callisto 0.7

安装

可以安装callisto from pypi：

pip install callisto

对Python2.7、3.4、3.5、3.6进行了测试。

基本用法。

典型的用法是在虚拟环境中激活它：

$  virtualenv venv
...
$  source venv/bin/activate
(venv) $  callisto
Successfully installed a new jupyter kernel "venv":
{
  "env": {},
  "language": "python",
  "display_name": "venv",
  "argv": [
    "/Users/colin/venv/bin/python",
    "-m",
    "ipykernel",
    "-f",
    "{connection_file}"
  ]
}
See /Users/colin/Library/Jupyter/kernels/venv/kernel.json to edit.

jupyter服务器现在有一个名为venv的内核选项。

命名内核。

您还可以给内核一个更具描述性的名称：

(venv) $  callisto -n pete
Successfully installed a new jupyter kernel "pete":
{
  "env": {},
  "display_name": "pete",
  "argv": [
    "/Users/colin/venv/bin/python",
    "-m",
    "ipykernel",
    "-f",
    "{connection_file}"
  ],
  "language": "python"
}
See /Users/colin/Library/Jupyter/kernels/pete/kernel.json to edit.

jupyter服务器现在有一个名为venv和pete的内核选项。

正在删除内核。

有时候你可能想整理一下果仁。

(venv) $  callisto -d
Deleted jupyter kernel "venv" from /Users/colin/Library/Jupyter/kernels/venv/kernel.json:
{
  "argv": [
    "/Users/colin/venv/bin/python",
    "-m",
    "ipykernel",
    "-f",
    "{connection_file}"
  ],
  "env": {},
  "language": "python",
  "display_name": "venv"
}

jupyter服务器将不再具有名为venv的内核。

缺乏勇气。

卡利斯托不想太聪明。

(venv) $  deactivate

$  callisto
Usage: callisto [OPTIONS]

Error: The environment variable VIRTUAL_ENV is not set (usually this is set
automatically activating a virtualenv).  Please make sure you are in a
virtual environment!

查看现有内核。< EH3>

如果您忘记了关于内核信息的信息性消息，您可以稍后看到它。

$  source venv/bin/activate

(venv) $  callisto --list
No kernel found at /Users/colin/Library/Jupyter/kernels/venv/kernel.json

(venv) $  callisto -l --name pete
Found kernel "pete" at /Users/colin/Library/Jupyter/kernels/pete/kernel.json:
{
  "display_name": "pete",
  "language": "python",
  "argv": [
    "/Users/colin/venv/bin/python",
    "-m",
    "ipykernel",
    "-f",
    "{connection_file}"
  ],
  "env": {}
}

调整PYTHONPATH。

对于独立的内核，您可能希望从一个目录运行所有笔记本， 但是使用项目目录中的代码。

(venv) $  callisto -n pete --path=$(pwd)
Successfully installed a new jupyter kernel "pete":

{
  "argv": [
    "/Users/colin/venv/bin/python",
    "-m",
    "ipykernel",
    "-f",
    "{connection_file}"
  ],
  "language": "python",
  "env": {
    "PYTHONPATH": "/Users/colin/projects/pete:PYTHONPATH"
  },
  "display_name": "pete"
}
See /Users/colin/Library/Jupyter/kernels/pete/kernel.json to edit.

现在pete内核将能够从文件夹/Users/colin/projects/pete导入。
