osx-arm64: missing random number generators
Due to a cross-compiling issue in the conda-forge NEST package, some random number generators are not available if you are using macOS arm64 architecture. The available generators are the Mersenne Twister generators mt19937 and mt19937_64.
Note
We recommend using Mamba (https://mamba.readthedocs.io). Mamba has the advantage of installing conda packages and environments more quickly and can be used as a complete drop-in replacement for conda.
To keep your mamba setup tidy, we recommend that you install NEST into a separate environment together with Python packages that you will use when working with NEST; see also our Tips for installing NEST with Mamba.
To install the latest version of NEST in a new environment called
ENVNAME
, just runmamba create --name ENVNAME -c conda-forge nest-simulator
To install additional packages into the environment, just list them together with
nest-simulator
.mamba create --name ENVNAME -c conda-forge nest-simulator jupyterlab seaborn
To see all NEST versions available via conda, either run
mamba search -c conda-forge nest-simulator To install a specific version e.g., NEST 2.18.0, run
mamba create --name nest_2_18_0 -c conda-forge nest-simulator=2.18.0=*
The syntax for this install follows the pattern:
nest-simulator=<version>=<build_string>
.Activate your environment:
mamba activate ENVNAME
Note the following:
We currently provide NEST with thread-based parallelization on conda-forge. This should suffice for most uses on personal computers.
