas 中的 DataFrame 从 EPSG:4326 投影到笔记本中的 EPSG:3857 时遇到了一些麻烦。我的原始数据集如下所示：

可视化：
当我尝试将其重新投影到 EPSG:3857 时：
reprojected = texas.to_crs(epsg=3857)
我得到了一些巨大的数字作为输出（显然不是正确的坐标）：
0 POLYGON ((-10847609.18711273 2985418.174237921...
1 POLYGON ((-10866188.46006429 2998482.12034216,...

关于为什么如此简单的重投影无法正常工作的任何想法？我尝试使用各种形式的to_crs 函数，包括texas.to_crs({'init': 'epsg:3857'})，并三重检查texas.crs 是否设置为{'init': 'epsg:4326'}。
作为参考，我使用的是 GeoPandas 0.5.1 和 PyProj 2.3.1。 编辑：我也试过升级到 GeoPandas 0.6 只是为了好玩，但没有骰子:(。
提前致谢！
