我在6个月前编写了以下代码，它似乎工作正常。但是，现在，我得到以下内容::
〜/ astroconda / lib / python3.5 / site-packages / astroquery / sdss / init .py：28：UserWarning：Experimental：SDSS尚未重构，以使其API与之匹配其余的astroquery（但几乎就在那里）。 warnings.warn（“实验：SDSS尚未重构以获得其API”
〜/ astroconda / lib / python3.5 / site-packages / astroquery / sdss / core.py:857:VisibleDeprecationWarning：不建议在不指定编码参数的情况下读取unicode字符串。设置编码，使用None作为系统默认值。

错误。不确定我做错了什么/不同......
