Conda ¶

Anaconda provides packages for NEST Desktop. and NEST Simulator. These packages can be installed with Conda (from conda-forge). Since NEST 3, the API server (i.e. NEST Server) is included which is necessary for NEST Desktop.

Prequistion for conda-forge¶

Conda-forge is a collection of packages led by the community (https://conda-forge.org/). By default conda cannot install packages from the conda-forge.

Add channel for conda-forge:

conda config --add channels conda-forge
conda config --set channel_priority strict

Install with Conda¶

Create a Conda environment called nest3 and install NEST Simulator:
```
conda create -n nest3 nest-simulator
```
Activate the Conda environment nest3:
```
conda activate nest3
```

Install the dependencies for the API Server of NEST Simulator:

conda install flask flask-cors RestrictedPython gunicorn

Install NEST Desktop
```
conda install nest-desktop
```

Start with Conda¶

Start NEST Server as the back end:

The API Server for NEST Simulator is referred to as NEST Server.
```
nest-server start
```
NEST Server is now running at http://localhost:52425.

Note

Before you start nest-server, you have to set these environment variables in bash:

export NEST_SERVER_DISABLE_AUTH=1
export NEST_SERVER_ENABLE_EXEC_CALL=1
export NEST_SERVER_DISABLE_RESTRICTION=1

For more information read the full documentation of NEST Server here.

Start NEST Desktop (in another terminal session):
```
nest-desktop start
```
NEST Desktop is now started and available in the web browser at http://localhost:54286.

The installation is now complete! Now you can start constructing networks for the simulation!
