提示：ImportError: Missing optional dependency ‘tables‘. Use pip or conda to install tables.

stack overflow回答：
I ran into the same thing. The error tells you (unhelpfully) that the missing package is called tables when in fact, it’s called pytables. Doing conda install pytables is all I needed to do to be able to read h5 files with pandas.
提示安装pytables

网上流行的方法：

conda install pytables
pip install tables

pytables和tables都尝试安装，仍未解决问题

pip install tables==3.5.2

降低版本后问题解决
