今日开始学习深度学习，参考书《动手学深度学习》，在Anaconda Prompt中依次执行过以下代码：
conda env create -f environment.yml
conda activate gluon
jupyter notebook
第一次报错，显示jupyter不是内部或外部命令
尝试以下方法，参考https://blog.csdn.net/weixin_41813895/article/details/84750990
conda install ipykernel
python -m ipykernel install --name gluon
(gluon) D:\anaconda\anaconda>jupyter notebook
Traceback (most recent call last):
File "D:\anaconda\anaconda\envs\gluon\Scripts\jupyter-script.py", line 10, in <module>
sys.exit(main())
File "D:\anaconda\anaconda\envs\gluon\lib\site-packages\jupyter_core\command.py", line 247, in main
command = _jupyter_abspath(subcommand)
File "D:\anaconda\anaconda\envs\gluon\lib\site-packages\jupyter_core\command.py", line 134, in _jupyter_abspath
'Jupyter command `{}` not found.'.format(jupyter_subcommand)
Exception: Jupyter command `jupyter-notebook` not found.
再次打开jupyter notebook失败，显示Exception: Jupyter command jupyter-notebook not found.
求各位帮助解决一下。
