我是在使用bert==0.09的时候，遇到这个问题

原因：

numpy和h5py版本兼容问题，网上说h5py 官方已修复合并到 master 分支，但是还没发新版，在发版之前可以用降级 numpy 的方法跳过这个问题。

所以我找到适合我的应用场景的一组版本，问题就解决了。

解决：

pip3 install --upgrade h5py==2.9.0
pip3 install --upgrade numpy==1.14.2
# 备注：肯定有其它的版本配合，我这没有过多测试

# 另：Linux下解决，mac下 仍然会有报错

bug还原

#首先安装bert==0.09
pip3 install bert==0.09
# 然后，在查看帮助命令的时候报错：
bert-base-serving-start --help

  from ._conv import register_converters as _register_converters

重点是：

h5py/__init__.py:36: FutureWarning: Conversion of the second argument of issubdtype from `float` to `np.floating` is deprecated. In future, it will be treated as `np.float64 == np.dtype(float).type`.

然后重新修改下版本后就没问题了！

注意：

        系统环境下，可能有其它的包依赖numpy，在切换numpy版本时，需要注意有木有版本ERROR,如我的环境中就有这个问题：

所以这时候，一定要做好取舍，因为h5py报错，也只是 FutureWarning，是在未来的版本中会不支持，但目前并不影响程序运行，所以，还是要根据实际情况来选择，或者还有一个办法，分多套虚拟环境进行部署。
