How can i change a Distribution?

[CAI23sbP]

❓ Question

How are you @araffin ?
I have two questions

1. If I want to change distribution , how can I do it?

Here is my situation
I made an agent that was based on PPO(diagonal dist) by imitation learning library( behavioral cloning)
And then, Finetuning the pretrained model use a 'gSDE' (StatedependentDist)
It is right to change a sde_sample_freq from 1 to n?

2. How can i create a normalized observation(for demonstration data)? Is it okay to use a VecNormEnv?
   Might i get any hit about the above issues?

Thank you!

should be fine

Is it okay to use a VecNormEnv?

that's one solution. But if you have a fixed dataset, you can precompute the normalization.
