I'm trying to install and use NEST on google Colab, but it's not importing:
!pip install -Uqq nest
!pip install -Uqq nestml
!pip install -Uqq pysilsub
import nest
import nestml
import numpy as np
import matplotlib.pyplot as plt
from pysilsub import observers
from nestml.network import Network
from nestml.models import ConeNakaRushton
Am I able to use NEST on Google Colab?

Hey Alvin,
You may have to restart the kernel because the installation was installed via a child
shell process and have yet to be loaded into the current process that the kernel is
running on.
IIRC, it is called “Restart runtime” in Google Colab.

NEST is not pip installable, using !pip install -Uqq nest will install a
"network stack tester" https://pypi.org/project/nest/
You will have to follow another installation route. I'm not sure which one
is recommended for Google Collab. Perhaps the conda or CMake installation?

Thank you Hans,
I'd like to share the nest code I've created with teammates, and run the
code within our Google Colab code base. So, I've gotten nest and nestml to
import, but run an error whenever I try to call a submodule:

Hi Alvin,
You can use NEST simulator with the help of conda in google colab.
To do this, the package `condacolab`
(https://pypi.org/project/condacolab/) needs to be installed:
!pip install -q condacolab
import condacolab
condacolab.install()
Then you can use `conda` or `mamba`:
!mamba install -c conda-forge nest-simulator
NEST should now be usable:
import nest
nest.__version__
Best
