question about init_dones tensor in a2c_common

[WSYANGSX]

hello!
When I was reading a2c_common source code. I find a question. Why we need to initialize self.dones tensor ones? That will mark first translation (s,a,s_,r, done=1). I don't know if this is a mistake. Or I don't understand the code logic correctly.

That doesn't matter. The real dones are actually returned from env.step(). You can look at play_steps() for details.
