how to use jupyter-connect-repl ??

[kurt-steiner]

eh, I use emacs-jupyter not very long
what the usage of jupyter-connect-repl? I don't know what is the "file holding the connection"
is that something "ipynb" edited in jupyter?
I tried the file opened in brower, but in emacs, the error is

Assertion failed (and transport ip)

ps: sorry for my poor English

The "file holding the connection" is the connection file as explained here.

jupyter-connect-repl is used when you would like to connect to an already launched kernel, e.g. launched through some other method besides the ones offered by emacs-jupyter.

You pass jupyter-connect-repl the path to the JSON connection file which has the IP, type of transport (e.g. tcp), and the port numbers to connect to the kernel. Those paths are usually in the Jupyter runtime directory, the directory returned by a call to jupyter --runtime-dir at the command line.
