Dear Maryada,
Am I understanding you correctly that every time you call v_m.GetValue() you get the same results? I am not able to reproduce your results, I get a new value for V_m every time I switch rng_seed, and also if I call v_m.GetValue() a second time with the same seed without doing a ResetKernel.
To test that you are actually setting a new rng seed, maybe do a print(nest.rng_seed) to make sure? What is your output if you type print(nest.rng_type)?
Best wishes, Stine

Dear NEST users,
As I understood from the documentation unless you set the seed using nest.rng_seed, nest.random.normal (for instance) should return the same value
nest.ResetKernel() nest.rng_seed = 21#69696 v_m = nest.random.normal(mean=-51., std=10.) v_m.GetValue()
In this code, I always receive the same v_m value for both cases, if the seed is set as 21 or 69696. The only time it changes is if I remove ResetKernel() call, which then is expected to return different values irrespective of rng_seed. With this code below, I also got the same results irrespective of rng_seed value
nest.ResetKernel() nest.rng_seed = 3333#69696 for _ in range(10): v_m = nest.random.normal(mean=-51., std=10.) print(v_m.GetValue())
So, maybe rng_seed doesn't reflect on nest.random.normal distribution. However, then how can I make sure it draws a different set of values?
-- Thanks and Regards
