Hello Julien,

Oftentimes with IDEs, you will have to select the right Python interpreter for your project. Since you have installed NEST through conda, you should select the python interpreter you used while creating that. This link might help: http://docs.spyder-ide.org/current/faq.html#using-existing-environment

Also, you will have to add the NEST site-packages path in your $PYTHONPATH environment variable somewhere in your IDE for it to be able to recognise NEST. I do not have any experience using Spyder, so I am not entirely sure how to do that.

All the best!

Dear Sir, Dear Madam,

I am currently trying to install NEST in order to be able to use it within an IDE, like Spyder. For the moment I am only able to do the following:
open Terminal
python3
import nest

This works when I use it in the terminal of the computer, but when I open Spyder and execute the following:
import nest
neuron=nest.Create("iaf_psc_alpha")
neuron.get()

I get the following error message in the IPython console:
runfile('/Users/julienballbe/NEST/untitled0.py', wdir='/Users/julienballbe/NEST')
Traceback (most recent call last):

  File "/Users/julienballbe/NEST/untitled0.py", line 11, in <module>
    neuron=nest.Create("iaf_psc_alpha")

AttributeError: module 'nest' has no attribute 'Create'

I am using a Macbook pro M1Max, MacOS 12.0, Spyder 5.1.5, Python 3.9.7.
I followed the instruction for building nest on your website (https://nest-simulator.readthedocs.io/en/latest/installation/mac_install.html) and used your recommendation for M1 macs (https://nest-simulator.readthedocs.io/en/latest/installation/conda_tips.html).

I  build Nest following your instruction, the only error I got was when I ran :

(nest-simulator-dev) julienballbe@pclnrs241 NEST % make installcheck
