which neuromancer version does it require?

[lk1983823]

Thank you for your code. But when I run example1, it runs into an error.
When it runs to
dataset = Dataset(nsim=nsim, ninit=0, norm=args.norm, nsteps=args.nsteps, device='cpu', sequences=sequences, name='closedloop')
it shows:
TypeError: object.__new__() takes exactly one argument (the type to instantiate)

I find the Dataset is imported from neuromancer.dataset, which has no this Class now.
My neuromancer version is 1.2.
Can you help? Thanks.
