Open the example golang notebook and make a copy of it. Then, run the first cell to install golang, gophernotes. Then refresh and skip the first cell to test golang in later cells.

It's not working. Throws an error at the end. So, I modified the script to circumvent the error. This takes care of the error(s). But now I do not get the choice of kernels under runtime selection: there is no drop down to choose Go from. 🔥

thank you @sugatoray
it works

How do I install go1.15+ on colab? @korakot
I have corrected the path. It should work now using go1.16
I have corrected the path. It should work now using go1.16
🚀 🚀 I tested it and it works now. 👍
Running the following code block (set as the top most code block) followed by refreshing the browser window/tab with colab-notebook, sets up golang in the notebook environment.
# run this cell first time using python runtime
!add-apt-repository ppa:longsleep/golang-backports -y
!apt update
!apt install golang-go
%env GOPATH=/root/go
!go get -u github.com/gopherdata/gophernotes
!cp ~/go/bin/gophernotes /usr/bin/
!npx degit gopherdata/gophernotes/kernel \
/usr/local/share/jupyter/kernels/gophernotes
# then refresh, it will now use gophernotes. Skip to golang in later cells
Do you think something like this could be used to use an octave kernel in Colab? I was able to install octave and the octave-kernel, but don't know how to make Colab start the octave-kernel.
Thanks,
Rob
Doesn't seem to work currently. Throws an error around go get -u
go: go.mod file not found in current directory or any parent directory.
'go get' is no longer supported outside a module.
To build and install a command, use 'go install' with a version,
like 'go install example.com/cmd@latest'
For more information, see https://golang.org/doc/go-get-install-deprecation
or run 'go help get' or 'go help install'.
@frohro You can get octave-kernel to work if you download the .ipynb and change the first bit of the file in a text editor to
{
"nbformat": 4,
"nbformat_minor": 0,
"metadata": {
"colab": {
"provenance": []
},
"kernelspec": {
"name": "octave",
"display_name": "Octave"
},
"language_info": {
"name": "octave"
}
},
and upload this to google colab. Run the first cell. This downloads the octave kernel and installs it. After the first cell is run, then refresh... You should be able to run octave in the cells.
I came across this while trying to get the kotlin kernel to work...
@cjwomack If you obey the error message, it works.
To build and install a command, use 'go install' with a version,
like 'go install example.com/cmd@latest'
But... I can't finish reconnecting the runtime after reloading the page.
It is stuck in reconnecting, and I can't run anything.
I terminate other sessions, but nothing changes.
@korakot Could you tell me if you can reconnect it?
Not working for me
I have updated the instruction. Now you must do everything in one notebook. The first cell is run as Python. Later cells are run as golang.
