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。

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！
参考：https://bcolz.readthedocs.io/en/latest/intro.html#bcolz-at-glance
按照上面依次安装还是不行？
$ pip install bcolz

这次的报错还是很长很吓人，根据报错，把numpy装一下就好了。
$ pip install numpy
