## Jupyter使用
|
||||||
|
|
||||||
|
安装Anaconda并启动一个环境之后,如何让Jupyter Notebook在我们要的环境中启动呢?
|
||||||
|
|
||||||
|
- 激活目标环境
|
||||||
|
```
|
||||||
|
conda activate myenv
|
||||||
|
```
|
||||||
|
- 安装 ipykernel(如尚未安装)
|
||||||
|
为了让 Jupyter Notebook 能识别该环境中的 Python 解释器,你需要在该环境中安装 ipykernel:
|
||||||
|
```
|
||||||
|
conda install ipykernel
|
||||||
|
|
||||||
|
# 或者使用 pip
|
||||||
|
|
||||||
|
pip install ipykernel
|
||||||
|
```
|
||||||
|
- 注册环境内核
|
||||||
|
将该环境注册为 Jupyter 的一个内核(kernel),这样启动 Jupyter Notebook 后就能选择这个内核:
|
||||||
|
```
|
||||||
|
python -m ipykernel install --user --name myenv --display-name "Python (myenv)"
|
||||||
|
|
||||||
|
# 这里 --name 指定内核的名称,--display-name 是在 Jupyter Notebook 界面中显示的名称,你可以根据需要自定义。
|
||||||
|
```
|
||||||
|
- 启动 Jupyter Notebook:依然在激活后的环境中,启动 Jupyter Notebook:
|
||||||
|
```
|
||||||
|
jupyter notebook
|
||||||
|
```
|
||||||
|
- 启动后,你在新建 notebook 时可以选择刚刚注册的内核 “Python (myenv)” 来确保使用该环境的 Python 解释器。
