无法使用 anaconda 从 jupyter notebook 导入水印

Question

我看到我安装了水印：

(testenv) ?  ~ conda install watermark
Fetching package metadata ...........
Solving package specifications: .

# All requested packages already installed.
# packages in environment at /Users/myuser/anaconda3/envs/testenv:
#
watermark                 1.5.0                    py36_0    conda-forge
(testenv) ?  ~

然后我运行jupyter notebook它启动：

(testenv) ?  ~ jupyter notebook

但是当我在 jupyter 中运行时，我无法导入水印，我做错了什么？

from __future__ import print_function
from distutils.version import LooseVersion as Version
import sys

importlib.import_module('watermark')

你尝试使用%load_ext watermark？显然，库水印的使用是通过 jupyter 的魔法命令完成的。
