Jupyter 集成 go 内核

基于 gophernotes.

依赖

• Go 1.9+ - including GOPATH/bin added to your PATH (i.e., you can run Go binaries that you go install).
• Jupyter Notebook or nteract
• ZeroMQ 4.X.X - for convenience, pre-built Windows binaries (v4.2.1) are included in the zmq-win directory.
• pkg-config

ZeroMQ的安装

# centos
yum install zeromq

其他系统，见 https://zeromq.org/download/#linux

安装 gophernotes

以centos为例

$ go get -u github.com/gopherdata/gophernotes
$ mkdir -p ~/.local/share/jupyter/kernels/gophernotes
$ cp $GOPATH/src/github.com/gopherdata/gophernotes/kernel/* ~/.local/share/jupyter/kernels/gophernotes

1. 服务器 go get 有翻墙问题的，可以参考https://shockerli.net/post/go-get-golang-org-x-solution/，通过修改 GOPROXY 环境变量 的方式解决。
2. 命令目的是：在jupyter内核新建gophernotes的文件
3. cp 的源目录,需要你自己确定 gophernotes package 被安装到哪个位置。然后检查 ~/.local/share/jupyter\kernels\gophernotes\kernel.json 文件 的 "argv" 数组的 gophernotes 路径是否正确，如 "/root/go/bin/gophernotes"

将 gophernotes 添加至 PATH，执行 gophernotes 命令，得到如下输出，说明安装成功。

$ gophernotes

最后重启 Jupyter 完成。

supervisor

如果你是用supervisor帮你管理jupyter的进程，那你需要将go相关的环境变量写入进程的.ini配置文件。举例：

[program:jupyter-notebook]
...
...
environment=ENV="dev",PATH="/usr/local/go/bin:/root/go/bin:/usr/bin:$PATH",GOPROXY="https://goproxy.cn",GO111MODULE="on"
