使用Arcface时需要安装bcolz，

【机翻】bcolz提供了可以在内存和磁盘上压缩的列式分块数据容器。列存储允许高效地查询表，以及廉价的列添加和删除。它基于NumPy，并将其用作与bcolz对象通信的标准数据容器，但它还支持向HDF5/PyTables和pandas数据帧导入/导出工具。

$ sudo pip3.7 install bcolz

解决：报错已经提示了，依次手动安装好它需要的依赖就可以

$ sudo pip3.7 install setuptools-scm
$ sudo pip3.7 install cython
$ sudo pip3.7 install bcolz

pip 已经20.1.1版本了，还是不够智能！
