Hi @justanotherfangirl , and welcome to the Nengo forum! :smiley:

Based on the last line in the response you provided, I think the issue could be related to the used python version ( I suspect you are using the 3.8), as it is mentioned in What’s New In Python 3.8 :

The function time.clock() has been removed, after having been deprecated since Python 3.3: use time.perf_counter() or time.process_time() instead

So it may be useful to check again the used python version, downgrade it (if it’s indeed the 3.8) and test again.

Thanks, it works perfectly now!

How did you solve it?
I am still getting the same error

Hi @pujapachchigar, and welcome to the Nengo forums. :smiley:

NengoGUI currently supports Python 3.7 and below. If you are using Python 3.8 or 3.9, you will encounter the AttributeError: module 'time' has no attribute 'clock error.

To install and use Python 3.7, I recommend using Miniconda. Once you have that installed, you can use the command:

conda create -n myenv python=3.7

to create a Python 3.7 conda environment. Once the environment is created, do:

conda activate myenv

to activate the environment, then you can install Nengo and NengoGUI by issuing the standard pip install commands. Every time you want to run Nengo, you’ll need to activate and use this Conda environment (but you only have to create it once).
