Check pandas.__version__:
检查pandas.__version__：
In [76]: import pandas as pd
In [77]: pd.__version__
Out[77]: '0.12.0-933-g281dc4e'
Pandas also provides a utility function, pd.show_versions(), which reports the version of its dependencies as well:
Pandas 还提供了一个实用函数，pd.show_versions()，它也报告其依赖项的版本：
In [53]: pd.show_versions(as_json=False)
