I want to use multi-threading function in NEST simulator (version 2.20.1). However, it gives a warning No multithreading available, using single threading. Can anyone help me to solve it?
I install NEST simulator using conda command
conda create --name nest -c conda-forge nest-simulator
Below is my code and output:
