jupyter配置venv

1. 激活存在的venv
2. pip install ipykernel
   安装过程中可能出现如下错误

ERROR: Could not find a version that satisfies the requirement prompt-toolkit!=3.0.0,!=3.0.1,<3.1.0,>=2.0.0 (from ipython>=5.0.0->ipykernel) (from versions: none)
ERROR: No matching distribution found for prompt-toolkit!=3.0.0,!=3.0.1,<3.1.0,>=2.0.0 (from ipython>=5.0.0->ipykernel)

需要先安装prompt-toolkit，注意版本

3. python -m ipykernel install --user --name aaa --display-name “aaa”
4. 刷新 jupyter页面，然后在右上角的new下拉就可以看到aaa啦
